Stuck on Start up Apple
I recently updated to Sierra and have had endless troubles with programms hanging and constantly shutting down.
Last week my macbook gave up totally and now when switched on all I see is the Apple logo with the progress bar in full dark grey.
I have been through step for step safe mode, fsck - fy mode, tried the Control +T mode to NO avail.
Safe mode gave me an all clear that device is ok.
Today i got diskOs2: I/O error. :-(
does anyone have any advice? I have very important information on the harddrive let alone all the apps i have installed for work.
I was unable to back up from time machine as the computer is blocked by an administrator.
Disk utility also gave an all clear on all hardware.
