Mac Mini Display Wake Up Delay or Never

I have the same issue. The display for my Mac Mini wakes up on a delay. The Mac Mini is an input in a 4K TV and after I press the keys of the wireless magic keyboard for a while, the display finally comes up. Very frustrating.

Originally the display would not come up at all. I had the TV plugged in the HDMI output of the Mac Mini. Then I plugged the TV in one of the USB c ports (with an HDMI adapter) and that fixed it....

The other issue I observed is that sometimes the pointer of the trackpad disappears from the screen. Apparently it’s a thing... I made it bigger in the Universal Access settings and it improved the issue, making it less frequent.

Still, all of this is pretty frustrating for a machine that costs $1,400... Everything also used to work with the previous version of the Mac Mini.

Finally, the Apple customer support was really nice but unfortunately completely useless. They didn’t have any suggestion to make except their various types of standard resets which didn’t help. Independently from them I discovered that deleting the windowserver.plist files would enable the display on the TV via HDMI but none of the setting could be changed without losing the output again... As mentioned above using the usb c with and HDMI adapter made the issue go away and the windowserver.plists files started to update correctly.

Hi,

I have the exact same problem and can barely believe it. I've also stopped using the new Mac Mini. It is now just an expensive paperweight. The ridiculous support article that asks you to check if the Mini is even turned on is an insult. None of the advice works. How can waking up an external display via HDMI be rocket science. My Raspberry Pi can even do it.

None of this works. I have a blank slate Apple Mini straight from your factory. You seem to not realize that your product - not us - is having a problem.

I got the three year service plan on this Mac mini so maybe after I start wasting your money and time by calling your service support and dragging them on for hours upon hours and wasting your money until you finally decide to fix the problem.

you're not the only one. I've spent more time on the phone with them than anyone the past week that i've had it. Bone stock, no changes/apps. i've used this maybe 8 times in the past week now and i've had to dick with the cmd+op+p+r bs routine several times and even had to unplug the device numerous times before it would finally turn on.

I'm honestly going to return this thing within the next few days if a software update doesn't solve this problem. This is a well known issue and several people have posted about it within the boards, and I haven't seen anyone from apple chime in about it.

it appears that my issue was the Alienware Gaming Monitor. - 34" Curved MDL# aw3418dw. I've rebooted twice now, even powered it off completely and turned it on with ZERO problems. I have two of these monitors side by side, and an Asus 34" curved overlooking the two. Plugged it into that and bam, worked like a charm.

The problem is still with the Mac if that monitor works with other computers.
