Apple Intelligence is now available on iPhone, iPad, and Mac!

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

When I turn on my Mac the bar only moves about a third and then a wheel appears.

There is no response from the keyboard and the permanent shift

key does not light up. The turning wheel first appeared when I tried to access Skype.


iMac 21.5″, macOS 11.7

That would indicate a failing or severely corrupt Hard Drive, if a Safe Boot doesn't help, then get an external drive to install to & see if you can still migrate your data & settings from it.


Start with this of M1 or M2 Mac...


On your Mac, choose Apple menu  > Shut Down.

Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.

Press and hold the power button on your Mac until “Loading startup options” appears.

Select a volume.

Press and hold the Shift key, then click Continue in Safe Mode.

The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.


Restart normally.


Start with this if IntelMac...


Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
