[QUOTE="pigoo3, post: 1604779, member: 56379"] Not really super important...since the oldest OS a Mid-2013 MacBook Air can run is 10.8.4. Suffice it to say that...there are older Apple computer models that can run 10.6, 10.7, 10.8, 10.9...and soon 10.10...without too much trouble.:) That would be a correct assumption.:) As with all versions of Mac OS X (since OS 10.0 was released almost 14 years ago)...when you launch the installer...by default...the new OS version simply replaces the old OS version (leaving all other files & apps that are installed untouched). It would be a pretty unfriendly installer if it automatically erased everything...thus the owner loses all their apps, files, photos, movies, music, etc. If you wanted everything erased...then you need to boot the computer from the recovery partition (press command + r on reboot)...or boot the computer from a bootable external HD or bootable USB stick. Why wouldn't it be...it's the newest Mac OS version with the newest security support.;) I think that you need to explore this yourself. You seem to know 10.6 pretty well...so compare & contrast.:) It's kind of like saying...[i]"I've been asleep for the past 100 years...bring me up to speed on everything that's happened since 1914!"[/i];) - Nick p.s. Probably three BIG differences from 10.6 to 10.9 are: 1. After 10.6 there are no more physical disks (downloadable OS versions). 2. With OS 10.7 & later you have a "Recovery Partition" on the HD (accessed as I mentioned above). 3. If a brand new HD or SSD were installed (which would have no recovery partition on it)...you have what is called "Internet Recovery". If these terms are new to you...and you want more info on them...get Googling!;) [/QUOTE]
