Parameter RAM reset didn't make any difference. Tried partitioning the disk, one fails as before, the other has given two new error messages so far. WiFi is connected, it's impossible to run the installer without internet. https://files.mastodon.social/media_attachments/files/111/187/208/401/598/853/original/46a45a93ea46e634.jpeg https://files.mastodon.social/media_attachments/files/111/187/208/973/282/492/original/eb22b52d900aea99.jpeg
@f1ee7a25 Try a live Linux session from a USB key and do an analysis from there? I'm sure you can work what is going on with the disk and partitioning in a live sess.
@fcdb09df The issues feel very Mac-specific to me, I'm not sure even if I could boot it to Linux it would help. Disks all need to be in Mac format.
@f1ee7a25 @fcdb09df Do you have a spare external drive? You can boot it from a good copy of MacOS that was prepared on another machine.
@eb057e21 Good thought, I'll see if I can find a spare external disk drive and see if I can install the OS to that, reboot off it and use that to prepare a new install on the internal drive
Found an old Firewire drive at the back of a drawer - will this faulty iMac let me install Sierra on to it, since it won't let me install it on the internal drive? https://files.mastodon.social/media_attachments/files/111/190/005/729/934/778/original/dcd00fd9afb9cd83.jpeg
Will it heck as like. This iMac is cursed. I am starting to see why someone left it out for the refuse collection. https://files.mastodon.social/media_attachments/files/111/190/096/059/848/602/original/97b8f2ca217cd6d6.jpeg
