    Is it possible to upgrade Mac OSX without going through a new MultiBeast installation?

    But first, you have to update clover, from the clover configurator. If you have an older version of clover, there are compatibility issues.

    Is it possible to upgrade Mac OSX without going through a new MultiBeast installation?

    1) You can try to update directly, but you have to make a backup just to be sure. 2) you have to update the kext module, or install the new ones 3) if you select the right partition there is no problem.
