Hello - I purchased Starcraft2 as a digital download from battle.net, but I am unable to install. On the very first attempt, the installation got to 95%, then the entire machine hung (had to power down). After this initial attempt, I have tried installing after trying a variety of workarounds, including: - disconnecting all external devices (USB, Firewire) except for a USB keyboard and mouse, each directly connected - booting into safe mode - decreasing the resolution (from 2560x1600 to 1600x1200 unstretched) - repairing the disk Every installation attempt results (other than the very first one) gets to 30% and then the entire machine hangs. I also tried re-downloading from battle.net, and doing the fsck -y instructions in single-user mode that Blizzard recommended, and still the installation hangs the machine around 30%. This machine is a Mac Pro 2 x 3.2Ghz Quad-Core Intel Xeon 2 GB 800 Mhz DDR2 FB-DIMM RAM Apple 30" Cinema Display NVIDIA GeForce 8800 GT Please help - thanks !
