there are many conflicting opinions and methods here and elsewhere for getting to mavs on a macpro1,1. mine is stock dual 2Ghz Xeon. I have 5G ram currently and will upgrade to 8G. I'd like to run Mavs. I have an install on my MBA and on a 10.9.2 USB stick. Would someone point to the most recent and/or best method? I assume using the tiamo methodology?
