I no longer have access to my iMac since 2019-03-26, the last date that it worked normally.

I restarted my iMac on 2019-03-26 and since then it does not want to display the desktop anymore.

It shows me Apple logo and the progress bar then it stops there.

I have tried everything (every started mode) including safe mode that does not work at all. I tried to Reinstall with internet, the installation finished and when restarting no change, still have Apple logo and progress bar then blocked.

The verbose mode (CMD + V) loop this message : IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

Can someone help me please I'm new to the Mac environment and in our city there is no Mac Support because this one I bought online.

Thanks for your help.

Here is the blocked screen:

Here are the features of the iMac: enter image description here

  • This is a 2011 iMac which means it's using a spinning hard drive. More than likely, that drive has failed. Try Internet Recovery so that it boots from a downloaded (in memory) image and not something off the drive. Post your results. – Allan Apr 4 at 22:23
  • I tried Internet Recovery but it's not working, after the end of the installation the same screen appear without changing. – aristos Apr 5 at 21:27
  • Then it’s definitely a hardware issue. Do you have the original install disks? If so, boot disk 2 and run diagnostics – Allan Apr 5 at 23:26
  • I have no original install disks. I tried this answer : apple.stackexchange.com/questions/267581/… but not workinh – aristos Apr 7 at 0:47
  • That post is about the MacBook Pro. What makes you believe you have a faulty GPU? – Allan Apr 7 at 20:37
