Hi guys, need your help My macBook Air 2014 works well with Yosemite and yesterday I tried to update it to last EL Capitan. It freeze at last 2-5mm of horisontal indicator. I tried to reboot after 3 hours waiting, but it did not help. Then I tried to reinstall MacOS from recovery mode without formatting the disk. Same thing, on last step it freeze. Also tried boot in single user mode and "fsck -fy" twice. And tried "first aid" disk utility. Did not help too. Screenshot from verbose mode: http://i.imgur.com/c1LjiSr.jpg I know that clean install would be better but I need to save a data from macbook before.
