Just wondering how upgrading from Lion to Moutain Lion will work?   Is is a complete clean slate like other opereration systems work (windows) or does is keep your exsisting info, like when you update your iphone?


Just currious on what I will have to do come the next OS upgrade



MacBook Pro, Mac OS X (10.7.2)

    No one here has a crystal ball.  Terms of use forbid speculation, and those who have Mountain Lion are under non-disclosure agreements until it is finalized and released later this summer. One thing you should definitely do is backup your data at least twice:

    Another is watch

    for reports of compatibility AFTER Mountain Lion's release. Only and are reliable when it comes to Mac operating system release info.

    For what it is worth, every major (10.x) new upgrade in OS X since the public beta has allowed for a simple upgrade of your existing version (as long as the existing version was the most immediately preceeding version).  So 10.2 allowed for a simple upgrade from 10.1, 10.3 allowed for a simple upgrade from 10.2, ..., right up to 10.7 allowing for an upgrade of one's existing 10.6 installation.


    So, the odds say that yes, if you have Lion, you should be able to simple upgrade your existing Lion installion to Mnt. Lion without loosing anything.  As with any system update/upgrade, as a brody mentions, you are strongly encouraged to backup everything before upgrading - any software or OS installation/update/upgrade can go awry.
