I just decommissioned my 2011 iMac and replaced it with a 2018 Mac mini and a new 27&quot; monitor. The iMac is where I used to play audio and controlling from the keyboard (F10 - F12) was never a problem. I am now connecting to the new monitor via HDMI (v1.4). It will play audio, but I can't control it from the keyboard - I get this instead:   When I go to the Sound in System Preferences, this is what I see for output:  This leads me to believe that connecting via display port might possibly give me the ability to control via keyboard? I can't seem to get a USB-C to mDP cable to send a signal, so I'm guessing I need Thunderbolt 3 to mDP. Does anyone know if that will work before go and buy the cable? Any other tips that may work for getting control of the audio on the keyboard when connected via HDMI v1.4?

When I plug my Mac  into a DisplayPort monitor that has loudspeakers, the Mac's volume controls become disabled.    Is Apple assuming that if I have external speakers I am so much better using their own volume control that I have to be forced to do it?   That is annoying because the monitor's volume controls are buried in terrible menus accessed by terrible buttons on the back of the monitor.  Also, if I am inside an app where I can select the audio device and I select the Mac's internal speakers, the volume controls are STILL disabled.  Is there no way to control the volume of an app when an external speaker is connected even if the app is not using the external speaker?????  Some additional info: It's a Macbook Pro 13" 2018 version.  Using a Thunderbolt to Displayport cable, plugging in to a Dell monitor with speakers.    In another location I use the same cable to plug in to Dell monitors with Displayport but without built in speakers in the monitors.   At that location the volume controls remain active and they control the internal speaker in the laptop as they should.

I'm trying to record both what's happening on screen and the audio being played by the applications. To my surprise, QuickTime did not record the sound. I believe it worked before in previous OS X releases, but that is not something that I use often so I have not bothered to try earlier.  What is the current situation on El Capitan ? Have I messed with something that prevents QuickTime from capturing the sound, or has it never worked ?  Here is my view of Quick Time  / New Screen Recording on a Mac Mini:   On my Macbook Pro, I have the option select None or Internal Microphone. Internal microphone actually records the speakers of the Mac Book as heard from its own microphone, which obviously sounds terrible.  This is a MacMini 7,1 (late 2014) and there is nothing in Input Sources.

When I have my external monitor hooked up, I access it by mousing off the left hand side of my Macbook display. Can I switch this so that I can access the external by mousing off to the right of My Macbook display?   The reason I ask, is my monitor is on the right side of my macbook, and it's unintuitive to mouse left to get to a screen on the right.

I upgraded Yosemite, and turns out they changed the "pop" sound that plays when you change the volume. I have another Mac, which is on Mavericks, and I would like to get the old sound back.  I saw , and it is NOT there in Macintosh HD ▸ System ▸ Library ▸ Sounds  Any help would be appreciated.

Windows 8.1 isn't playing back audio on my 13" mid-2012 Macbook Pro.  I only have a speaker with an x on my notifications bar.  When I click on it, I get the usual "detecting problems" garbage.  Unfortunately, every "solution" I've found seems to work for everyone else, but not for me.    Device Manager  Windows shows a High Definition Audio Controller listed under System.  Its properties state that it has a Code 10 - "This device cannot start", along with "The requested operation was unsuccessful."  This is the only notion of an audio device listed in Device Manager.  Most solutions I've found say drivers need to be reinstalled (downloaded from the internet or simpliy re-run from the Bootcamp support drivers) and I've currently tried the following:   Bootcamp setup.exe (No errors are reported, 5.0.5033 "installs" a variety of sound drivers) Cirrus Audio (Both CirrusAudiox64.exe and a manual .inf installation) Realtek (I've tried nearly every link I've found)  Intel Graphics 4000 (apparently it does audio too)   Every executable runs and reports success, however, I don't see any sign of a change apart from the Realtek driver copying files somewhere in Program Files, and the Intel driver blanking the screen a few times.    Cirrus Audio  I've tried manually installing the Cirrus Audio driver by performing the following:   Select High Definition Audio Controller from Device Manager Click on Driver -> Update Driver Select "Browse my computer for driver " Select "Let me pick from a list of device drivers" Click "Have Disk..." and navigate to the .inf file   At this point windows complains that the driver does not support Windows x64, despite having "x64" written all over it.  "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems."  If I skip #'s 4 and 5, and browse directly for the driver files, Windows reports that the Driver software is already up to date.  "Windows has determined the driver software for your device is up to date."  This makes me believe that Windows 8.1 might have an issue with certain drivers, deeming them unusable in some way.  It's possible that windows is denying the .exe installers' drivers, Realtek, and Cirrus behind the scenes, without letting them install anything.  Maybe they report success and silently fail?    Setup  It's worth mentioning that my Bootcamp setup isn't typical.  I've partitioned the hard drive and installed windows manually, alongside Arch Linux.  (I've triple booted this thing, and windows audio is the final hurdle.)  I'm also using the refind efi bootloader to boot the system.  For the windows boot option, I point refind to /EFI/Microsoft/bootmgfw.efi, without any options. I'm thinking that Bootcamp might do more than partition and install, and that I'm supposed to do more to inform windows about the macbook hardware at this stage.  Is this the case?  Did I miss something critical about Bootcamp?    If anyone can help me solve this, I will be eternally grateful.  Thanks.  P.S. I'm a linux user, so windows drivers aren't exactly my forte.  If I'm doing something totally wrong, please let me know.

I have an older macbook pro with a mini display port. Can I use a Thunderbolt display as an external monitor?

, it says how to use the audio jack as in input. On my MacBook Pro 13" (mid 2012), It doesn't seem to have the option in settings. Is it not possible with these computers?

How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of.

Is it possible to use a MacBook Pro as a second monitor for my iMac? Both of them have a Thunderbolt port.  If not, is there any other way?

I looked for 20 minutes for a post similar to mines, and couldn't find one. Which is interesting to me, because I don't understand why people want to use the display to HDMI instead of using thunderbolt USB-c port natively instead. Before I get to this...I shall ask my question.  I plan on buying a MacBook Pro-2018 15 inch for my home-based business. I need to connect 3 monitors to this laptop. I understand the 15 inch MacBook Pro comes with 4 thunderbolts 3 ports. I plan to buy 3 24-27 inch monitors that are 4k display. Also, I understand that the charger for this laptop uses a Thunderbolt 3 port, which leaves me with 3 left. Will connecting 3 monitors that have Thunderbolt 3 ports leave me with performance issues? Will the refresh rate lower?  Finally, why do I see a lot of post with people using old 2.0 display port to HDMI; why they can use Thunderbolt 3 port natively?

Audio was working fine until I tried to use qjackctl and qsynth to play a MIDI keyboard. I followed * to setup the keyboard and it worked. But then I noticed other applications couldn't play audio (VLC, Rhythmbox, etc.). After a reboot it was fine again. And then I set up the keyboard and the problem was back. This went on for a few days and I thought I could live with it as it fixed itself on reboot. But then it didn't. I couldn't play audio, except via qsynth and the MIDI keyboard. Now not even that audio will play.   *Mostly. qjackctl wasn't exactly as described, but I believe I found all the mentioned controls.  I'm not sure what I really did with qjackctl, or how to get back where I was. I tried removing (with apt-get purge) qjackctl and qsynth but that didn't help. Now I've reinstalled qjackctl and have tried changing the which driver is used by qjackctl, all to on avail.  Ideally I'd like the MIDI keyboard to work, but far more important is getting the audio back like it should be.  I've checked all volumes using alsamixer.   I believe JACK makes pulseaudio stop (see  and , but I don't know how to stop jack and get it back to normal.    How can I make the audio work again?

It seems the new Mac Mini uses both HDMI and Thunderbolt, but bandwidth limitations of Thunderbolt may prevent using 3 daisy-chained Thunderbolt high resolution monitors such as the newly released Apple Thunderbolt 27" Display, limiting you to two instead of three.  If this correct: 1. What occurs to the 3rd monitor in a triple daisy-chain? Black screen? Reduced available resolution up to the bandwidth limit of Thunderbolt? 2. Are there HDMI to mini-displayport adapters for connecting the HDMI output of the Mini to the Thunderbolt input of an Apple Thunderbolt 27" Display? Would that even work?

Is it possible to completely disable the built-in keyboard on a MacBook? No input should be possible from that keyboard when I connect an external keyboard. This is sort of possible with the trackpad and the mouse, is there an option (or indeed a hack!) to do the same with the built-in hardware?

I just bought a new late 2013 iMac and a new late 2013 Macbook Pro retina. Also bought an Apple thunderbolt cable.  Pressing CMD+F2 (enabling Apples "Target Display Mode") on my iMac lets me use the iMac as external monitor for the MB Pro, but I'd like it the other way around (which doesn't seem to work).  Does anyone know how I through Thunderbolt (for speed, am aware that apps like  and Screen Recycler can do it through WiFi) so that my MB Pro becomes an extra external monitor for my iMac?  While  addresses this problem for earlier hardware and software, I'm looking for a solution that supports using a thunderbolt cable and works with late 2013 Macs with OS X Mavericks.

I've seen many of the solutions on the topic, all posted in this site. But I haven't seen any of them mentioning Apple's adapter,   I have that, which was used to connect to my old MacBook Pro 2013.   Now, I'm assuming that all I need is to connect the Mini DisplayPort to an adapter, such as  (as mentioned in one of the posts) and the USB cable to a USB-C adaptor.   Is this correct?

I wanted to use a mini display-port cable then use "target display mode" to make the iMac an external display, but I just read that early 2009 iMac's don't have target display mode as a feature.  Anybody knows of a solution?

I just purchased a Dell P2175Q monitor for my 15" MBP w/Touchbar. I'm connecting with a USB-C to DisplayPort cable, but when I go to Apple > System Preference > Displays, there is nothing about the Refresh Rate. Pressing the Option key does not show any additional options.  I've seen countless screenshots where this information should appear. Is there another way to check the refresh rate?  I'm on macOS 10.13.4  Thanks.
