How do I install Mountain Lion on a Macbook with bootcamp?
I bought Mountain Lion OS and tried to install it but it won't work since the partition map scheme on my Macbook is MBR (i assume because i installed windows with bootcamp on my HD). Is there a way to install Mountain Lion without losing my windows partition?
I have a late 2011 Macbook Pro with Win7 partition.
Mac OS X, in this case Mountain Lion can only be reinstalled using the same Apple ID it was originally installed from.

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?

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.
PS: Darn advanced editor eating bullet formatting!!

How can I install Mountain Lion on my MacBook 10.6.8
I have not been able to install Mountain Lion. I have the last MacBook that it can be installed on.
There is no explanationother than after 3 minutes, that the there has been an error in the installtion.
I don't even know where to begin!Try this:
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. -

How to install Mountain Lion on New Macbook Pro from APPS
How can I install Mountain Lion into a VM on a New Macbook Pro running YOSEMITE from APPS
I have it in my apps purchased but It tells me the system is to New to download/run it
I have tried mounting my install ESD copy but it has the same Problem
I don't have another Mac
ThanksI think the problem is that you can't install an older OS X version onto a system running a newer OS X version. So I would try the following:
1. have an external disk or create another partition on an internal drive to use for the Mountain Lion install (you might have to shrink an existing partition to make room for another)
2. Create an external bootable USB thumb drive with the Mountain Lion OS on it (do a search on the web for this - for example see http://www.macworld.com/article/1167857/how_to_make_a_bootable_mountain_lion_ins tall_drive.html
3. Reboot Yosemite and then boot from the USB thumb drive by holding down the option key
4. run the mountain lion installer and install on the new disk/partition you created in step 1 - it will also create another recovery partition from this same part of the disk
Now your Mac system will have both a Mountain Lion install as well as the Yosemite install. You won't be able to use Migration Assistant to move things from Yosemite to Mountain Lion because it will see that you're "going backwards" and won't allow you to.
Have a good backup of everything before starting in case there are problems.
Good luck... -
Hello,
I have installed mountain lion on my macbook pro ,but it made my mac very slow. Would someone please tell me how to uninstall this one and reinstall snow leopard? I tried to do it by my original CDs but macbook pro didn't let me to do it.
ThanksIt would be easier to just fix whatever is making your machine slow.
I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

I've just installed Mountain Lion on my Macbook pro and cannot now open Preview. I've partly solved the reading of PDF documents by installing Adobe Reader, but Preview is also stalling the log out process. Any suggestions how I might solve this annoying trait would be most appreciated. Many thanks.

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. -

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

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.
