I downloaded the "Install MacOS Sierra.app", it says there I have to move it to /Applications and then run it afterwards to update my OS on local machine.
Now, after it ran through, can I cleanly remove the installer and any related files AppCleaner offers me? Or are there some mixups with the updated OS Sierra system files?
I don't need the installer to use disk space, but of course don't want to crash my System by accidently removing something from ~/Library or wherever and then stand there with an unusable system.
Anyone already made some experiences with this?
