What do I need to create a bootable USB MacOS Installer In this article, I will show you how you can easily create a Bootable USB MacOS Installer drive which you can use to install on any Mac computer. You’ll now have your bootable Lion DVD.Did you buy a new Mac and you are looking to install a different MacOS version to it? Or you are looking to install MacOS Monterey (the latest MacOS at the time of writing this article) to an unsupported MacOS computer? When the DVD is done burning, it will automatically eject. This process could take 20 minutes or more. Insert a blank DVD, and click the Burn button. Select InstallESD.dmg and then click on the Burn icon in Disk Utility.

Now you’ll have a bootable OS X Lion image on USB. Warning: This will erase all contents on your USB drive! Navigate in the Finder to Applications>Utilities and launch Disk Utility.Ĭlick and drag your USB drive (in this case it’s called “8.03 GB Corsair Voyager”) into the Destination field. You’ll have to wipe the drive in order to put the Lion installation on it. Note: You’ll first want to save all information on the drive. If you wish to use DVD, then skip to the part where you’ll insert your DVD. First I’ll show you how to do this using a USB drive. This is where you’ll have the choice to either create your Lion installation on a USB drive or a DVD. Navigate to Applications>Utilities in the Finder and launch Disk Utility. Then click on Edit again and choose Paste Item. Now, with this file selected, click on Edit in the menu bar at the top of the screen, and select Copy InstallESD.dmg.Ĭlick on your desktop wallpaper so the menubar at the top says Finder. Now hold down the control key while clicking on the Install Mac OS X Lion icon, and choose Show Package Contents.įind and double-click on the Shared Support folder.Ĭlick once on the InstallESD.dmg file to select it. Once it’s done downloading, go to the Finder and look for the Install Mac OS X Lion icon in the Applications folder. This will take some time, so you might want to do something else and come back to it awhile later. It will be located on the right hand side under Quick Links.Īfter clicking download, you’ll be taken to Launchpad (if you’re already using Lion).

First launch the Mac App Store and find OS X Lion.
