I've got issues with my MBP which seem to be persistent, even after replacing the logic board for supposedly one without hardware issues. There are some typical instances when my macbook pro fails (crashes):

  1. After waking up and I open up an app, e.g. Chrome and start typing in the search/location bar.

  2. Just randomly (less so) and often in Chrome when I open up a page or Google something.

In addition, my battery was replaced twice and again it shows Service battery and has issues - e.g. a sudden drop in the percentage from 45% to 7% and overall short battery life.

Can anyone discover anything that could lead to a solution to this problem in the panic report below? My hunch is the graphics card or logic board or both..

I see from your panic report that this is a mid-2010 15" MacBook Pro. Unfortunately, this model was prone to having problems with its dedicated graphics card and while Apple did have an extended repair program for this model, that extra coverage has now ended.

However, there are a few things you can do to minimise the problem.


Many users have found that using gfxCardStatus will reduce these issues most of the time. My experience with many users is that versions 1.8.1 and 2.1 seem to be the best for your particular model MBP, even though more recent versions fixed a number of bugs.

So, I’d like you to give version 1.8.1 a go for a while and see how you go. If you’re not happy with that, then try version 2.1 instead.

NOTE: Unfortunately, there were two distinct issues that affected your particular model of MBP. gfxCardStatus was designed to address a hardware problem that occurs on a number of models, including yours. However, your model was also prone to being affected by a software issue that was unique to your model. If your model is affected by that as well, then version 2.3 may be a better choice. So, in summary, I would start with 1.8.1 and see how you go. If you’re not happy, then try 2.1. Then go to 2.3 if you're still not satisfied. Do not try any other versions for your model MBP!

Google Chrome

I actually wouldn't use Google Chrome on this machine, but if you really need to then there’s actually a setting in Google Chrome that may help you:

  1. Go to Chrome > Preferences
  2. Scroll down to the bottom
  3. Click on Advanced
  4. Scroll down to the System heading
  5. Disable the Use hardware acceleration when available option


There are a couple of things you can do within macOS:

  • You’re probably already aware of this one – but for your MBP you should have an additional setting under System Preferences > Energy Saver for Automatic graphics switching. Playing with this and the other Graphics option (for better battery life) may be useful.
  • Now this one is not so obvious:

    1. Go to System Preferences
    2. Click on Accessibility
    3. Select Display (in the left-hand column)
    4. On the right-hand side, tick the Reduce transparency and Reduce motion boxes.
    5. Exit System Preferences

Basically, to draw/display transparency and show motion in the GUI (windows etc), it needs a lot of graphics power. Not a good idea for your MBP I’m afraid.

  • thanks! one question: is the 'reduce transparency' box ticked on or off? I turned it off for now. Aug 12 '19 at 12:21

    You want to actually tick the box so that macOS reduces the use of transparency in its GUI.

  • I had 'Reduce motion' and 'Reduce transparency' both ticked on before, so that wasn't preventing the problem to occur unfortunately. Aug 12 '19 at 12:27

    By the way @ThiemeHennis , if your battery continues to have problems it’s most likely a totally separate issue. Your best bet would be to reset your SMC. See: support.apple.com/HT201295

    You want to avoid as much as possible the NVIDIA GPU being used, so my recommendation would be to use Intel only and to take the steps in my answer re Chrome etc.
