Developers now have access to Catalina

Recommended Posts

Sim fantomas, a Install eu já fiz desde o primeiro dia, tanto com a HD5770, quanto com a intelHD3000 e já tinha visto as duas partições, o difícil é fazer subir com aceleração essas duas graphics sem suporte ao metal, nem sem aceleração elas sobe. No 10.14, a HD5770 subia, mas sem aceleração, a intelHD3000 subia no 10.14 com aceleração (conforme imagens já postadas aqui), colocando kexts antigas e frameworks antigos, mas agora, o Catalina não dá nem suporte a isso mais, vou tentando aqui, Abraço.

It's still too early to determine what will work and what will not. We are currently discovering the changes in macOS Catalina and how they're working. It takes some times to figurate it out and deploy the patchwork or whatever.

Beleza, valeu, André.

 

 

EDIT.: tentei subir o Catalina com o opencore e nada também, nem sem gráfica

Alright, so for those who were wondering, myself and @parrotgeek1 have been working on this acceleration issue on our own, and have come to the conclusion that it is not going to be possible to achieve graphics acceleration on non-Metal video cards in Catalina. This is for various reasons, but the main one is the SkyLight and CoreDisplay dependencies. In Catalina, SkyLight and CoreDisplay have been changed greatly, and are interdependent on each other. Meaning, if you replace one from an older version of macOS, you must replace the other, otherwise you'll be left with a ton of unresolved symbols. The problem with doing this, though, Catalina's AppKit relies on all the new functions present in the Catalina CoreDisplay framework. You cannot use a copy of AppKit from an older macOS version, without causing a ton more unresolved symbols.

TLDR, based on this analysis, non-Metal GPU acceleration is not, and will not be possible on 10.15 Catalina. With that said, I will not be releasing the "usual" patcher for 10.15. I do not believe the general public should be using a copy of macOS without full graphics acceleration (I sure as heck know I wouldn't want to), and I'm not going to release a patch that results in extremely poor system performance for the end user (not to mention I would get thousands of complaints per day about it if I did).

I will, however, more than likely make somewhat of a "cut down" patch, designed for use only on Mac Pro systems and some iMacs that have had their video cards upgraded.

I'm as disappointed as you all are about this discovery, and deeply apologize I won't be able to provide a patcher because of it.

 

bom, acredito que uma das grandes vertentes deu uma desanimada, André.

Be aware that macOS Catalina is supporting APFS only!!! No more support for HFS+, nor MBR.

 

Maybe we'll see a workaround in near future, not sure.

 

Didn't test it yet but it may be a solution (credits to fusion71au)
