Stuck AFTER successful High Sierra install

Hello

I will like to disable the iCloud as I think the sync slows the computer.

I will use Google Doc instead.

Also what is that App which checks why your computer is either slow or has the beach ball rolling?

Thanks a lot,

Emmanuel

Hello

I am unsure. However at my end, I have now a speed problem on my computer.

How do I stop iCloud?

This computer does not bring me anything at all, nothing.

And yet the hard drive is not fully used and also it is not cluttered with Apps there.

Cheers,

2011 MacBook Pro here. Mine started doing this out of the blue just yesterday. After a fresh reinstall of High Sierra, like you, I turn it on today and it hangs again. How I got it working just now though is resetting the PRAM. As you press the power on button, hold Alt (Options), Command, P and R until it starts up for the second time. This only rests some small settings in the Sytem Preferences, so don’t worry about it doing anything massive. You may just have to change some settings back.

Now, whether my MacBook Pro hangs on the progress bar tomorrow when I start it up, I don’t know. I’m working through the troubleshooting list and the PRAM was the second thing to try after a fresh reinstall. After that, if the PRAM thing doesn’t work, I think I’m just gonna put it in sleep mode from there on out.

I have also had this problem too but for not that long as you did. I tried the same thing including recovery but I took my MacBook to my campus apple store and they told me that it has to do with the new OS and the Mac not being able to keep up with it, as in the RAM it has already isn't enough for it to run at all, although I was able to use Windows on Bootcamp. They said I needed to replace the ram in it with at least 8gb but at most 16gb. So I went to Best Buy and got one BUT it needed to be SoDimm (shorter memory card, 204 pins) for $90. Amazon isn't very much cheaper and it'll save you time. The cost to repair was $25.

I should tell you that if you do get a 16gb ram memory card, it needs to be 2 8gb RAM cards that are SoDimm, and they will replace the old memory cards with the new ones. If you get the 8gb RAM card, tell the repair technicians to keep one of the 2gb RAM cards in there (there are two 2gb ram cards total in your MacBook Pro that make it 4gb, I assume) so that you have a total of 10gb of RAM.

I paid $50 for the repair at my campus apple store from hourly and diagnostic. You can pay that much plus the cost of the RAM, at least $140. Or you can do it the free way: downgrade your OS to Sierra.

I had an issue with my Macbook pro late 2011. Sometimes it was stuck on boot page for hours and it wouldn't come up. But after several restart i could finally got it working! it was killing me! sometimes everything was ok but sometimes very slow boot!

I did everything from clearing the memory to deleting some boot files! nothing worked!

Then i decided to delete all my files and install a fresh version of High Sierra! before I had Yousemit!

after installing the OS! again the problem showed! this time even worse! my cpu usage was very high some times and the laptop was heating! i was going crazy!! I knew it had to do something with hardwares! The first guess was hard drive! the second guess was RAM! I changed them.... still the problem was there!!!

Finally I found the problem!!! very simple: " The BATTERY " !!!

it appears that my battery was not functioning normal and whenever I had my Laptop pluged in to power, my cpu usage was going high, so everything else was not functioning normal!!

I removed my battery and now working only with power cable! My laptop is working just fine! now looking for new battery! Problem SOLVED! hope it helps you

Thanks for this. After installing High Sierra I had the same issue. My 2010 MacBook would not load. After trying everything ( recovery mode, first aid, safe mode) My computer would not boot up. All I get is the white screen with the black Apple logo. The progress bar goes 3/4 of the way then craws. When it finishes it does ever move to the login screen. I even left there overnight still no success. I had to choose time machine from recovery mode, plug. in my externail hard drive that i saved my backups. Once I restored From the backup like you I’m back to Sierra where plan to stay. Clearly High Sierra is for the new MacBooks and iMacs. Interesting enough after reinstall Sierra is actually snapier.

I’m in the same situation now, I upgraded a week ago, and have successfully restarted a few times. I rebooted my iMac 30 minutes ago, and it appears to be stuck at the last point on the startup.

Got the same problem and shift safe mode does not work. I installed 3 times the OS and still now loading bar and apple and not getting passed this. Has your situation changed?

When the computer starts in safe mode, does it indicate this on the startup screen... mine seems to be going through the standard startup process?

Backup, I will contact Apple Support again and have them walk me through the update.

I will post again if and when everything is fixed.

i can't get mine to restart in safe mode. i get the dead corpses message that repeats in verbose mode.

What have you done now as I’m in same situation.

I save image as of HD then formatted HD and re-instal. Someone did the reinstall for me.

Is there a way to switch back to a prior OS before the High Sierra update?

Go to preferences, iCloud and turn off.
