Meanwhile I'm gonna look and find myself a second hand 2012 mbp that apparently have better parts and can take me into the sunset for another few years. , that is until the next logic board disaster waiting to happen on this model. The bad news is that I know I am on borrowed time. I frigging hate the feel and look (not to mention the sadistic real life beta-testing Apple inflicts on us lately, especially with El Capitan) of the "new and improved" OSes and lack of backward compatibility of the new machines with Snow Leopard. The good news is that for $500 I have a working mbp that hopefully is going to last a while, I really don't want to give up on SL (10.6.8) - it is the most stable OS Apple has released to date. The seller screwed up his description post online. I stand corrected on the replaceable GPU on this board - it cannot be done. I highly recommend them for parts and spares. I finally got a working MB, a new battery and new fans for about USD 500, shipping included. it is quite the mess they've created! Using more than actually needed. Since I had the logic board out of the laptop enclosure, I decided to clean and replace all the original thermal paste that Apple applied. just don't mind the language used! I used a Panasonic Aluminum Polymer Capacitor (. The solution is to replace the bad capacitor with a better part! Louis Rossmann recommended using Aluminum Polymer capacitor because they are highly reliable! Here is the link to his video ( ). Solution was to replace the bad tantalum capacitor not just with a similar part! If you do that, you'll end up with the same issue later down the road. Because the bad capacitor can't handle the voltage anymore, it cause the GPU Panic. When the dGPU is running at high performance settings, it requires a lot more voltage. Results from my research, the issue is the Tantalum capacitor used to regulate power to the dGPU. The downside of this downside is that your battery life will suffer considerably if you run with the dGPU enabled all the time.

It won't automatically switch to the dGPU just for mission control. I did a lot of research on this issue when my MBP started to crash (GPU Panic) 5-6 times a day. The downside is that you have to be running an application that forces the system to switch to the dGPU (or run gfxcardstatus). There are a lot of reports with regards to Apple previously replacing the boards and after a little while, the problem reappears. I will ask over at FreeMind what can be done.My MacbookPro6,2 was experiencing GPU Panics. As soon as you want to open/create a new file, the creation of a window fails: Short flash and the main menu (the application stub I guess) re-renders shortly. But you then only see the main menu (the application stub I guess). You see the startup dialog ("Freemind 1.0.1": Initializing this, that, bla bla) until the app is ready. Removing JVMRuntime=jdk1.7.0_45.jdk starts the app with the iGPU indeed but then does not work. Jdiskreport 1.4.1: After having added NSSupportsAutomaticGraphicsSwitching=TRUE to the ist it then launches with the internal GPU and functions normally!įreeMind 1.0.1: ist was shipped with NSSupportsAutomaticGraphicsSwitching=TRUE and NSHighResolutionCapable=TRUE. Setting NSSupportsAutomaticGraphicsSwitching to TRUE indeed prevents the enforced use of discrete GPU usage! But not for all Java apps! I tested these: Update as of : The newest generally available macOS + Java today is: Unfortunately this option is not included in the standard JVM distribution from Oracle.

Otherwise the system uses the discrete graphics by default. This gives a Java application the power of using the integrated card. There is a special option which has to be specified in the ist file of the launcher of the application: NSSupportsAutomaticGraphicsSwitching
