I have access to ethernet, another macbook (about 2013-ish), a usb connector for my hard drive, a windows desktop running windows 7 ultimate, and whatever other resources a university might offer to their students in terms of tech support (However, being an electrical engineering student, I can't say I've ever been impressed by their ability to help) What else can I try to fix this? I have an osx 10.11.5 disk image on a thumb drive, but I haven't even been able to see that hardware has been connected, much less choose a boot drive. I have also tried reformatting the hard drive, again (Using a windows desktop, formatted to exFAT, but it changed nothing) While I had it in the windows desktop, I also used Seatools (the hard drive is a 1TB seagate SSD/HDD combo) to run diagnostics on the drive, but it showed no problems, from a 'Long Generic' or a 'Short Drive Self Test'. The mouse moves, but I cant't actually do anything there is nothing to click on. If I try to select a boot drive, it doesn't show the file, but it only displays the mouse on the whitish/grayish startup background. Both simply show the aforementioned file and question mark.

After two attempts (each of which didn't succeed, it seemed to download just fine, but never installed.
After which, I attempted to reinstall os X through the internet. I have been having minor issues for a couple months, so I figured I would backup and reinstall the OS to see if that would help.Īfter backing up, I booted into recovery mode to erase and reformat the hard drive. I have a late 2008, 15" macbook pro, which used to run os X 10.11.
