Haven't encountered an installed app that won't run as of yet...which I guess I shouldn't expect to?Well, it's not so much "more efficient use of RAM" but "capable of using more RAM." The Intel 32-bit architecture cannot address more than 4 Gb directly. There are indirect methods to do so, but they are a bit tricky. I don't know how Apple managed the issue, but in the Windows world at least, Microsoft opted to not allow consumer-level machines and low-end servers (which, back in the days before AMD64 and E64T extensions, didn't even have enough sockets for more than 4Gb anyway) to use those indirect methods. Rule of the thumb: if you have less than 4Gb of RAM, 64-bit mode won't make much of a difference. If you have 4Gb, depending on a number of factors, you may see some more free RAM. If you have more than 4Gb, you probably should be using 64-bit mode.Which is probably why my Book now feels "snappier" - I have 8G of RAM in it.Mine does as well , though some software doesn't seem to make any difference. For me SeaMonkey, FireFox 3 and 4, Camino didn't seem to benefit. Chrome, iCab. iCab does best I am using version specifically for 64 bit. I don't use Safari all that much so I can say.
Yeah...I don't use Safari much either now that I can browser spoof.BTW - I also discovered that running 2.1b3 alongside my 2.0.13 install torched my more important cookies on my iMac by blanking everything to defaults and I had to rebuild them by grabbing the files off my PowerBook profile. I won't be doing that again - make sure the final release maintains previous content, please!
