Have a mid 2012 Macbook pro that last week wasn't able to find the drive to boot from (just saw the folder with a question mark on booting). When I opened disk utilities from macOS utilities the disk showed errors which couldn't be repaired. At this point I attempted a restore from time machine but this couldn't get past 0.1% after 24 hours for only around 100Gb of data, this led me to believe it was the SSD that has failed.
I then formatted the drive and tried to reinstall the OS. This just got itself into a loop of failing to download Mountain Lion after 17 hours. The error was:
Reading on disk file failed, failing resume
I assumed the issue was the SSD, it's only 2 and a half years old (it was a crucial upgrade and had been functioning absolutely fine).
I have now purchased a new SSD (another Crucial but MX500). I wanted to do a direct time machine restore to the new drive right from disk utilities (which is downloaded) but this gave the error:
An error occurred while adding a recovery system to the destination disk
The time machine backup is from this exact machine but a High Sierra OS and after a little googling there seemed to be the suggestion that a bootable OS had to be in place first.
On my new SSD the download progresses fine however the download of Mountain Lion is stuck in a loop of downloading additional components. I've accessed the logs of these and I'm seeing:
Got chunk 423 of 423 Failed to verify InstallESD.dmg: hdiutil very failed Damaged resume data
The download then repeats over and over again and runs through get chunk.
I have made no other upgrades to the system other than the OS
Any ideas how I can either install the OS or restore from time machine? I know another option is creating a bootable USB ISO but I can't easily do this tonight from my work laptop and I have a feeling I'll run into the same problem
I have also run the Apple Hardware Test and ran the extended test which took around 20 minutes. This returned with "No Trouble Found"
