Hello, I just Wonder if PM5 is full compatible with Apple OS 10.9 Mavericks before I update?
PM 5 and PM 4.6.9 both appear to be very compatible with Mac OS X 10.9 in our testing with pre-release builds of the new OS. We haven't tested the full release version yet, but we don't expect any issues.
Though I always recommend letting other people upgrade and report bugs to Apple. Wait for 10.9.1...
