Running 7.2.0 on a 2.4Ghz Macbook (Intel X3100).
Using the Baldur's Gate 4-in-1 pack, which comes on two DVDs (BG and BG2) and two CDs (ToSC and ToB). Everything installed OK, but I found it beneficial to quit/restart the Bottle after each install to kill any lingering bits of InstallShield - I think this was what caused the main BG2 install to blackscreen a few times.
No need for any disk-swapping shenanigans or minimal installs, just did full custom installs straight off the DVDs. Patches for both BG1/ToSC and BG2/ToB also installed fine. BG1/ToSC seems to work, but I haven't properly tested it.
Mod-wise, Shadowkeeper works fine (yay!) and EasyTutu installed without a hitch, but things got a bit trickier when trying to apply the WeiDU based mods (things like the EasyTutu degreenifier or the BG1 GUI mod) - self extractors would work, but then just freeze up with no visible windows.
Turns out that WeiDU does its interactive question/answer stuff on the command-line, and Crossover Games doesn't provide a command line. However, there is a Mac terminal version of WeiDU (Google it), which works perfectly - use Crossover to extract the executables, force-complete the installations to kill the hung processes, then use weidu-mac to apply the .tp2 files.
The games (BG2/ToB and Tutu) run pretty much flawlessly, and 3D acceleration is working. There's perhaps some slight crackle in some sound effects (such as the eagle screeches), but I'm not going to be picky. No problems with CD detection or anything like that.
I will do some testing of vanilla BG1/ToSC at some point - if that works, Planescape Torment might be feasible...
