RE: Anyone using MySQL 4.x on Apple's G5?

[Adam Fortuno]

If memory serves, adjustments to the OS need to be made to take advantage of
the 64-bit memory addressing. I know some changes have been made to OS X to
run on a 64-bit chip, but I'm not certain they've made enough modifications
to take advantage of the memory addressing.

I'd be interested to see how this works on Panther.

Yes.

I wonder why you got cut off at 3.5GB.  I'd have expected OS X on
64bit hardware not to have the weird limitations that, say, FreeBSD or
Linux with kernel reserved memory.

Something is wonky here...

Thanks for the info.  I'd love to hear if you're successful getting
MySQL to use more than 2GB.  I'm gonna hunt around a bit more to see
what others may know.

Thanks,
Jeremy
