Requirements to install all Final Cut Studio applications
* Mac computer with an Intel processor
* 1GB of RAM (2GB of RAM recommended when working with compressed HD and uncompressed SD sources; 4GB of RAM recommended when working with uncompressed HD sources)
* ATI or NVIDIA graphics processor (integrated Intel graphics processors not supported)
Those requirements are from July 2009 when Final Cut had it's last major update and refer to the old Intel GMA 950 and X3100.
Has it been officially confirmed that the new Intel HD 3000 graphics are not supported?
