Thanks for your work. On both my MacBook 6,1 and MacBookPro 5,1 using the GeForce 9400M sometimes videos on FaceBook or YouTube will not play. Would your script fix this?I have a MacBook6,1, with SSD and 8Gb RAM, and I successfully updated it from High Sierra to 10.14.3 thanks to the dosdude patcher. Thank you very much. Everything works as well as on High Sierra. The problem of artifacts of the light theme was safely solved by the transutil script.
Macbook 6.1 uses hardware video decoding through 9400m. This reduces the heating of the processor and unloads it by 2 times when watching FullHD movies. Some videos recorded with the iPhone began to occur jerks and friezes, which were not on the High Sierra. I was able to fix this problem by taking AppleGVA.framework from High Sierra (17G5019) and replacing it with a system one. And then updated the script cache. After the reboot, the jerks stopped. Everything now plays smoothly, as well as in High Sierra.

I wrote to share this decision, it may be useful to someone. For myself, I wrote a script to make the substitution of AppleGVA.framework quick and easy. The script is trusted on my macbook. It contains AppleGVA.framework from High Sierra. No need to search. There are even two scripts. The second script restores the state of the system before the patch. This is in case you don’t like the result. Sorry for my English. Thanks.
Cheers
