High Sierra install is frozen

I’ve been running Sierra on a mid 2010 iMac - tried to upgrade to High Sierra last night. Download went fine - install seemed to be proceeding well. However when the bar was about 95% of the way across, it just stopped. Has been this way for about 10 hours now. Computer is getting pretty warm (hot). Would you just shut it down? How do I know if something is going on still? Would you shut it down and just try to restart it? Or would you first try to restart in Safe Mode?


Not sure what is going on, but not thrilled. I do have a Time Machine backup.


Thanks,

Mark

Well I did a simple reboot and tried to do it in safe mode but I’m not sure I really ended up in safe mode but fortunately that reboot made it work! The bar looks like it was still stuck and it took about 15 more minutes and then suddenly I heard my time machine back up drive spin up for a second or two and the progress bar actually went backwards for a few seconds and then the screen started flashing rather strangely and I saw my face appear with a login box. I hit enter and it started coming to life!

Never mind Benny. It started moving finally. I guess I was too impatient. For 10 to 15 minutes after I logged in, the progress bar didn't make a move. I thought it was still frozen. Then I noticed a message "....14 minutes remaining...." and counting down. It eventually did complete the installation. But then, I think it should display some kind of message right after I restarted and logged in, just to show us that it is working again. I almost restarted again after waiting 10 minutes and saw no response. Anyway, it is working now. Thank you very much.

I have tried 3 times now but I think as a Beta tester the problem as been one of the Beta updates or so I read online. Tried again last night left it for 14 hours then I unplugged and left it for a minute replugged then left it to see if would resume. NOTHING a total time of 17 hours wasted it starts to load then just freezes before the end I have managed to get my restore to work and will give up trying to update, this is rubbish apple

"Unfortunately, when you install 10.13.0 it automatically renders much Apple software to be incompatible with 10.12.6"


You seems to be right as a Beta tester I am running 10.12.6 and after three attempts the new software just freezes even after being left for hours, last attempt 17 hours !


So I now take it current Beta testers with 10.12.6 cannot upgrade to the new software, well thank you apple for that no more updates RUBBISH

I kept shutting down and kemp trying to start up in the restore mode the software update also seemed to screw up this as well but eventually I managed to get the restore mode up and restored back to 10.12.6. The restore mode took a little time to load so as long as you have a backup you should with patience be able to restore. Tried the high update twice and in my experience it will not load on 10.12.6 even after leaving for a very long period apple as screwed it up.

Hope you restore your back to life, good luck

From what I have read if you have been running 10.12.6 (like Beta testers) then the new upgrade will not load and will just freeze so do not try until apple respond and say the problem as been fixed. To be honest after the freeze I could not get into the safe mode and it took a few tries to get my iMac to startup in the restore mode so I could restore. Back on 10.12.6 so after trying to upgrade twice and losing the use of my iMac for a couple of days I will not try again until apple says it is now safe for all to update. I have not read any response from apple on this so I can only presume they are working on a fix then I may try again, funny this is as a Beta tester when I saw there is an upgrade ready to install I just clicked on restart as normal. Couple of days later and hours of wasted time I had to restore to get use back again, thanks apple

I had that took awhile to manage to get my iMac to start in restore mode just keep trying and I hope you have a restorable backup or you could be screwed. Have not seen anything from apple to explain why their new upgrade keeps bricking machines how could they have screwed up so much. You would have thought they would have warned people that the new upgrade will only go on top of versions up to and if you have version 10.12.6 then the upgrade is not for you.

MississippiMills keep trying and hopefully your get the restore screen again I can tell you when I saw that my heart fluttered, in the meantime thank apple for wasting so much time. Tell you what after releasing the right combination it took some time for the restore appeared for the first time.

Good luck

Dewey are you saying you started the upgrade on the 17th and still not recovered your machine yet thats terrible I lost a couple of days but then stupidly I tried the update twice, what a fool. What I did with mine was unplug and leave for 15 seconds then plug in hold the combination to start in recovery mode turn on weight till the useless hang page appeared then released the keys and wait for a few minutes and eventually it started in recover mode.

On top of my screen right now says "Upgrade to macOS Sierra" oh yes you bet I will click install again and lose everything for another day or two, no elfin way. Until apple say the upgrade will work on 10.12.6 I will NOT be upgrading again, thanks apple and why no response.

Good luck Dewey

I selected to download High Sierra and on restart the progress bar stayed stuck a half way for 4 hours. Restarting in safe mode did not work. I took the mac to the genius bar, they could not get the machine to start in safe mode or diagnose the problem, the diagnostics indicated the hardware was ok. The tech wiped the hard drive and I restored my files from my cloud source. This is the second time this has happened on a software update. A genius bar appointment to wipe the hard drive is not a sustainable solution. I am currently running Sierra 10.12.6 on an early 2015 mac book.

Well as said I was and still running (after lucky enough to restore) 10.12.6 and lost my iMac for a couple of days after trying to upgrade. The issue is 10.12.6 and from what I have read its an hard drive issue 10.12.6 changes the way the hard drive stores files sadly the High upgrade does the same but will ONLY go on older versions not 10.12.6.

Still no news from apple as to why we cannot update the software. Read somewhere there is a solution that entails making a boot disk then formatting the drive installing High and then try and get you old files back, cheers apple but to much my me to try.

Why no response from apple saying why this is happening even that we can never upgrade again, BUT NOTHING from apple at all.

Got 10.12.6 then update at your own peril

good luck
