Mountain Lion: computer freezes with videos

Just got my new MacBook Pro and updated software to Mountain Lion. Having a problem with videos, YouTube, NBC Olympic videos and the like freezing. Doesn't always occur but after a few minutes, almost everything freezes up the screen and mouse and I have to turn off the computer and re-turn it on. Any idea on how to fix this problem?

The first editions of the Mac Pro (1,1 thru 2,1) were born in 2005 with existsing 32-bit firmware and ML is becoming 64-bit only.
Not that Vista and PCs don't use 32-bit firmware and still have 64-bit kernel. If you ever tried Windows 64-bit you know the trouble we have with that on these models as well.
However, even Windows when it sees EFI and 64-bit OS expects to see Unified EFI aka EFI64 / UEFI 2.x rather than the older EFI 1.x that we have.
You can order Lion 10.7 and use that. Or you can go into the hackintosh route and treat the Mac as a PC almost and dual-boot loader to get there. But you would have to look elsewhere for support and help on other forums.

  • When upgrading to mountain lion, computer froze.

    When upgrading to mountain lion, computer freezed. Hearing beep from hard drive. What should I do?

    After doing what a brody suggested, try an SMC reset. The article covers when this is required, but doing this will not affect anything.
    Reset SMC
    If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

  • While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

    While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
    Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
    When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
    Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

    Hello John!
    Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
    It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
    This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
    or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
    An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
    Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
    Well put and understood. What I should have said was:
    1.Erase the volume
    2.Install Mountain Lion clean
    3.Confirm that Mountain Lion is functioning properly
    4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
    If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
    That makes sense and is just as I later suspected.
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
    Yes.
    This is what I did and everything works perfectly. Thank you so much once again!

  • Mountain Lion finder freezes

    Hey Apple, you must be aware of this issue so just fix the problem asap coz we are not used to Microsoft kinda freezing & crash issues. This is why we choose Apple. Mountain Lion just freezed unexpectedly and embarrasses too. I was showing Mountain Lion to a Windows friend who is proud on Windows, and it just got freeze. I had nothing to say. So please resolve it asap.

    "Its a network issue. Whenever the wifi is connected with a secure network with limited priveledges, it tries to connect and re-connect and it goen into hanging mode."
    My Finder is crashing. While working in the Finder (on Mountain Lion, MacBook Pro 13" mid 2012), searching for files using Spotlight, sometimes the Finder crashes. If I have another app open, I am able to access Force-Quit through the Apple menu, but restarting the Finder only makes it crash again, unless I turn off WiFi.

  • Can i downgrade my macbookpro (model indentify 11.1) to mountain lion, it comes with maveri

    can i downgrade my macbookpro with a last generation of proccessor intel (model indentify 11.1) to mountain lion, it comes with maveric. i want to do this because the software that i work can´t run in maverick

    I'm assuming that since you bought a new MBP that you don't have a copy of Mountain Lion? If not, I don't think you can find it on the app store anymore but you may be able to find a bootable disk elsewhere, ie. the apple support pages. If you have a copy of Mountain lion, then you should be in luck.
    First, if there are any files you want to save, you will want to copy the individual files to another drive so as to save them. You probably don't want to use time machine for this because not everything is backward compatible between the OS's.
    Once you obtain a bootable version of Mountain Lion, do this.
    Insert the recovery disc via USB or optical bay. (I think it may HAVE to be a USB stick, 4gb min)
    Shut down your computer. Wait for it to power down completely.
    Power on your computer while pressing and holding cmd + R.
    Once the page loads, Select Disk Utility.
    Erase the hard drive.
    Shut down computer.
    Reboot computer.
    After that, wait until progress bar is finished and then you should be able to install Mountain Lion.
    Good Luck!

    Your profile shows you are running 10.7.4? Is that correct? If so, you cannot download Mountain Lion without purchasing it first. Please post back with the OS version you are actually running.

  • Is OSX Mountain Lion Server Compatible with Snow Leopard

    Is Mountain Lion Server compatible with Clients running on Snow Leopard?

    We haven't had any problems with Home Directories hosted on 10.8.2 on a small number ol 10.6 clients. The only issue is that you can't use Workgroup Manager 10.8 on the 10.6 machines to allow 10.6-only apps. If you have a mixture of 10.6, 10.8 or 10.7 clients the user's prefs for things like Mail get screwy due to the different schema.

  • How do I transfer my stickies database from my lion computer to my mountain lion computer?

    How do I transfer my stickies database from my lion computer to my mountain lion computer?

    No, the Notes app.
    But I just checked and didn't see any option there. But I could swear there was an import from stickies option...
    Anyways stickies works in ML. At least it does in my system, which was updated from Lion.
    So if you don't have the stickies app you can just copy it from your Lion installation.

  • Is the Mountain Lion full compatible with the Final with Pro?

    I will like to upgrade from Snow leopard 10.6.8 to Mountain Lion. Is the Mountain Lion full compatible with the Final with Pro?

    OS X Mountain Lion is compatible with Final Cut Pro X and Final Cut Pro 7 updated to the most recent version. If you want to check that your applications are compatible, see > http://www.roaringapps.com
    Make a backup of your data before upgrading in case that Final Cut doesn't work under Mountain Lion

  • Have lion on 5 year old 20" mac desktop. tried to download and received a message mountain lion not compatible with this computer. anyone else have this problem?

    have lion 10.7.4 up graded from tiger 10.5.8. tried to download mountain lion but received a message that mountain lion is not compatible with my computer. anyone have this problem or suggestion?

    It's actually not the chip... it's the drivers for the video card. this is what my friend who does IT work said.
    "The drivers for your Mac's video card are not 64bit compatible even though the computer itself is. Mountain Lion has done away with all 32bit OS components so it only runs on full 64bit MAcs now"
    So even though I updated my video card to a newer version and my computer itself is 64bit... apple didn't create a driver for it that was 64 bit. My hardware is fine for this update and the chip can handle it. It can handle all my 64 bit programs just fine. It's apple forcing me to update and buy a new expensive computer. So much for long lasting computer... they last long but they won't be supported very long.
    Why not release a version of mountain lion that supports 32 bit graphics alongside the 64 bit? Wasn't that what grand central was going to accomplish? This is rubbish.

    If you get a message there's not enough disk space, then you need to free up some space on your hard drive by moving some data off of it. Get an external drive and start moving or deleting data until you get to at least 8 GB free space.
    If you're unsure what is taking up the space use Apple menu > about this mac > storage tab.
    What does it report your free disk space as now?

  • Mountain Lion on iMac with no SSD - why is Power Nap forcing my computer to sleep?

    I have an iMac purchased in mid-2011.  It has no SSD.  So why is it going to sleep when tasks are still running?  If I'm encoding a video in HandBrake, downloading files in Firefox or Chrome, etc...the computer goes to sleep, despite the fact that it's still doing something.  Why is this?  If my iMac is not Power Nap capable, shouldn't it use the old method for determining whether or not to go to sleep?  Why can't we choose between Power Nap and previously functioning sleep behavior?

    Maybe this will help: http://forum.serviio.org/viewtopic.php?f=5&t=7791
    I am unclear on how that will help.  It is a link to a post from a user on a non-Apple website whose first and only post is about how this problem exists.  And I assume if you're referring to the Apple Discussion thread that other post links to, you would have just posted that link instead. 
    If you intended to link to that other Apple Discussion thread, from that discussion thread, Apple told one user, "Apps need to use power assertions while engaged on activities that should not be interrupted and we are working to evangelize this." meaning that Apple realizes they haven't done a good job of letting developers know of this; and that was from October 18, 2012, nearly 3 months after Mountain Lion's release date and I believe nearly 8 months after the first developer preview.  So by Apple's own admission they haven't done a good job regarding this issue.
    However, that does explain why Mountain Lion is behaving the way it did.  Both Apple and developers dropped the ball on this given that major apps (Firefox, Chrome, etc...) still don't implement Apple's new method of power saving.
