Upgrade Mountain Lion

if I upgrade my SnowLeo to Mountain Lion, do I keep all my settings?

Depends on how you upgrade. If you do a an Erase and Install then, no. But if merely do a normal upgrade over your existing Snow Leopard system, then, yes you keep all your settings. If this is what you do, then be sure you repair the hard drive and permissions before you upgrade.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • HT1444 can I upgrade Mountain Lion to a Mac 10.5.8

    can I upgrade Mountain Lion to a Mac 10.5.8?

    It depends upon your Mac.  Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About this Mac" and "More Info..."  Copy and paste the information here, but omit the serial number and Hardware UUID (if present).

  • How do I (safely) upgrade Mountain Lion to Mavericks in a triple boot setup?

    When I purchased this refurbished 2011 Mac mini in late April, I wanted to set it up where I could have Mountain Lion, Snow Leopard, and Windows 7 in a triple-boot setup.  Knowing that the hybrid MBR setup limits the hard drive to three partitions, I had to get rid of the recovery partition.  Somehow I was able to make or keep both a .dmg file of the recovery partition and InstallESD.dmg and to clone these to a USB flash drive.  I eliminated the recovery partition, shrunk the Mountain Lion partition, added the Boot Camp partition, and made room for the Snow Leopard partition by further shrinking the Mountain Lion partition.  This setup has been working well for me so far.
    The discussions I'm seeing about people having trouble with the Mavericks installer wanting to create a recovery partition make me nervous.  I don't have an immediate need to upgrade to Mavericks (I use Windows 7 and Snow Leopard more than Mountain Lion), but I would like my third OS to be the most up-to-date version available, especially since Mavericks is free.  I'll be making extensive backups of all three partitions on a larger external hard disk I'm putting together tomorrow, so I'll be able to restore everything if I mess something up, but I'd rather go into the process with a fair amount of confidence that it's likely to work without too much tinkering.
    Any hints?

    The 2010 Mac mini came with Core 2 Duo processors; the 2011 Mac mini had options of Core i5 and Core i7 processors.  My Mac mini is booted into Windows 7 at the moment; the Computer window shows that I have an Intel Core i5-2520M processor running at 2.50 GHz.  This is the model that came with the discrete AMD graphics processor.  The 2011 Mac mini and 10.7 Lion were introduced at the same event; it is highly likely that later versions of 10.6 Snow Leopard included drivers for the new Mac mini in the event that Lion wasn't ready in time.  (The similarities of the 2011 Mac mini to MacBook Pro models released before Lion may also be a factor in Snow Leopard running successfully on the Mac mini.)
    I expected to have to go through extra steps to get Snow Leopard running on my Mac mini, but as long as I installed it and updated it to the latest version by using my MacBook to access the Mac mini's hard disk in Target Disk Mode, it ran just fine.  In fact, one of the first things I did with the Mac mini was the opposite:  I booted the MacBook in Target Disk Mode to see if the Mac mini could boot from the 10.6.8 installation on my MacBook's hard disk, and it worked fine.  I'm sure there are people who have had difficulties installing Snow Leopard on a 2011 Mac mini (with or without a separate Mac that officially supports Snow Leopard), but I guess I lucked out.
    The main PowerPC application that I like to run every now and then is Spaceward Ho!, a strategy game that harkens back to the days of the classic Mac OS (I've been using Macs for twenty years, back to the days of the 68040 processor).  The developer of Spaceward Ho! for the iPad has tweeted that it may release an updated version for Intel Macs, but I don't know that it will maintain the "feel" of the classic version.
    I recently decided to try the iDVD '06 that came with my MacBook on my Mac mini, and while it's not a PowerPC application, it won't run on Mavericks, so I have to keep Snow Leopard for that purpose.  Mainly it's just been a matter of preference:  Snow Leopard just feels more nimble than the more recent releases, and it gives me better control over when I save my files (or copies of them).
    Also a matter of preference:  if I'm running a Windows application, I want to be in Windows.  If I'm running a Mac application, I want to be in OS X.  I also want all of my resources devoted to the OS I'm running at the current time, not divided between both.  I may try virtualization again somewhere down the line, but right now I'm happy enough with Boot Camp.

  • Upgrade - Mountain Lion from Snow Leopard

    I have upgraded my iMac to Mountain Lion from Snow Leopard. I have a MacBook Pro running Snow Leopard; do I need to purchase this upgrade again, or will the previous purchase hold good for my Macbook Pro?

    On your Macbook Pro, assuming it is running Snow Leopard 10.6.8, you can log into the Mac App Store with the EXACT same Apple ID that you previously used to purchase Mountain Lion for the iMac.  In the Store go to your Account's "Purchased Items" list and you should see Mountain Lion listed.  Download it from there for Free onto your Macbook Pro.
    Hope this helps

  • Upgrade mountain lion, cant restore back up n iLife apps missing

    i had upgrade my macbook to mountain lion, now i cant restore my back up from my time machine and all my iLife apps and Microsoft 2008 missing. How can I get it back? 

    About ilife if you bought them from the MAS then you can redownload then again,but if no then they are in the DVD's that come with your mac.The first is the operative system but in the second one you can find the bundle applications they are the ilife applications.Just insert it and install them.
    If you loss the dvd's then contact apple and with your machine serial number probably can get a replacement.
    Hope it helps.

  • Is anybody have problem after upgrading mountain lion to 10.8.2?

    I have a macbook pro with 16 meg ram
    I have a new problem since I upgrade to mountain lion 10.8.2 :   My computer freeze  and the only way to make it works is to reboot.
    Is someone have this same problem?
    Any information about that?
    Thanks

    I'm a similar issue, but mine freezes up on almost any program and can't really see a constant reason why. I'm going to try the combo updates as sig suggested to see if that helps.

  • After upgrading mountain lion my mail is crashing during opening

    My imac 2009 has been upgrading 3 days ago to OSX 10.8.3. And since when I select Mail the window is openning and immediadtly shut down.
    I tried to re install la version of mountain lion and deled "folder" in Bibliotheue/maildata. But no resuslt.
    Apparently I am not alone with this trouble.
    Thanks to help me

    Write down all account information or take screen shots. You'll need to reenter the information later. Quit Mail. Hold down the option key while using the Finder "Go to Folder" command and type ~/Library/Containers/com.apple.mail. Move the entire container, not just the contents, to the desktop. Open Mail to see if it works. Reset all account information and test. If no change, put the container back. If Mail works properly, delete the container. You may/will lose some emails if you end up deleting the container.

  • Upgrade mountain lion to mac pro 2007

    Have older Mac Pro, early 2007. Can I uprade to Mountain LIon . The online requirement says 2008 or later

    If you are willing to endure the crushing complexity of it, there is a Hackintosh solution that allows the loading of EFI-64 work-alike software in RAM (rather than in firmware). This would allow the loading and running of 10.8 on your "too-old" Mac if this is exceptionally important to you.
    • This solution may require additional RAM, which is quite expensive for these older Macs.
    • If you have serious problems, there is no support available for such a set-up.

  • Trouble upgrading Mountain Lion

    I am trying to upgrade from Lion 10.7.5 to newest but I can't get past selecting an app. when the dialog comes up requesting it.  I see no "app" for the OS to select.

    You go to the app store and, on the first page, take a look at the right column - ML is right there:
    Click on it, pay for it, and you can download it. You don't need an app - it's an OS.

  • Slow than walk after upgrading mountain lion on my macbook pro

  • Upgrade Mountain Lion but install on an SSD

    Hi
    I am about to install an SSD drive in place of my Optical drive on my Macbook Pro.  What I want to do is run the Mavericks upgrade but install it to the new SSD instead of my current HDD.  Do you know if this is possible?  With it being so new there is very litle info about.
    Thanks
    James

    Something else to ask.... I use time machine and have a full backup.  If I do as @woodmeister50 says and install afresh on the SSD, can I then restore my apps, applications and all data from TM?
    Also, to further complicate things, I have Windows 8 installed on the HDD using bootcamp.  I want to leave this as is so if I do do a clean install, will this affect this OS?
    Q's, Q's, Q's....
