So I am checking Editing Software Compatibility of Mac OS X Lion.
As Apple Said Final Cut Pro 7.0.3 does open fine in Lion, though it does ask me to register, though the button to register is grayed out.
The Demo of AVID Media Composer 5.5.2 boots and runs just fine.
Adobe Premiere Pro 5.5 I am having issues with. and it won’t start. Adobe claims it should run fine, so I am going to try and re-install and see what happens. It is weird as After Effects and Photoshop work fine, but just Premiere won’t boot.
