Chosen Solution
I had to shut down my MacBook because it was frozen with a black screen (I could see the mouse arrow but nothing else & the mouse was frozen). Upon restarting it asked if I wanted to open the applications that were open when it shut down. I chose yes and it proceeded to login but nothing opened, the desktop items did not load, even the menu & dock wouldn’t load. So I shut it down again, let it completely cool off & restarted. This time when it asked to reopen the applications I chose no but now it is stuck with the error message still open & the wheel spinning. What has caused this problem & how can I resolve it without losing everything on my computer? Thanks
Do you have access to a second Mac? If you do see if you can connect your system to it in Target Disk Mode. In this case we’re trying to get to the drive to first salvage anything important. Then, Run Disk Utility from your other system on the drive to see if the disk is having a problem.
