Running your Mac Mini headless by faking a display for it (HDMI 1080p/4K or Thunderbolt VGA); similar for DVI

Posted by jpluimers on 2017/08/28

The MacMini is a bit dumb as it won’t enable the GPU when there is no display attached. Which means headless operation is cumbersome as display rendering is very slow.

There are a few tricks of which the off-the-shelve HDMI solutions work best.

You can buy them at Amazon:

Basically the trick to simulate a monitor with a dummy load works for other display connectors as well (most of them work fine with 75 ohm resistors, usually a bit lower or higher works just as well):

How-To: Automatically change your Mac’s display resolution when running specific apps [Video] – via: 9to5Mac

Yet another reason I love SwitchResX: : How-To: Automatically change your Mac’s display resolution when running specific apps [Video] | 9to5Mac

A few years ago, SwitchResX helped me switch my Mac machine to 1360×768 and 1888×1062 « The Wiert Corner – irregular stream of stuff

sleep wake – Macbook Air – battery drains while sleeping (but not when shut down) – via: Ask Different

Posted by jpluimers on 2017/08/07

I had the same issue as in sleep wake – Macbook Air – battery drains while sleeping (but not when shut down) – Ask Different which suddenly introduced itself in April 2016 after I had been running El Capitan (OS X 10.11) for a while.

The Mac didn’t have PowerNap active as I verified using How Power Nap works on your Mac – Apple Support

At first it looked like an SMC reset worked as explained by Reset the System Management Controller (SMC) on your Mac – Apple Support and mentioned in Mac Air loses 90% of battery overnight when in … | Apple Support Communities.

The Mac is indeed running Chrome, but I don’t like to turn that off before sleeping.

Executing pmset -g would show hibernatemode 3.

So I opted for the hibernate option as mentioned in the first link:

sudo pmset -a hibernatemode 25

This will take a bit longer to restore the memory from hibernate state, but saves a lot of frustration.

Fix Apple TV No Sound Issue – AppleTV2

Posted by jpluimers on 2017/08/04

The first method I try for any Apple TV issue is to reset the device (Hold the Play & Menu button simultaneously on the remote for 6 seconds)

Source: Fix Apple TV No Sound Issue – AppleTV2

This usually works for me too and is easier/faster than fiddling with the solutions mentioned at Apple TV: HDMI audio stops working – Apple Support (which now has moved to Get help with audio, video, or power on Apple TV – Apple Support).

After releasing Play&Menu buttons, wait for the Apple TV to reboot itself and listen if your remote-buttons will give you audio-feedback from the Apple TV. If that works, then audio on multi-media works fine.

This is way cheaper than putting additional hardware in the HDMI chain as described in The fix for AppleTV HDMI audio and video woes and HDMI problem solving | The Poor Audiophile

In my setup the Apple TV 3rd generation is hooked up to a Harman Kardon BDS 580 receiver/blue-ray-player.
