Not to rain any parades, but you will not be able to eliminate the Type 2 errors completely. There are less of them with the patch installed but, it is still next to impossible to keep Carrara stable on the Mac. I have been trying for over a year to keep it running in a productive sense on 3 different Macs. There are periods of clarity and smoothness, but then the simplest things will send it into fits of type 2 and type 3 errors. It doesn't matter how much ram you give the application; in one case, I have given it 320mb of ram with no improvement. After keeping track of the activities that cause the crashes/freezes, it is obvious to me that how Carrara accesses memory or a bug in how it utilizes that memory is the source of Mac Carrara problems. The system version impacts it as well. The most stable version seems to be 8.51. Unfortunately, I prefer system 9.04, and that is less friendly with Carrara. I'm now installing system 9.1 on one machine and will test Carrara on that - fingers crossed. If you haven't already, you can turn off all extensions, except the ones needed for basic functionality, turn off virtual memory, allocate the maximum memory you can to Carrara and don't run any other programs at the same time. You then may have a chance of keeping it stable, but you'll also have to trash the preferences when the type 2 errors start again. My personal opinion, backed by 15 years of Mac fanaticism and tech support for the graphics industry, is that Carrara is broken (or was never finished) on the Mac and needs to be redone. The new owners are facing a real challenge in this regards, because of the imminent release of OSX.
