  • How do you install mountain lion on all your macs in the household using one 20 dollar license?

    how do you install mountain lion on all your macs in the houshold with the same license (you only pay 20 bucks for all your macs) is that right?

    As long as they're all logged into the Mac App store with the same Apple ID, you can re-download the installer to all the Macs.
    Or you can save a copy of the installer file before you run it and use that to update the other Macs. The ML installer file will appear in your Applications folder when it's done downloading. Copy it to another location (don't move it).
    If you don't copy it before you upgrade, it will disappear when ML is finished installing.

  • How do I Install Mountain Lion on a Mac with 2 Drives

    Good day ALL,
    I am upgrading my Mac mini to add a second hard drive (solid state).  After the HD install is complete I plan to re-install Mountain Lion and transfer my Applications, Files, etc from my backup.  I am very comfortable with installing Mountian Lion on the solid state drive and making it the bootbale drive, my questions are:
    1.  It is a 120G soloid state hard drive, so I only plan to use it for the OSX system, Library and Applications.  Should I include other files?
    2.  I plan to use my 750G SATA drive for the Users.  How do I set up the User Folder archive on this drive?  Do I just move it?
    3.  Then how do I ensure the User Folder on my backup, gets retored on the right drive?
    Thanks

    Regarding 1:
    $ cd /Users. sudo ditto myname /Volumes/TimeMachine/myname  copies everything in $HOME to non-TM backup.
    Ensured latest SSD firmware up to date.
    Clean install of ML to SSD from 8GB USB stick created by Lion Diskmaker.
    $ cd /Users. sudo ditto /Volumes/TimeMachine/myname myname (see part 2 for /Users on another drive)
    Added latest Xcode and command-line tools. Added VirtualBox 4.1.20. Put the 65GB VirtualBoxVMs folder on the second drive. Edited the ~/Library/Virtualbox/VirtualBox.xml file for the new mount points. Beware that many SSD (including Vertex) warn not to exceed 50% drive capacity or they will invoke slower drive controller algorithm. After some clean-up and re-arrangement, I have 98GB free on this SSD. It sings.
    Files that are heavily accessed/shared by users would be consideration for the SSD
    Regarding 2:
    If you have sufficient external storage, back-up your pre-ML /Users either with ditto as I did, or with TM, somewhere other than the 750GB drive.
    Use DiskUtility and repartition the 750 as one (or more) GUID HFS+Journaled partitions depending on planned usage.
    Reverse the back-up to put your user(s) on the 750GB drive
    In System Preferences > Users & Groups, unlock, then right mouse button click on individual user names. Advanced options ... will appear. For Home directory, Choose ... the particular mount point for individual user accounts now on the 750GB drive. Done.
    Regarding 3:
    Because you have moved individual user accounts from the internal drive where your last TM backup occurred before ML installation, TimeMachine will not understand (as far as I know), the new /Volumes/750GB/User/you home directory location that you just changed in #2. Another reason I used ditto(1).
    If you do not want Spotlight to index that 750GB drive, you need to inform Spotlight Preferences > Privacy to exclude the drive.
    Hope this helps.

  • How do I install Mountain Lion on my Mac?

    How do I get the App Store on my Mac so I can download Mountain Lion?

    Actually, More than anything I need to get the App Store BACK onto my computer. I know how to get Mountain Lion from there.

  • Hi, I have a late 2008 iMac with a new hard drive. How do I install Mountain Lion from my bootable USB flash drive.

    How do I install Mountain Lion to a new hard drive without having the recovery partition on it.
    I have the USB flash drive with software on it but when I switch my Mac on all I have is a white screen & a flashing question mark.
    ATB,
    Steve.

    Did you use LionDiskMaker or DiskMaker X?
    Boot the machine with the option key down until you see your bootable USB stick.  Select the latter, and reboot.
    When the installer boots up, you will first need to choose Utilities and Disk Utility. Select the target HD device name and then the partition tab. Select 1 partition, name it Macintosh HD. Format is Mac OS Extended, and option is GUID. Apply. Exit Disk Utility and return to the installer, which will now show your newly partitioned HD as available for install.
    When OS X is installed and all updates applied, press shift+command+U and run disk utility again. Verify/repair permissions and verify the boot disk.

  • How do I install Mountain Lion on a thumb drive?

    How do I install Mountain Lion on a thumb drive when my computer is running Mavericks? I downloaded the Mountain Lion installer, but when I attempt to run it I get a message that says "You cannot install OS X 10.8 on this computer." I don't want to install it on the computer, I want to install it on the thumb drive—but it won't give me a choice of drives.
    The reason I want to do this is I want to be able to boot my iMac into Mountain Lion in order to test a hardware/software combination I suspect might be incompatible with Mavericks.
    (Note: there are plenty of instructions online for how to create a bootable thumb drive with the Mountain Lion installer, but that's not what I want. I want to install ML on the thumb drive itself.)

    Sure you have a proper installer application. When I start it I get:
    Clicking on Continue, then accepting the licensing stuff, gets me to:
    If you click on Show All Disks, then all mounted disks will be presented including your flash drive.
    Now the above is a Mavericks installer, but it's the same for Mountain Lion.

  • HT1338 how do i install mountain lion

    how do i install mountain lion the system will not allow me to "app it" as the Mac OS is older than 10.6

    If your Mac is compatible, the upgrade path for you would be to purchase Snow Leopard from the Apple Store: http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
    After installing that, you would run Software Update to bring it up to 10.6.8.
    Then, you'd access the App Store from Snow Leopard and purchase Mountain Lion.

  • How do I install mountain lion over maverick

    how do I install mountain lion over maverick

    Before the install
    Ensure your data (at least all Home folders) is backed up before you install. Hard disks can fail at any time so it is important to regularly backup to an external disk with Time Machine or a third party alternative. Inexperienced users should follow Apple's install advice but experienced users may prefer to do a clean install.
    OS numbers and names
    OS X 10.4.x - Tiger
    OS X 10.5.x - Leopard
    OS X 10.6.x - Snow Leopard
    OS X 10.7.x - Lion
    OS X 10.8.x - Mountain Lion

    Upgrade to Leopard
    Those wishing to upgrade to Leopard should be aware that install disks can be expensive. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
    Upgrade beyond Leopard
    OSs beyond OS X 10.5.8 require an Intel processor. If in doubt click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

  • Brand new Mac, had to erase drive through disk utility as time machine back up failed. Now disk utility only has the option to install Mountain Lion which my Mac won't allow. Anyone any ideas as my Mac won't load anything up but disc utility!

    Brand new Mac, had to erase drive through disk utility as time machine back up failed on initial setup, USB cable popped out Now can only access disk utility as won't load to log in screen. The only has the option in disc utility is to re-install Mountain Lion which my Mac won't allow or loading another time machine back up but after an hour of it processing, that didn't resolve the issue either! The time machine back up is the latest back up of my Mac Book Pro which was using OS X Maverix. I'm guessing I'm going to have to take my Mac to the store but that would be a hassle so does anyone have any ideas?

    Follow this guide using another Mac.
    Insert your newly created Mavericks USB into you Mac, press the power button and then hold down 'option,' until it gives you an option to boot from the USB. You will then be able to erase the internal disk with Disk Utility and reinstall Mavericks straight after.
    After that you should be able to use Migration Assistant to restore your applications and user data.

  • Instal Mountain Lion on a mac book pro from october of 2008

    Is it advisable to install mountain lion on my mac book pro, bought in october of 2008 (first generation aluminum body), or will it not work/work very slow?
    An search on the internet gives different outcomes..
    thank you!

    The date of purchase is not a reliable indicator that your Mac Book Pro meets the requirements for Mountain Lion.
    Check out exact technical informaitons for supported models here:
    http://www.apple.com/osx/specs/
    Even if your computer meets the requirements for Mountain Lion doesn't necessarily mean it's advisable to do so. For example, if you rely on applications that are not compatible with Mountain Lion.

  • HT4854 How can I load Mountain Lion to multiple Macs

    How can I load Mountain Lion to multiple Macs without downloading the huge 4Gb file to each machine?

    I've never done that, but I don't see why it wouldn't. There is no verification or authentication keys in the installer.
    If you need 20+ licenses*, then you might take a look at the volume licensing: http://www.apple.com/mac/volume-licensing/
    It describes the same process I described.
    * I think 20 is the minimum. Not sure, though.

  • Installed Mountain lion on my Mac book pro. Now My IRONKEY flash drive is not launching.

    Installed Mountain lion on my Mac book pro late 2011. After that my IRONKEY flash drive is not launching. Before it was launching OK.The flash drive has updated software.

    You have some other problem with your boot drive that has corrupted data backed up to the TimeMacine drive.
    My advice is to boot into each operating system and manually backup just your Users files each to separate regular external drives (no Timemachine or backup software) and disconnect.
    Make a note of any serial numbers, emails, address book contacts, export bookmarks etc. that isn't typically in your users folders data.
    You might be able to Winclone 3 the Windows as a whole thing as it's appearing not to have issues but it's your MacintoshHD partition that is so that will have to be rebuilt from scratch.
    Most commonly used backup methods
    If your OS X parititon doesn't boot, you can use this to recover files.
    Create a data recovery/undelete external boot drive
    Without any further detail about your machine I can't advise specifically what to do, but it involves using Disk Utility to Zero Erase (move slider one spot to the right or in 10.6 using Security Option) the ENTIRE boot drive and reformatting, then installing OSX fresh and then setting up BootCamp again.
    If you wish to switch your boot drive for something better, this is a good time to do this.
    Install/upgrade RAM or storage drive in Mac's
    If your machine is capable of Internet Recovery, then use that, then upgrade.
    If your machine came with 10.6 or earlier, then use the 10.6 install disks and work up from there.
    Erase, formatting, OS X installs on Mac's

    Open the Mac App Store on the other Mac and in the Quick Links sign into your account. See if the Mountain Lion purchase is among hidden apps in the iCloud area of your account info.
