Unable to Download Mac Os X Mavericks
Mavericks (OS Ten 10.9) doesn't transport on a disc. Instead, information technology's available only as an installer app downloadable from the Mac App Store, and that installer doesn't crave a bootable installation disc. But in that location are a good number of reasons you might want a bootable Mavericks installer on an external difficult drive or a thumb drive (USB stick).
For case, if you want to install Mavericks on multiple Macs, using a bootable install drive tin can exist more convenient than downloading or copying the entire installer to each reckoner. Likewise, if your Mac is experiencing problems, a bootable install drive makes a handy emergency deejay. (The OS Ten Recovery feature is a large assist here, but not all Macs take it—and if your Mac's drive is itself having trouble, recovery style may not even be bachelor. Also, if you need to reinstall Mavericks, recovery style requires you to download the unabridged five.3GB installer once more.) Finally, if you need to install Mavericks over Leopard—assuming you take the license to exercise and so—a bootable install bulldoze makes that process easier.
Thankfully, it's not too difficult to create a bootable install bulldoze from the Mavericks installer. I prove you how, beneath.
If your Mac came preinstalled with Mavericks
If you ain Mavericks just because you bought a Mac that shipped with Mavericks preinstalled—in other words, you never purchased the Bone from the Mac App Store—use our instructions for creating a bootable Mavericks install drive for newer Macs , instead of the instructions here.
Go the latest version of the Mavericks installer
Before yous brand a bootable install drive, yous should brand sure you take the latest version of the Mavericks installer. What? You didn't even realize that at that place are unlike versions of the installer? It turns out that when yous download an OS Ten installer from the Mac App Store, that copy of the installer contains whatever version of Os X was bachelor at the time of download. For example, if you downloaded OS Ten 10.9 on the 24-hour interval Mavericks was released, you lot downloaded the 10.9.0 installer. A bootable install drive yous create from that installer will install OS Ten 10.9.0.
Notwithstanding, Apple tree regularly updates the Os Ten installers information technology makes available for download from the Mac App Shop. For example, when the inevitable 10.9.one update is released, a few days subsequently the Mac App Store will begin providing an updated Mavericks installer that installs x.ix.one right off the bat. Using the latest installer for your bootable install drive is convenient, considering it ways that if you ever need to reinstall Mavericks, you won't have to install 10.9.0 and so immediately install the latest big update.
Obviously, then, yous want to create your bootable install drive using the latest version of the Mavericks installer. Even so, different with other Mac App Store-purchased software, the Mac App Store does not update the copy of the Mavericks installer app sitting on your hard drive. If you've got an older version of the installer and you want the latest version, y'all must delete your electric current re-create of the installer and and then redownload the Mavericks installer from the Mac App Store. (If the Mac App Store won't permit you redownload the installer, quit the Mac App Store app, relaunch it, and so Option+click the Purchases tab in the toolbar; that should prove the Download push button next to Mavericks in the Purchases list.)
Similarly, whatever bootable Mavericks install bulldoze you create volition not be updated to the latest installer version automatically. So if yous create an install drive and afterwards download an updated version of the Mavericks installer, you lot'll desire to erase that install drive and recreate it using the new installer.
How practise you know if y'all accept the newest version of the Mavericks installer? The easiest approach is to look at the Data box on the Mavericks page on the Mac App Store—specifically, check the appointment next to Updated (or Released, equally the instance may be immediately after the initial release). Then locate your downloaded copy of the Mavericks installer in the Finder, choose File -> Go Info, and look at the date side by side to Modified. If the Mac App Shop appointment is newer than the Modified date on your copy of the installer, you demand to redownload 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 get if you download the latest installer.)
Note: As I explained in our main Mavericks-installation article, if yous leave the Mavericks installer in its default location in the Applications folder when yous install OS X 10.9, the installer will be deleted automatically afterwards the installation finishes. So if you plan to utilise that installer on other Macs, or—in this instance—to create a bootable bulldoze, be sure to re-create the installer to some other drive, or at least move it out of the Applications folder, before yous install. If y'all don't, you lot'll have to redownload the installer from the Mac App Store before you can create a bootable install drive.
A note on installer compatibility
The initial Mac App Shop version of Mavericks will kicking only those Macs released prior to Mavericks'due south debut; Macs released after Mavericks'south debut ship with a newer version of Bone 10 x.9 preinstalled. This means that if you made a bootable install drive immediately later on Mavericks was released, and then later bought a new Mac, your install drive won't boot that Mac (though it volition boot any older Macs you own).
However, every bit explained above, Apple regularly updates the OS X installer on the Mac App Store so that it installs the latest version of OS 10 x.9. If y'all create a new bootable installer using the first major update to Mavericks afterwards your Mac was released, that drive should exist able to boot all your Macs.
What about an optical disc? You may take noticed that I didn't mention making a bootable install disc (DVD or CD). Though you lot can practice information technology, I don't recommend it. More and more Macs ship without a built-in optical bulldoze; booting and installing from a DVD is very ho-hum; and 8GB flash drives tin be constitute for $ten or less. All of this means that in that location's piddling reason to opt for a DVD anymore. In addition, whenever an update to OS Ten is released, you tin easily erase your bootable USB stick or external hard drive and update it to contain the latest OS Ten installer; with a DVD, you have to toss the disc in the trash and first over, which is both a hassle and bad for the environment.
All that said, if you're absolutely convinced that you need an optical disc, Thomas Make explains how to create a Mavericks recovery CD. The resulting disc won't contain the full installer; rather, it'southward a CD version of OS X Recovery. This means that when you install Mavericks using the disc, the installer needs to download roughly 5GB of installer information on the fly—which means that installation will be even slower.
Create the Mavericks install drive: The options
There are three ways yous can create a bootable OS X install drive: using a new feature, called createinstallmedia, built into the Mavericks installer itself; using Deejay Utility; or using the third-party utility DiskMaker X, which, despite its name, likewise works nether Mavericks. (For OS Ten x.seven and 10.8, you as well had the option of using the 3rd-party utility Carbon Re-create Cloner. Still, because of changes in Mavericks, the programmer of Carbon Copy Cloner has removed this feature. I'll update this article if Carbon Copy Cloner becomes an selection once more.)
Using the new Mavericks feature for creating a bootable drive, createinstallmedia, is the easiest method, and information technology's the one that I recommend most people try first. However, it doesn't work nether Snow Leopard—simply King of beasts or later. DiskMaker X is the next-easiest method, simply I've experienced the occasional failure with information technology. (DiskMaker 10 also doesn't work under Snow Leopard.) The Disk Utility method is very reliable, and information technology works under Snow Leopard, Panthera leo, Mountain Panthera leo, and Mavericks.
Annotation: There'due south one significant difference between the iii methods that you should be enlightened of. Based on my testing, if the drive onto which you're installing Mavericks doesn't already take a Recovery Hard disk drive sectionalization, a bootable installer bulldoze fabricated using createinstallmedia or DiskMaker 10 (which uses createinstallmedia under the hood) can create that partition during the 10.9-install process. A bootable Mavericks installer drive made using the Disk Utility procedure will not. You can decide whether or not your Mac has a Recovery Hard disk division using the instructions in our article on recovery manner.
Whichever method you use, yous need a Mac-formatted drive (a difficult drive, solid-state drive [SSD], pollex drive, or USB stick) that's big plenty to concord the installer and all its information—I recommend at least an 8GB wink bulldoze, though anything larger than roughly 5.5GB should work. That bulldoze must also exist formatted with a GUID Partition Table. Follow this tutorial to properly format the drive.
Hidden inside the Mavericks installer is a Unix program called createinstallmedia, provided by Apple for creating a bootable Mavericks installer. If yous're comfy using Last, it'south a relatively elementary tool to employ. The program assumes your account has ambassador privileges.
Note: This method does non work in Snow Leopard. It works only in Lion, Mountain Lion, or Mavericks. (The resulting installer drive will allow you install Mavericks over Snowfall Leopard, just you lot tin't create the installer drive while booted into Snow Leopard.) If you need to create a Mavericks install drive while booted into Snow Leopard, yous should use the Deejay Utility instructions, below.
- Download the Mavericks installer from the Mac App Store and make sure it's in your master Applications folder. (This means that if yous followed my advice to move the installer out of your Applications folder, y'all'll take to move it dorsum, at to the lowest degree temporarily. The Final control I'g using here assumes the installer is in its default location.)
- Connect to your Mac a properly formatted 8GB (or larger) drive. Rename the drive to
Untitled. (The Concluding command used here assumes the drive is named Untitled.) - Select the text of this Final command and copy information technology:
sudo /Applications/Install Os 10 Mavericks.app/Contents/Resource/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install Os 10 Mavericks.app --nointeraction
- Launch Last (in /Applications/Utilities).
- Paste the copied control into Final and press Return. Warning: This stride will erase the destination bulldoze or partitioning, and then make sure it doesn't comprise any valuable data.
- Enter your admin-level business relationship countersign when prompted.
- The Terminal window displays the progress of the process, in a very Terminal sort of manner, by displaying a textual representation of a progress bar: Erasing Disk: 0%… x%…20%… and so on. The program so tells you it's copying the installer files, making the disk bootable, and copying boot files. Await until yous see the text Copy Complete. Done. (run across the screenshot below), which could accept as long equally xx or 30 minutes, depending on how fast your Mac tin can copy information to your destination drive.
You at present take a bootable Mavericks-install bulldoze. If y'all're curious almost createinstallmedia, blazon or paste the following command in Concluding and press Return:
/Applications/Install Bone X Mavericks.app/Contents/Resources/createinstallmedia
The resulting text output shows you the (brief) instructions for using createinstallmedia more than generically. (Thank you to a developer on Apple's Developer Forums for pointing out createinstallmedia a few months ago.)
Option two: Use Disk Utility
Y'all'll notice Disk Utility, a handy app built into OS X, in /Applications/Utilities. Here are the steps for using it to create your installer bulldoze, which are a bit more involved with Mavericks than they were with Mountain Lion and Lion.
Note: As mentioned in a higher place, based on my testing, an installer drive created using Disk Utility will not create a Recovery HD partition if your Mac's bulldoze doesn't already have one. You can determine whether or not your Mac has a Recovery Hard disk partition using the instructions in our article on recovery style. If your Mac'south drive is missing the Recovery HD partition, yous should apply the createinstallmedia instructions, to a higher place, as the resulting installer bulldoze will create the missing segmentation when yous install Mavericks.
- Once you've downloaded Mavericks, notice the installer on your Mac. It's chosen Install OS X Mavericks.app and it should have been downloaded to your main Applications folder (/Applications).
- Right-click (or Control+click) the installer, and choose Testify Packet Contents from the resulting contextual carte du jour.
- In the binder that appears, open up Contents, then open Shared Support; you'll run across a disk image file chosen InstallESD.dmg.
- Double-click InstallESD.dmg in the Finder to mount its volume. That volume will announced in the Finder as OS X Install ESD.
- The file you want to become to is actually another disk image inside OS X Install ESD called BaseSystem.dmg. Unfortunately, BaseSystem.dmg is invisible, and considering this is a read-only volume, you lot tin can't make BaseSystem.dmg visible. Instead, you'll mount it using Terminal, which makes it visible in Deejay Utility. Open the Concluding app (in /Application/Utilities), and and so type
open /Volumes/OS X Install ESD/BaseSystem.dmgand press Return. - Launch Disk Utility (in /Applications/Utilities). Y'all'll come across both InstallESD.dmg (with its mounted volume, Os X Install ESD, beneath it) and BaseSystem.dmg (with its mounted volume, Os X Base System, below it) in the volumes list on the left.
- Select BaseSystem.dmg (not OS X Base System) in Deejay Utility's sidebar, and then click the Restore button in the main function of the window.
- Drag the BaseSystem.dmg icon into the Source field on the right (if it isn't already at that place).
- Connect to your Mac the properly formatted hard drive or flash drive you want to use for your bootable Mavericks installer.
- In Disk Utility, find this destination drive in the left sidebar. You may see a couple partitions nether the drive: one named EFI and some other with the proper name you see for the drive in the Finder. Drag the latter—the one with the drive proper noun—into the Destination field on the right. (If the destination drive has additional partitions, just elevate the division y'all desire to apply as your bootable installer book.)
- Alarm: This pace will erase the destination drive or sectionalisation, so make certain it doesn't contain whatever valuable data. Click Restore, and then click Erase in the dialog box that appears; if prompted, enter an admin-level username and countersign.
- Wait for the restore procedure to finish, which should accept just a few minutes.
- In Disk Utility, select BaseSystem.dmg on the left (not OS X Base System) and click the Eject button in the toolbar. This action unmounts the deejay paradigm named Bone X Base Organization. (If you don't exercise this, you accept two mounted volumes named Os 10 Base Organisation—the mounted deejay image and your destination bulldoze—which makes the next stride more than confusing.)
- Open the destination drive—the 1 you're using for your bootable install drive, which has been renamed Os X Base System. Inside that drive, open the Organization folder, and then open the Installation folder. You'll see an alias called Packages. Delete that alias.
- Open the mounted OS 10 Install ESD volume, and you'll see only a binder called Packages. Elevate that folder into the Installation binder on your destination drive. (You're basically replacing the deleted Packages alias with this Packages folder.) The folder is about 4.8GB in size, and so the re-create volition take a bit of fourth dimension, especially if you're copying to a slow thumb drive.
- Eject the OS X Install ESD volume.
- If you like, you can rename your bootable installer bulldoze from OS Ten Base Organisation to something more descriptive, such as Os 10 Mavericks Installer.
(Note that there is a way to perform this procedure that doesn't require Final. Nonetheless, information technology adds other steps, and it requires making all invisible files visible in the Finder. Because seeing all the Finder'due south normally invisible detritus can be a bit disconcerting, I've opted for using Terminal in Step five.)
Option 3: Apply DiskMaker Ten
DiskMaker X (previously called Lion DiskMaker) is a utility that makes it easy to create a bootable OS X install drive, and version 3 supports the Mavericks installer. In fact, under the hood, DiskMaker X 3 actually uses the new createinstallmedia program.
Notes: Because DiskMaker X 3 uses createinstallmedia, it does not work nether Snow Leopard. (The resulting installer drive volition allow you install Mavericks over Snow Leopard, simply y'all can't create the installer bulldoze while booted into Snowfall Leopard.) In addition, DiskMaker X 3 hasn't worked perfectly for me. For example, I experienced an issue where the utility alerted me that it couldn't properly proper name the bulldoze it was creating; however, the installer bulldoze appeared to function properly. If DiskMaker X doesn't work for you, you can use 1 of the other two methods, in a higher place.
- Connect to your Mac a properly formatted 8GB (or larger) drive.
- Make certain the Mavericks installer, chosen Install Os X Mavericks.app, is in your main Applications folder (/Applications). If y'all followed my communication to movement the installer out of your Applications folder, you'll have to movement it dorsum, at least temporarily.
- Launch DiskMaker X.
- Click OK on the warning screen that appears.
- In the Welcome screen, click Mavericks (10.9).
- You'll run across a dialog box alerting you that DiskMaker X institute a copy of the installer in /Applications, and asking if you wish to use this copy. If yous take multiple Os 10 installers (say, Mavericks and Mountain King of beasts), make sure the DiskMaker X message indicates that it has establish the Mavericks installer. If so, click Utilise This Copy. If not, click Use Another Copy and manually locate the Install Bone 10 Mavericks app.
- The next dialog box asks which kind of disk y'all'll be using as your bootable install bulldoze. If you have an 8GB thumb drive, click that push button; otherwise, click Another Kind Of Disk.
- The next dialog box presents a listing of available drives. Select the ane you lot want to utilise and click Choose This Disk.
- Y'all encounter a alarm that proceeding will erase both the selected volume and any other partition on the same disk. In other words, the drive you lot've chosen will exist erased, so make certain information technology doesn't contain any valuable data. Click Erase Then Create The Disk.
- The adjacent dialog box lets you know that yous'll be asked to provide an administrator username and password to build the install drive. Click Proceed; when prompted a few seconds subsequently, enter that username and password.
- Every bit I mentioned in my review of an earlier version of DiskMaker X (then called King of beasts DiskMaker), there will exist times in the process when it appears as if nothing'south happening, so exist patient. One time the process is consummate, DiskMaker X will brandish a confirmation dialog box. Unlike with the Disk Utility approach, DiskMaker X helpfully names the bootable installer book Install OS X Mavericks.
Booting from the installer drive
Whichever of the three processes you've used, you lot can now kick any Mavericks-compatible Mac from the resulting bulldoze: Only connect the bulldoze to your Mac and either (if your Mac is already booted into OS Ten) cull the install bulldoze in the Startup Deejay pane of Arrangement Preferences or (if your Mac is currently shut down) agree downwardly the Choice key at startup and cull the install drive when Bone X's Startup Manager appears.
When your Mac is booted from your installer drive, you can, of course, install the Bone, but yous can also use any of the Mavericks installer'south special recovery and restore features. Depending on how you made your installer drive, when y'all kick from that drive, you lot may even see the same Os X Utilities screen you become when you boot into Bone X Recovery (recovery mode). Notwithstanding, unlike with recovery mode, your bootable installer includes the entire installer.
