Installed Yosemite, but now the computer is restarting by itself. Anyone?

[Joeytpg]

Downloaded it on my 2010 iMac (was using Mavericks without a hitch), and the install was fine, but now, the computer get very SLOW, and after one task like updating iphoto, or cleaning the Trash bin, the computer freezes and restarts.

also I have a 1 TB drive with plenty of space and now it shows I only have 33gb left which is pretty insane.

Anyone have this issue and know how to fix it?

My 2011 24" iMac is doing the same thing as yours. When I first installed Yosemite, everything went fine, updated some apps etc and then shut the computer down for the night. Now sometimes when I log in to my account, the computer will be very slow to load and will sometimes just freeze and reboot with an error message displaying before the Apple logo appears.

My iMac has a 650GB HD with only about 200GB of it used, so HD space isn't an issue.

I have disconnected all peripherals and the issue remains.
I have tried resetting PRAM, no change.
Booted into safe mode and ran disk permission repairs, this appeared to fix the issue after boot for an hour or two.

I'm unsure where to go from here, any input would be great.

If anyone can help us, we'd be very grateful.

I discovered I had the TuneUpMyMac virus. I deleted it apparently (had to do it via Terminal).

I'm going to try repairing disk permissions via Safe Mode.

 

[Joeytpg]

Tried repairing permissions on Safe Mode, and it didn't help. Got rid of all the files from TuneUpMyMac virus (at least I think I got it all), and STILL the computer is crashing. Whenever I try to send any files to the Trash, or if I try to empty the trash, or if I try to copy files into another folder, etc etc.


very annoying.

@joeytpg try resetting the pram at least twice i.e wait until you hear the startup sound twice more after the initial startup sound, also try booting to safe mode and removing any addons listed at the bottom of system preferences or check if they have updates, they could be causing a kernel panic, the hard pram reset worked for me, no issues occurring any more.

P. S. Try running onyx in safe mode, check if you can first, and clear some old caches etc and perhaps regain some of your lost hd space, also try resetting smc

Hey candrews13, thank you for the update man, I will try these today and come back at you.

If your problem comes back let me know.

 

[Joeytpg]

well, the problems seems a bit better, as I can do more things without the machine restarting and crashing.

but still when I send something to the trash, or whenever I try to empty the trash, it crashes.

I have no add ons in system preferences, just flash player.

My early 2013 13" rMBP has froze and reset twice since installing 10.10 with no indication of the fault once it reboots, nothing in the console logs to point to the problem. Both times it happened while I was using Safari, not sure if Safari is the problem or 10.10 as I didn't use Safari with Mavericks, for now I've gone back to Chrome and the problem hasn't happened in about 24 hours.

I did a clean install of 10.10, I first wiped the drive from Linux with a live USB then installed 10.10 from a USB drive created with the createinstallmedia method.

thank you for taking the time to answer.

I'm afraid I'll have to do a clean install. I'm just afraid to loose all my stuff. I have a Time machine drive, but 2 months ago got ****ed and I haven't done andy backup for the last 2 months. I need to take the drive for a checkup. It turns on and everything, but doesn't want to mount on my desktop.

I had the problem after a clean install so I'm not sure that will help. It hasn't happened since switching back to Chrome though.

You will need a clean install.

I wouldn't bother using that time machine drive.

IMO your best bet is to get a new portable HDD and just copy your data. (Photos, music, documents, movies, emails) and no programs to this drive.

Then clean install Yosemite, install all of your apps and make sure everything is working.

Lastly move your data back. Again check everything is still working.

Once this is done make a clone of your drive or use Time Machine. (I recommend getting something like Carbon Copy Cloner or SuperDuper! over time machine). Both are fantastic utilities that create a bootable copy of your disk. This is useful if your internal HDD completely gives up.

Run Apple Hardware test on your rMBP. I had issues with my Mid 12 15", which ultimately Apple confirmed were hardware issues.
