I'm trying to install indesign 2.0 on macbook pro - help!!!

Is this ID 2 or ID CS2. I would not be at all surprised if ID 2 would not work or install, that is ancient software. It came our in 2002 and was the first version to support OS X. InDesign CS 2 came out in 2005. It is not intel native. It is quite long in the tooth. This is probably the last chance to update to CS 5.5 without purchasing a new version from scratch. That doesn't really solve your problem. I'd suspect either you have too much RAM or the problem is you might be booting using a 64-bit kernel. Can you check to see if your machine can boot with the 32-bit kernel.
