Install disk creator for 10.7.53/18/2024 One of these three procedures should get rid of the “Installed” status for Lion and let you download it. If that doesn’t work, quit the Mac App Store app and then hold down the Option key while launching the Mac App Store again. If that doesn’t work, switch to the Mac App Store’s main page and then Option+click the Purchases button in the toolbar. As I explained in our main Lion-installation article, you should be able to force a re-download using one of the following three tricks: First, Option+click the Buy App button in the Mac App Store. If you’ve already installed Lion-so it’s too late to move the installer-you’ve may find that the Mac App Store claims that Lion is already installed and prevents you from downloading it again. If you don’t, you’ll have to re-download the entire thing from the Mac App Store. So if you plan to use that installer on other Macs, or to create a bootable disc or drive as explained here, be sure to copy the installer to another drive-or at least move it out of the Applications folder-before you install. Note: As explained in our main Lion-installation article, if you leave the Lion installer in its default location (in /Applications) and use it to install Lion on your Mac’s startup drive, the installer will be automatically deleted after the installation finishes. You can also use any of the Lion installer’s special recovery and restore features-in fact, when you boot from this drive or DVD, you’ll see the same Mac OS X Utilities screen you get when you boot into restore mode. You can now boot any Lion-compatible Mac from this drive or DVD and install Lion. When prompted, insert a blank DVD (a single-layer disc should work, although you can use a dual-layer disc instead), choose your burn options, and click Burn. In Disk Utility, select InstallESD.dmg in the sidebar You can use Disk Utility’s Restore screen to create a bootable flash drive or hard drive. However, with the 10.7.4 installer, you must use the mounted Mac OS X Install ESD volume or you will get an error at the end of the restore procedure and the newly created bootable drive may not function properly. Note: In versions of the Lion installer prior to 10.7.4, you didn’t need to first mount the InstallESD.dmg image-you could simply drag the image itself into the Source field. The restore procedure will take anywhere from five to 15 minutes, depending on your Mac and the speed of your drive.
