2012 MacBook Pro a1398 Mojave

[j4jes]

Hi I'm using GFXCardStatus v2.4.3i and it works great when in integrated only (Intel HD 4000), but certain programs will trigger discrete or dynamic switching then crash to an unresponsive black screen where I hear the fan . The worst part about this is sometimes I think the MacBook is off but the fan is still throwing heat, then I'll put it it in my backpack and risk completely melting the motherboard and cpu!

How do I get integrated only, to stay on integrated only? The advanced preferences say switching has been removed but my MacBook is always switching. I don't want switching! Is there a hardware hack for this model A1398 that can save my MacBook without having to downgrade to an ancient MacOS release? Mojave is better then Catalina, since Catalina was a very bad experience.. I thought my MacBook was completely totalled, it crashed on every login screen. How can the drivers for the Geforce GT650m be so horrible in Mojave, High Sierra, and Catalina? Can I use some Hackintosh driver "kexts" instead? I wish I could just remove this Nvidia chip because otherwise this MacBook has been rock solid for eight years.
