Well install went great. Im running a mac pro 2.66 Octo that i upgraded myself. So you cant even call it official mac hardware anymore. iMac 24", iMac 17" and 2 Macbook Pro's 15" Photoshop CS3 installed great Maya 2008 installed great LIttle Snitch 2 Beta 10 works great Need to wait for some apps to update like iDefrag and Super Duper. Understandable since there very thorough. Best new surprise feature i found was the fact i can resize my partitions on the fly without erasing the volume. Worst new surprise is stacks dont support nested folders. Overall I love it. Sorry to see so many having issues. I'd recommend erase and install always.
