Go to the "view" menu and choose "show all devices" (VERY important that you do this).
When you get to the utilities menu, open disk utility. Now, boot to INTERNET recovery (NOT "the recovery partition): I strongly advise you NOT to erase the internal drive UNLESS you have a bootable backup! Once you do this, you're now fully backed-up and can wipe the internal drive.

#Permanent eraser for catalina install#
It is possible to use internet recovery to completely erase my SSD and install a clean copy of catalina onto the mbp, or do I have to somehow make an external boot drive on another HD to use disk utility to erase my SSD.įirst - BACK UP the ENTIRE internal drive to a cloned backup, created with either CarbonCop圜loner or SuperDuper. The mac has been taking 50 seconds to boot instead of 12 seconds when it was new, so I want to do a complete erase and installīecause I'm not trying to recover anything the above instructions are redundant but I'm also not sure of the best way to completely erase my SSD on the MB so I can do a clean install. However I'm now wanting to do a clean install on my rMBP without needing to recover anything as I have backed up my entire home folder. It may have been more complicated because I was trying to recover files. It was incredibly confusing but the take away message was that with the latest catalina it's apparently no possible to make boot drive onto a usb stick. What I thought was the right way, was not the right way and after dealing with some apple techs, who also thought I was doing it the right way but was in fact the wrong wa, I ended up having a senior advisor walked me though it which involved installing it via internet recovery onto an external drive in order to boot from that and erase the internal fusion drive, then erasing and reformatting the internal imac drive twice. I just had to do an erase and install on the gf's iMac that got stuck in a boot loop while installing.
