Hi all I'm having a really difficult time getting my time machine backups to work. Unfortunately something went wrong with my Mac installation - I tried to remove Windows from Bootcamp and it all went wrong. Essentially I ended up restoring my Mac because the recovery partition was badly damaged. So, I did an internet recovery which reinstalled Mavericks and then did a Time Machine restore. All was looking good - I left it overnight and it seemed to be OK. However, when it finally completed and rebooted, it got stuck on the Apple logo with a full progress bar - and I can't get it to go any further. My question is, when I do a Time Machine restore, do I need to be running the equivelent version of Mac OS when I do the restore. So, do I need to reinstall Mavericks, upgrade to El Capitan beta 6 and THEN do a Time Machine restore from the built in recovery partition? I'm at a bit of a stumbling block here. Any help much appreciated. Many thanks Alex Macbook Pro 13" Retina late 2013 Solution: Thanks to Shirasaki. If you find yourself, having done an internet recovery Time Machine restore, with a non bootable Mac (stuck at Apple logo), restore to the factory operating system, create an installer USB for the version of Mac you're trying to restore, boot onto it, and use the Time Machine recovery options there.
