I recently accidentally deleted some system files of macOS and thus, reinstalled macOS Big Sur in recovery mode. I have been assured that any data will not be lost, but I am wondering what exactly comes under ‘data’.
I assume it means files, apps etc. but what about things like my preferences for various apps and changes I made in system preferences? Or, my saved passwords in safari? Does that come under ‘data’?
Also, if possible, could you provide what exactly will be lost/ changed and what will not.
Note: Before my re-install, I was running the latest version of macOS I.e 11.4
