    I recently started using mac osx, and I was wondering if Leopard, with its 64bit capabilities, makes use of huge amounts of ram- like 32gb in the mac pros. I have a macbook pro and am considering upgrading to 4gb, but I wanted to know how Leopard deals with extra memory. doe sit load more of itself in to memory? Will more memory make coverflow work faster? If Leopard has a huge amount of memory to work with- 32gb for example, will it fundamentally change the way it operates relating to the hard disk or does it only use what is needed by applications as they open?

    OS X works about the same as any other OS. If you want it to pre-load something, and you had 32GB of RAM, you could put a few commands in the bootup scripts to read the files you wanted in to cache.

    So disk caching won't be reduced, overall snappiness will not increase with 32gb of ram?

    Leopard on 32 bit for me has never used all my memory.
