![]() Go to the stylized i in the upper menu bar, click on it, and see that it points to the "integrated only" option. Next: Verify the gfxCardStatus app settings. This is as it should be.Ġ6 Reboot into the SSD/HD that was taken from failing 2011 MBP. Now the screen has two check marked items, one grayed out, one not. Where it says Plugged In: Select Integrated. Where it says On Battery: Select Integrated. Next: click on Advanced, Now, check mark the 1st & 2nd items. Next: click on General, then check mark the 1st, 3rd, & 4th items only. You may have to reboot into the SSD/HD again before you can configure the app.Ġ5 Go to the upper menu bar to the stylized i. You can connect to an iMac or other Mac Desktop as well.Ġ3 Boot into the SSD/HD that was taken from the failing 2011 MBP.Ġ4 Install gfxCardStatus 2.1 into the bootable SSD/HD that was taken from failing 2011 MBP. Or, with the SSD/HD still inside the errant 2011 MBP connect it to a working 2011 MBP via FireWire or Thunderbolt cable, using Target Disk Mode. Either remove it from the MBP, and USB it to another working 2011 MacBook Pro. You may download the file from my DropBox site here: (Click on the DOWNLOAD Button on the upper right side of the screen.) Ġ2 About the SSD/HD in the failing 2011 MBP. On a working Mac, download GFXCardStatus version 2.1. For the “Work-A-Round” to consistently work, SIP needs to remain inactive.Ġ1 Get the software. Launch the Terminal from the upper menu bar. Hold down Command-R key combinations on the keyboard immediately after pressing the power button to turn on the MBP, or immediately after the MBP begins to restart. SIP protects files, directories, and processes at the root level from being modified.) To disable SIP, Boot into the Recovery Drive. (Apple says, SIP stands for System Integrity Protection (SIP). I recommend you replace the battery before undertaking this project.Ġ0 SIP must be disabled before making the changes noted below. If your MBP has been “down” for some time due to this problem, there is a chance the internal battery is either drained completely, or will otherwise not function as a “good working Battery.” A battery in this condition, will not allow your MBP to boot up, even if the AC Adapter is connected and plugged in. ASSUMING THE DUAL GFX CARD IS IN FACT YOUR MBP’S ISSUE, properly done, your MBP will boot normally using the Integrated GPU and run quite well. Once configured, reboot the computer.īe patient. Once in, open the app and configure it per directions found later in this document. Once installed, boot the computer in safe mode (this assumes the Discrete GPU has already failed), this boots the Integrated GPU. The 13" Model is not affected by this problem. This applies to the 15 or 17 inch model, created early or late in 2011. Install an application (App) called GFXCardStatus, Version 2.1 into your 2011 MacBook Pro's Application Folder. SIP must be disabled before making the changes noted below. This work around does not involve running Linux, or Windows. It also turns off the GPU automatic switching capability. The “Discrete GPU” is what has or will fail. This procedure if successfully implemented forces the “Integrated Only GPU” into operation, and does not allow the “Discrete GPU” to function. ![]() I'll likely be running Windows 7 (or XP if it proves a better option for extending the battery) and Linux running in WMware.I have found and tested a successful work-a-round, for 2011 MacBook Pros with the known Dual Graphics Processor failure problem. Ideally, it should be very thin (no optical drive), screen size does not matter but the smaller the better, a respectable battery life, and the most important attribute, low heat generation meaning no quad core/dedicated gpu setup. With my fears of excessive heat build-up having been confirmed, I'm now in the market for an expendable netbook that can do the job but without cooking itself while operating inside a backpack (or at least minimize the possibility). Fortunately, I was provided with a replacement system courtesy of Applecare warranty. ![]() I've taken up an interest in war walking (I don't own a vehicle) and in an effort to stay stealthy, I've opted to go the "laptop in a backpack" route.Īs an experiment, I warwalked with an Alfa AWUS036H attached to a Macbook Pro operating in a backpack (running snow leopard with linux in wmware fusion) and while the tests were highly successful, my Macbook Pro soon became a casualty of excessive heat despite assigning 1 core to the Linux virtual machine and a forced integrated gpu setting via the gfxCardStatus app. ![]()
