Pioneer BDR-XS06 external player won't play blu ray discs
Been using a Pioneer BDR-XS06 blu ray/dvd burner/player for about a year to rip purchased blu ray movies to my 2016 iMac HD. Started having issues with ripping the movies (use Make MKV ripping software) so I assumed it was the drive itself or Make MKV had a problem. No.
Calls to Pioneer and Make MKV both resulted in them pointing me back to Apple.
Can anyone confirm for me if the latest OS X updates to either Sierra or High Sierra (I am running HS) could cause the drive issues that I now have? Pioneer doesn't think it is their hardware (the movie will mount to the desktop), also reads DVDs no problem. Make MKV thinks it is the Apple driver.
Thanks.
iMac with Retina 5K display, macOS High Sierra (10.13.1)
