  • The Mountain Lion Won't Install On My 2010 MacBook Pro

    After I downloaded the Mountain Lion; it won't install because it says my hard drive is on a back up drive for the time machine. I've never used Time Machine and I only have one hard drive. I wasn't able to locate a backup file for time machine. Any suggestions on how to resolve this?

  • HT1338 When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

    When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

    There are many people suffering from this problem right now (including me). It appears to be a server issue. Just wait and try checking for updates again tomorrow.
    Some things I have heard indicate that this may be a regional problem, though what parts of the world are affected I don't know yet. A few people have been helped by deleting the following preference file (paste the path into the Go -> Go to Folder window in the Finder to locate it), though most have not:
    ~/Library/Preferences/com.apple.SoftwareUpdate.plist
    Note that if you are trying to download iTunes 10.7, that can be found here:
    http://support.apple.com/kb/DL1576
    Also, note that there is no reason to be anxious to get it, as the only thing added in iTunes 10.7 is compatibility with iOS 6, which will not be available until the 19th, and the new iPhone, which will not be available until later as well. The new iTunes that was announced is iTunes 11, which is also not yet available.

    Any OS version of 10.8.4 or later has all features that are not OS depended. The plugins are one example. You probably haven't updated all versions of Logic Pro X to the latest one.

  • How to uninstall maverick back to mountain lion?

    I have instaled maverick but have found that it does not support some programs so wish to revert back to mountin lion.  Is this possible and if it is can you give me a very basic explenation of how to do so.
    Many thanks

    Another option too for those (kind of like me) who never did the time machine.
    I just restored my computer back to Mountain Lion, and she's working perfect again, as I knew she would. E-mail popping into mailbox instantly as it should and did before the update, printer working fast as it was before update, no more freezing or glitches of any kind thankfully and finally. Here is the link that is through the Apple site to direct you on how to put your system back and get rid of Maverick's, that is assuming that is what you would like to do and also includes link for those wanting to try fixing the issue if that is your preference (most of this info is for those with mountain lion and some with the previousverisoin of OS X lion).
    If you want to keep Maverick's here is a good post on the apple discussion board to help you out:
    https://discussions.apple.com/docs/DOC-6161
    If you just want to totally get rid of it and put back what you had before, this is the short version of how to do so:
    https://discussions.apple.com/docs/DOC-3353
    NOTE: This particular link has a lot of info on what to do for different situations, it is a bit lengthy, yet still very helpful.

    I hope this helps someone, it was amazing for me and my system is working perfect again like it was, battery life is way better went from like 3 hours to like 5 (not on full charge by the way, after it sat for a while doing the online update which took a while so that's saying something alone, huge improvement). I plan to wait a while before attempting to reinstall Maverick's, long enough for them to fix the bugs.

  • Went from Mountain Lion to Yosemite on 2009 MacBook Pro.  Safari now randomly shuts down; Word doesn't work properly; iPhoto will not upload pics from iPhone; EVERYTHING is horribly slow.  How to I go back to Mountain Lion?

    Is there a way to go back to Mountain Lion after updating to Yosemite?  Yosemite has caused nothing but problems in multiple programs.  Mountain Lion ran fine.  Not sure why I even updated.  I am NOT a computer guru so instructions I have read for the many Yosemite fixes blow my mind.  Should I be taking my MacBook Pro to the Genius Bar at the nearest Apple Store (2 hours away)?  I have been a Mac user and lover for many years and am SO frustrated and disappointed in all of it right now.  Please advise on what a non-tech frustrated Mac user can do.

    Technically, you can downgrade if you have the following:
    Your computer must be elligible to run Mountain Lion. If your computer came with Mavericks or Yosemite out of the box, you can forget it.
    You need an already existing Mountain Lion installer file. If you still have that somewhere, for example in your Applications folder, or anywhere else, it's usable- note that it needs to be originally downloaded with your own Apple ID and password. If you made a Mountain Lion USB installer or DVD back then that would work too. If your Time Machine back-ups go back to the days of Mountain Lion or Lion you could check your Applications folder from inside Time Machine and restore it to your computer.
    To not have data loss you need a Time Machine back-up that goes back to when you were still running Mountain Lion. Please note that this will revert your data to exactly the date that you choose. If you installed Mavericks 2 months ago, you will loose 2 months worth of data.

  • Mavericks is slow and nothing works properly now.  How do I go back to Mountain Lion?

    I have an older iMac (purchased in the Spring of 2008).  I've updated the operating systems as new ones have come available and even installed more memory into the machine so the upgrades would continue to work.  With the latest upgrade to Mavericks I'm ready to go backwards.  Mavericks stinks.  Everything runs slowly, I get the "beach ball" all the time, and I'm constantly getting error messages.  I'm thinking maybe I just don't have enough memory to make this work properly.
    So I want to go back to Mountain Lion (which I paid for) but can't find it in my "purchased items" in the App Store and can't seem to figure it out anywhere else.  I have a backup hard drive but I haven't backed up in a LONG time so I don't want to go that route.  I'd rather just do it online.  Can anyone help?  (I'm not very tech savvy, so please keep it simple...)

    You can check to see if the Mountain Lion purchase was hidden.
    Purchases - Hiding/Unhiding
    If that doesn't work, try contacting App Store support.

  • I installed Maverick It turns off for no reasons, makes Safari a miserable experience, and more.  How can I get back to Mountain Lion?

    Maverick is a mess, well up to MS at its best.  i installed it over Mountain Lion on a base Air that initially came with Lion.  The worst is when the screen suddenly goes blank.  After a few times, i found tha tsimpy pressing the power button brought up the welcome screen which - after the password - took me back to where I was with no loss, bu tthe first time was horrible.  Then WORD for MAC started behaving strangely, with normal operations simply not working - shading to copy or cut out, for instance.  Click again and again, no shading - then suddenly it workds!  Safari has similar issues.  So too with other software downladed earlier.  simply nothing works as well as all did under Mountain Lion.
    So, I want to deep six Maverick and get back to Mountain Lion.  I assume that if I use CONTROL R I will simply reload Maverick.  Can I download Mountain Lion from the App Store and then ???  All the copying and such - a half day lost.  Is there are easier way? 
    <Edited by Host>

    It's Command-R, not Control-R. You won't lose your files or settings if you reinstall 10.9 this way. Why don't you give that a go before reverting to 10.8.

  • Mountain Lion 10.8.2 update failed on MacBook Pro

    This morning I used the Mac App Store to apply the latest Mountain Lion update along with Evernote and XCode updates. They installed, prompted me to restart and when I did I was greeted with a progress bar during startup. This gets about a quarter of the way through, then dissappears and the MacBook turns off. When I power on the laptop again, I get the progress bar again, it gets a quarter of the way through and powers off again.
    This is the first time I've had a problem with my Mac in over 2 years so I'm not too sure where to even begin diagnosing the problem.
    Any help is appreciated.

    I had a similar issue, but the update wouldn't install via the app store, it just kept saying something must be wrong with the file, so I downloaded it from Apple's website. That was a mistake. When I installed it from the downloaded file, it corrupted my machine, as it seems it has with yours.
    I tried booting into the recovery partition and running disk repar, but that told me I needed to backup and buy a new hard drive. Which I found funny since everything's been running fine up until the install (I'm on a MBP Mid-2010).
    Long story short, I ended up having to reformat and restore from a TimeMachine backup. Everything's working fine now, and disk utility is reporting no problems.
