That said, if, for whatever reason, you absolutely need to create a bootable install DVD, follow steps 1 through 5 under “ Using Disk Utility,” below, but from Step 6 on, follow the instructions under “To create a bootable DVD” in our article on making a bootable Lion-install drive.

In addition, you can easily update a USB stick or external hard drive each time an update to Mac OS X is released, as explained below with a DVD, you have to toss the disc in the trash and start over, which is both a hassle and bad for the environment.

Finally, if you need to install Mountain Lion over Leopard-assuming you have the license to do so-a bootable install drive makes it easier to do so. (Mountain Lion’s OS X Recovery feature, known as Lion Recovery prior to Mountain Lion’s release, is a big help here, but not all Macs get it-and if your Mac’s drive is itself having trouble, recovery mode may not even be available. Also, if your Mac is experiencing problems, a bootable install drive makes a handy emergency disk. But there are a good number of reasons you might want a bootable Mountain Lion installer on an external hard drive or a thumb drive (USB stick).įor example, if you want to install Mountain Lion on multiple Macs, a bootable install drive can be more convenient than downloading or copying the entire Mountain Lion installer to each computer.
Like Lion (OS X 10.7) before it, Mountain Lion (OS X 10.8) doesn’t ship on a disc-it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc.
