So, I recently installed Parallels 5 on my MacBook and then I installed Windows 7 as a virual machine. For some reason, I cannot get Windows 7 to run in "aero" mode. The MacBook I installed it on is a year or two old (it's a Black MacBook). It's got a 2.4 GHz Intel Core 2 Duo and 2 GB 667 MHz DDR2 SDRAM. I believe the sceps are enough to support "aero" mode. In the virtual machine configure menu. I've selected Processors = 1 and Mani Memory = 1200 MB (top of recommended). When trying to adjust my settings in Windows 7, there is a message at the bottom of he personalization screen with a link to "Troubleshoot problems with transparency and other aero effects". When I click the link, it runs a test to detect problems. After the test is complete, it tells me that Desktop Window Manager is disabled. Any idea on what I can do to get Aero working, or is my macBook not up to snuff? Thanks!
