If you, like me, are keen to get your hands on the latest and greatest Mac operating system, OS X 10.13 a.k.a. High Sierra then hold your horses, especially if you use the Olympus DSS Player Plus for Mac software for transcription or to listen to your .ds2 audio files.
After my upgrade from Sierra 10.12 to OS X 10.13 when I ran DSS Player Plus v7 (v7.5.3) for Mac I was prompted for my serial number:
This was immediately odd as this was entered long ago when the software was first installed but I played along and entered my license key, in fact I entered several serial numbers that I have, all with the same result “The license number you have entered is incorrect. Please confirm your license number.“:
Looks like a compatibility issue with Olympus DSS Player Plus v7 and Apple’s latest OS X 10.13 – our advice is to hold off updating until this is resolved. We have notified Olympus and will update this post with news as and when we get it.
