If anyone could help- I was running Avid Xpress Pro on a Power Mac G5 Dual 2.3GHz on 10.4.11. Although, having been burned by Avid OS upgrades before, I idiotically purchased AMC version 3.5. I was prompted that I had to upgrade to Leopard (surprise) and more specifically, 10.5.5 or greater. I obliged. After upgrading to OS 10.5.8 and attempting to install AMC for the 3rd time, I was met with another kind dialog box indicating "INTEL REQUIRED. This software requires Intel hardware". Will AMC 3.5 NOT work on my Power Mac?
