Here is a link that describes what is contained in the release: http://www.apple.com/macosx/apps/all.html
Due to be released in July 2011, Lion will only be available via the Application Store Application that is installed on your computer instead of the normal DVD you would purchase online or from a store. The Application Store concept downloads software as iTunes downloads music.
If you bought your computer after June 6, 2011, the upgrade to Lion may be free. Click on this link to see if you qualify: http://www.apple.com/macosx/uptodate/
It not unusual that application software you currently have installed will not run with a major Operating System upgrade such as Lion as this is the case with Quicken. Do your research carefully on what the real cost of the upgrade will be for example if you have to buy new versions of applications that run fine on your current Operating System, it may be more expensive than anticipated.
Once you decide that you want to upgrade, how do you tell if you meet the requirements to upgrade your computer?
- If you are running an Apple computer that does not have an Intel Processor such as an iBook G4, you cannot install Lion. The last Operating System release that supported your computer was Leopard (10.5.8). How do you tell what release of the operating system you are running and if you are running an Intel Processor? Click the Apple Icon in the upper left corner of your screen and select About This Mac.
- If your computer processor is an Intel Processor, you must have Snow Leopard (10.6) loaded on your computer to have the Application Store App loaded on it. Therefore, you cannot upgrade directly from a pre-Snow Leopard release of the Operating System to Lion. You must purchase Snow Leopard first for $29.99 from a store or online vendor and install it in order to have the Application Store App installed.
- Once you meet the requirements for an upgrade to Lion, purchase and download Lion from the Application Store. I would suggest you wait a week or so after Lion is available to see if you can expect any problems with the upgrade.
