• Chromebox: developer mode chromebox

  I recently bought a HP chromebox to use a kiosk application. However, to completely install the kiosk application in the way I need to, I need to switch to developer mode.  In accordance with the instructions that I have to

  To call the developer/restore mode, you insert a paperclip and press the RESET BUTTON (just beside the kensington lock) and press the power button. Release the RESET BUTTON after a second.

  Mode Dev first call you the recovery and to the recovery screen, press Ctrl-D (there is no prompt - must be made). It will ask you to confirm by pressing the reset BUTTON again.

  Dev-mode works as always: it will show the scary start screen and press Ctrl-D or wait 30 seconds for initialization.

  However, when I do this the box does not send any video signal to my HDMI screen so I am completely in the dark as to what is happening, if anything. I tried with a wired USB keyboard and a USB wireless keyboard, same result: nothing seems to happen.

  Who has an idea to switch to developer mode on thisHP chromebox? (Not a chromebook)

  Hi @StephanvR,

  Steps performed by you to switch to Dev Mode seems to be OK.

  As you mentioned that you have connected the display via HDMI and there is no display.

  Therefore, you can try to connect to display Port (DP) and check if there are any screen.

  I hope that answers your question.

• Presenter PowerPoint on Mac mini mode displayed on the screen and the projector when using HDMI splitter

  We have a Mac mini connected to a screen and a projector via HDMI using a HDMI splitter.

  It works fine for most applications, but during presentations PowerPoint, presenter is displayed on the monitor and the projector.

  When I disconnected the mini Mac's HDMI cable and put it in a MacBook, the presenter appeared on the MacBook screen (as it should) and only the slide appears on the screen and on the projection screen.

  Of course if we have to use the MacBook for presentations instead of the Mac mini, you would need to have seen the presenter on both the screen and on the screen of the MacBook.

  In the Mac mini display preferences there is no button to "Gather Windows" when the Mac mini is attached to the screen and the projector via HDMI splitter is a tab "setting."

  But these two things appear on the MacBook when it is connected.

  Any help would be greatly appreciated.

  Thank you!

  I'm confused. When you use a video separator the same screen will appear on the two monitors connected to the separator. This is how works a separator

• External display on HDMI overheating my Mac and drains the battery badly

  Hey guys.

  I am using a MBP retina 2012 15 inches with an external monitor, a generic LCD 1080 p via HDMI without problems. And recently updated for Sierra.

  The question starts immediately when I plug it into the screen. The Macbook seems to overheat and run fans above 4000 rpm, which is very audible and boring. CPU and GPU temperatures go above 70 degrees C (normally they make 50 +). The battery holds for only 1.5 hours, generally works well for 4-5 hours.
  I tried killing all apps, followed a bad process in activity monitor, changing default resolution - nothing helps so far. The CPU is barely used by 10%, the memory pressure is fine.
  It's just that time when I plug the screen - Mac starts bad feeling. Never, the problem occurred on El Capitan. Maybe it's a GPU problem, but certainly caused by the OS.
  All the world had the same problem?

  Try resetting the NVRAM (hold down the command-option-P-R on startup).

  Also, try to restart in Mode without failure, then normally again.

  Finally, try logging into your account, sign in to a user account (or the guest account) and connect the external display. Same problem? If it works fine for a new account then it's something in your own account which is the cause - perhaps an element of connection or some other system changes induced by the operating system previous and who does not play nice with Sierra.

• HDMI Splitter El Capitan - Sierra

  I changed my MacMini (end of 2014) to El Capitan in Sierra now. The MacMini is connected to my BENQ via a HDMI splitter. After changing the operating system, the monitor not connect standby while starting the MacMini. Connect the Mac directly to the monitor does not cause this problem.

  Someone at - it had the same problem a solution for this? Thank you.

• HDMI to Vga 2015 Mac

  I have a macbook pro with the retina display 2015. I have a vga screen and a hdmi adapter. Whenever I connect the Hdmi adapter on my mac and plug on my screen of my Mac screen to him becomes black and it does not work. Can someone please give me a solution thanks.

  There is no sensible way (that I know of) to convert HDMI to VGA and have everything continue to work.

  I suggest get you an adapter Mini DisplayPort to VGA and plug on the Thunderbolt port (Mini DisplayPort is a subset of the Thunderbolt).

• The macmini split audio video hdmi using mini stereo out?

  Hello

  I need to play a dvd for the first time next week - for a public event

  using the mac mini mid-2011, i5 2.3 ghz, superdrive, yosemite

  using hdmi connector as the video signal on a vizio tv and...

  I need the audio output through Jack for headphones (stereo mini) for an audio mixer.

  Y at - it no problem with that or everything simply select the audio output from the audio out of system preferences?

  I guess that it is the same thing as my Macbook Pro, where I did just that - if you plug the cable into the headphone jack, it should work without needing to select the output in the Prefs. If you check with a helmet, you must confirm this. Having a video output running will not affect this.

• 1440 p monitor recognized as 1080 p over HDMI

  I've updated to Sierra yesterday, and now my ASUS PB278 displays 1080 p instead of its native 1440 p over HDMI. This monitor has worked flawlessly with El Capitan and Yosemite on HDMI.

  I also tried to connect more love at first sight with an HDMI adapter and that no longer works.

  Anyone else having this problem?

  Well Yes. Exactly the same problem you described. In light of this + problems with drivers for my Performance MX Logitech mouse (restless as hell scroll), immediately restored to El Capitan.

  Will be held off the coast of the upgrade until this issue is resolved.

• tvOS 10 update breaks DD5.1 on Apple TV output 4 HDMI

  Then, I upgraded tvOS 10 last night. Now, all the movies content on Netflix or iTunes won't play with audio when I output 5.1.

  I have my TV connected to a HDMI/optical splitter so that it can feed my Sonos Playbar. Prior to the update of the audio has been correctly be pulled the HDMI cable and divided optics 5.1 true, as stated in my application of parameters of Sonos. Since the update, I have to stereo to get all the sounds, which is so obviously not true 5.1.

  Someone else had this problem? Any ideas on a solution?

  Thank you.

  Try the Bike ATV power and sound systems. It is working for me with HDMI to TV and optical out to A / V receiver. It has no reason for the software of the ATV to make it different than before.

• HDMI port defective by design?

  Same problem here - I want to (Oh, man I need) to be able to use my HDMI port to make presentations on an external monitor.

  I recently converted to the technosystem to Apple after being forced by the former employer to abandon in favor of Windows Apple more than 20 years ago.  I like how the iOS works (for the most part) and this terminal is for access to tools based on unix, but for something as simple as a faulty HDMI port - by office? -not what I expected to get my new Macbook Pro.  Laptop my wife 4 + years Windows has an HDMI port that works very well. But my new Macbook Pro?  Nada

  This is not only annoying, but also effects me professionally. I need to be able to use some external displays of various flavours to present my services to potential customers.

  Come on Apple, you can do better than that!

  (1) not talking about apple, it is a form of voluntary

  (2) iOS for smart devices, OS X for laptops, desktops, iMacs, Mini

  (3) you need a lightning to HDMI converter

• Port of question - no video - DVI double separator i7-HDMI > DVI

  What I'm missing here?

  I have an i7 2.3 g-Mini late2012.  10.8.5. in a studio where I fed a dual display

  using a separator of video signals by - everything first, Tripp Lite, now an Aluratek - DVI 2-port video splitter (powered

  units).

  Followed by all the good order in start-up, the device worked for maybe a week and a half.

  Walked away and returned after maybe 48 hours either from Friday to Monday.  Computer is running

  "sleep" mode... The attempt, no signal wake video monitor not recognized.  Powerd deactivation/activation, no change.

  Reset PRAM and disconnected/reconnected Mini power after 30 seconds... tried reconnect splitter/monitors...

  sequence... still no resolution of the video signal to not watch.  Indicators on the splitter show the signal of the i7.

  and connectivity to the monitors.  I excluded this device that the fault.

  Am following the process mfgr correct insofar as the separator like so new out-of-box in reconnecting

  power on it - getting nothing.  Strange thing is, I had the same problem with the Tripp Lite - that's why I

  bought this Aluratek separator to replace.  Now, same problem.

  When connected to same monitors, this worked fine right out of the box.

  Now the same problem as the other separator.  Changed two different HDMI > DVI

  cables. All cables. No change.

  Either monitors directly linking ON the HDMI Mini port - display works fine.

  Tried the MiniDisplay port to the separator. didn't work...

  Which may conflict in operating system - something making these monitors sleep, something system-wise

  who is disrupting this process?  Even pulled all other connections (external USB port stuff) and it

  did not solve.

  It is also a coincidence for two separators to fail with this same issue - seems to indicate something with the

  Mac. In the meantime, no double posting until I can understand it.

  Any help greatly appreciated-

  Thank you

  Mike

  I suspect the power adapter... and maybe check for a loop of mass too.

• How to control a Mac mini with HDMI ports fries and lightning? (The rest is ok)

  Recently, a lightning strike fried video output (HDMI and lightning) ports on my Mac Mini end of 2012. As far as I know, the rest of the machine works fine. It's just blind. I can't have everyone working on this, but I don't want to throw a perfectly (well, almost perfectly) computer works.

  If I can get a control over the Mac Mini for a few days, I could set up as a dedicated time Machine or maybe even an iTunes or media Server. How can I achieve this?

  Configure the screen sharing on the Mac.

  To do this, you must have another recent Mac.

  You can start the problem Mac in target disk mode, connect the two Mac by FireWire or Thunderbolt, boot the Mac problem with button down T, boot the first Mac since the Mac HD problem and sharing Setup screen

  Alternatively, you can take the drive out of the Mac problem and start another Mac that and configure sharing screen.

  You can also get a USB video card and put in place by the target disk mode or by removing the similar disk for screen sharing
