Charles, How much RAM do you have? and which version of the OS?
LR4 is a 64bit implementation. It runs best on Lion, and runs best on Snow Leopard when you have Snow Leopard set to boot up with the 64-bit kernel (it's set to the 32bit kernel by default). 4G is enough RAM as long as most other stuff isn't running. I have tested it on a MacBook Air running Lion, but not with an 80,000 image catalog yet. As reality check, I timed startup of LR4.1 on my MacBook Pro 13" system (1 year old, 2.4 Core Duo 2, 8G RAM, Lion, data on the external firewire 800 drive, catalog on the internal). From double click to ready to edit a new directory of raw files was 92 seconds. The MBA did the same startup with a 5000 image catalog and external drive in about 30 seconds. More important, it runs smoothly on both systems after startup. Your system is an older generation than my MacBook Pro 13", 2.5-3 minutes for startup is likely fine. Time to throw money at the problem... I'm planning to upgrade on the next round of MacBook Pro systems too.
