I finally migrated my early-2008 Mac Pro to Yosemite, then discovered that my copy of Peak LE 5.2.1 wouldn't run on it. (I start it up, the computer says another copy is already running! Then pfft.) I keep a Snow Leopard boot disk around just to be able to run Peak. The structure of the BIAS upgrade page makes it impossible to move to later, better versions -- no way to pay for them. PLEASE resurrect Peak for the newer MacOSes!
