How to get OS X Lion and Mountain Lion Prior to June 2021, you could purchase OS X 10.7 Lion or Mountain Lion from Apple for 19.99/£19.99 each Apple would send you a download code. Step 1ĭownload Lion from the App Store – remember, DON’T install it! Step 2 If you don’t have a Time Machine backup, you can always do a factory restore and start again. What I did was to recovery a previous backup using Time Machine and then started the process again, only this time I just did the download, I didn’t do the upgrade. If you have already downloaded and upgraded to Lion then the files won’t be there on your Mac as they are deleted once the upgrade has completed. Also, for the Mac OS X Lion book I am working on I needed to do some screenshots of a clean configuration (for those readers who just bought a new Mac with Lion installed), so I wanted to have either a DVD or a USB stick with the Lion media on.Īfter reading through various materials, this is the method I used. However, I also don’t want to wait several hours with my slow internet connection if I have to do a recovery or a reinstallation. Ok, so the download and upgrade to Lion went well for me, I didn’t have any problems. If you want to perform a clean install of Mac OS X Lion instead of an upgrade, or you want to have some recovery media available, just in case, then this is the how to guide for you. ![]()
