Speaking (or at least) writing as someone who has not upgraded to Lion from Snow Leopard I would consider the software compatibility angle very carefully before upgrading if you use slightly older non-Apple titles. If you don’t fall into that category then probably for the price it isa no-brainer. The upgrades may be cheap but the consequences are not. Regards.

Download only. However, do you have a particularly strong and pressing need to upgrade to Lion? If you're going to take this path, be sure all your software is compatible; http://osxdaily.com/2011/07/15/how-to-check-if-applications-are-incompatible-with-mac-os-x-lion/ http://gagagadget.com/wordpress/2011/07/os-x-lion-what-works-and-what-doesnt/ For example, unless you have the latest MS Office 2011 for Mac, you're going to find yourself having to upgrade. On the other hand, if all of this is OK by you but you're not desperate to upgrade, wait a couple of months and go straight to Mountain Lion and save bit of cash on upgrading twice :) http://www.apple.com/uk/macosx/mountain-lion/ On Wed, May 16, 2012 at 8:10 AM, David Weston <david@xxxxxxxxxxxxxxxx<mailto:david@xxxxxxxxxxxxxxxx>> wrote: Hi, How do I change my imac from SL to lyon?
