    Hello all,

    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.

    I tried:

    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 .

    Thank you so much for your help and my apologies for the long post…

    All the best from France
