If you have faulty MacBook Pro 2011 15" or 17" which does not boot properly, we can fix it for you. All that you need is to send or bring it to us. What we will do is completely disable discrete AMD graphic card and MacBook keeps working as normal with an Intel HD 3000 graphic card.

This fix is permanent and won't be cancelled by replacing a hard drive, upgrading RAM, reinstalling OS or resetting PRAM or NVRAM!!!

It will not affect your data or passwords.

The only two things will be affected:

1. You won't be able to use the Thunderbolt port to connect the external screen. However, you can use the thunderbolt  port to connecting eGPU enclose which will improve performance a lot (please see photos)

​

2. To adjust the brightness of the screen you will need to use a free app ( I setup Fn+F1 and Fn+F2 for changing brightness)
