Macos catalina (10.15) performance issues


Disclaimer: I really don’t want to criticize this project. I love it and i think it’s what macos is lacking. I just wanna get help.

I’m on a pretty clean install of macos catalina (10.15) and i get some pretty slow performance.

When i install a package, it looks like the process hangs on “Finishing up”:

It took me about about 2 hours to install ffmpeg and it’s dependencies.

First: Is this normal? I find it pretty slow, but maybe it’s normal.

Is there something I should update or install?

Here’s my setup:
Macbook pro early 2013:

  • macos 10.15.4
  • 2,4 GHz Intel Core i7
  • 8 Go 1600 MHz DDR3


See this thread for some possible solutions: Brew install very slow, pauses for long period while executing /usr/bin/sandbox-exec in post-install
