Hi there, I have a Mid 2009 MBP (MacBookPro5,3) and it's HD failed last week. No biggy, it was old, so I bought a 480 GB SSD from OWC. It arrived yesterday and I went to install OS X on it after formatting it to Mac OS Extended (Journaled) via target disk mode on my iMac. That's where I ran into trouble and need some help. Here is what I have tried to do so far: - Internet Recovery. Didn't work, my MB isn't supported. https://support.apple.com/en-us/HT202313 - I made a bootable OS X El Cap thumb drive. This was slow, but ultimately gave me an error after getting to the point in the install where the MB needed to restart. I tried this approach twice. - I made a bootable El Cap HD, thinking maybe the thumb drive was too slow or corrupt for some reason. Still didn't work, same problem as the the thumb drive. I tried this three times. - I figured maybe I had to install the ORIGINAL OS for some reason…10.5. I got my hands on the disk today and it gives me an error "Mac OS cannot be installed on this computer" - I tried the same thing using a 10.6 install disk and it loads up to the "Select a drive" portion, but won't display the SSD. Even while booted into the 10.6 install disk and in disk utility the SSD doesn't show. This is strange because is display on my iMac desktop and in disk utility when in target disk mode. - Lastly, I tried booting my iMac to the install disk and installing the OS on my MB via target disk mode, but that just gave me some terminal script on my iMac and the message that my Mac needs to shut down. Any advice??
