It would not be normal with 8.1.1, but what exactly was your problem? The right third of the image being cut off as in the original post? Or not rendering at all?
Are you using an AMD/ATI GPU card?
What resolution files are you rendering?

This is related to using an ATI/AMD GPU card. This should be fixed in 8.1.1, or the new 8.2 release.

Can you try restarting your Mac to see if that makes the message go away?

Is the NR selection grayed out?
Lite does not support NR. Are you using the full version of Resolve?
Is there a display connected to the 4000 card?

If there is one (supported) graphics card in the Mac, Resolve is forced to use that for both GPU processing and GUI display driving. And you will get a warning message telling you this is not advised due to the performance hit. And it will display 1 GPU being used in “About DaVinci Resolve”. But it will work.
If there is more than one (supported) graphics card in the Mac, the card connected to the GUI display is NOT used for GPU processing. It’s only driving the GUI display. Leaving the other card(s) available for dedicated GPU only processing.
In Resolve Lite, if you have 2 cards, one is used for the GUI, and the other is used for GPU processing. If you have more than 2 cards, Resolve Lite will still only use 1 card for GPU processing. So you will always see 1 GPU in the “About DaVinci Resolve” dispaly in Lite, no matter how many cards you use. But having the second card for the GUI display leaves the 1 GPU card fully available for GPU only processing, so performance is better. So 2 cards is still recommended for Lite for best performance.
In full Resolve, the number of GPU’s shown in “About DaVinci Resolve” should match the total number of graphics cards in system, minus the one connected to the GUI display.

That assumes PostgreSQL is properly working.

Check in Windows Device Manager, and verify in the Display Adapters section that Windows actually sees all those cards properly. I would not be surprised if you see some yellow !’s there.

If you are not getting an error about the GPU being used to drive the GUI display, and you have no displays connected to the 4000 card, then the 4000 card is being used to do the GPU processing.
Yes, 1 GPU is correct for your system. The card connected to the GUI display (4800 in your case) is not used for GPU processing.
If you move your displays from the 4800 card to the 4000 card, then the 4800 card will be doing the GPU processing.
It might be curious to do that test, and see which card you think has the better performance in your system.

If you are getting NO CUDA errors, then Resolve will crash when you select a file on the Browse page.
Just to make sure it’s fully installed, now that you hopefully have the 256.02.25f01 driver installed, from the same Nvidia Driver Download site, in the Nvidia CUDA Driver for Mac section lower on the page, download and install the 4.0.50 CUDA driver, and see what that does.
If you still have issues after that, please run the Resolve CaptureLogs app, in the /Library/Application Support/Blackmagic Design/DaVinci Resolve folder. When you run this, it will create a .tgz file on your desktop. Send that, along with a .spx export of your Mac System Profile, to our davincihelp@blackmagic-design.com email address.

You should go to the Nvidia Driver Downloads site, and download and install the Quadro 4000 for Mac Nvidia driver for OSX 10.6.8, which is driver version 256.02.25f01.
