I am really hoping someone might be able to help :
I’ve been running a MacBook Pro 2018 on Mojave relatively successfully for about a year and a half so far (though clearly not as confident in the hardware and OS as I used to be with my previous apple equipment).
3 days ago (and I don’t know if this is just a coincidence or not but I had just installed DaVinci Resolve the day before), I noticed that whatever video I tried to play on either VLC or youtube would start playing way too fast after a few minutes, like a progressive fast forwarding (not like “play a 2 hour film in 4 minutes” but enough that it is disturbing). Sound pitch doesn’t seem to be too altered, though, it is very weird, and it is worrying on a number of levels for the film editor that I am.
It happens both on VLC, youtube, quicktime player, you name it… I have no idea where it comes from : there are no peripheral devices attached to the computer.
I read about a coreaudiod issue “fix” on the web , so I tried force-quitting the coreaudiod task on the activity display, to no avail, the problem comes back almost immediately.
rebooting multiple times, resetting the NVRAM, resetting the SMC, running disk utility and cleaning whatever I could clean through onyx, nothing worked.
I also updated to the latest security updates available.
When I boot on safe mode, VLC doesn’t want to play (I get a glitchy bit of screen and then nothing), and youtube seems to play the video fine but there is no audio output available . I am no specialist on safe booting, however… Is this normal ?
Can anyone please please help ? My knowledge on troubleshooting is pretty basic and I am really freaking out because I am supposed to start editing from a remote location on this computer next week .
My specs :
Apple MacBookPro 15 inch 2018 running Mac OS Mojave 10.14.6
2,9GHz Intel Core i9
32Go 2400MHz DDR4
Intel UHD Graphics 630 / Radeon Pro Vega 20
My 1To SSD hardrive is less than 50% full.
Thank you so much for your help and my apologies for the long post…
All the best from France
