1 month ago I returned back to OSX, buy a macbook retina late 2013, as always mainstage for live use. Unfortunately I found CPU consumption problems, was using EL CAPITAN, did downgrade and the same.
I started mulling over what could be and those things run mainstage low resolution, which was the surprise, down from 45% to 24% consumption. Perform several tests and returned to launch mainstage normally, to touch and change patch comes several times to 100%. Again run in low resolution, perform the same tests and hopefully CPU consumption reached 60%.
Accordingly, apple has a bug with handling the GUI in mainstage, so running low resolution "fix" part of the problem of consumption.
As is done:
1. Go to the Applications folder
2. Right click on the icon mainstage
3. Select "information obtained"
4. Mark "open in low resolution" box
To enjoy.
