UPPERCASE GhostCover Premium Ultra Thin Keyboard Protector for MacBook Pro with Function Keys 13', NO Touch Bar (2016 2017 2018, Apple Model Number A1708). I have the famous MacBook Pro 6,2 with GT330m (0x0a29 model). I discovered that this problem happens every time that g-state change between 2 to 0 (or 2 to 1). The problem in the use of nvidia is not the gpu, but the stabilization of the voltage when the gpu changes from g-state 2 to 0 (or 2 to 1), causing the known issues.

Hello, Well, after years i found a solution (so mine?). I have the famous MacBook Pro 6,2 with GT330m (0x0a29 model).

I discovered that this problem happens every time that g-state change between 2 to 0 (or 2 to 1). The problem in the use of nvidia is not the gpu, but the stabilization of the voltage when the gpu changes from g-state 2 to 0 (or 2 to 1), causing the known issues. G-States go from 0 to 3, are related to the gpu use (idle/load).

This is to maximize performance and battery consumption. Are related to the thresholds inside AppleGraphicsPowerManagement.kext, like this: G-state 0 (maximum speed) and G-state 3 (lowest speed). I solved the problem by keeping it always at G-State 2 (medium speed), that the problem of stabilizing the voltage not compromise the gpu work. And the performance? Exemple: Cinebench, default (G-state 0) i've about 15fps, with g-state 2 (medium speed): 10fps.).

Avg cleaner for mac review. Battery consumption does not change much. If you want to try, these are the values changed in the info.plist: (attention: only try this if you really have the problem gpu panic).

I do not know, but it is working for me.

Step by step: 1 - Verify that the file is the original and this loaded (there are mods that remove these files) and if they are the original (Apple signed): • ACPI_SMC_PlatformPlugin.kext (IOPlatformPluginFamily.kext) • AppleGraphicsPowerManagement.kext You can check this on: About System Information -> Extensions 2 - Disable SIP (boot into recovery mode, terminal: csrutil disable) SIP is important to safety, but, we are good guys, we'll know to keep the system safe! 3 - Open Extensions folder (System/Library/Extensions), copy AppleGraphicsPowerManagement.kext to desktop (or other folder), open the info.plist into editor (I used the PlistEdit Pro.app), and change the values like writing up. Attention: verify if your model is 0x0a29 really. 4 - Save info.plist, quit editor. 5 - Use Kext Drop.app or Kext Utility.app (this is not marketing, okay?) Only to facilitate the process to instal this kext, but before, delete the AppleGraphicsPowerManagement.kext into extensions folder. 6 - (This is important step) Leave the automatic graphics switching select (System Preferences - Energy Saver), if you are using gfxCardStatus.app, same thing!
