The trick is to interrupt that process-safely-so you can grab the installer data and keep it. Once that data has been downloaded, Lion Recovery restarts your Mac, immediately installs the OS, and then deletes the installer data. Apple’s servers verify the Mac model and then, assuming it’s a Mac compatible with Lion Internet Recovery, provide the roughly 4GB of data for download. When you use Lion Internet Recovery to reinstall Lion, your Mac contacts Apple’s servers, identifies itself, and requests the appropriate Lion-install data. But because these may not be options if your Mac is having problems, it’s still good to have a bootable installer drive.) (You can also copy the Mac App Store version of the installer to your newer Mac, or download it-all 4GB of it-from the Mac App Store directly to that newer Mac, and then run the installer. Those simpler instructions will create a drive that works with all current Lion-compatible Macs.
As long as your downloaded installer is version 1.0.13 or later-select the installer in the Finder and use the Get Info command to check-there’s no need to perform the procedure below. Note: If you purchased Lion for another Mac, so you have a version of the Lion installer from the Mac App Store, you can use our original instructions for creating a bootable Lion-installer drive. (In our testing, the official OS X Lion USB Thumb Drive doesn’t work with Macs that shipped with Lion-it’s designed for installing the OS on pre-Lion Macs.)įortunately, it’s possible to create a bootable Lion installer even if your only Mac is a newer model, although doing so requires a bit more work.

Apple does offer a utility for creating an emergency Lion Recovery drive but, like the standard Lion Recovery feature, this drive requires you to download the full 4GB of Lion each time you want to install-it’s better to have the full installer on a bootable drive. In other words, you don’t have a downloadable version of the installer unless you happened to purchase Lion for another, older Mac. But if you have a Mac that debuted after Lion (any Mac from July 2011 or later), your Mac shipped with Lion pre-installed.

When Lion debuted, I explained how to create a bootable Lion-installer drive from the Mac App Store version of Lion. (Lion Internet Recovery is available on mid-2011-or-later Macs, as well as some older Macs that have received recent firmware updates.)

And if you’ve got a Mac that doesn’t support Lion Internet Recovery-a version of Lion Recovery based on special firmware-recovery mode may not even be available if your Mac’s drive itself is having problems, whereas a bootable install drive will always be there for you. For starters, Lion Recovery doesn’t include the full Lion installer-it requires you to download nearly 4GB of data before you can reinstall Lion-whereas a bootable installer drive contains the entire Lion installer, making installation much, much faster. But even for troubleshooting, a bootable installer drive has advantages over Lion Recovery.
