Upgrade from previous versions:
- You can upgrade your existing Lion (10.7.x) and Mountain Lion (10.8.x) installations to Mountain Lion 10.8.2 or make a refresh install to your problematic 10.8.2 system (keeping your applications, user accounts, user settings and user data) by using iATKOS ML2.
To upgrade from Snow Leopard (10.6.x), you should first upgrade to Lion (10.7.x) by using iATKOS L2 or any other methods.
- I advice you to try a clean install to another hdd on your computer before upgrade, to see that if it actually works on your computer or not and to determine your install selection list.
- You will need to re-install your special device drivers after upgrade. i.e. your m-audio firewire sound driver, your 3G modem driver, your ATI video card driver..
- Some of your applications that runs on the previous versions of OS X may not be compatible with Mountain Lion 10.8.2, so know that they may fail after upgrade.
Search for your existing software/driver compatibility for Mountain Lion before upgrading to Mountain Lion.
