#Monitorcontrol mac m1 pro

Snowy forests in Răcădău (Braşov, Romania)īut I was fortunate, as I had my trusty 2019 MacBook Pro to keep my hands warm while I was cranking code that will be obsolete in less than 6 months on my day job. Days were cold and less than 10km away from my place you could take a walk through snowy forests. Io_service_t framebuffer = 0 CGSServiceForDisplayNumber ( displayID, & framebuffer ) io_service_t interface if ( IOFBCopyI2CInterfaceForBus ( framebuffer, bus ++, & interface ) != KERN_SUCCESS ) return IOI2CConnectRef connect if ( IOI2CInterfaceOpen ( interface, kNilOptions, & connect ) = KERN_SUCCESS ) IOObjectRelease ( interface ) Without analytics, I had no idea that Lunar had so many active users! # Constructing the DDC request

The previous APIs weren’t working anymore on the M1 GPU, the IOFramebuffer was now an IOMobileFramebuffer and the IOI2C* functions weren’t doing anything.Īll of a sudden, I was getting countless emails, Twitter DMs and GitHub issues about how Lunar doesn’t work anymore on macOS Big Sur (most M1 users were thinking the OS upgrade was causing this, disregarding the fact that they’re now using hardware and firmware that was never before seen on the Mac) M1 Macs came with a different kernel, very similar to the iOS one. On Intel Macs this worked really well because macOS had some private APIs to find the framebuffer of a monitor, send data to it through I☬, and best of all, someone has already done the hard part in figuring this out in this ddcctl utility. I develop an app called Lunar that can adjust the real brightness, contrast and volume of monitors by sending DDC commands through the Mac GPU. # Adjusting monitor brightness on Intel Macs This is a story about how getting an M1 made me quit my job, bang my head against numerous walls to figure out monitor support for it and turn an open source app into something that I can really live off without needing a “real job”. This already starts to sound like those happy stories about seeing how awesome M1 is, but it’s far from that. So I got it! With long delays and convoluted delivery schemes because living in a country like Romania means incredibly high prices on everything Apple. I also had the excuse that users of my app couldn’t control their monitor brightness anymore, so I could justify the expense easily in my head. One lazy evening in November 2020, I watched how Tim Cook announced a fanless MacBook Air with a CPU faster than the latest 16 inch MacBook, while my work-provided 15 inch 2019 MacBook Pro was slowly frying my lap and annoying my wife with its constant fan noise.
