Has anyone who had the same problem for example gotten any success using a USB-C to HDMI adapter instead of a USB-C to DisplayPort adapter?

I do not even have a clue on how to begin that process, nor would I prefer not to lose any data again (I do not have an additional external drive).ĭoes anybody know of another solution? Because it is not really a possibility to just keep using an old OS. So even if it is possible, if something happens and I screw things up, then I am at fault I suppose. I called my local Apple's technical support number, and I was told that I am not able to downgrade because it was shipped with it.

Since using this new MacBook Pro with High Sierra on it, it simply acts as if my external monitor does not exist.ĭoes someone have any clue on what to do? Little tricks such as trying all USB-C ports, rebooting and reconnecting everything and booting in safe mode are to no use. I know for sure that the adapter works properly, as I have two of them which both worked before. Normally it automatically detects a source and switches to that mode, but I also tried manually switching to DisplayPort as an input, after which I immediately receive the message of no signal being found. The external monitor does not show up in the "display" section, and when connected and turned on simply goes to sleep. Since the "update" to High Sierra (which I cannot revert, since it shipped with this OS X), my MacBook Pro 15" (2017) does not recognize my external monitor anymore using the exact same method I used before ( USB-C to DisplayPort adapter). This one shipped with High Sierra, and is now running version 10.13.

Eventually, my 2016 model got replaced by a brand-new 2017 model.

The MacBook Pro was running Sierra as operating system, and it recognized the external monitor.Īfter I went through a bit of technical problems, however. It was a USB-C to DisplayPort adapter, after which I used a DisplayPort cable to connect it to my external UHD monitor (Philips Brilliance 288P). I purchased an adapter so I could connect it to my external monitor (which functions perfectly). A bit ago I purchased myself a MacBook Pro 15" (2016).
