USER MANUAL for USB to serial converter (PL2303)

What does this problem mean?
A: This problem occurs because the PL-2303 MAC X driver was compiled
under OS 10.1.X. So when you install the driver under OS 10.2, it will
show this warning message. User just need to select the "Fix and Use"
button to make it work under OS 10.2.X.
