Unfortunately you got caught up in the minor miracle of Rosetta. Here is my complete answer for the OP's benefit: It is slow and iffy.Ĭontrary to intuitive thought, many PowerPC apps running in Snow Leopard Server in Parallels on today's modern day CPU's (i5, i7, etc.) actually run faster than they did on their native G4, or G5, etc. unless you follow Niel's suggestion for emulation.
