If you have already upgraded your computer to OS X Lion, but forgot to save a copy of the installer to create a bootable installer, you are not alone. Having a bootable installer allows you to quickly and easily rebuild your system in the event of an incident without having to install Snow Leopard from disk and then upgrading using the Mac App Store. Well, there’s an easy way to get that installer and burn an installer disk, giving you that warm and fuzzy feeling.
This tip and trick will work to force download any app that you have purchased on the Mac App Store.
Here’s how you do it:
1. Open the Mac App Store application
2. Navigate to your Purchases page
3. Hold down the Option key and click on the OS X Lion icon on the left hand side of the screen. Do not click on the Installed button.
4. You will be taken to the Lion product page. Hold down the Option key and click on the Installed button. If you haven’t already authenticated to the App Store you will be prompted for your login credentials, otherwise the download will start.
Once completed, you can then save the Installer DMG to another disk or burn a DVD. We’ll cover that in an upcoming post.
