MacBook Pro keeps freezing up since installing OS X Mountain Lion

Use Time machine with an external drive - it's part of the system.

System Prefs/System/Time Machine

An external portable drive. They are widely and cheaply available - Amazon, ebuyer etc. A 1tb or 2tb should be sufficient - depends how large your computer's hard drive is, and how much info you have stored on it.

Time Machine backs everything up.

The first time takes a long time, but after that it's incremental.

You should be backing up your computer on a regular basis in case it all goes belly up in the future.

Don't wait until something happens and it's too late!

I don't know about apps, you may need to input the SN's again - I don't know.

Google for more information :-)

This is also happening to me with a mid-2010 MacBook Pro. Screen will become garbled and I can only recover by powering down the computer.

I'm having the exact same problem- late 2008 15" MBP.

It started right after installing Mountain Lion.

I have same freezing issues. I think that is after installing update 10.8.1. I got macbook pro 13 (early 2011). Its happening at least one per day. Nothing is overloaded or overheated. Just its happens anytime. I hope that next update will solve that !

I had a whole month freeze free.

This morning it happend for the second time in a week.

I've been freeze free since last weekend. I had been freeze-free for about a week before that. That was the first time it froze while I was using the machine, rather than when bringing it out of sleep.

One thing that seems to have reduced the number of freezes is taking Skype out of memory (or, it could be a coincidence).

It's disturbing to me that Apple hasn't fixed this yet (or the battery-life issue, which I also have). I saw an update this morning and I was all excited, but it turned out to only be a Java update.

Mine only seems to freeze when I'm using Google Chorme,

Obviously this is still a ridiculous situation.

I have a Macbook pro 15, bought in 2011... I kind of feel like I'm using my old Sony Vaio circa 2005 again tho...

Freeze, Freeze, Freeze!!

Hurry up with an update please Apple!!

I hate to report for me 10.8.2 fixed nothing. The crashes and freezes are not the same but still happen. 2 so far today and it's making my whole experience using this terrible. I cannot believe it's gone on this long.

The frequency of my crashes has been going down. At first it was every few days, but now it seems to be every couple weeks. No crashes since 10.8.2 yesterday, but that doesn't prove anything yet.

I've crashed more in the last two months (started with Mountain Lion) than in the five previous years.

It's a killer if you need the Mac for real-time, critical tasks. For DJs, it's a nightmare.

I am having the same problem. Thought it was just me. I am closing it daily now with the power button. Often it does not even shut down properly and constantly when I reboot it says it has recovered from a critical error. It says something about a CPU fail and lots of 00000s. I will copy and paste next time it happens.

Wish it would sort itself out, cos this is a late 2011 MBP and only had it since December. I can not kill it by using the power button everytime. Blinking nightmare.

It is also running soooooo slowly. Hardly a supercharged Apple that I was expecting for £1000!!! Been better orr with the £500 HP laptop my daughter has depsite its dreadful windows operating system. Sometimes I have to boot into the Windows 7 partition to get things done and that NEVER crashes. So I don't think it is the hardware.

I have the same problem - since updating to moutain lion my mid 2010 mac book pro will have applications like safari, mail, itunes freeze. i will then try and restart the computer and it will not restart until i force quit all the frozen applications. when i force quit all the application then the computer screen goes white - the cursor is still visible and I cannot restart the computer without pressing the power button in the top right hand corner - this issue probable occurs 2 to 3 times per day for me. the wi-fi will often stop working as well and i will get the single bar - other applications will continue to work though when safari or mail stop responding

Same here. My frequency has also gone down (but I think it's because I removed Skype from memory) and no crashes since 10.8.2.

The thing that bugs me is that there's no acknowledgement from Apple that there's even a problem. Are they attempting to fix it or are they ignoring it? Seems to me with a problem like this, you lock a bunch of developers in a room and don't let them out until they figure it out. Same for the battery life issue, although I haven't retested that since loading 10.8.2. Since they know what changes they made since the last OS, I wouldn't think it would be that hard to figure out.

One strange thing about this is that it seems to happen a little differently for each person who is having the problem. Some people crash often. Some people crash only every few days. Some people get the white screen and have to press the Power button. I don't have to do that - once I force quit each app in turn, I can restart via the menu.

80% of the freezes happen when I open the cover when I take it out of sleep - the other 20% when I'm using the machine.

If this and the battery life issue isn't fixed by 10.8.3, I'm REALLY gonna be ******. My Apple products have worked great for decades. This is the first time I'm really disappointed. My son-in-law recently bought a new MBP and has had nothing but problems with it. First the hard disk died twice then he had other problems. Since the dealer replaced the hard drive, they wouldn't switch it for a new machine (because Apple wouldn't take it back), so it had to go back to Apple for a new motherboard. Somehow I think that Apple's great success is killing the company. They can't grind out this many products and maintain quality control and their arrogance gets the better of them, which is how the maps fiasco happened.

For me, my crashes and freezes have completely stopped unless I use an external monitor! Which is something I would very much like to get back to doing when I am at work as I can be more productive.

I tried serveral monitors, just in case. I replaced my displayport to DVI connector, just in case but it's the same. If I use an external monitor I can expect at least 3-4 video lockups during the day.

If I do not use an external monitor I have no more video lockups since 10.8.2 so I'm very confused now.
