Hi, I'm trying to build 10.5.6's AppleFan.kext, but it's failing as follows: bash-3.2# darwinbuild -init 9G55 ...

The error appears to be correct: the AppleFan package contains a Project Builder project rather than an Xcode project. Thanks, Jonas PS: I want to recompile that kext with the debugging code enabled, because the CPU B intake and exhaust fans constantly remain at idle speed (300 rpm) on my dual G5, resulting in lots of noise from the CPU A fans doing overtime as soon as the system gets slightly loaded. It's not that the CPU B fans cannot spin faster anymore (they work fine when the Apple Hardware Test cd tests them), nor that the temperature sensors are broken (the temperature sensors of CPU B consistently show a higher temperature than those of CPU A). While it does not appear to be a (pure) software problem either (booting in 10.3.4, the OS version the machine originally came with, does not appear to solve the problem), I'd like to take a look at what the kext is telling the fans to do.
