Hi everybody ! Can someone tell me if the screen resolution is fixed at boot or is it supposed to scale to my deskop screen preference ? When I start my rMBP 15" 2015, the loading bar start with a 1440x900 resolution, then halfway the screen flash briefly and the loading bar continue at my chosen resolution (1680x1050). I have tried a lot of thing to fix it without any luck (reset PRAM/SMC, reinstall, clean install, changing resolution in root mode, safe boot, etc) Any idea ? Maybe it's normal but in my 13" rMBP 2015 also set with a scaled resolution it boot without any problem. Thanks !
