Unable to play any video on MacBook Pro 2018 with Touch Bar
I am not able to play any video at all on my MacBook Pro 2018 Model Apple T2 Security Chip. I tried resetting the NVRAM and SMC. There is no luck. I can't watch videos on any website like YouTube , Vimeo etc. It worked all fine before few days when I clicked update Mac button. It just loads a spinner and sits there, No video playback. Same with Quick Time or VLC player. VLC player starts the playback but it stops working when I run through the video using the timeline slider.
Is there any other way to reset the machine to default settings so I can use the laptop at least for some basic work.
running now macOS Big Sur
shipped OS High Sierra
