Stephane, The Mac on which I've been seeing the applicationDidChangeScreenParameters: delegate method triggered is a Late 2013 Mac Pro. Per Apple Technical Note TN2335 <https://developer.apple.com/library/mac/technotes/tn2335/_index.html>, it can switch GPUs. However, the gfxCardStatus website <https://gfx.io> says it is for MacBook Pros. I've downloaded it but won't be able to try it out until later. Do you happen to know if it works on the latest Mac Pros as well as MacBook Pros? I also have a Late 2013 MacBook Pro on which I can presumably use gfxCardStatus. -- Bill Cheeseman - b...@cheeseman.name _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
