Sound Issues with macbook pro 13" and external display

Hey guys I have a 13" macbook pro from mid 2012 with 8 gb ram and the i7 processor. About a year ago I bought a thunderbolt to hdmi adapter and hdmi cable to use my 32 in tv as a monitor. It worked flawlessly and I never experienced the flickering issue people have been talking about. The tv is only 720p so the picture wasn't as clear as it should be. I was also tired of using a pullout desk and thought the 32 in was a little too big so a couple weeks ago I added an entire desk setup in the corner and bought a brand new 24 in Vizio E241i--a1 and mounted it on the wall as a monitor. This tv is the full 1080p. Ever since then, I have had trouble with the sound playing from the macbook>displayport-hdmi adapter>hdmi cable>monitor. I select the monitor as the output device and sometimes it will actually play and sometimes it will not. I mostly use the macbook in clamshell mode when at my desk but sometimes I have both screens on. No matter what if the sound has stopped working it will not go back. If I select the macbook speakers as the output then it will play through the macbook speakers. But once I switch back to the hdmi output for sound it still will not work. The only thing I can do to fix it is to leave the macbook in clamshell mode and then restart it causing the monitor to be the main display at boot up. Once I got the new tv, I also started experiencing the flickering issue people have been talking about with the external monitor. I know it is not because of Mountain Lion because I had Mountain Lion when I used my old setup and never experienced either of these problems. Any ideas on what could be going on? Thanks in advance

Did you format the external drive for use with OS X?
Open Disk Utility. Does Disk utility see the connected drive?
Format it to "Mac OS Extended (Journaled).

Sound issues with MacBook Pro

I am experiencing sound issues with my MacBook Pro. I am using a headset and when I am on a skype calsl I have a hard time hearing the other person, the sound is coming in and out and sounds digitized. This issue only started recently, the sound had been working fine for years before this issue.

I do not use Skype, but may be information from the below linked article helpful.

Mid 2010 Macbook Pro sleep and external display problem

I recently upgraded to the new 2010 15 inch core i7 Macbook Pro. The problem i have is that it will not detect an external display (23inch Cinema) after waking from sleep. This happens after using the display to extend the desktop and also when using the Macbook in closed mode.
I've managed to get it to detect the display only after either restarting the Macbook completely or by going into energy saver and switching to dedicated graphics then going back to detect display.
It seems that when on integrated graphics it doesn't register that an external display is connected. If i leave a program open and running that causes the dedicated graphics to kick in then it works ok. If i close all programs, shut the macbook pros lid, computer sleeps and external display shuts off. If i click the mouse to wake with lid closed, apple logo lights, machine starts up few seconds later macbook returns to sleep. If i open the screen the machine wakes as normal but the external monitor doesn't.
Any help is much appreciated as its starting to frustrate me now...
Many thanks
oh and im running OSX 10.6.3

I thought it was intermittent to begin with until i started looking into it. By leaving programs open, like aperture, before i put the machine to sleep it appears to wake the external monitor up without a problem. If i shut all programs or leave basic things open like safari and mail which don't require the dedicated graphics, then upon wake it wont register an external screen is connected.
Manually detecting displays in settings doesn't work.
Disconnecting and reconnecting mini display port doesn't work.
Turning off power to cinema display and powering back up doesn't work.
To get the display going again its either 1) turn off macbook pro and re-boot or 2) re-start the machine then the display is automatically recognised. Or 3) launch a programme that kicks in dedicated graphics then manually go in and detect displays again..... like magic the display then springs to life.
No ideas anyone??

Asus VH242 Sound issues with Macbook Pro

Does anyone know how to configure the MacBook Pro to make the sound come out of an ASUS display's speakers?
I have a ASUS VH242 display with internal speakers. With a laptop the Display's internal speakers work but not with my Macbook Pro. the sound comes out of the closed Mac.
FYI - I am using the little connecter that Apple sell to connect the display & i'm on OS 10.7.2
Thanks

Thanks for the reply:
My Dell PC (for work) uses the speakers in the Asus Display and my Mac won't. I'd like to have the sound come from the Display with the Mac also as the sound is not as good due to closing the lid.
Macbook Pro 15" bought on 17-Aug-2010 in an Apple store in NY (I'm don't know how to find the year on the Mac)
The connector was bought from Apple but can't find it (bought in the last two years). It is almost the Apple Micro DVI to DVI Adapter (although the rectangular female display connection is flush with the housing, like the "Mini DisplayPort to Dual link DVI Adapter" is).

Issue with MacBook Pro trackpad and Adobe Lightroom 5

I'm using Lightroom 5 on a MacBook Pro (mid 2012). Whenever I'm in the development tab I am unable to click on anything within the center third of the screen. If I want to get to the 5th or 6th photo in the bottom pan, I have to use my mouse. I am able to click on things only on the left and right sides of the screen for some reason.
This only happens in Lightroom. Any ideas?

Thanks for the quick reply.
Lightroom 5.7.1
OS X Yosemite (10.10.2)
I'm not using an external display. If it matters my MacBook is a 13".
As an example of what I mean, look at the image below. Everything highlighted in green I'm able to click. After I'm in develop for more than a few minutes, I'm suddenly not able to right click or left click on anything. The typical "mouseover" changes don't happen either, such as the subtly highlighting that happens when you mouse over an image in the bottom pain. As if Lightroom isn't detecting the mouse there at all.

Weird problem with Macbook Pro 15" and Asus PB278 monitor

Hi there
I recently bought a brand new MacBook pro 15" the one with a dedicated nvidia 750 vid card. However I'm facing weird problems while connecting it to a external monitor Asus PB278 (1440p monitor). I use a mini display port to display port cable.
My problem is: Sometimes it works perfectly, but then if I put the laptop to sleep, sometimes it won't recognise the screen at wake up, at first I tried to restart the system, power on and off the monitor, connecting and reconnecting the cable... nothing worked. I even bought a expensier cable thinking it was probably a low quality cable. I found that then only way to fix this is to connect the monitor with a mini display to HDMI cable I have (won't support over 1080p), and then put the mini display to display port cable again... it is freaking bizarre.
This is very frustrating, I live outside the US and while the retailer will honor the guarantee I'm not sure if this is a Software or Hardware problem, It will take them about 3 weeks to replace my system which is unfortunate due to I have plenty of work to do. I don't want to send it on guarantee just to find out hey... display recognition is broken again. My questions are:
Is there a way to know if this is a hardware or software problem?
I've heard Yosemite is having some issues regarding external displays, is this one of those?
Have you found yourself experiencing this problem? Could you fix it?
Sorry if my english is a bit weird, thanks in advance.

Hi Gatobolo,
Thank you for contributing to the Apple Support Communities.
It appears that you've discovered unusual behavior with your MacBook Pro and an external display, where you need to temporarily connect a different display adapter before you can use your Asus PB278 again.
I can offer some additional tips to help resolve or further isolate the issue you're seeing.
First, try the following resets to see if they eliminate the behavior:
You can reset the Mac's parameter RAM and SMC.
Next, if the issue occurs again, try restarting your Mac into Safe Mode:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
You can find the steps above in this article:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
If your display is recognized in Safe Mode, or after restarting again, the issue may be due to a software conflict.
Another suggestion mentioned in the article above is to try a different type of display adapter, such as a Mini DisplayPort to Dual Link DVI adapter.
If the issue persists, you can also back up your data, erase your hard drive, and reinstall a fresh copy of OS X Yosemite.
OS X Yosemite: Erase and reinstall OS X
If the issue still occurs after a clean install, troubleshooting the hardware may be necessary.

My macbook pro freezes and then displays a blue screen with black stripes... do you know what's wrong with it?

My macbook pro freezes and then displays a blue screen with black stripes... do you know what's wrong with it?
I have a two and half year mac book pro... I've had some issues with the screen looking scrambled when I quit certain applications, but now it's turned into something worse. I'll be working on my computer and the thing will freeze. When I force restart, the first screen, the apple logo, will be a blue tint and won't boot up normally. Then I try safe mood and it will then boot just fine. But there are blue stripes on my screen. The screen alternates from a blue tint to normal and if the computer freezes again the screen will become completely blue with black stripes. I haven't tried reinstalling my software because I don't have the startup discs that came with my computer. If I was sure that would fix it I would purchase them, but if it's a hardware issue I'm afraid that I'm screwed. I've been able to successfully get the blue off my screen by putting it to sleep and then waking it up, but that's not working well anymore either.
Does anyone else have experience with this? Is it the firmware or what? I have a MacBook Pro from early 2011 and I'm running Mac OS X 10.6.8.
Please help... Thanks!

I just experienced this exact same issue with my early 2011 15" macbook pro. Since like a month after purchasing it I had issues with the screen randomly going dark on me. I sent it in for repair inder waranty they replaced the gpu and logic board but I continued to have the same issues with the screen randomly going black sometimes I would need to reboot it in order to get the screen to go back on but it happened so infrequently and I used the computer for school so disnt find the time to resend it in to apple. Just last night the screen started to display the blue screen with black verticle lines on it. I called apple and explained to them the issues that had been ongoing since I purchased the laptop but they said because I was now outside of warantee that any repairs at thia point wouldn't be covered. Fml so glad I spent 2200 on this future proof macbook pro what a joke my sister purchased a toshiba laptop for 300 4 years ago and it still running like a champ. I loved my macbook but at the price I paid I expect it to last longer than 2 years before leaving me high and dry. *** apple??

Blue tooth issues with macbook pro late 2011

I purchased the new beats pill and havinng issues with connectivity with macbook pro. My Iphone works well. Any suggestions

I have a similar issue. Have you had any luck with a fix, yet? I have a Samsung sound bar, and my Ipad and Iphone both connect with no issues. The playback is uninterrupted with fine sound quality. My 2011 13" Macbook Pro connects, however playback often sounds like a scratched CD. Last year I called both, Samsung and Apple, and when all was said and done it was recommended that I bring the then brand new sound bar and my Macbook to an Apple Store. Any suggestions I are appreciated.

Is there a faulty hard drive issue with MacBook Pros recently? (I say recent, mine was bought about a year ago)

The reason I am wondering is because previously my MacBook Pro crashed and failed to load past the white screen with the logo and a spinning disk.
So after googling the problem, fiddling about in recovery mode (which is pointless given I know next to nothing about computers), I went to an Apple Dealer
and they very kindly re-installed OS X Lion for me, because the hard drive had decided to play up.
Now, I am again facing problems with my hard drive, after both Safari and iTunes crashed. After this Safari refused to open and I restarted several times before a loading bar appeared at the white logo w. spinning disk screen, and after the loading bar filled my mac finally managed to open Safari, albeit minus the close tab 'x', only now, it is also claiming there isn't enough memory to open iTunes (there is, almost 7 GB of free RAM) and after installing ClamXav and Sophos and finidng no viruses, I ran Disk Utility which informed me after I had verified the disk that I need to run in recovery mode using another disk (which, I don't have. My family has another mac running Snow Leopard and I have no disk for OS X Lion... or would an external hard drive do?) and that I need to repair the disk using Disk Utility.
Any help/ideas would be greatly appreciated
Additionally, a program that I have called Sibelius also plays up at around about the same time that the disk keeps crashing. Could this be the cause...?

Welcome to the Apple Support Communities
As far as I know, I haven't noticed any problem with the Mid 2012 MacBook Pro about their hard disks. All hard disks fail with their use, but it looks like the hard disks you had on your Mac were defective (at least, the last one). If the hard disk was replaced recently, you should be able to take it and they should repair it for free, or at least, that's what Apple does on Apple Stores

Front Row issues with MacBook Pro?

I just bought my MacBook Pro today and transferred all my files from my old Mac via firewire. I run Front Row, and it says "an error has occurred" every time i try and play any playlist OTHER than the playlists of stuff bought from iTunes... any ideas?
Also --- how do I NOT make it shuffle?
Thanks!

ohhhh
No, actually, I leave my folders somewhere else. That must be why, because my downloads ARE there!
Another question then...if you guys know...I reinstalled Entourage, and I'm now told that I can't access that identity with this version of Entourage!
Thanks, you guys are awesome.

Issue with Macbook Pro 2011

Hi there. I have a brand new MacBook Pro 2011 and I'm having some problems with my wireless connection. I have in the same room a Mac Mini, my Ipad , my Ipod, 3 PC's and all of them have a wireless connection. I notice that since my last MacOSX update I have some problems with my wireless connectivity in my Macmini. Now I'm having the same problem in my macbook pro. I have internet in all my other devices but no internet in my Mac Mini or Macbook. The Access point is 5 meters away from my devices. I put some repeater in the middle to repeat the signal but I'm getting the same beavior. Can someone help me on this? If I go to the network setting and renew my DHCP address I can access the internet but after 15 minutes I'm getting the same problem again.

The signal bar on the menubar is not always an accurate indicator of how strong the signal is. A more accurate measure is if the signal drops entirely and you are definitely in range of the airport base station. Also anywhere within 3 meters you may get signal degradation because of overlapping radio waves cancelling each other out. You also have the option to ask to speak to a customer relations person when you call AppleCare, and ask for an expedited repair, and have your airport card properly seated. Sometimes they can get loose, or the antenna can get loose inside, though normally this isn't a problem unless the machine has to be opened for some reason.

USB-3 card reader that is compatible with MacBook Pro (Retina) and Mountain Lion

Can anybody recommend a USB-3 based CompactFlash memory card reader that works with the MacBook Pro (Retina) and Mountain Lion (or, at least, Lion)?
Thanks in advance...

Thanks for your reply, Clinton. But I already have two readers that are USB-2 compatible. Now I need the one like I described above. I am using only the fastest CF cards available.
I have read some user reports (on Amazon) on two readers relevant to my needs - SanDisk and Lexar - but I'm still not sure whether they are fully compatible with the Retina MacBook and Mountain Lion. As a matter of fact, I doubt it...

Issue with MacBook Pro Display

My buddy has a 13" Macbook Pro unibody and recently whenever he puts it to sleep and then goes to open the screen again the backlight for the keyboard comes on but the display does not show up. In order to fix it he has to close the lid and then open it again and the display then shows up. Any ideas on why this is happening?

You should put this question on the MacBook Pro forum. This is a forum for a specific model of MacBook so there is a good chance that somebody who can answer will never see it.

Macbook Pro Thunderbolt and HDMI displays switch on wake up

Hi there,
Currently using a late 2013 15" Macbook Pro., latest version of Mavericks. I have one display hooked up through Thunderbolt->DVI, with a second set up through HDMI->DVI.
There seems to be an issue where on waking the monitors up from sleep mode (about 10 minutes inactivity time) the displays will turn on, immediately go black (inlcuding the Macbook Pro screen), and then switch such that all windows on one are now on the other.
I can't really repliate this, as it seems to just happen randomly. All I can say in my detective work, is that the HDMI->DVI hooked-up monitor tends to take a little more time to turn on after sleep, whereas the Thunderbolt->DVI monitor comes up immediately.
Any help would be greatly appreciated.
Thanks.

I've noticed that the HDMI connection seems to lag the Thunderbolt on wake as well. I haven't had the switching issue, though. I use my Thunderbolt display as the primary (menu bar in the preferences) - maybe try doing that if you're using your HDMI out as the primary.
You can always try resetting the SMC and PRAM as well.
