With Mac OS X Lion due any moment, Final Draft has released version 8.0.2, which should allow it to launch:
Final Draft v.8.0.2 has been engineered to run on OS X 10.7 (Lion). It’s available as a free download HERE.
V.8.0.2 is the only version of Final Draft that will work on this operating system. Final Draft v.7 and older will NOT work on Lion.
The free 8.0.2 installer is an operating system-specific patch with no new features or fixes other than 10.7 (Lion) compatibility.
You have to log in with your FD registration number to get to the installer, which feels clunky in the age of auto-updaters. But it’s otherwise painless.
I don’t have a Lion beta to test it against, but the updated app seems to work properly under 10.6. Upon launch it asked me to activate again, which gave me a moment of panic. The online activation worked without incident, however.
