How To: Reformat Mac OS X Without a Recovery Disc or Drive
As I've said before, slowing down is not an option for me. At one point, I realized that there were plenty of files on my Mac that I didn't need any more, but too many to delete individually. In other cases, your Mac can be experiencing some major malfunctions: constant crashing, locked controls, slow boot times, missing files, etc.

How To: Trick Your MacBook's Touch ID into Registering Twice as Many Fingerprints for Each Account
While Touch ID has been a part of the iPhone's legacy since 2013, Apple waited until 2016 to add biometrics to its MacBook lineup, and it's not as impressive. An iPhone with Touch ID can register up to five fingerprints, but Macs can only register a maximum of three per account. If that seems unfair, there's an easy trick to doubling that number, meaning six of your fingerprints could unlock your laptop!

Apple's MacBook line of laptops is quite famous for their extensive battery life, thanks to various technologies that Apple has utilized. However, all things must pass, and over time your MacBook's battery will degrade. Certain use scenarios can accelerate the degradation of the battery—from excessive usage to high temperatures to overloading the system—and this can all lead to the untimely obliteration of your battery.

You can use the F1 key to notably dim your Mac's display, but sometimes that just isn't dark enough. If you're working in pitch black conditions, have a migraine or tired eyes, or just want a more comfortable environment, you might want your screen even darker—without making it pitch black.

How To: Get Apple's RSS Visualizer Back as a Screensaver in Mac OS X 10.8 & Higher
Back in the day when computers relied on CRT monitors, having a static image displayed for too long actually resulted in the image being burned into the screen. For this reason, screensavers were developed, which display animated images in constant motion to prevent burning in when you stepped away from your computer.

How To: Add Custom or Pre-Made HTML5 Widgets to Your Mac's Desktop
Apple hasn't been the most avid supporter of widgets over the years. Yes, they added them to the Notification Center in Yosemite, but that requires a drawer to be opened and closed whenever you want to check them. In my search for a better solution, I came across Ubersicht by developer Felix Hageloh.

How To: Unlock Your Mac Using Your iPhone's Touch ID or Lock Screen Passcode
Apple's Touch ID, introduced on the iPhone 5S, has definitely made my life a little easier. Not only can I unlock my device, I can use the tech to log in to websites, make purchases through iTunes, and buy groceries at Walgreens using just my fingerprint. Still, as awesome as Touch ID is, it's pretty limited as to what it can do on native apps.

How To: Hunt Down Space-Hogging Files on Your Mac with Disk Inventory X
I love my MacBook Air, but the fact that it runs on only 128 GB of flash storage causes me to move most of my files to the cloud. I don't mind having to be connected to the internet in order to access my files, but it's definitely a hassle trying to figure out which files I should move in order to save the most space. Usually, I don't even bother even trying until I see the dreaded "Your startup disk if almost full" warning. Currently, the only real way to find your biggest files in Mac OS X ...

This video demonstrates how easy it is to take a screenshot with shortcuts in Mac OS X. Pressing Command-Shift-3 will take a screenshot of the entire screen, while Command-Shift-4 will let you take a screenshot of just a selected area of the screen instead. For the latter, once you use the shortcut, your mouse pointer will turn into crosshairs, and you would click on one point of the screen, then drag and release your mouse to take a capture of the selected area.

I could sit here and try to explain to you how I updated to Lion and then inexplicably dragged the iPhoto application into the trash—and proceeded to empty said trash.
