I am trying to erase the hard drive on a pre 2009 iMac. After clicking on Mac HD in Disk Utility the erase button does not function.
iMac 27″, macOS 11.1
What are you going to do with the 2009 iMac?
(reuse, sell, give away, recycle)
You can not erase the hard drive that you are started up from. You need to startup from the original Install Disc 1 that came with the 2009 iMac or a bootable OS X on an external drive in order to erase the Macintosh HD.
