Hi guys
I have a 2015 iMac 27", lent it to a friend and... he partitioned my HD, it became full slowing down the computer no end ( that plus an array of folders scattered all over, etc, etc... ) so i tried to re-install High Sierra which i think is the OS it came with.
I shut down the computer and re started it in recovery mode - shift-alt - cmd & r keys pressed... - selected disk utility, erased the disks Macintosh HD ( 125Gb..) and the partition Disk 2 ( 1Tb point something..) assuming this would erase the partitions and present the drive as a single unit for lack of a better word..
4 attempts later i'm not any closer to managing to re-install anything.
After searching online for an answer, i tried on a friend's 2017 iMac 27" running Ventura 13.6.1 to make a bootable usb drive but it wouldn't allow me to download the OS from the appstore.
I've spent already a cvouple of days gathering info on this and trying but, to no avail.
Is my only solution to take it to an Apple tech centre to have them re-install the original OS & updates ?
Or does anyone here know how i can get out of this conundrum ?
I would REALLY appreciate it if you did
Many thanks in advance
Nuno
