Hi Matthew, If you use a USB installer media then you can start up to that USB device and then under the utilities choose the disk utilitiy tool and wipe the HD by either formatting or partitioning the drive.
Then start the installation and do what you need to. -----Original Message----- From: macvisionaries@googlegroups.com [mailto:macvisionaries@googlegroups.com] On Behalf Of Matthew Dyer Sent: Wednesday, 19 July 2017 11:57 PM To: macvisionaries@googlegroups.com Subject: Question regarding mac os installer.
