When I pointed out the whole "NVIDEA-MACBOOK PRO SAGA" genius bar member ( she was nice and empathetic) said to me that the problem with my GRAPHICS CARD was not the same problem. Today I get a call advising me that their diagnostic test LO AND BEHOLD highlighted that their "GRAPHICS CARD" ( Nvidea ) had failed. Yesterday when I rang them again, I was advised that they were running more tests to make sure it was the Logic Board. Initially they said that I could not get this by email. I wanted to find out the exact details of what's wrong with the Logic Board and waited to hear from them for two days. On Monday the Apple store informed me it was my Logic Board.

It has lasted just 1.5 years and as a student I just don't have the funds to get this fixed (could probably get a decent PC for that money). Instead, I get an email advising me that I have to physically go to the store to get the technical details of the fault.This is so disappointing. I wanted the technical details of the fault emailed to me so I could get a second opinion. Today I was advised by a store personnel that it was a "Logic Board " fault and had to be replaced (costs approx 400GBP). This time I was advised that the technicians would run a detailed diagnostic test and they suspected that it was a Logic Board or RAM issue. But it wasn't the case and I had to travel to go again. I was advised to delete Sophos and everything would be fine. I recently took it to Genius Bar in UK and was advised it was a 3rd party conflict (Sophos anti-virus) issue. However, after not bothering with it for many hours (busy with work) I would be able to turn the machine on and use it for 5-15mins and would experience another kernel panic. Started getting kernel panics recently and after every panic attack the machine would beep 3 times repeatedly. No problem.ħ - Open Console.app, type into search: gfx0 and check if g-state changes if working!ĪppleGraphicsPowerManagement.kext 10.11.I purchased my Macbook pro 1.5 years ago in Aug 2010 (did not purchase Apple care for extended warranty).
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).

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?).
