upgrade from Sierra 10.12.6 (16G2136) to High Sierra could not complete
Hello,
I have a macbook pro 13-inch, early 2011 and I am trying to upgrade my Sierra 10.12.6 (16G2136) to High Sierra but the upgrade could not complete because it says "file system verify or repair failed". I tried restarting several times but nothing worked and I could not just cancel the upgrade and return to the old OS because everytime I restart, the upgrade window appears. After some time I had to restore from Time Machine backup to be able to use my macbook again with the old Sierra OS.
I wonder if it is worth upgrading to High Sierra. I have a few movies on itunes that after upgrading from mountain lion to sierra I was not able to open them anymore.
I hope someone could help, thank you!
