I’ve saved about twenty 2011 15” MBP using this gem, it’s also free ;-)

To turn off the dual graphics capability of the GPU, install '''gfxCardStatus for Mac'''

Download  https://gfx.io

This will disable GPU switching and force the MacBook Pro to use the higher powered discrete graphics card rather than the integrated GPU.

# Go to the  Apple menu and choose “System Preferences” and then go to “Energy” control panel
# Uncheck the box next to “Automatic graphics switching”
# Note the text which states this may decrease battery life on the MacBook Pro “When automatic switching is disabled, your computer will always use high-performance graphics. This may decrease battery life.” – if you are not OK with that do not disable this option
# Close out of System Preferences
# You can always return to the Energy preference panel to re-enable the GPU switching feature if desired.
# For MacBook Pro users who want to '''manually control their GPU use''', you can use a third party tool like '''GFXCardStatus''' which has been around for quite some time and still works on most modern MacBook Pro models as well.
