If your getting that message seems you are using old machine of Mac with Snow Leopard and Time has come to purchase new one or if possible upgrade to OS X High Sierra. I just installed your app, and am at home, unable to test it fully. Answer (1 of 2): The point is How old is your mac Machine and it’s software. As far as I can tell, the app does permit power-source-based switching without the login display resolution problem! I have to test the effects on an external projector display next week when I'm in a classroom, however it may limit the resolution available to me when running on battery power and connecting a projector. This application allows me to choose the card to use when I want to save battery power and have no external display connected.īut it resets automatic switching if it was turned off before the app was run.
STUCK WITH 10.6.8 SOFTWARE UPDATE
This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. You have no idea how frustrating this is, especially with all the time I. Now i find there is no way to upgrade because i cannot download any of the newer systems. You can't get back the highest resolution and have black bars at the top and bottom of the screen (the higher resolution setting is not available on the integrated card, and for some reason the system won't permit the change). i finally got my snow leopard 10.6.8 installed in what seemed like forever, hoping i could upgrade to a newer operating system.
On some Macs with dual cards, such as my 2011 MBP, use of the Energy Saver automatic graphics switching will trigger a display problem when logging out and logging back in: the display will be stuck on a lower-resolution option until restart.
