Do you have an old iPhone, iPad or Mac sitting around? You can actually put it to good use as a second display. OpenDisplay lets you turn an iPhone, iPad or another Mac into a proper second monitor for your Mac. Instead of simply mirroring your screen, macOS treats the connected device as an additional display, so you can move windows onto it, arrange it alongside your main screen and extend your desktop. https://firethering.com/open-display-second-monitor/ #macOS #monitor #opensource #Utilities #iphone #iOS #tech
