I don't think I'll need to go any higher than this. I have a license for Adobe CS3 Premium, which I will install on the MBP. appears to have a pretty decent listing of app versions for Snow Leopard (although not specifically 32-bit) and Leopard (Intel). It would be good to see a website which can outline all of the specific versions of Mac software which were 32-bit compatible before Apple find a way to obliterate 32-bit existence completely (as they have done with PowerPC). Thanks, I don't have anything specific I'm looking for. It shipped with 10.4.5 (and it is fast), but it seems Leopard's optimizations were very much Intel (32-bit) focused, with PowerPC speed priority taking second place. I know it was designed to originally run with Tiger. It feels very snappy compared to Snow, even at the throttled speed. I will try to avoid resorting to Windows though, but at least it is an option. My understanding is it will have the same hardware speed throttling.

But for about $10 more, I can just buy a cheap eBay special Chinese knock-off battery to suit and also make the Mac portable again, so I'll go with that instead.

CoolBook registrations are per machine and it locks itself to the hardware (I have one reg for my C2D MacBook uni '08 which works only up to Snow Leopard 10.6.8). If I register another copy of CoolBook, I can also override the stepping and force the MBP to run at full speed.

I get about 10 seconds of 1.83Ghz before it deems the battery unworthy and locks itself back down to 1Ghz. Using CoolBook, I can watch the stepping 'unlock' after I remove the battery and reinsert it. Yes, it was typical behaviour for the MacBook and MacBook Pro to throttle CPU speed when the battery is removed (or too far gone to properly register).
