High Sierra install is frozen

My iMac 27" seems to be still running, but the screen is blank. Every once in a while I can hear the hard drive function. But, nothing else. I get no mouse pointer and my keyboard makes no difference. Does it wreck everything if I just shut down using the power button and then start up again?

Is it running OK on your machine ?

After my High Sierra install, it freeze even in safe mode !!! I do not believe things have been checked thoroughly from the software side, too many people are experiencing a freeze after their install.

Effin Right! My 2012 MBookPro froze at 43 mins remaining. After a cold reboot I am now into a complete cycle failure. Can’t even start in safe mode. Get to punch in password and Kernel version error meesages appear in Unix code and it goes to automatic shutdown/ restart

After install froze, I tried to reboot both in and out of safe mode. When I get to the log in window, I enter my password and some ”command” message appears on the left upper corner immediately followed by a blank screen and then “your computer restarted because of a problem. . . . wait or press any key to continue” in several languages and it returns back to the log in window with the same results each time. Anyone can help, please?

It is probably not necessary to delete, just follow the safari online instructions, but I read itto late. I may be wrong so maybe delete with this afts delete mode was the solution for my mid 2010 macbook pro

Sierra install AND updates only works when hardwired to the router. In my case, back to the Apple Store despite having a very strong and secure wireless connection to the www. I highly advise not “upgrading” to Sierra until Apple makes an announcement that they have finally figured out the glitch. #nobodyisperfect

Now that I agree with I just hope Apple let us know when they have sorted out this update so that it works on all their products oh and my iMac is hard wired, yet it still screwed up my machine and made me lose it for days. If this was a windows update we would be laughing our heads off me I cannot see how Apple could release a upgrade that not only did not work on all their products but totally killed the machine. If I was in charge I would have withdrawn this update until it worked properly in the first place.

Having the same problem with my iMac mid-2011 here in Sweden.

My back up is too old as I don't want to restore from 2016.

Tried installing re-installing High Sierra from a USB but the progress bar still stops at the end and I've left it for 24hrs.

Are there any solutions?

Myself I tried everything including hard reset and nothing worked the update froze and completely screwed up my iMac for days and even made it hard to restore. I will not trust another upgrade until Apple say it's all sorted and the upgrade will now install on all their products including ones with a normal hard drive and running 10.12.6. Have read nothing from Apple so assume the issue is harder to fix then they thought.

Thanks and I fear you are right.

I've now got a 27" mac which is dark on one side, fills with visible dust and now leaves me unable to work.

I'm so lucky I have a laptop and Dropbox.

Apple is no longer a company to trust.

Apple is no longer a company to trust.

Terrible thing to say but when I saw the new upgrade I thought great clicked on install and ended up losing my iMac for two days and even had a lot of problems getting it to restore the backup. I would want a statement from Apple to say that High Sierra is now safe to install before I try again. Even then I would wait until I could if it went wrong again lose my iMac for a day or two.

My OS 10.12.6

8 Memory

loads of space on hard drive (normal hard drive 500GB SATA Disk)

iMac mid 2010

But last time if froze and screwed up my iMac I restored and tried again this time it hung for hours again tried everything including hard reboot and unplugging and plugging in again leaving it for hours it still hung and getting the restore screen was a real pain.

So as the update been fixed to work I have read nothing to say it will now work on my spec iMac

I'm glad you're back up and running! :-)

Wish I could say the same. Still stuck here and my mac has loads of space too.

I'm thinking of joining Apple Developers and downloading 10.13.3 beta.

Would that make things worse or possibly solve it?

I am only back up and running after managing to restore back to 10.12.6 as for the upgrade I have not seen a reason why the upgrade completely screwed up my iMac in the first place. Unless Apple say hey the upgrade now works on any working model even ones with an inbuilt Sata hard drive and running 10.12.6 I will not chance trying to upgrade again. Always run the latest version but this time I am scared of losing my machine again and it really took a long time to get the restore screen up no idea why it must have been a real screw up on the update. If you have a backup machine and can afford to screw up your one again try 10.13.3 and lets us know how you get on.

Good luck

Well any news from Apple as anyone successfully installed High Sierra on an iMac mid 2010 with a normal beta hard drive and running 10.12.6 yet. I tried twice each time it not only froze it was very hard to restore losing my trusted iMac for a couple of days. Still not seen anything from Apple to say the latest upgrade will install faultlessly on my iMac yet so I take it they have not resolved this issue as yet. Hate Windows but Microsoft must be laughing their heads off I know my mate does when he brings his Windows laptop over and says at least I can upgrade :-)
