I hope everyone is safe.

I tried to install an Apache version using brew yesterday on my MacOS Catalina, but there were conflicts with the Apache version of the system. After some tries, I deleted files I shouldn't have deleted. Is there a way to reset or reinstall or clean the Terminal, the binaries, and the system to have the factory settings? I already searched a lot but nothing worked for me.

Thanks by advance.

  • What exactly did you delete, how exactly does the system behave "strange" now? – nohillside May 15 '20 at 9:29

The simplest "whole system repair" is to reboot to Recovery Cmd ⌘ R at boot, then just reinstall the entire OS from there.

This will repair the OS, but not remove any data or apps.

  • Thanks @Tetsujin, I'll try this now and tell you after. – g4b May 15 '20 at 9:26
