I'm using 10.4.4
Upgrading to 10.4.7 did the trick
Thanks a lot for the help.
After updating to the new OS "Catalina", im getting a strange error in FCPX.
I'm getting the error when I try to import one of the "build in" sound effects to my project.
Im not getting this error when I import video. Also im able to import custom sound effects, downloaded from the internet.
I have 300GB available space on my hard drive, on my 2019 MacBook Pro.
Can anybody help me ?
