Copying my question from apple discussions where an answer couldn't be found.

After upgrading to 10.15 my MacBook started crashing frequently, especially when under higher load (5 or more browser tabs or a video game open) and more often when the charger is connected. Any advice on how to fix this?

If it crashes and I start the laptop again straight away I get the Apple logo with the bar going about 3/4 way through after that I get black screen with laptop still running (fans can be heard). If I let it rest for about 10 minutes it comes back on fine and can work for a long time unless, again it is put under higher load.

Also, when I brought my MacBook to the Genius Bar they said they couldn't do anything as it as a 'vintage' model now, and the guys on the Apple web chat support implicitly recommended getting a new MacBook.

Hardware diagnostics found no faults. Issue occurs also in safe mode. The OS has been reinstalled 3 times from scratch and the issue persists

    You may want to let the "Geniuses" know that Vintage products are still supported and are not obsolete. See: support.apple.com/en-us/HT201624

  • Was this an in-place upgrade or a clean install of Catalina? In other words, did you wipe your drive clean before installing Catalina then do a data migration from Time Machine or did you just click upgrade and install over what was already existing?

  • Hi, thanks for your reply. I performed a clean installation several times.. I also manually erased the disk using disk utility

  • Does the problem go away if you install 10.14?

  • How does this occur in safe mode? I mean, how are you even able to reproduce it given that I thought the discrete GPU drivers aren’t even loaded in safe mode? Also, do you mean at home hardware diagnostics checked out or Apple’s in house diagnostics when you took it in?

Apple's laptops with discrete graphics units do not have a great track record. However, it may be that the OS you updated to has different drivers, or makes more demands on the GPU, which causes some kind of problem (a GPU panic in this case).

If one clean install doesn't fix it, then don't do another. You could try reinstalling the previous OS: if everything works, then stay on that OS for the remainder of this laptop's life. If it doesn't, then you know it's not the software, and age or misfortune has caused some hardware problem.

Fixing hardware problems will not be cheap, and I would recommend putting that money towards a newer Mac instead. 8 years is not a bad innings for a laptop.
