Hi there,
Here are some suggestions:
1) Make sure FCP has been upgraded to v7.0.3. Apple fixed a memory
management (leak) issue in the last update. Also install the v8 Kona driver.
2) Temporarily remove any third-party FCP plug-ins other than AJA from:
/library/application support/FCP system support/plug-ins.
3) Remove any third-party quicktime components other than AJA from:
/library/quicktime/.
4) If RAM was recently upgraded then temporarily uninstall and see if
problem is cleared.
5) Delete the Kona preferences:
a) Go to: /library/preferences/ and delete all the com.aja.* files.
b) Go to: /users/username/library/preferences/ and delete
com.aja.KonaControlPanel.plist
c) Reboot.
Please stay in touch.
Best regard
Fitra
