</div>I'd install fc12 although I have not yet remade the planetccrma-apps<br>
meta package. Newer kernels mean better support for newer hardware, I<br>
don't know if that is the case with your macbook (there's going to be a<br>
2.6.33 based rt package very very soon).<br>
<br>
At ccrma we still run 32 bit Fedora on all workstations...<br>

</div>Well, pd is not yet there for 64 bits (the latest pd-extended official<br>
release, not the plain pd which I think may be happy in 64 bit envs).<br>
And chuck is still happy only in 32 bit land. It may be possible to<br>
install and run the 32 bit binaries in a 64 bit environment but I have<br>
not tried (and will not try :-)<br>
<br></blockquote><div>A recent test I read proved that a 64 bit (Linux) system has better performance than a 32 bit (I'll dig it up if someones interested) but I'm happy to swap that potential performance improvement for compatibility and stability.</div>
