Terminal Tips & Tricks

Macs are generally highly power efficient due to, in part, the optimized sleeping schedule with OS X. Yet in certain scenarios, you might not want your Mac to go to sleep: downloading a huge file, reading a book, reviewing a spreadsheet, analyzing some content on the screen... the list goes on. To resolve this, you can go to System Preferences and mess with the settings, but this can be an annoying process if you need to do it often.

If you've been around computers long enough, you've probably heard the phrase "have you tried turning it off and on again?" This trick usually works because it forces your computer to empty out the contents of its RAM and disk caches when you restart.

OS X is built upon a UNIX foundation, which grants you access to the benefits that UNIX offers, including the standard toolkit (make, gcc, clang, git, perl, svn, size, strings, id, and a lot more) via the command line developer tools, which are an essential if you're a developer. Aside from developers, the command line tools can offer benefits to normal users as well, like the ability to purge RAM for better performance.

If you're seeing "damaged" apps on your Mac, you're not alone. A huge digital rights management blunder in Apple's Mac App Store on Wednesday, November 11th has rendered some apps unusable. When opening certain apps, the following message could be displayed:

You can check stock quotes, make quick calculations, see the weather forecast, get reminders, and view upcoming calendar events all from the Notification Center on your Mac. But if that's all your using it for, you're just barely scratching the surface.

When you think of Terminal, you probably imagine some hacker sitting in front of their computer in a dimly lit room trying to break into an FBI database. In reality, it's just a simple tool that can make using your Mac much easier.

Apple may have made Mavericks more accessible to Mac users everywhere at the fair price of zero dollars, but unfortunately, they made it trickier to create a bootable install drive of the Mac OS X 10.9 operating system.

Apple released the new Mac OS X 10.10 Yosemite in the Mac App Store for everyone to download and install for free on October 16th, 2014, but downloading a 5+ GB file for each of your computers will take some serious time. The best thing to do is download it once and create a bootable install USB drive from the file for all of your Macs.

While you may not have loads of secret files hiding on your computer, there might be one or two items that need a little extra security, like a file of website logins or a folder of risqué photos.

While my desktop is usually neat and organized, it quickly fills up with screenshots each and every day. Usually, I end up putting them in a folder or just trash them, but why not make the entire process of taking and organizing screenshots easier by changing their default save location?

When Google Play Music launched a few years ago, I ditched iTunes and began using the service as my one and only source for listening to my personal music library. While All Access is great, I still prefer the radio feature on Spotify, so I still use that to discover new music.

Yosemite is definitely an improvement over Mavericks, but there are still some painfully obvious and annoying bugs that occur within certain apps.

Yosemite brought a new, Alfred-like Spotlight search to our Macs, but at times I still find myself wanting more out of it. However, after stumbling upon Flashlight by developer Nate Parrot, I am now able to perform Google searches, look up weather, and even enter Terminal commands straight from Spotlight's search bar.

When Yosemite was released, a more detailed boot screen came to your Mac. So now, just like on Apple's mobile devices, you will see a loading bar telling you how far into the startup process you are. Apple also decided to add a black version of this boot screen to newer Macs, leaving those of us who purchased a computer before 2011 out of the loop.

Heartbleed, move over. There's a new bug in town, and this time it's also affecting Mac and Linux computers. It's called Shellshock (its original official title is CVE-2014-6271), and it's currently got a 10 out of 10 severity rating over at the National Cyber Awareness System. While some updates have been issued to fix this bug, they were incomplete, and your system is probably still vulnerable, as it has been for the last probably 20 years.

Continuity is a new feature for iOS 8 and Mac OS X Yosemite which allows users to connect their Apple devices to their Mac in order to access applications, send text messages, receive phone calls, and more while seamlessly switching between devices.

I was kinda disappointed with last year's James Bond movie, Skyfall. Don't get me wrong, it was a solid flick, but only made me jealous with all its super spy hacker stuff.

If you have a Mac running Mountain Lion, I'm sorry to tell you that all it takes to crash almost any app on it is eight little characters.

With the use of Terminal, anyone can run multiple instances of the same application on a Mac. When you have multiple windows open in a web browser, the windows are all running under the same Process ID (PID). But, with multiple instances, each has its own unique PID. So why would you want to run multiple instances of the same app?

When OS X Lion (10.7) debuted last year, a lot of Apple users were dismayed that the "Save As" option had disappeared, replaced by the "Duplicate" function. Most felt that it just wasn't the same, so when Mountain Lion was released, the "Save As" option was brought back… sort of.
