Macbook Pro and sound from miniDVI-HDMI
At what time did MBP start sending sound through the DVIminiport.
In other words: when I get no sound connecting to my TV with a HDMIadapter: Is it the port or the adapter that is at fault??
Ok. Below is a reference to an apple article that lists MBP's that started carrying audio on their mini-displayport.
About Mini DisplayPort to HDMI adapters
It says mid 2010 and later for MBP's.
So where does that place "April"? Well I am inclinded to believe that is not "mid 2010" so your MBP probably does not pass audio on its mini displayport. That means you have to use the analog 3.5mm head phone audio out or you can use an adapter that combines the mini-displayport video with digital audio from USB.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.
What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

Conflict between home sharing from MacBook Pro and airplay from ipad / iPhone?
Just bought an Apple TV, and set it up yesterday. Everything works fine, with one exception. When I have iTunes open and home sharing turned on the Apple TV, when trying to mirror airplay from my ipad 4th gen or my iPhone 5s, I get nothing on the Apple TV, just black screen. It also makes the device run really sluggish.
I've definitely narrowed it down to this conflict, quitting iTunes on the MacBook Pro immediately resolves the issue. So no big deal, right? Just turn off itunes. Except the whole point of buying the Apple TV is to have a central point I can stream all my media in the house from, I'd like to have my MacBook Pro, iMac, ipad and iPhone able to take control of the Apple TV without having to run across the house to turn iTunes on or off on the computers.
This only happens when mirroring, normal airplay audio or video works just fine. MacBook Pro and Apple TV are hard wired Ethernet, ipad on wifi.
Is this a known conflict? Is there any solution?Normally there ought to be an airplay button in the top menu bar (where also the battery, wifi, clock, etc are located). And in display settings at the bottom there ought to be a drop down menu labelled Airplay Display.
If not, it seems that your Apple TV cannot be found. Are both on the same network? Have you enabled AirPlay in the Apple TV (Settings -> AirPlay set to On)? -
Macbook Pro recording sound from external radio
Hi all,
Wondering if anyone can give me some advice on how I can record an external digital radio with my Macbook Pro. As a backgrounder, I am able to do it on my old white Macbook because it has a line-in port, so I just connect a 3.5mm cable from the radio to the Macbook and then I have software (Audio Hijack Pro) to hijack and record it.
However, as we all know, the new Macbook Pros have done away with the line-in port. And the Sound options in System Preferences don't seem to have a function allowing me to fiddle with the headphone port (apparently, earlier models had a function in System Preference that allowed you to turn the headphone port into line-in) but this new model doesn't have that option anywhere.
So I'm wondering if anyone can tell me whether the USB ports or even Thunderbolt can RECEIVE sound from an external device such as a digital radio. I have seen cables that are 3.5mm to USB so I think getting the cable to connect the radio to the Mac is possible, but will it actually receive the sound or just do nothing? Or is there some other way I can record an external device I'm not thinking of, bearing in mind I don't want to use the Mac's microphone to do it, as I will of course get all other ambient sound in the room at the time, and I don't want to rely on an internet stream of said radio.
Thanks,

What if it was a digital radio, would that make things easier by way of using just a 3.5mm to USB cable? Especially because a quick search of a USB Audio Interface brought up some expensive results.
Also, as a possible alternative, after some extensive research online, I've found an iMic USB Audio Device by Griffin that is essentially an adaptor with a USB cable on one end and a Line In port on the other, thus allowing me to connect a 3.5mm to 3.5mm cable from the digital radio to the adapter, and then the adapter goes into the MBP USB port. It's on Amazon and it claims to function as a way to plug microphones and other external audio equipment to it. It seems pretty straightforward, which sometimes has me thinking it's too good to be true.
The output from your radio is analog, regardless of whether the radio is 'digital' or not.
You need a USB audio interface. The iMic is a USB audio interface. -
Macbook Pro no sound from internal speakers or headphones
I have a macbook pro (mavericks). There is no audio coming from the internal speakers and when headphones are plugged in there is still no sound. There is no red light coming from the headphone port either. Any advice?
Try plugging the headphones in and out 10-12times, while toggling the volume and mute buttons.
Have you tried cutting the end off a cotton swab and GENTLTLY swabbing the the headphone swabbing the port 9;00 clock to 3:00 clock, there is a micorswitch that some times gets "hung up" and this can free up the witch.
Also you can try going to to applications/utilities/ Audio MIDI Set up. app and see if you can select built in there.
To get more aggressive you can try these options:
Close all windows and quit all applications.
Click "Go" menu in the Finder menubar.
Select Computer, then Macintosh HD > Library > Preferences
Open "Audio" folder.
Right click these two files and select "Move to Trash".
com.apple.audio.DevicesSettings.plist
com.apple.audio.SystemSettings.plist
Close the window. Restart the computer
Go to Applications/Utilities/Audio MIDI Setup/Built-In Output/Output and in Format change from the default 2ch-24bit integer to any other format (say, 2ch-32bit float). This should activate the headphone jack. I moved the format back to the original 2ch-24 integer setting and the headphones continued working. So it seems that (for some reason) the original default setting does not recognize a headphone being inserted, but after performing this "resetting" it seems to come to its senses and behave properly from then on
if these do help your issues, please post back, there may be other options.
It is best to start a new post, rather adding on to an already existsting, as you will get more people looking at it, and thus offering more advice/sugestions. -
Macbook Pro - No Sound from internal speakers + No red light
Okay so I know this a very famous issue (I've seen over a hundred threads with people having the same problem) but the problem I'm having is something I haven't seen anywhere else. I recently tried to fix my headphone jack on my Macbook pro early 2008 model when it DID have a red light emanating from it but when I finally managed to turn it off with a little wiggle from my paperclip the sound still didn't turn back on. In my system prefs my sound output still displays "Digital Out" and no other option for internal speakers. I know my speakers are fine because I can hear the startup chime. Also, I had a broken piece from my headphones stuck inside the jack a few years back and I retrieved it in....let's just say, not the most professional way to do it (I completely destroyed my headphone jack while attempting to retrieve the broken piece and now the hole is too wide for any headphones), though afterwards the internal speakers still worked for a while, it was just the headphone jack that was messed up.
Basically what I'm trying to say is: is there a way to enable my internal speakers without using any hardware methods? Because I tried the paperclip fix and the red light did turn off, but still no audio + sound prefs still shows 'digital out'. I really don't care much for the headphones jack anymore because I'll just override it with some USB headphones.
Thanks in advance

'Only displays Digital Out'
'My jacked up headphone jack (no pun intended, although very relevant)'I agree Nick - it is a concern especially on such a basic function (sound) - Linc is right, the issue is microswitch, sounds like a bad design or a huge batch of sub quality switches, checking the forums this issue is common on MBP's.
Judging by the date and lack of further activity I assume you managed to get yours fixed at the genius bar ?
I finally fixed mine myself but posting reply for others who have same issue as this - however buyer beware folks, try this at your own risk !!!
The fix won't be liked by Apple Support, the genius bar, or the repair shops but it worked for me after over 12 months of using headphones / external speakers - WHAT A PIA !
Method -
Held Macbookpro on it's side with screen open and headphone/ audio port facing toward ground.
Took WD40 can with straw dispenser and placed straw inside audio port - sprayed 3 or 4 one second burst of WD40 into port.
Held MBP that way for 30 seconds giving MBP a shake to drain WD40 out
(I performed this whole excercise outside where the WD40 could drain out without an issue ;-)
I then took an old set of headphones and re-inserted / removed them from the audio port approx 20 times in and out with music playing on the MBP - intially when inserted music will only come from headphones then eventually MBP internal speakers start working !
I've tried everything else including the cocktail stick and bent pin inserted inside the port to try and free micro switch - nothing worked it was stuck fast.
As stated, can't endorse this for anybody else - you do so at your own risk - just stating this is what I did to get mine working again ! -
HT2494 2012 MacBook Pro - no sound from internal speakers, red light in headphone port
Mid 2012 MacBook Pro 15".
I normally use external speakers plugged into headphone jack.
The other day I unplugged the external speakers and when I re-booted my Mac, I got the start up sound
but I have no sound coming from my internal speakers. In System preferences sound output I see no entry for internal speakers.
I also notice a red light shining in the headphone jack port. I see on youtube that this problem is rather widespread.
Some suggest using a paper clip to try to turn the light out, but I am not doing that.
I have Lion installed, tried using the MIDI-app to reconfigure the speakers, but I only get sound if the headphones are plugged in.
Is this a software or hardware problem?
I have a genius bar appointment today at my local Apple retail store, and my mac is still on warranty but this
is troubling that you spend $2300 for a laptop and after a bit of regular use the internal speakers no longer work.
Any ideas?

Hiya,
I moved a 40GB file off my MacBook Pro to make room so that I could enable the iCloud Photo Library. I optimised the storage but during this process it used 10GB of space and so I cant now put back the file I took off my mac. I though that once I had optimised the storage I would gain space not loose it!. So i'm wondering how can I delete photos off my MacBook and not off all my devices and so I can get this 40 GB file back on ??
CheersHi, that's how it works. photos in Photo Stream are these ones that actually exist on your Camera Roll. Photo Stream is an iClous service that helps you to share photos. Just think about Dropbox or any other cloud services, isn't it that you delete a file on your computer, then found the file no longer exist on your other devices?
If you want to keep the photos while making them occupy less space, I suggest you try SafeEraser's Photo Compressor feature. It compress the photos and make it easy for you to keep them on your iPhone without losing much quality. -
I had a repair done on my MacBook Pro and had to have a new hard drive installed. The Apple Auth Repair Shop then updated the OS from 10.6.8 to 10.7.5. Now my iPhoto v 9.2.3 will not open and it sounds like it will not work with this OS. Can you please advise?
You may need many other updates to retain compatibility with Lion. I suggest you reinstall Snow Leopard. Unfortunately, you will need to erase the drive first. Be sure to backup your data if you haven't done so already.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
After the chime press and hold down the "C" key. Release the key when you see
a small spinning gear appear below the dark gray Apple logo.
2. After the installer loads select your language and click on the Continue
button. When the menu bar appears select Disk Utility from the Utilities menu.
After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, click on Options button
and select GUID, click on OK, then set the format type to MacOS Extended
(Journaled, if supported), then click on the Apply button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. After you finish Setup Assistant will complete the installation after which
you will be running a fresh install of OS X. You can now begin the update process
by opening Software Update and installing all recommended updates to bring your
installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1. -
I have a mid 2009 Macbook Pro and i know the Mini-display port does not support audio out but does it support HDMI out? or do i have to buy a Mini-display to DVI and then a DVI to HDMI adapters?
Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in. That's about all you can do.

Cannot play audio from macbook pro 2009 to tv using hdmi with adapter
MacBook Pro 2009. I cannot get audio from my my macbook pro to tv using an hdmi adapter
That is because the 2009 MBP does not support audio via the minidisplay port. You will have to tap the audio output port for audio and use the RCA audio input connections on the TV.

I have recently changed from a macbook to macbook pro and all my files were saved on time machine but some won't open. How do I open them?
Are you trying to open the backup files via the Finder or an application? If so, that's not how you should access your backups -- use the "Star Wars" display, per #15 in Time Machine - Frequently Asked Questions.
How did you get your stuff on the new Mac?
It sounds like you may have skipped the offer to transfer it when your Mac first started up, created a user account, then used the Migration Assistant app instead. If so, that may be the problem; doing it that way means you end up with an extra user account, and can lose permission to files on other volumes, especially backups.
Please clarify just what you're seeing, and whether you still have the old Mac. -
