For all Phase One Capture One 6 users its still worth noting that there a a few issues with it and Lion, below is what Phase One have to say.
This was posted on Phase One website 16th August 2011
"With the recent release of Apple's Lion OS (10.7) there have been several reported issues with the use of Capture One 6.2.2. We thank all of you for bringing these to our attention and reporting the errors with such diligence.
Unfortunately, we are not ready to release a fully supported version of Capture One 6 for the Lion OS and we must, until that time, point out that 6.2.2 does improve Lion compatibility but there are still a number of known issues.
We are working hard to ensure we can provide a safe and stable software to accommodate the changes in Lion and apologize for the time it has taken to do so.
Until an official release of Capture One 6 with specific support for Lion is available, we must recommend that Capture One 6.2.2 not be used with this Operating System. We thank you for your patience while we address these changes.
Known Issues include:
•Import Feature Stall / Crash
•Edit Keyboard Shortcuts Stall / Crash"
