According to AppleInsider, Apple has made Mac OS X 10.5.7 available to its employees on internal servers, indicating that the public release is around the corner. We take this opportunity to remind you some important points when applying an OS update:
Perform a backup before installing the OS update (and/or clone your current system). It will give you the opportunity to come back to the previous version while providing a backup of your file as HD crash frequency is higher during OS update.
If you experience some weird bugs following the update, try to apply the "Combo" update.
If you rely on your computer for Pro and intensive usage, do not update your current system before it has been extensively tested by mass users before. You can also clone your system on a external HD or trial computer then perform the update on this one to evaluate all potential issues. Damaging problems are hopefully rare, however conflicts can make your life difficult to make you loosing a lot of time
