Editing a a dump of CoreBrightness.frameworks/CoreBrightness macOS 10.12

2007 iMac that is running macOS 10.12. Im trying to gain some functionality that isn't supported on my iMac. I got the offset for Macs that are supported for Night Shift by doing this

And then got a dump of the data by doing this

So now I'm looking at the data and found the location and "0d" is for iMac13,1. So naturally I changed it to hex "07" meaning iMac7,1. And now it would look for my year iMac as a compatible one. That didn't work. Now System Preferences crashing as soon as I click on the Display Preferences.
The highlighted hex is the place I am editing.

And I am providing the crash reports in a zip file if anyone wants to look at them and see what else I might have to do

The problem with CoreBrightness is that it exclusively uses Metal. If your GPU doesn't support Metal, you're out of luck.

I do have night shift working on my 2007 iMac with the ati Radeon 2400 XT (doesn't support metal or night shift) by using clover boot loader and a smbios that makes my iMac think it is a late 2013 model iMac (that does support metal and night shift natively)
But I'm trying to get it to work without using all that

I had to re-sign the patched framework binary and that solved the problem with Display Preferences crashing. I now have Night Shift working natively on an unsupported 10 year old iMac!
