My Macbook Pro keeps freezing. Help!

Hi, I have a macbook pro mid 2010 model running OS X Lion 10.7.4 with 8GB of RAM (3rd party upgrade), 128 SSD. Up until about 3 weeks ago everything was running fine. Then one day the mac just froze and it's been doing it ever since on an irregular basis. Some days it will happen 10 times in one day, then it won't happen for 3 days.


Symptoms:

- The mac will freeze completely, no mouse, trackpad or keyboard input, if itunes is playing a song it will just hang and repeat the last 1/2 second of the song like a broken record. The only way out of this state is to do a hard reset.

- Occasionally I get some screen on startup that says I must hold down the power button to restart. It says this in about 5 different languages.

- Occasionally starting up the mac gets to the grey screen then doesn't move. Again I must do a hard reset.


Attempted Fixes:

- Booting up in safe mode does not fix the issue. It sometimes freezes in safe mode, or gets stuck on the grey screen.

- Apple Hardware Test - No issues found after running 3 times in extended mode.

- Verified/Repaired disks - Problem remains.

- Restored from a time machine backup. I didn't expect this to fix it, and it didn't.


If anyone has any ideas on what could be causing the issue, or any way to figure it out I am all ears.


Thanks,

Graham

After upgrading to 10.8.2 I became a member of this special club. Has rendered my MBP practically useless. Can't leave my track pad alone for more then 40 seconds before it freezes or my keyboard gets a mind of its own.

Apple next time you do an update make sure you check it out at all machines.

Thanks for the advice of getting the graphics card checked. Hopefully it works.

Have the same problem here. MBP i7 2.7, 16gb ram, original hd. OS 10.8.2.

I did something that helped me a lot and thought i shared it with you. I noticed that after a freeze my desktop icons had no preview image, just the files and the type.


I did a backup to an external hard disk to both my desktop files and my files in documents and video folders. So MBP is almost empty (apart from FCPx files). Also deleted any apps i did not use and had download for fun. Desktop has no files. Did a repair disc permissions.

NO FREEZES since.

So I'm guessing that it might be a FINDER issue.


Hope this helps someone.

Same problem here.

Everything was working very well until the install of a Crucial 240 Gb SSD. Now after some period on sleep (or with no activity) the computer freezes. No spinwheel, only freezes and I need to turn off and turn on to use it again.

Does anyone know if theres a firmware update to solve it?

My share of problems are beginning to resurface! After the firmware update it worked fine for a while. Now when I use it, it continues to work fine untill i reboot! Thats when it will show a gray progress bar which would halt abruptly shutting down the machine. No go form there on. Running disk utility from an installer disk would reveal that the drive has gone corrupt. Verify Disk would report some kind of a problem that can only be solved my formatting the drive and restoring it from a tm backup. the repair option fails to repair the drive.

I think most folks on this forum would be amazed at how well Snow Leopard works if they were to reinstall clean with 10.6. Lion was flaky and ML is crap, they never even fixed Lion before releasing ML. You lose iCloud integration with SL (I can live without it) and some of the bells and whistles but man is it ever fast and stable, try it and you will see how OSX is meant to be. I rolled back to it off of ML months ago and it hasnt spun or froze or even glitched even once.

Hi


Things got even worse before Apple did anything!!


Apple initially refused to exchange the machine telling me if it went wrong one more time then they would replace it, despite the long list of faults already. A few days later the same problem (never went away) got worse - I took it back in and they finally agreed to order a replacement. In the meantime they told me to keep using the machine till the replacement arrived. I think 3 days later the I was working on the mac and then it went bang (not very loud) - the screen went black and all function died. That was the end of that cursed/elegantly beautiful machine. I honestly think the problem is with the venting system - I think these machines can't cool down but I'm no expert. Interesting that the newer machines have air vents in the body casing.


To be fair Apple were true to their word (albeit grudgingly) & a replacement arrived - though it just doesn't have the same beauty - firstly it's 15in not 17, you have to plug in an external DVD drive! I'm not impressed with the retina screen - no big difference for the average user.


Now trying to get my apple care protection plan money refunded was whole new dilemma - you won't believe what I went through!


Good luck with your machine. In my humble opinion if it's under warranty take it back!
