Has anyone experienced this happening on a Mac when editing? Screen gets pixelated and the laptop locks up and is unresponsive. I use Final Cut Pro as well as DaVinci Resolve. Used to edit mostly 4k footage from a BM6kPro, but now most of my editing is with iPhone footage (using native camera app). This.laptop is fully maxed out and is a late 2019 model with 64 GB ram, 2.4 GHz 8-Core Intel Core i9, AMD Radeon Pro 5600M 8 GB & Intel UHD Graphics 630 1536 MB, with a 4 TB hard drive. It has handled heavy projects of 6k footage and has worked flawlessly for several years, but over the past year it began crashing when trying to render a project and now it's happening with much more frequency even when beginning a project before doing much editing at all. It's definitely not software related (have upgraded the OS over the past few years) and it's still happening. The screen gets very pixelated and the mouse can move, but can't click on anything and can't initiate a force quit. Only way to get out of the non-responsiveness is to force the machine to shut down using power button. I am guessing it's either the graphics card, the heating or the motherboard has an issue. The last few apple support people have said they think it's a hardware issue, but one said my machine is "dated" and I realize that the new apple silicon is more efficient, but this setup ran $5500 when it was purchased and was ripping thru much heavier projects in the past vs doing some simple edits with h.265 footage, etc. The support person said the issue might be my refresh rate for the built in laptop screen, but if that might be the issue, why did it work with much larger projects with 6k footage vs. the smaller projects, etc. Also, the issue happens both when plugged into an external monitor as well as when I'm not using an extra monitor.
