I have a serious problem with Time Machine. It makes backups normally but when I try to restore files from backup it crashes every time. Mac Mini 2014 middle model, I installed El Capitan 10.11.1 to external 1 T hard drive for testing purposes (I am glad I did because if this kind of problem occurred with my main install I would be furious). Time Machine backup is another 1 T external hard drive. Drive has no third party software. I tested both external hard drives with Techtool Pro and DiskWarrior, no problems found. Furthermore drives are otherwise functioning normally and Mac Mini had its motherboard replaced a few months ago so I am almost certain problem has to be in the El Capitan and not hardware. Apple discussion had a few threads about similar issue but they may not be relevant because I am not using multiple monitors unlike most people on those threads and only Time Machine crashes, Finder doesn't... I reported problem to Apple and I'm currently waiting for reply. I am curious if someone else has similar problems?
