Turn On Screen Zoom for Mac

There are accessibility features built into the Mac that make it easier to see things on screen. One of those settings is called "Zoom," and it lets you magnify the part of the screen that you need bigger. This can be done system-wide, meaning you can zoom in and out no matter what application you're currently running.

Use a Process Monitor to Diagnose Mac or PC Performance Issues

If you're experiencing a dramatic slowdown on your Mac or PC, you may be able to track down the culprit by using a process monitor. This will show you all of the programs and processes currently running on the computer, and how much of your system resources those processes are taking up. If you close out of all programs and still see a process taking up nearly 100% of the system resources, you'll know what's causing the issue. Then you can Google the name of that process and find out how to get it under control.

Verify the Identity of a Website in Your Browser

When browsing the web, you may have encountered a "certificate" warning from your browser. This happens when you're connecting to a site using encryption, and the browser can't verify the identity of that site. Every browser or operating system comes with a preset list of "Certificate Authorities." These authorities could be governments, companies, or other entities that issue identity certificates to websites. This is all part of the SSL encryption process, and it verifies that you're securely connected to the right place.

Fully Uninstall Mac Applications

Uninstalling a Mac application seems like an easy task -- just drag the icon from the Applications folder to the trash. This doesn't get rid of all of the files associated with that application, however. It might not always be necessary to get rid of all of an app's remnants, but if you're trying to reinstall an app that isn't working properly, you may need to take some extra steps first.

What to Do if Your Only Browser Isn't Working

You may find yourself in a sort of "catch-22" if the only browser on your system won't work. If the browser keeps crashing upon launch, you can't really do anything to fix it, and in order to get an alternative browser you'd need to download it -- using a browser. Here are a few things you can try to fix your current browser, and there's even an alternative way to obtain a different browser without using a browser:

Take Ownership of Old Files and Folders in Windows

Windows, or any operating system with multiple users, assigns ownership to every file. This means if you're not the owner, you can't modify that that file. The administrator account is able to access all files on the system, but Leo doesn't recommend running as administrator for security reasons. Running as a "limited" or "standard" user will significantly decrease the chance of having malware installed on your system without your knowledge.

Calibrate Your HDTV

HDTVs, by default, come set up to be put on display in a showroom. The settings are cranked up to the extreme, with vibrant and bright colors designed to catch your eye among a sea of TVs. While it may seem desirable, it doesn't provide for much of a cinematic experience and is not at all accurate to colors in the real world. This is why calibrating the TV can make it a much better experience overall.
