How do I factory reset my 2009 Mac without the original disk?


I have just pulled out my old 27" iMac 2009 OS X 10.6.8, I’d really like to factory reset it.

I don’t have any of the original stuff for it, I’m even using a windows keyboard and mouse. I’ve had a good search online for solutions, but I don’t have a lot of stuff for that either. I was wondering if there’s a way to restart the system and remove anything while you’re on the computer itself.

I would download the macOS 10.11 installer and create a bootable macOS USB installer:

You cannot reinstall OSX 10.6 without a retail copy of the OSX 10.6.x DVD (one with a black label).
