No audio when with second monitor attached and using Extend, Duplicate,or Second Screen Only modes

When I attached a second monitor via HDMI cable and try to use Duplicate, Extend, or Second Screen only display modes, I can get the video to display and run but I get no audio unless I set the notebook display settings to P/C Only mode. I really want to use the second screen for PowerPoint/Presenter View and play a embedded video (along with the sound). Even if I try to play a YouTube video I can only get audio when in P/C Screen Only mode. Any assistance would be greatly appreciated. Thank you.

Hi,
Please disable HDMI sound to force audio back to the laptop or use different conection such as VGA or DVI. To diable HDMI sound, please right click speaker icon > playback devices > right click and disable HDMI sound.
Regards.

I have an 27 inch apple iMac 2010. Can I upgrade by buying a Mac book pro and use plug in and use the iMac as a screen only?

Yes your 2010 supports Target Display Mode using MiniDisplay Port input.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Crazy crazy crazy! Airport loses internet when second monitor attached!

Can this really be happening? I decided to try using a second monitor attaching via a mini dvi -dvi converter. Several attempts to get it recognised by the iMac without any success. Scoured the internet groups to see that very many (and I mean very many) others had this problem.
Solved it by swapping my dvi-I lead for a dvi-D lead. The difference is that the DVI-I lead has fewer pins than the DVI-D lead and the iMac mini dvi socked supplies a DVI-D signal. Phew!
So--pleased with myself at surmounting this I fired up Final Cut Pro, dragged the canvas window to the second monitor and had to play around with the resolution setting to get a stable playing of the timeline.
Decided to go on online and see if I was alone on this.
NO INTERNET CONNECTION!!!
30 mins later decided to unplug the second monitor (Philips 200) and got back my inet connection.
Tried the routine again and sure enough each time the second monitor was connected I lost the Airport connection!
Is it possible that the proximity of the second monitor fouls the wireless signal?
Or what?

As I said this loss of internet connection when 2nd monitor is connected is unbelievably odd.
It sounds like another case of EMI (Electromagnetic interference). I believe this is at the root of all these weird Airport or wireless problems. Interestingly enough many of these anomalies are exhibited on the newer generation Macs. Different materials were used, shielding could have been compromised either for cost cutting or by design error. Regardless I'm sure Apple is aware, unfortunately those who purchased these machines may be in the worse case, left with hard wiring for reliable internet and or network connections.......sorry.....

Mac mini will not boot up with two monitors attached

New Mac mini running OS 10.10.1. I have a LCD monitor attached to the HDMI port, and a Cintiq 21 UX LCD monitor attached to a thunderbolt port.
It boots up properly with only the first LCD monitor attached to the HDMI port.
When I leave both monitors connected before starting the computer I get no chime, and a black screen. The light on the front of the Mac mini comes on, but nothing else happens. I have to turn off the Mac mini, unplug the second monitor and then reboot. It always starts up perfectly then. After starting the computer, I plug the second monitor in, and everything is fine.
It’s kind of a pain in the neck to constantly plug and unplug the second monitor from the back of the Mac mini. Is there anything I’m overlooking?

Thank you, Illaass! Resetting the SMC solved the problem! I tried that first because I would prefer not to lose any preferences, and also because it was the easiest to try. You must be a genius in addition to being such a good egg!
(This is the number of smiles I smiled after my Mac mini booted properly with both monitors connected.)

When booting up I cannot get past the light blue logo with spinning disc. I have tried it with the install disc and using different keystrokes, i.e. "shift, s, c, o, " please advise. thank you in advance.

The system on the original install dic is probably looking for the original video card.
It may be possible for someone with the right skills to make an install disc for you with the driver for your new card.
As I recall from my early days of being a Macuser, If you held down a key, (spacebar?), while starting it would open a dialog to take you through a monitor setup.

I just downloaded the trial of Photoshop. Every time I try to open it, it comes up with an error message and closes less than 5 seconds into being opened.

i7 is quite fast. that's what i am on too. You may need to
It would be necessary that you have to use "Adobe Creative Suite Cleaner Tool". (see Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6 )
The order varies depending on your individual needs:
1. Maybe you have to activate/deactivate, so please have a look there:
http://helpx.adobe.com/x-productkb/policy-pricing/activation-deactivation-products.html
2. Sometimes, we know in the meantime, the "opm.db file" is the culprit. In this case you should delete it.
3. Did you already try "uninstalling and re-installing"? Be careful with (de)installing aso. by (de)installing by your own resources. As much as I regret it and as strange as it may seem I fear it's a challenge for Adobe's Creative Cloud Cleaner Tool. Sometimes - for whatever reasons - CC doesn't "want" to work. In this case you should CC completely delete and reinstall by help of Adobe Creative Cloud Cleaner Tool. (A try to uninstall by own resources is not enough!)
I quote: Adobe Creative Suite Cleaner Tool helps resolve installation problems for Adobe Creative Cloud and Adobe Creative Suite (CS3-CS6) applications. The tool removes installation records for prerelease installations of Creative Cloud or Creative Suite applications. It does not affect existing installations of previous versions of Creative Cloud or Creative Suite applications.
Please use: http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html and follow the prescribed sequence of operations

If you go to Disk Utility, can you see the drive on the left hand side? If not, then the drive is dead. You'll have to buy a new drive.

Ok, one of my problems is that when I arrive it will take me a few weeks to get a social security number and only t-mobile will give me a sim without a ssn - but edge for a few weeks will be better than no iPhone.
Unless someone out there can suggest an alternative?

Hi all. I want to make audio chat with my brother. I use iChat on my MBP. He uses Gtalk on his windows PC. The problem is that the audio icon is gray. Is there anyway? Can iChat make voice chat with Gtalk on windows?

Hi all. I want to make audio chat with my brother. I use iChat on my MBP. He uses Gtalk on his windows PC. The problem is that the audio icon is gray so I cannot start audio chat. Is there anyway? Can iChat make voice chat with Gtalk on windows or not? I am confused.

HI,
You need to satisfy several things along the way
Account type
You need to have a Jabber or Google mail Account your self.
If you have a Google Mail Account then it needs the "Talk" option Enabled in your Google account Settings ( A Facebook with "Chat" enabled is also a valid Jabber ID to use in iChat).
Connection Method
This is about which apps can connect to which apps for Video ro Audio to work.
iChat Video when using a Jabber account is iChat to iChat Only.
iChat connects using a process called SIP (Session Initiation Protocol)
Jabber based Apps if they have an A/V module connect using protocol called Jingle.
Needless to say Google do their own version of this that is written in to the web Browser Plugin that allows Video Chats (there are PC and Mac versions), and in the PC app called GoogleTalk.
However it is also not that compatible with other Jabber apps.
See Jingle here
This claims, now, that Google had a hand in writing the Protocol.
Also in the "Clients Supporting Jingle" list many more version of Google products are mentioned with extended info. (it suggests that someone at Google has been editing the page).
Can iChat make voice chat with Gtalk on windows or not?
The specific answer to this to be clear is NO.
We are talking about different Apps (or web Browser Plugins) using different Internet Protocols that are not compatible.
The simplest thing is to get the Web Browser Plugin (However there can be issues with the Flash Plugin)
At one time Google used Flash to do Video Chats and it would seem their Plugin is very close to this part of Flash.
See the Known Issues and the "Google Talk Plugin Disables iSight On Mac" item.
Options
Use a Web Browser yourself with the Plugin.
Use a Flash Base Site such as MeBeam (Flash has to be enabled in your Browser and the instructions are simple on the page)
Try to find a Jingle capable Mac Jabber Client (app) ( I have not found one).

I am so glad to hear about your success. As you are new to the Mac environment, I will be glad to help you more.
You said: "I can't change the setup yet but i have access". I don't understand what you mean about changing the setup! Please let me know more about that.
I also recommend to use Boot Camp, which allows you to install windows on a partition of your internal hard drive. This has many benefits. First, you can restart your computer and start up in windows. This makes your Mac device a complete windows machine and you gain the most from your hardware when working in Windows. Second, if a problem occures to your Mac OS X, you can restart your machine in Windows and prevent your data from getting lost. Third, you can import the Windows installed on the boot camp partition in to the Mac OS X using VMWare Fusion and work with it as a virtual machine. In this situation, VMWare enables you to work directly with your Windows in the boot camp partition. So it does not create a file package for the virtual machine in OS X.
Regarding the data safety and reliablity, I strongly recommend using Time Machine. You can also set it up to back up your virtual machines or not. This is possible to set up in the Virtual Machine Preferences Page in VMWare Fusion, or in the Time Machine preferences page in the System Preferences app of OS X.
Please don't hesitate to ask any other question. I will be glad to help you.
