I am curious if there is any reason to download an updated version of Darwin and then 'recompile' OS X? I hear linux users always talking about how recompiling an OS makes it better/faster/leaner, can we get benefits from doing this with OS X? Also can jaguar be recompiled with panther's version of Darwin, and if so would it just be majorly buggy or would we see any differences for the good? I understand that aqua/quartz/cocoa/iLife etc. are not free or available to be recompiled so I am not expecting any differences at the gui level, just in the speed and possible stability level. So any one who is braver than me try this out already, and how'd u do it?? Thanks for the help guys, and I looked in a couple other threads but they basicly went like this.
