how to erase iMac with high sierra
I want to do a factory rest on my iMac that has High Sierra operating system
Although following the good suggestion from @BDAqua will work
What are your plans post wiping the drive
Be aware the Full Installer of macOS 10.13 High Sierra from Apple Recovery Servers appears to have been removed
So if you plan to Wipe the Drive you are going to Require a Bootable Installer to bring the computer back to being useful again
You might do better having the Installation Media as a Bootable Installer Before wiping the drive
To perform this action will require booting from a Bootable Installer.
The Bootable Installer can Only be performed on an Apple Computer
This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.
Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can’t be used.
Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
