Headless Mac mini 'quirk'
« on: May 31, 2015, 10:50:10 PM »
I've mentioned how bad the cheap monitor on my Mac mini is/was. Early last week, in a fit of 'Spring cleaning itis", I decided to simply remove the monitor and put myself out of the misery! It was also taking up so much vertical space, it was blocking the 12 slot 'storage' case where I stash papers that are too important to trash... for at least a couple of years, anyway.

I'd already been using Screen Sharing for months, so that would/should suffice for the rare moments when I needed to actually enter some data or click a button. That meant I could also remove the keyboard and make more room for another stack of papers that I eventually stick into the 12 slot, mostly IN box! ;)

Things were fine until yesterday when I finally noticed that the Menu Bar was almost completely black! :o I knew I had been using "Dark" mode, but changing that didn't help. None of the other Accessibility settings did much of anything (clue #1). Decided I may have been asking too much from the Display Color settings, but I was getting no visible response from any of the controls (clue #2).

I finally decided an interweb search was my only the only solution. Of course, search results are highly dependent on how the search is worded! I found thousands of hits explaining how to enable/use/set Yosemite's "Dark" mode. Thanks, but that's not the problem, folks... But my perseverance (many call in my hard-headed, mule-like stubbornness :P) paid off when I found a thread entitled exactly what I had searched for! How can I get rid of a black menu bar? There were actually two ways to 'fix' the problem. One is a command to paste into Terminal (or into the Terminal access box in PathFinder). The other is a hardware, and supposedly permanent one, it even comes in two varieties!

The problem is that without a monitor connected to the mini (and some even report the same problem with the Mac Pro!), the GPU gets 'confused' as to what to show and how. Images, windows, text, icons, most other stuff, no problem. "Menu Bar"? That sounds like some kind of candy! What does that have to do with computers, besides, Windows has the Menu bar in every window, right? [banghead] The fix is to 'trick' the GPU into thinking there is a 'virtual' monitor connected. ;D

The Terminal 'fix' is subject to being erased by a loss of power shutdown or other un-controlable memory happenings. The kind of "memory happenings" from which I seem to be experiencing more and more. :rolleyes:

The hardware solution has proven so successful that there is now an OS agnostic, relatively cheap, manufactured, extremely niche product available at Amazon!! For those with more time than aesthetics, there is the:

D-I-Y method

...or the "fit" method at

Amazon!
Hope this helps people from losing their patience when losing the head on their mini! :)

Interesting post. Thanks for sharing.

P.S. It took me a few minutes to check out the links. Next time, if you leave the quote marks out of the hyperlink, others will not have to remove those in order to see the linked item.

One per month is quite tolerable. Keep up  the good work.

Something (it couldn't possibly be me!) was inserting the extra http:// and the quotation marks, even after I deleted them (most of them, anyway)! [banghead]

OK, I have now used my normally secret powers to fix the interweb tubes (sorry for the technical jargon). The links work now, at least from my computer. If they don't work from yours, please contact DARPA and tell them I sent you, otherwise, they may not talk to you...

Another mouse-trap: A-B switch (Re: Headless Mac mini 'quirk')

Dear X-Air, Blick, Herb, and WeatherCat computer hardware tinkerers,

I've mentioned how bad the cheap monitor on my Mac mini is/was. Early last week, in a fit of 'Spring cleaning itis", I decided to simply remove the monitor and put myself out of the misery!

If you can keep multiple computers reasonably close together, another trick is an A-B switch that allows you to switch USB and monitor connections from one computer to the other.  I started using this setup when I was still running a LINUX server so remote viewing wasn't practical.  It has a few modest advantages.  You can watch the reboot sequence for example.

FYI . . . .

Cheers, Edouard

That sounds like fun! [cheer] I'll see if I can work that in between watching the grass and the trees grow... and, even that will have to wait while my recent painting job completes its curing! [woohoo] [biggrin] But thanks for reminding me that I forgot to order the dongle! [banghead]

I can only assume those are just some of the Amazon employees! Or maybe they have just seen your weather site displayed on a big screen!
