How can I fix my Mac Pro 2019 mouse and keyboard issues?

Mac Pro 2019 startsup but mouse, keyboard are not functioning. Plus the setup screen displays briefly only to be replaced with 'digital snow'. Any solutions?

Hi,

What happen if you start up in Safe Mode? If it doesn't fully boot up, try to run Apple Diagnostics if it reports hardware error.

Start up your Mac in safe mode – Apple Support (AU)

Use Apple Diagnostics to test your Mac – Apple Support (AU)

If your Mac doesn't start up all the way – Apple Support (AU)

"digital snow' is very rare when you have a WORKING graphics card.

Many thanks for your replies.

I’m as certain as I can be but I’ve narrowed the fault down to a loose fitting HDMI cable in the rear of the MacPro 2019. I think maybe the socket itself has become a little enlarged with use.

Im currently transferring close to 4 TBs of Photos from an HDD to an NVME. Should have left this to run over night, it will take over four hours to complete!

Thanks again.
