MacOS Won't Load After HD Replacement and Formatting
Followed the guide successfully in replacing the hard drive with a new one purchased from the list provided. Was able to successfully install Snow Leopard from DVD, completed 2 SW updates, and restored data and apps from Time Machine.
I then downloaded Lion (trying to get back to Yosemite incrementally); on reboot the install progress screen appears briefly then goes to Disk Utility. Permission Verify runs and lists many issues, but Repair Permissions is grayed out. Info on the HD shows it is writable, but the partition I created is not. I believe I formatted the HD with journalling, but that option is grayed out as well.
Booted from the DVD, repaired permissions on the HD partition and verified the disk is writable, but after normal boot things are as before.
Looking for some ideas...
The IMac is a 27" EMC 2309 and the HD was on the recommended list for that unit.
No other Mac available. I erased the partition and am currently installing Snow Leopard. Once that's completed I'll go to the App Store to download and attempt to install Yosemite. If that doesn't work then I'll try the thumb drive approach. I also have an external drive -- perhaps I could create a partition there to create the installer?
Is this a good question?
