Musicians with their eyes on Apple's new Mac Pro should update their copies of Logic Pro or Logic Express to version 7.2.2, which provide compatibility with the Intel Xeon-powered desktop computer. The updates also increase performance through the Mac Pro's architecture and improve support for the built-in audio ports. Logic Pro Update 7.2.2 [1] is a 24 MB download; Logic Express Update 7.2.2 [2] is a 14 MB download. Both updaters require the 7.2.1 version of the respective programs and Mac OS X 10.4.3 or later.
