I totally agree. The original MacOS absolutely dumbfounded me with the way it operated internally for a lot of things... Tried programming MacOS 7 & 8 versions. Not entirely pleasurable, and requiring users to set the memory to be used by an app when it is supposed to be user/beginner OS friendly absolutely confounds me, although I can see how the older architecture caused this to happen. MacOS X is seriously tempting me, though... It is seriously nice to use... but will stick with Amiga for the mo.
Apologies for being a bit off-topic. I have no idea how to get the new Macs to switch on/off.
