Crash on 1st startup

I haven't been able to open Resolve with old 12,1 Mac, Sequoia booted with Opencore Legacy. I know my GPU is OpenGL so I downloaded Resolve 18 that supports that in the specs.

I see in other posts the Dwaine recommends Resolve 16 for old GPU challenges.
Looking for advice.

Attached are computer specs and tgz log file

I installed Resolve 16 Studio and it works. Could someone please explain why Resolve 18 does not work with my hardware. Details provided in my first post.

Thank You
Jim

Your GPU only has OpenCL 1.1 support. Resolve 18 requires OpenCL 1.2 or better support.

Dwaine,
I very much appreciate your information on the Open GL and my old computer. Are you saying my graphic card hardware can't support Open GL 1.2. Or is it a driver version issue?

Thanks
Jim

Your GPU hardware does not support OpenCL 1.2.

It's not a driver thing.

Thank you.
Very helpful!

So my magic question is what really is the optimal system configuration to support R20 (and even R19 if i back down to lose the AI features)?

My current configuration is below and it worked fine for 16, 17, and 18 studio versions. It started chocking on itself a little bit on 19 studio in terms of timeline playback with nested compound clips and fusion-based graphics and magic mask and all that, But R20 has become basically unusable for me and some AI Features will just not work. Trying to do an AI Mask on a 22 second clip would have taken over 31 minutes!

I took a project over to a friend's house that had 20 studio installed and the timeline playback issue got better on their Mac Mini 2 Pro, but still not perfect.

Bein retired and on a fixed income, I don't have the $5-$6K to buy the machines recommended by BlackMagic or others, especially without road testing it first. That being said, what are my best options here? A power hungry eGPU? Stepped up laptop?

Thanks!

Hi,

Looking at this: https://www.techpowerup.com/gpu-specs/t1000.c3797
your card supports OpenCL up to 3.0, so that should be fine.

But..... The card only has 4Gb of RAM, so that will be the limiting factor here.
I know it will work, but it will slow things down when it gets slightly more complicated, as you have experienced.

It might be an idea to see if you can grab a 2nd hand 3060 or alike with 12Gb of RAM to 'keep going' for a while longer on your current setup? Or something with 8 Gb?

Can this be set up as an eGPU somehow? No way to add it to laptop...

I think eGPUs are a dead issue in 2025. There's a point where you have to abandon old hardware and get new hardware to replace it, especially if you're using modern software and OS's and a 2018 Mac Laptop. I'd say 7 years is the practical limit for Macs, unless you stick with the software available during that machine's lifespan (like Resolve 16 or 17).

Can you expand on this thought and what you mean?

Thanks!

Since your P53 has a Thunderbolt 3 port, you could theoretically add a better NVIDIA GPU via a PCI-e Thunderbolt 3 chassis. Not sure the performance would be much better than your T1000, but you could certainly add a GPU with more than 4GB of VRAM, which could be helpful if you need to work with more than HD timelines.

If you go that route, in Resolve Preferences - System - Memory and GPU area, you'd want to manually select just the TB3 GPU and not also use the T1000 GPU.
