Now running with Snow Leopard 10.6.8. Only issue was that I had to add the PCIRootUID=1 to get the install to complete, but a real breeze after that. Thanks to TonyMacX86. _________________ • MB: Asus Gigabyte GA-X79-UD3 • CPU:i7-3820 running at 3.6Ghz • RAM: CORSAIR Vengence 16GB DDR3 1600 • GPU: Sapphire Radeon HD6850 • Cooler: Xigmtake Aegir SD 128264 • System HDD: OCZ Agility 120GB Datastore HDD: Seagate ST31000340AS • Optical: Pioneer DVR-S19LBK • Audio: Digidesign HD Core Card PCI • Audio: 2x Digidesign 192 I/O interfaces • Midi: Digidesign Midi I/O • Preamps: Digidesign PRE • Control Surface: Digidesign C24 Been running for several days now and not had a single issue, even when running a session with 68 tracks, and over a hundred plugins, including some of the the new AAX format.
