Re: [Avid-L2] Mac Nvidia/CUDA drivers

 

That thread does discuss the problem that I was describing, that nVidia locks it's driver to specific OS builds, but not the solution I was remembering. 


First, I don't want to send you down a rabbit hole. I have not done this edit myself and I don't think that is your most likely problem. On the one occasion that I diagnosed this mismatch, I simply waited. It took about a month before Apple issued a new build and nVidia issued new drivers that matched. I mentioned this problem because the bad relationship between nVidia and Apple may result in terminal builds that are left in limbo forever.

I see that Message #64 in that thread describes changing the OS build to match the build the driver is looking for. That's backwards and seems dangerous. My memory is that it is possible to change the *driver's* files so that the driver believes it is compatible with that particular OS build. I was describing editing the driver's compatibility list, not the OS system information. This solution may be referenced in the thread somewhere but I did not see it. 

In that same thread are references to a variety of compatibility lists and ways of checking your driver versions against your specific system build. I would check all of these things first and only attempt the modification I referenced if there is a mismatch AND you don't expect nVidia to fix the mismatch. 

Remember that pretty much every significant Apple update changes your build number and these are frequent, so chances are good the problem will be fixed by Apple and nVidia at some point. 

Otherwise, the full uninstall and reinstall routine described in Message #86 is a better starting point. I have used this solution successfully on other occasions.

Cheers,

Thanks for this suggestion, Tod.  I'm not sure I've had much luck finding the fix you're referring to.


The closest I come is in this thread:

It talks about editing the SystemVersion.plist file, in order to spoof the Webdriver installer into installing on an unsupported build.  

Is that what you had in mind, or is this totally different. 

Thanks,
