My Mac mini won't reboot after a software update.

I started my Mac mini from the install disc and then needed to do a software upgrade. It downloaded the updates and needs to reboot. When I click to reboot it freezes on the shutdown screen. I can hard turn it off and back on but it doesn't register the restart.

I had the same issue and was able to get the update to install. I decided to check more info to see if there were more than 1 update and I found there was. I installed all the non OS updates and they went through. Then after that I did the main OS update alone and it went through without problems.

It starts just fine. I can't use iTunes because it is too old. That is when I tried to do the software update and restart. It appears to have downloaded the updates just fine but when I go to restart, it just freezes on the shutdown screen and does nothing. I've left it for hours and still nothing. If I turn it off by holding down the power button, it shuts down and I can turn it back on, but the update doesn't go into effect.


I will try resetting the SMC and NVRAM/PRAM when I get home tonight.


Thank you for your help.

It has successfully been installed. the message box staying that there are updates available pops up. I click continue to install and restart. It downloaded 5 items. Then the window pops up saying the download is complete and I need to restart to complete the install. I click on restart and the icons all go away and it's just the backdrop, like a normal shut down, but it never gets past that point.


I have just redone it again To get the complete steps for you.
