Color PDF documents are generally great, but may not serve your purpose when you just want black-and-white printouts to save on printer ink. Fortunately, macOS High Sierra and the wonderfully versatile Preview app can convert colored PDFs to black-and-white document with a few clicks.

But there’s a small bug you’ll have to deal with until Apple updates the Preview app and fixes the glitch.

How to Convert Color PDFs to Black-and-White

Thanks to a bug in Preview, there’s an extra step you’ll have to take when converting a color PDF to black-and-white or gray tone: first convert the PDF to JPEG in Preview, and then re-convert that back to PDF as you apply the Quartz filter:

  1. Open a PDF file in Preview.
  2. Go to the File Menu > Export.
  3. In the Export dialog box, you can choose to change the file name in the Export As field. Change the file format to JPEG from the Format dropdown. Click Save and the PDF file is exported as a JPEG.
  4. Open the JPEG again in Preview. Again go to File Menu > Export. Now, change the file format to PDF from JPEG.
  5. Click the dropdown menu next to Quartz Filter and choose Black and White or Gray Tone from the list of filters.
  6. Click the Save button. The file is exported to your specified location as a black & white PDF.

Open the file and you will see...

Processors, operating systems, and programs can all be 32-bit or 64-bit. While 32-bit was once the standard, 64-bit has taken over as technology has progressed.

macOS has been exclusively 64-bit since Mac OS X Lion released in 2011, but Macs are still compatible with older 32-bit software. However, that’s set to change soon.

32-Bit App Support on Mac Will End

Some Mac users have started seeing a vague warning when launching 32-bit apps that the apps “need to be updated by [the] developer to improve compatibility”. And an official Apple support document states that “macOS High Sierra [will] be the last version of macOS to run 32-bit apps without compromise.”

It’s not clear what this “compromise” is (likely some kind of compatibility mode). However, Apple has encouraged users to find 64-bit apps or contact developers of 32-bit apps to encourage them to update.

For now, you can get some key info about your Mac and see which apps are 32-bit so you know which ones may run into issues in the future.

Checking Which 32-Bit Apps May Stop Working Soon

  1. Click the Apple logo in the upper-left corner of your Mac, and select About This Mac.
  2. Select the System Report button.

The dock has an increasingly important role in how you use your iPad these days. It’s an essential part of the new multitasking workflow, letting you run apps in split screen and Slide Over mode and helping you jump between apps faster than ever.

Apple introduced the new functionality in iOS 11. Previously, the dock was merely a row of apps that was accessible through your home screen. Now, you can use it from any app by swiping up from the bottom of the screen.

In iOS 11, you can also add far more apps to the dock. The maximum used to be six, but if you have an iPad Pro, you can now add 15. Regular iPad users can add 13. Lastly, the new dock is divided into two sections. On the left-hand side are apps you’ve pinned there. On the right are recently used apps.

But what if you’d rather use the dock real-estate solely for pinned apps and remove the recently used apps completely? It is possible. Keep reading to find out more.

How to Remove Recently Used Apps From iOS Dock

To stop recently used apps from appearing on your iPad’s dock, follow the instructions below:

  1. Open the Settings app.
  2. Tap on General.
  3. Select Multitasking & Dock.
  4. Scroll down to the Dock section.
  5. Slide the toggle next to Show suggested and recent apps into the Off position.

To reverse the process, just slide the toggle back into the On position.

Note: You can also use the Multitasking & Dock menu to disable split screen functionality and...

Like most online platforms, Facebook is saving your entire search history, but you can easily delete individual searches or wipe your entire search history from your phone or browser.

Much has been written about just how much Facebook knows about you. With its ever-evolving privacy settings, it can be hard to figure out where to go to find the settings you want. Clearing your search history is certainly no exception.

How to Clear Your Facebook Search History

If you tend to visit Facebook in a browser, you can wipe your search history by doing the following:

  1. On your profile page, click the View your activity log button. In a browser the button is on the right-hand side.
  2. In the menu on the left, under Photos and Videos, Likes and Reactions, Comments, click More.
  3. When the menu expands to show all filters, click Search history
  4. You’ll see a full chronological list of everything you’ve searched for on Facebook. You can delete individual searches by clicking the Edit button next to the entry and clicking Delete
  5. You can also wipe your entire search history in one go by clicking the Clear Searches button.

People can head to YouTube to learn about everything from changing guitar strings to Photoshop basics. As such, it’s an excellent way to learn about cybersecurity.

A formal, real-world class may be out of your budget, but the great thing about YouTube videos is that they’re free and versatile. You can watch or listen to them anywhere, such as on your smartphone or tablet during downtime or commute to work.

The best cybersecurity videos give actionable strategies and rich details from respected experts in the field. Here are some good ones you shouldn’t miss.

1. Your Role in Fighting Cybercrime

As the CEO of an internet security consultancy, Theresa Payton oversaw White House IT for George W. Bush. In this video, she offers tips for staying ahead of cybercriminals, thereby empowering her audience.

Payton also strategically uses anecdotes to make her words even more memorable. After watching it, you’ll be significantly more aware of how you can help curb cybercrime with practical behaviors and measures.

Don’t worry about feeling overwhelmed afterward, either. Peyton emphasizes how everyone who uses the internet can help reduce cybercrime through small but effective measures.

2. Innovation in Risk and Cybersecurity

Making progress often involves noticing opportunities others miss. This cybersecurity video explores how all members of an organization must strive for business-driven security.

It’s an important one to watch due to the way it emphasizes collective responsibility for positive change. It’s most applicable to people in the corporate world; however, there are relatable aspects...

You know how it goes: you’re browsing the web, or checking an email, when all of a sudden a message pops up. Your computer, and the data on it, is locked—encrypted by ransomware. Access is denied until you pay the ransom.

Most people know the procedure with ransomware, which is why the criminal coders behind it are finding new and inventive ways to make you pay up. Here are some new types of ransomware that you should be aware of.

1. Talking Ransomware

If your computer is infected with the Cerber ransomware (typically via an email attachment posing as a Microsoft Office document), your data will be encrypted, with each file given a new file extension: .cerber.

Note: Unless you’re in Russia or the Ukraine, or other former USSR nations, such as Armenia, Azerbaijan, Belarus, Georgia, Kyrgyzstan, Kazakhstan, Moldova, Turkmenistan, Tajikistan, or Uzbekistan. If you are situated in these locations, the Cerber ransomware will deactivate.

You’ll know that you’re infected by Cerber as a notice will appear on your desktop. Furthermore, instructions on how to pay will be found in every folder, in TXT, and HTML format. You’ll also find a VBS file (Visual Basic Script) which, when opened, will dictate instructions to you. That’s right: this ransomware talks you through how to pay the ransom and decrypt your data.

2. Play Our Game… Or Else

In April 2018, we saw the PUBG Ransomware which took a different approach to holding your computer to ransom. Rather than demand money for your locked files, the coder...

Over the years, Google has left its humble origins behind to become one of the largest companies in the world, offering a wide range of devices and services.

To keep those services free, Google records data about you and uses it to display targeted advertising—their main source of revenue. As the debate around online privacy ramps up, many people are looking for an alternative.

Fortunately, DuckDuckGo might be the privacy-focused search engine you’ve been looking for.

What Is DuckDuckGo?

DuckDuckGo describes itself as “the search engine that doesn’t track you.” Most search engines collect search data, with Google even linking that data to your account. The recorded data is used to personalize your search results, and to show you targeted advertising. But DuckDuckGo (DDG) doesn’t track you and opts not to personalize your search results.

The site has grown steadily since its inception, going from an average 79,000 daily searches in 2010, to 23.5 million daily and 16 billion total searches as of April 2018. Some of this growth has been down to DDG’s partnerships with browsers like Firefox, and Apple’s Safari. They have also partnered with many Linux operating systems, and have native apps for...

Want to run Android apps on Linux? How about play Android games? Several options are available, but the one that works the best is Anbox, a useful tool that runs your favorite Android apps on Linux without emulation.

Here’s how to get it up and running on your Linux PC today.

Meet Anbox, Your “Android in a Box”

Having access to your preferred Android apps and games brings an exciting new dimension of productivity to your Linux desktop or laptop. Mobile apps are, by design, a lot simpler than those found on desktop operating systems.

This could be just what you’re looking for to improve desktop productivity!

Meanwhile, mobile games are becoming increasingly sophisticated. It makes sense that you might want to continue playing on a different device, especially given the limited battery life of a phone or tablet. Sure, you could plug the device in to recharge, but being able to play the game on your computer could give you an edge.

Several macOS and Windows tools are available for running Android apps. The most common tool for running Android on a desktop is Bluestacks, but this isn’t available for Linux.

Instead, Linux users should try Anbox, a free and open source alternative based on the latest version from the Android Open Source Project (AOSP). Offering a window-based Android environment, complete with apps and games, Anbox uses containers to separate Android from the host operating system (that is, the OS on your computer).

That’s not all; as well as being open source,...

If you’re a big fan of Adobe Lightroom, you probably already know all the tips and tricks to editing awesome photos, but how can you speed up that workflow? How can you save yourself from hours of work when you have a large batch of photos to work on?

This article will show you how to batch edit in Lightroom. We’ll also cover some simple-but-effective tricks you can employ to start racing through batch edits.

And if you’re not sure on the differences between Lightroom and Photoshop, take a look at our comparison of Lightroom vs. Photoshop.

1. Organize Your Library

Once you’ve completed the Lightroom import process, you will usually have a bit of tidying up to do before the real editing begins.

You may have photos which are out of focus, badly exposed, or simply duplicates. One thing that will really speed up your editing process is by filtering out all of the bad or unusable shots immediately.

From the top-right of Lightroom, choose the Library module.

To view each photo individually, select the Loupe View on the bottom left, use the shortcut key E.

To the left of the Loupe view button is the Grid View (shortcut key G). The grid view shows all of your library at once, similar to a folder structure. This is useful, but you won’t need it for this first pass.

In loupe view, all your photos are visible horizontally at the bottom of the screen,...

The Raspberry Pi 3 is a great little computer, far more powerful than the models before it. But did you know you can squeeze even more power out of it? Here’s how to overclock your Raspberry Pi, and push it further than you ever imagined!

Why Overclock Your Raspberry Pi?

A standard Raspberry Pi 3 boasts a 1.2GHz 64-bit quad-core CPU, 1GB RAM, along with a Broadcom VideoCore IV GPU as part of the Broadcom System on a Chip (SoC) BCM2837.

Overlocking the CPU will result in increasing the default Raspberry Pi clock speed from 1.2GHz up to 1.5GHz, depending upon your cooling solution (such as a heat sink). Note that because the Raspberry Pi uses a SoC, you’ll need to adjust RAM to accommodate overclocking.

What’s the point of overclocking a Raspberry Pi? Well, it’s simple: you want to get the most out of it. Several popular tools will work better than intended with overclocking.

Retro gaming: If you’ve been struggling with running Sony PlayStation 1, Sega Dreamcast, or Nintendo N64 games on RetroPie, RecalBox, or whatever retro gaming solution you’ve chosen, overclocking can help considerably.

Kodi: Performance issues with streaming video in Kodi can be overcome thanks to overclocking your Raspberry Pi. If you’re also using a VPN, higher clock speed will help here too.

Exagear: Trying to run Windows software on your Raspberry Pi? Even with the right preparation, overclocking can help here.

Desktop: Raspberry Pi 3 can be used as a standard desktop. Who wouldn’t want a bit...

Android lets you make all kinds of awesome customizations so you can personalize your phone. While some of these tweaks require lots of in-depth work, others are low-hanging fruit and only take a few taps. Custom icons fall into this second camp. In just a few minutes, you can swap the default app icons on your phone for something way cooler.

How to Set Custom Icons for Apps on Android
  1. First, you’ll need to install a compatible Android launcher. Unfortunately, the default launchers on many phones, like Pixel Launcher and Samsung’s launcher, don’t support custom icons. (We’ve taken a look at the best Android launchers if you’re not sure what to use. For this example, we’ll use Nova Launcher.)
  2. After you’ve installed a launcher, set it as your default so you don’t accidentally return to your old one. (When you tap the Home button on your phone, you should see an option to do so.)
  3. Next you’ll need to install one or more custom icon packs from Google Play. You can also import icons manually, but this is a lot slower. (Take a look at some great icon packs for an idea of what’s available. Moonshine is a solid one to try.)
  4. To apply your icon pack, head into the options for your launcher. In Nova Launcher, go to Nova Settings > Look & feel > Icon theme. (Here you’ll see a list of all installed...

Suppose you’ve just got home after a week of skiing in the French Alps. You recorded your adventures on a GoPro, and now you want to share your gnarly jumps and less-than-impressive crashes with the world.

However, before you upload your footage, you probably want to edit your GoPro footage. But which app should you use? Since GoPro Studio ceased to exist at the end of 2017, the decision has become more difficult.

In this article, we detail seven of the best free apps for editing GoPro videos.

1. GoPro Quik

Available on: Windows, Mac

GoPro Studio might not exist anymore, but GoPro Quik is alive and well.

The company has designed the app to be accessible to people who aren’t necessarily experienced video editors—though you’ll still find it useful even if you’ve worked with videos for a long time.

To start, the app will automatically import content from your device as soon as you plug it into your computer. Once your GoPro footage is on your hard drive, you can use Quik to create time-lapses, add panning effects, add sound, and a whole lot more.

If you’re an adrenaline junkie, Quik is also a great tool. It lets you add graphs, charts, and speedometers to show viewers how far, high, or fast you went.

Lastly, because it’s an official GoPro app, Quik makes it easy to update your GoPro devices with the latest firmware.

Using voice control in your life isn’t science fiction. If you know the right “OK Google” voice commands to say to Google Assistant, it can make your life better in ways you’ve never imagined.

In this article, we’re going to take a walk through the typical day of a Google Assistant power user. You’ll see how Google Assistant can streamline your whole day. You’ll learn how it can remove daily annoyances from your life, and how it can even improve your relationships.

1. “Tell me the weather”

As you wake up in the morning, you’re not sure what to wear for the workday. Will it be cold or warm? Will it rain or not? You roll over toward your phone and say, “OK Google, tell me the weather.”

Google assistant tells you (out loud) the day’s weather, and what the forecast looks like for the week.

Using what you learn from Google Assistant, you choose your attire accordingly. Cold but sunny means a good sweater, jeans, and sunglasses.

2. “Play news on TV”

As you sit down on the sofa with your morning coffee, all you have to do is say “OK Google, play the news on my TV.”

Google Assistant casts the latest news from your preferred news sources to the TV you’ve set up in your Google Home app, like a Chromecast device.

You do need to configure your Chromecast...

Google is testing changing the way Google Maps gives out directions. The idea is to make Google Maps sound more human, and employ similar clues as a real person would when asked for directions to a particular location. Which essentially means pointing landmarks.

Thanks to sat navs and smartphones, it has probably been a while since anyone pulled over and asked you for directions. However, when that was a common occurrence, the chances are you would have used memorable landmarks to help drivers remember.

Google Maps Loves Fast Food Chains

Google Maps and other GPS platforms currently don’t do that. Instead, they use a combination of distances and street names. This works, but can lead to you overshooting a turn, especially if you get distracted. So Google is testing a different way of doing things.

Some users have noticed that Google Maps has started naming places of interest when giving directions. These places of interest include fast food restaurants such as Burger King and White Castle. But we have to assume there’s no favoritism here.

This feature hasn’t been advertised, and isn’t listed in the most recent update. And that’s probably because this is just being tested right now. Google told Engadget that this is just one of a number of methods being tested to “make...

Online shopping is so popular since it’s easy and convenient. But isn’t it frustrating when you’ve just purchased something and see the price drop the next day? If you had waited, you’d have saved some cash!

Fortunately, a lot of stores offer a price guarantee for their customers. But it’s hard to keep track of every policy. So what are you to do?

That’s where Paribus comes in and helps you save precious money without the headache. We’ve previously provided a full overview of Paribus, but here are some other compelling reasons to install the app if you haven’t already.

A Note on the Paribus Mobile Apps

Paribus is a service that you can access using a web browser on any device. It’s easy to create an account and start getting those refunds.

For iOS users, they offer a convenient iPhone app as well, so you can check out your savings, stats, and deals at any time. While they once offered an Android version of the app, it’s not currently available on the Google Play Store.

We’ve contacted Paribus regarding this, but they do not have a timeline for the Android app’s return. The reason for this is because most of the service’s traffic comes from desktop users.

So you’ve looked into Amazon Music Unlimited, you know it’s not the same as Amazon Prime Music, and you think it’s better than Spotify and Apple Music.

If you’ve gone ahead and activated a 30-day free trial for Amazon Music Unlimited but aren’t quite sure what to do next, don’t feel bad. Amazon Music’s interface is far from intuitive, and Music Unlimited’s best features can be hard to find.

To help you get more out of your Amazon Music Unlimited subscription, there are a number of tips and tricks you should start making use of straight away…

1. Download Songs for Offline Playback

Like all of the best music streaming services, Amazon Music Unlimited does allow you to download songs for offline playback—but only when using the Android or iOS apps. This means offline playback isn’t available on the Windows, Mac, or Web apps.

There’s no limit to how many songs you can download this way. However, downloaded songs are protected and can only be played through Amazon Music, meaning they can’t be exported to external storage or transferred to any other devices.

To download for offline playback, just go to any song, album, or playlist and open its “More Options” menu (the three dots), then select Download.

To see all of your downloaded music, go to My Music > Offline Music on Android or go to Settings > Offline Music Mode on iOS. On either platform,...

Are you staring down at boxes in your attic filled with old photos? The memories are priceless, but the practical aspects of keeping, maintaining, and sorting through old photo albums can be daunting.

Thankfully there are a number of great solutions out there for digitizing prints. But what’s the best way to scan old photos? Well that depends on the number of old photos you have, your budget, what you intend to do with the photos, and how much free time you have.

Why You Should Scan Old Photos

Taking the time to turn your treasured physical photographs into digital copies isn’t as easy as leaving them in a photo album or box. Even if you love to shoot with film, or hold physical memories in your hands, there are a number of reasons why you may want to consider this option.

  1. It’s easy to damage physical photos. Water damage, discoloration, and accidental tears are all legitimate concerns that could ruin your treasured photos forever. Making digital copies allows you to make as many backups as needed—so you never have to worry about losing your entire family history in the event of a flood or fire.
  2. Photo albums, frames, and storage boxes can take up a lot of space in your home. On the other hand, you can store hundreds of thousands of digital copies on a single external hard drive the size of a deck of cards.
  3. Family photos are meant for sharing. Having digital copies ensures that no one has to...

What would you do if you lost or broke your iPhone tomorrow? Assuming your iPhone is never coming back, you have two options: restore the backup you made, or start over from scratch.

Nobody likes catastrophic data loss, but it happens. Fortunately, you can safeguard against the unthinkable by putting a backup plan into action.

Protect your personal data, Camera Roll, contacts, and more with regular iPhone backups. Here’s what you need to know to do that.

Why Back Up Your iPhone?

Does the thought of losing your iPhone make you feel a little sick? It’s not just the monetary value, since you can replace the hardware. All the data that lives on your smartphone that you’ll never get back is much more valuable.

For most of us, this means personal photos and videos stored in the Camera Roll. And that’s not all: you’d lose documents and other data used by your apps. If you create Pages documents on the go that aren’t stored in iCloud, they’d be gone. If you’re creating art with Procreate on your iPad Pro and you haven’t exported, you’ll lose it.

Fortunately, many services do have cloud backup now, including Apple’s Notes app and third-party productivity tools like Evernote. Despite this, setting up your device all over again and downloading each app manually is a chore.

You can avoid much of this hassle by creating a backup. When the time comes, you can restore your device using...

If you’re using Photoshop for your design projects—creating logos, posters, infographics, or anything else—then you’ll need to know about typography.

Photoshop has a whole lot of tools for getting text onto your page, and making it look incredible. But where do you start?

In this short guide, we’ll walk you through everything you need to know about working with text in Photoshop.

Type Tool Basics in Photoshop

Before we get started, let’s do a quick overview of the absolute basics for working with text in Photoshop.

You add text to a document using one of the Type tools. You can select these in the Toolbar on the left edge of the screen, or by hitting T on your keyboard.

When you select this, the Type options will appear in the Options Bar at the top of the screen. The main ones are:

  • Font Family: Select a font from those installed on your computer (or from Typekit)
  • Font Style: Choose a style for your selected font, such as the Bold or Oblique versions
  • Size: Set the point size for your type
  • Align Text: Set the text to be left, right or center aligned
  • Color: Choose a color for your text
  • Cancel or Commit: Once you’ve added or edited text you must confirm to apply it to your canvas, or cancel to undo or remove it

Each item of text always goes on its own layer. To move or resize the text while editing hold down the Ctrl or Cmd...
