Since upgrading to MacOS Sonoma this morning, I am no longer able to play my old precious mpg movie files on QuickTime Player. Yesterday, before upgrading, they were playing with no problems.
MacBook Air 13″, macOS 10.14
Yes, the information was helpful eventually. Thank you. My software updates were all up to date, so that didn't solve it. Instead I downloaded 'Final Video Player' from the App Store and can now play the videos. But I'm still a little disappointed in Apple and now more wary of OS updates as I wonder what capabilities I will lose in the future.
Thanks anyway.
