Macbook Pro 15" Mid 2012 Kernel panics

[lostregr123]

My machine starts after 2-3 tries and it works but I get this kernel panic when I work. Any idea or solution?

panic(cpu 2 caller 0xffffff7f926f23a1): "virtual bool IOAccelLegacyDisplayMachine::display_mode_did_change(uint32_t): vendor driver returns false"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOAcceleratorFamily_kexts/IOAcceleratorFamily-438.7.3/Kext2/IOAccelLegacyDisplayMachine.cpp:267

If I understand this correctly, it seems like a GPU failure.

The most likely cause for a Kernel Panic issue in macOS is faulty software, damaged or incompatible hardware, including external drives attached to the Mac. To fix the issue, try the below steps:

1. Restart your Mac in Safe Mode and check for updates.
2. Uninstall any plug-ins or 3rd party software from manufacturers other than Apple.
3. Disconnect all connected devices.
4. Use Apple diagnostics to diagnose the problem.
5. Reset PRAM/NVRAM settings
6. Reset SMC (System Management Controller) settings
7. Reset the GPU (Graphics Processing Unit)

Hope it helps!
