You cannot use this method to turn on your MBP on a daily basis but it is a good troubleshooting technique. No problem.ħ - Open Console.app, type into search: gfx0 and check if g-state changes if working!ĪppleGraphicsPowerManagement.kext 10.11.If the keyboard failed (let’s say you spilled liquid on it) and the power button stopped working there is a workaround for turning it on. Maybe smc is responsible.Īfter osx loading i can change to discrete cpu only or in automatic graphics switching. Discrete gpu only (automatic graphics switching unselected) not working properly, and, i don't know why. Here, in my tests is important every boot must be in automatic mode. Remember, the option automatic graphics switching selected always. You can check this on: About System Information -> Extensions) (make sure the AppleGraphicsPowerManagement.kext is loaded. SIP is important to safety, but, we are good guys, we'll know to keep the system safe!ģ - Open Extensions folder (System/Library/Extensions), copy AppleGraphicsPowerManagement.kext to desktop (or other folder), open the ist into editor (I used the PlistEdit Pro.app), and change the values like writing up.Īttention: verify if your model is 0x0a29 really.ĥ - 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.Ħ - (This is important step) Leave the automatic graphics switching select (System Preferences - Energy Saver), if you are using gfxCardStatus.app, same thing!. You can check this on: About System Information -> ExtensionsĢ - Disable SIP (boot into recovery mode, terminal: csrutil disable) ACPI_SMC_PlatformPlugin.kext (IOPlatformPluginFamily.kext).
#2010 macbook pro 13 inch can i run transistor mods#
Only so.ġ - 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): Perfect values? I do not know, but it is working for me.
(attention: only try this if you really have the problem gpu panic). If you want to try, these are the values changed in the ist: Not bad.īattery consumption does not change much. 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.Īnd the performance? Exemple: Cinebench, default (G-state 0) i've about 15fps, with g-state 2 (medium speed): 10fps.). G-state 0 (maximum speed) and G-state 3 (lowest speed). Are related to the thresholds inside AppleGraphicsPowerManagement.kext, like this: This is to maximize performance and battery consumption. G-States go from 0 to 3, are related to the gpu use (idle/load). 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. I discovered that this problem happens every time that g-state change between 2 to 0 (or 2 to 1). I have the famous MacBook Pro 6,2 with GT330m (0x0a29 model). Well, after years i found a solution (so mine?).
