Mac Os X Mountain Lion Download Usb
[Editor'due south note: This article is role of our series of articles on installing and upgrading to Mountain Panthera leo.]
Like Lion (OS X 10.7) before it, Mountain Lion (Os X 10.8) doesn't send on a disc—information technology'southward bachelor only as an installer app downloadable from the Mac App Store, and that installer doesn't require a bootable installation disc. But there are a expert number of reasons you might desire a bootable Mount Lion installer on an external hard drive or a thumb drive (USB stick).
For case, if yous want to install Mountain Lion on multiple Macs, a bootable install drive can exist more than user-friendly than downloading or copying the entire Mount Lion installer to each computer. Also, if your Mac is experiencing problems, a bootable install drive makes a handy emergency deejay. (Mountain Lion'south OS X Recovery characteristic, known equally Lion Recovery prior to Mountain Lion'due south release, is a big help here, just not all Macs get it—and if your Mac's drive is itself having trouble, recovery mode may not even exist available. Also, if you demand to reinstall Mountain Lion, recovery fashion requires you to download the entire 4GB+ installer over again.) Finally, if y'all need to install Mount Lion over Leopard—assuming you have the license to do and so—a bootable install drive makes it easier to do so.
Thankfully, it'south like shooting fish in a barrel to create a bootable install drive from the Mount Lion installer that you download from the Mac App Store. I bear witness y'all how, beneath.
You may have noticed that I didn't mention making a bootable install DVD. Though information technology's possible to make one, I don't recommend it these days. More and more than Macs send without a built-in optical drive; booting and installing from a DVD is very irksome; and 8GB wink drives can be found for $ten or less—there's little reason to opt for a DVD anymore. In addition, you tin can hands update a USB stick or external difficult drive each time an update to Mac OS X is released, as explained beneath; with a DVD, you have to toss the disc in the trash and first over, which is both a hassle and bad for the environs. That said, if, for whatever reason, you lot admittedly need to create a bootable install DVD, follow steps ane through 5 under "Using Deejay Utility," below, just from Step six on, follow the instructions under "To create a bootable DVD" in our commodity on making a bootable King of beasts-install drive.
(Note: As explained in our main Mount Lion-installation article, if you leave the Mountain Panthera leo installer in its default location in the Applications folder when you install OS X 10.viii, the installer will be deleted automatically after the installation finishes. And so if yous plan to use that installer on other Macs, or—in this case—to create a bootable bulldoze, be certain to copy the installer to some other bulldoze, or at least movement it out of the Applications binder, earlier yous install. If you don't, you'll have to re-download the installer from the Mac App Store before you can create a bootable install drive.)
Get the latest version of the Mountain Lion installer
Before you lot make a bootable install bulldoze, you should make sure you lot have the latest version of the Mount Lion installer. What? You didn't even realize there are unlike versions of the installer? It turns out that when you download the Mountain Lion installer from the Mac App Store, that copy of the installer installs whatever version of OS X was bachelor at the time of download. For example, if you downloaded Bone X 10.8 the day Mountain King of beasts is released, y'all downloaded the x.eight.0 installer. Which means that a bootable install drive you create from that installer will install OS X 10.eight.0.
However, unlike with the CD- and DVD-based Mac Bone Ten installers of one-time, which can never exist updated one time they're created, Apple regularly updates the Mountain Lion installer on the Mac App Shop then that it installs the latest version of Bone X 10.8. For example, when the inevitable 10.eight.i update is released, a few days later the Mac App Store will brainstorm providing an updated Mount Lion installer that installs 10.8.1 right off the bat. Using an updated installer is user-friendly, because it means that if you e'er need to re-install Mountain Lion, you lot won't accept to install 10.8.0 and then immediately install the latest big update.
Evidently, then, you want to create your bootable install drive using the latest version of the Mount King of beasts installer. However, unlike with other Mac App Store-purchased software, the Mac App Store does not update the copy of the Mount King of beasts installer app on your difficult drive. If y'all've got an older version of the installer and you lot want the latest version, you must re-download Mount Lion from the Mac App Store. (If the Mac App Shop won't let you re-download the installer, quit the Mac App Store app, relaunch information technology, and and then Pick+click the Purchases tab in the toolbar; that should testify the Download push button adjacent to Mount Lion in the Purchases list.)
Similarly, whatsoever bootable Mountain Panthera leo install drive yous create will not automatically be updated to the latest installer version. If you lot create an install drive and later download an updated version of the Mount Lion installer, updating your install drive means erasing it and repeating the procedure below.
How practise you know if you have the newest version of the Mountain Lion installer? There's a file inside the installer that indicates which version of OS 10 information technology will install, only getting to that file and viewing it is messy. The easiest arroyo is to simply expect at the Information box on the Mountain Lion page on the Mac App Store—specifically, check the date next to Updated. Then locate your downloaded copy of the Mount Panthera leo installer in the Finder, choose File -> Get Info, and look at the engagement side by side to Modified. If the Mac App Store appointment is newer than the Modified date on your copy of the installer, you demand to re-download the installer to get the latest version. (The version listed in the Mac App Shop'due south Information box is the version of OS X you'll go if you lot download the installer.)
A note on installer compatibility
The initial Mac App Store version of Mountain King of beasts will boot simply those Macs released prior to Mountain Lion's debut—Macs released subsequently Mountain Lion'southward debut will ship with a newer version of Mount Lion preinstalled. This ways that if you brand a bootable install drive right when Mountain King of beasts debuts, and then after purchase a new Mac, your install drive won't boot that Mac. Notwithstanding, every bit explained above, Apple tree regularly updates the Mount Lion installer on the Mac App Store so that it installs the latest version of OS X 10.viii. If you create a new bootable installer using the get-go major update to Mountain Lion after your Mac was released, it should be able to boot all your Macs.
There's a take hold of here, however: Recent Macs are designed to permit yous re-install the OS using Internet Recovery. And then if you purchase a new Mac post-Mount Lion, and you haven't purchased Mountain Lion for another Mac, you lot can't download the Mountain Lion installer from the Mac App Store. For Lion, I explained how to create a bootable install bulldoze for newer Macs. Once Apple starts shipping Macs with a Mount Lion version of Internet Recovery, I'll update that article to cover Mountain King of beasts.
Create the Mountain Lion install drive
At that place are a couple ways you can create a bootable install drive: using Os X's own Disk Utility or using the third-party utility Carbon Copy Cloner. The latter is easier, merely the former doesn't require yous to download third-political party software. (The developer of Lion DiskMaker volition be releasing, presently after Mountain King of beasts's debut, an update to that utility that supports Mountain Lion, giving you yet another selection.)
Note that whichever method y'all employ, yous demand a hard drive or pollex bulldoze (USB stick) at least 5GB in size (an 8GB flash drive works well), and it must be formatted with a GUID Partition Table. Follow Steps 1 through 4 in this slideshow to properly format the drive.
Using Deejay Utility You lot'll detect this utility in your Utilities folder (in /Applications/Utilities). Here are the steps for using it to create your installer bulldoze:
- Once you lot've purchased Mount Lion, discover the installer on your Mac. It'south called Install Os X Mountain Lion.app and it should take been downloaded to your main Applications folder (
/Applications). - Right-click (or Control+click) the installer, and cull Prove Bundle Contents from the resulting contextual card.
- In the folder that appears, open Contents, then open Shared Support; you'll see a disk prototype file called InstallESD.dmg.
- Launch Disk Utility.
- Drag the InstallESD.dmg disk epitome into the bottom (empty area) of Disk Utility'due south sidebar (on the left).
- In Disk Utility, select InstallESD.dmg in the sidebar, and then click the Open button in the toolbar to mount the disk image'southward volume in the Finder. The mounted volume is chosen Mac OS X Install ESD, and it also appears below InstallESD.dmg in Disk Utility.
- Select Mac Os X Install ESD in Disk Utility's sidebar, and then click the Restore button in the chief part of the window.
- Drag the Mac Bone X Install ESD icon into the Source field on the correct (if information technology isn't already there).
- Connect to your Mac the properly formatted hard drive or flash bulldoze you want to employ for your bootable Mountain Panthera leo installer.
- In Disk Utility, find this destination drive in the left-mitt sidebar and then drag information technology into the Destination field on the right. (If the destination drive has multiple partitions, just elevate the partition you lot want to use as your bootable installer volume.) Alert: The next step will erase the destination drive or partition, then make certain it doesn't contain any valuable data.
- Click Restore, and then Erase in the dialog box that appears; if prompted, enter an admin-level username and password.
The restore procedure will have roughly five to ten minutes, depending on your Mac and the speed of your drive(s).
(If you ever created a bootable Panthera leo-install drive, you may have performed the above process without mounting the InstallESD disk image. Equally of version ten.7.iv of the Panthera leo installer, and standing with the Mountain Lion installer, y'all must employ the mounted Mac OS X Install ESD volume or you'll get an mistake at the end of the restore procedure, and the newly created bootable bulldoze may not function properly.)
Using Carbon Copy Cloner Version iii.5 or later of this excellent clone-backup utility includes a special characteristic for creating a bootable install drive. (Carbon Re-create Cloner is free to try; you lot can purchase a license for $40.) One time you've downloaded information technology from the developer's website—or, if you already had information technology, once you've checked to make certain you lot've got the latest version—follow these steps:
- Find the Mountain King of beasts installer on your Mac. It's called Install Os X Mountain King of beasts.app and it should have been downloaded to your main Applications folder (
/Applications). Note that Carbon Re-create Cloner requires that the installer be located in the Applications folder on your boot drive, which means that if y'all followed my communication to movement the installer out of your Applications folder, y'all'll have to motility it dorsum, at least temporarily. - Connect to your Mac the properly formatted hard drive or flash bulldoze you desire to use for your bootable Mountain Lion installer.
- Launch Carbon Copy Cloner.
- In the Source pop-up menu (labeled Select A Source), choose Create a Mount King of beasts Installer. (This mounts the InstallESD.dmg disk image, mentioned above, and selects it as the source volume.)
- In the Destination pop-upwards menu (labeled Select A Destination), choose the drive you're using for your bootable installer.
- In the Treatment Of Data Already On The Destination pop-upward carte, choose Delete Anything That Doesn't Exist On The Source. Warning: The adjacent step will effectively erase the destination bulldoze or partition, so make sure it doesn't contain any valuable data.
- Click Clone, click Continue in the warning dialog that appears, and, when prompted, provide an administrator username and countersign.
Equally with using Deejay Utility, the process takes roughly five to ten minutes. One divergence here: Whereas using Disk Utility names your bootable drive Mac Os X Install ESD, using Carbon Copy Cloner keeps the drive's original name.
Booting from the installer bulldoze
You can now kicking any Mountain King of beasts-compatible Mac from this drive: But connect the drive to your Mac and either (if your Mac is already booted into Os X) choose your install drive in the Startup Disk pane of System Preferences or (if your Mac is currently shut down) hold down the Option cardinal at startup and choose the install drive when OS X'south Startup Manager appears.
When your Mac is booted from your install bulldoze, yous can, of course, install the Bone, but you tin can also use whatever of the Mountain Lion installer'southward special recovery and restore features—in fact, when you kick from this drive, you'll run into the same OS X Utilities screen y'all get when you boot into Os X Recovery (recovery mode). Even so, dissimilar recovery mode, your bootable installer includes the entire installer.
