![]() I just installed your app, and am at home, unable to test it fully. As far as I can tell, the app does permit power-source-based switching without the login display resolution problem! I have to test the effects on an external projector display next week when I'm in a classroom, however it may limit the resolution available to me when running on battery power and connecting a projector. This application allows me to choose the card to use when I want to save battery power and have no external display connected.īut it resets automatic switching if it was turned off before the app was run. This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. You can't get back the highest resolution and have black bars at the top and bottom of the screen (the higher resolution setting is not available on the integrated card, and for some reason the system won't permit the change). If you need to force Integrated, shut down ALL VMs, set gfxCardStatus to Integrated Only, then start Parallels or Fusion.On some Macs with dual cards, such as my 2011 MBP, use of the Energy Saver automatic graphics switching will trigger a display problem when logging out and logging back in: the display will be stuck on a lower-resolution option until restart. I have read that for both Parallels and Fusion, you need to force Integrated graphics before you start the app – not just before you start a VM.If you set 3D off, (Parallels says) you need only 32MB of video memory.Options/Optimization/Power = Longer Battery Life.Edit each Parallels VM and configure it as follows (to prevent Parallels from overriding gfxCardStatus and setting Discrete mode).Install gfxCardStatus 2.3 and set it to Integrated.I like OS X, but hardware failure has to be part of my planning since it just happened. If I were using a Windows PC, I’d be creating a P2V (physical to virtual) backup on a weekly basis, and I could pick up where I left off on any machine that runs VMware, by copying my VM there. This whole episode has left me feeling vulnerable to hardware failure. In the meantime, I have to get by with this laptop, so here’s where I’ll capture the tweaks to prevent use of the discrete graphics card. I am on Yosemite 10.10.1 I also have FileVault enabled, so I am seeing the broken discrete graphics right from the start when I am prompted for my password, long before any driver from hard dis can. I expect a $2000+ computer to last much longer. The latest release (2.3) of gfxCardStatus displays a message if trying to switch to Integrated Only and either an external monitor is attached or an app that requires discrete graphics is running as in the image below. gfxcardstatus 2.3 complains it cant switch to internal graphics because there is an external display connected (not true), 2.2.1 just doesnt work. That would be OK except I’d be out of service for about a week, and I have to deal with packing and shipping it, and it might get ruined.įor now, I’m trying to live with it. I could send it off to have it “ reballed” for about $200. ![]() Download gfxCardStatus gfxCardStatus 2.3 983 KB Freeware OS X. If I activate the chip, the Mac crashes within a few minutes. VNC client allows remote access to another computer over the network. At this point, I can use my MacBook only if I never activate the discrete graphics chip. Of course, it happened a few months after my AppleCare expired, when my MacBook was just over 3 years old. ![]() ![]() I’m one of the people who has been hit by the solder problem on the GPU see.
