Public Beta Availiable - Win/Mac/Firmware [UPDATED]

[Jean-Michel]

Hello

Which version of Mac OS is it compatible with? I have 10.7.5 and both KC and VC extracted from the DMG files crash.
I did not update the OS for a long time because I wanted to keep it as stable and reliable as it was the very first day I got it. One can read almost everything about updates on the internet and without anyone to help you it is difficult to make one's own opinion and decide whether it is a good thing or not to update, and up to which version, since some seem to be criticized and not stable.
Help much appreciated!
Sorry for kind of polluting this thread with this side topic.

Kind regards.
