Make sure neither os x install esd mounted mac os x#
New Mac OS X named out of Cat family which is called “Mavericks”. (You're basically replacing the deleted Packages alias with this Packages folder.) The folder is about 4.8GB in size, so the copy will take a bit of time, especially if you’re copying to a slow thumb drive.WWDC 2013 Apple showed their new operating system for the Mac. Drag that folder into the Installation folder on your destination drive. Open the mounted OS X Install ESD volume, and you’ll see only a folder called Packages. Inside that drive, open the System folder, and then open the Installation folder. Open the destination drive-the one you’re using for your bootable install drive, which has been renamed OS X Base System. (If you don’t do this, you have two mounted volumes named OS X Base System-the mounted disk image and your destination drive-which makes the next step more confusing.) This action unmounts the disk image named OS X Base System. In Disk Utility, select BaseSystem.dmg on the left (not OS X Base System) and click the Eject button in the toolbar. Wait for the restore procedure to finish, which should take just a few minutes. Click Restore, and then click Erase in the dialog box that appears if prompted, enter an admin-level username and password. Warning: This step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data. (If the destination drive has additional partitions, just drag the partition you want to use as your bootable installer volume.) Drag the latter-the one with the drive name-into the Destination field on the right. You may see a couple partitions under the drive: one named EFI and another with the actual drive name. In Disk Utility, find this destination drive in the left sidebar. Select BaseSystem.dmg (not OS X Base System) in Disk Utility’s sidebar, and then click the Restore button in the main part of the window.ĭrag the BaseSystem.dmg icon into the Source field on the right (if it isn’t already there).Ĭonnect to your Mac the properly formatted hard drive or flash drive you want to use for your bootable Mavericks installer. You'll see both InstallESD.dmg (with its mounted volume, OS X Install ESD, below it) and BaseSystem.dmg (with its mounted volume, OS X Base System, below it) in the volumes list on the left. Launch Disk Utility (in /Applications/Utilities). Open the Terminal app (in /Application/Utilities), and then type open /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg and press Return. Instead, you’ll mount it using Terminal, which makes it visible in Disk Utility. Unfortunately, BaseSystem.dmg is invisible, and because this is a read-only volume, you can’t make BaseSystem.dmg visible. The file you want to get to is actually another disk image inside OS X Install ESD called BaseSystem.dmg. That volume will appear in the Finder as OS X Install ESD. In the folder that appears, open Contents, then open Shared Support you’ll see a disk image file called InstallESD.dmg.ĭouble-click InstallESD.dmg in the Finder to mount its volume. Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu. It’s called Install OS X Mavericks.app and it should have been downloaded to your main Applications folder (/Applications).
Once you’ve downloaded Mavericks, find the installer on your Mac.
