Enabling Hot Corners on a Mac

So you got gotten D=

Here’s how you ensure you can quickly lock your mac to prevent folks from giving your computer a cronjob. Just enable hot corners and ensure that it requires a password to unlock. Here’s how:

Step 1: Enable hotcorners

  1. Go into your system preferences (the apple icon in the top left corner of the screen)
  2. Search for “Hot corners” (or just hot will probably do) which should light up “Desktop & Screensaver” stuff like this:

  3. If you encounter trouble modifying any of the options, you may need to unlock your settings. Look in the bottom left corner of the settings window and click the lock. You should be prompted to enter your password. Authoritate yer computer and rock on!

Ensure that when it turns on, that it requires a password to unlock. This is a great way to protect yourself against shenanigans, and a good step to help make sure you aren’t the victim of a USBDriveby D=
