I am having a similar problem, but not with a spinning beachball - I have a cursor I can move around, but nothing I click on works, I can't switch between programs, and Force Quit combination on the keyboard doesn't work either.
I have to restart the machine. This has happened 4 times since I installed Mountain Lion a week ago. It did not happen before.
When it has happened, I have had Safari open and been doing stuff in Safari. If video is playing, I can still hear the video and watch it - just not click on anything. I don't know if that is related or just a coincidence.
My harddrive is brand new as it was recently replaced by the Apple Store, after a HD failure.
Anyone else with this since the Mountain Lion update?
I have similar problems.
I used this upgrade to also install a new drive (Samsung SSD).
Unfortunately ML doesn't allow me todo that. USB tricks simply don't work.
So I upgraded the old HDD with ML leading to the problems described above. Beachball's, creating a new folder, not possible, access MBP through network, hmm, you can login but that is about it.
Cloned this HHD to the new SSD and hoped I could at least reinstall ML on the SSD when it was build into the MBP. Unfortunately none of these drives work.Mountain Lion can be reinstalled nor is it possible to clean install ML. I lost count but it looks like I have to reinstall the old drive again and see if that work.s
Tried to reinstall Snow Leopard but that option is blocked leaving me with a computer that cannot not be used anymore.
I have done quite a few re-installations including swapping drives over the years , never experienced so many problems with a Mac until now.
I also have had the system both freeze and random reboots. Usually it has been accompanied by severe video corruption, including flickering, and then a freeze where the mouse moves, the system still seems to be running but the screen does not update. Only a hard power button reset seems to brings it back.MacBook Pro, OS X Mountain Lion, 15", 2.2 GHz Intel Core 2 Duo
Here is a good general mac maintenance/troubleshooting article for all of you.
I'd suggest you all read it and go throught the steps that are suggested.
UPDATE ! After spending several hours , over the course of 4 days on the phone with Apple Care , they have asked me to bring the MBPro in , they want to force a reinstall , the system won't allow me to do this . I will post an update after all is said and done , thank you to everyone for your help !
I have no video screen corruption and no spinning beachball.
The system appears to be running fine and if I am watching the Olympics (for example!), the video and audio continues. But I can't switch programs, Force Quit or do anything except power down.
I have just run Disk Utility and no problems were found.
Next time it happens, I will plug in a USB keyboard and see if that works - perhaps it's bluetooth which is crashing or stopping working, since both my keyboard and trackpad are wireless.
Well, I upgraded a couple of days ago and had freezes very often.
I decided to try a clean install of Mountain Lion. So I did but I´m still suffering
from those freezes.
Yes, Safari is open all of the time and I also get reproducible freezes when accessing TimeCapsules
and copying very many files...
This system version is very disappointing at the moment ...
Yes, I uninstalled/returned Mt Lion. I told Apple I missed the days when Microsoft copied apple and not the other way around (freezing apps, slow running).
I restored from time machine that was running snow leopard, and I have my mac back without any personal data loss. No beachballs no freezing.
same here, it happened twice in 3 days, i have the macbook air 2012. Just as i was browsing the web, the whole computer just freezed, the cursor can be moved around but i cannot do anything else though.
I just left the Apple Store , they reinstalled ML from their servers in the store . Everything seems to be working well so far . If ANYBODY is having issues , remember , the software comes with 90 days of support . The whole store visit took me about 3 hours total but it was worth it , the staff was really great .
