How do I uninstall Libav? (Issues with Homebrew & Libav)

[Amanda Young]

Last night I installed Homebrew and Libav on my brand new (3/13/17) 27” iMac. While installing, my new computer revved up and made a loud fan noise, but stopped and acted okay.

Today I had my computer freeze while using Zoom and it completely shut my computer down with a black screen and an error came up saying something like "Your computer restarted because of an error". It restarted and immediately shut down again. On the second restart it worked and I did some clean up with CleanMyMac and did an update that was waiting for Sierra and thought everything was okay. It was doing fine until I used Adobe Illustrator Creative Cloud which never is slow with maxed out RAM. But today I couldn’t even move an image around without it spinning and it took me an hour to design a simple bookmark that should have taken me 15 minutes. I couldn’t type without it spinning, I couldn’t move any element without the color wheel popping up.

So that’s when I remembered what happened last night with Terminal and installing Homebrew and Libav. I’ve figured out how to uninstall Homebrew and it says “Homebrew installed!” But I don’t know how to remove Libav and I want it off my computer. I want my computer back to what it was yesterday morning. I do have Time Machine. Can I go back to yesterday before the install and it go back to no Homebrew or Libav in the Terminal or do I have to uninstall in Terminal no matter what?

If you installed libav with brew, you should uninstall it with brew remove libav. But if you have uninstalled homebrew, this will probably won't work. But sincerely, your problem is not with libav nor brew.
