When you do so, youвЂ™ll find yourself with a screen called Mac OS X Utilities with several options.

BEST MAC CLEANER FOR SNOW LEOPARD HOW TO

(If youвЂ™ve already got your copy of the Lion installer, skip this step.)Д¬reate a bootable Lion-installer drive using the instructions in How to make a bootable Lion install disk or drive.Д«oot your Leopard Mac from that new Lion install drive. Use the Snow Leopard or Lion computer to download the Lion installer from the Mac App Store. (For this purpose, I recommend a clone.) Be sure to test this backup to verify that it has your latest data: In the case of a Time Machine backup, try restoring some important data from the backup in the case of a clone backup, boot from the clone to make sure it boots and that it contains all your data. Make sure you have an up-to-date backup-either a Time Machine backup or a clone backup using a utility such as SuperDuper or Carbon Copy Cloner-of your Leopard MacвЂ™s hard drive. (If this sounds a lot like a clean install, thatвЂ™s because itвЂ™s essentially the same process.) HereвЂ™s are the steps to take:

You just erase your MacвЂ™s drive, install Lion onto it, and then import all your data from your backup. So as long as you have a good backup a 4GB-or-larger thumb drive or external drive and either access to a Mac running Snow Leopard or Lion, or an already downloaded copy of the Lion installer, you can perform a bit of installer razzle-dazzle.

It will, however, install onto a blank drive, so Lion clearly doesnвЂ™t need any of Snow LeopardвЂ™s files or settings.ДЄs I mentioned above, the Lion installer will let you install Lion onto a bare drive when the installer itself is run under Snow Leopard or Lion. Based on our testing, the Lion installer refuses to install Lion onto a drive containing Leopard (10.5) in fact, it refuses to install on any drive running a version of Mac OS X below 10.6.6. So then the question becomes whether there are any technical reasons you canвЂ™t install Lion over Leopard. In other words, in our view, you should be well within your rights to install Lion on any of your computers for which you have a valid, current Snow Leopard license-even if you donвЂ™t install Snow Leopard on it first.

BEST MAC CLEANER FOR SNOW LEOPARD LICENSE

While the letter of the law says you need to install Snow Leopard before installing Lion, the spirit of the law seems to be that a particular Mac just needs a license for Snow Leopard before you can install Lion on it.

BEST MAC CLEANER FOR SNOW LEOPARD UPGRADE

Having performed this two-step upgrade many times while researching our various Lion-installation articles, I can tell you that itвЂ™s a real hassle.)Д«ut lets take a step back. (This is just one scenario-I can think of a number of situations in which you might have Leopard on a Mac or an external hard drive, along with a valid license for Snow Leopard, and youвЂ™d rather not take the interim step of installing Snow Leopard just to upgrade to Lion. But what if, for example, youвЂ™ve got a family-pack license for Snow Leopard, and youвЂ™ve got a Mac that shipped with Leopard but that you never upgraded to Snow Leopard? Assuming that Mac is compatible, the Lion license agreement says you canвЂ™t upgrade to Lion until you first install Snow Leopard. If you didnвЂ™t purchase Snow Leopard, you canвЂ™t install Lion. If your Mac shipped with Leopard, but you later purchased Snow Leopard for, and installed it on, that Mac, you can install Lion on it.

BEST MAC CLEANER FOR SNOW LEOPARD SOFTWARE LICENSE

The software license you agree to when you install Lion states that you can вЂњdownload, install, use and run for personal, non-commercial use, one (1) copy of directly on each Apple-branded computer running Mac OS X Snow Leopard or Mac OS X Snow Leopard ServerвЂ¦that you own or control.вЂќ In other words, if your Mac shipped with Snow Leopard, you can install Lion on it. In other words, you need Snow Leopard just to purchase and download Lion.Д«ut once youвЂ™ve got your copy of Lion, can you install it onto a Mac or a hard drive containing Leopard (Mac OS X 10.5)? The main practical reason for this requirement is that Lion is available only via the Mac App Store, and the Mac App Store debuted in Mac OS X 10.6.6. As I explained in Installing Lion: What you need to know, one of the requirements for installing Lion is that you already have Snow Leopard (Mac OS X 10.6) version 10.6.6 or later installed.
