Video Card swap

Hi there,

I know this is a bizarre question but my MBP 15" is quite close to pull the bucket and while a wait for a new machine, when I'm around I'm trying to work with it. The problem is that the graphic chip (AMD) isn't working properly anymore so with a lil app I'm forcing to use the Intel graphic for almost everything. But every time I launch Musescore it swap from Intel to AMD and 90% of the time the machine die.

Apart non using Musescore on this MBP, is there anyone with a solution?

Best
