Does anyone know why my macbook pro doesn't use sound output anymore?
Hi, I have a Macbook Pro w/ Mountain Lion (10.8.2) and I don't know why or how, but the sound just stopped working. I can use headphones or my bluetooth speaker, but the speaker coming out of the keyboard doesn't sound anymore. Anyone else have the same problem or know the solution? Any advice is good. Thank you.
Hopefully one of these steps should solve the problem.
System Preference > Sound > Output > Internal Speakers
Make sure Mute is not enabled.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.

Best.

I have attempted several different choices within preferences and yet, it still won't work. The confusing part, is that when I'm at a different location, and have chosen a WIFI network there, each time I open the laptap, it automatically connects to that network. Not so at home. Thanks for any help or suggestions!
Open Finder, press Option key, select Go > Library, open Preferences and delete com.apple.network.prefPaneSimulate.plist. If it doesn't work, open > http://rys.sommefeldt.com/2011/09/04/osx-lion-wifi.html http://www.reedcorner.net/understanding-upgrade-nightmares/

Does anyone know why iOS 7 still doesn't have group messaging?
Yes, I know I can send a group message by entering the contacts one at a time. But it should be possible to just enter the name of a contact group and have it automatically send a text to everyone in that group. Every other mobile OS has this feature. Even my daughter's dumbphone does this. And when I look online for workarounds, I see LOTS of grumbling about the fact that this incredibly basic feature STILL isn't included in iOS7. Does anyone know WHY? It totally mystifies me why something so basic isn't an option.
I left feedback on it about three or four times since I got my iPhone.
Apple do not respond to feedback and since they have not added the facility ,you have your answer
and you got my response because as Ralph posted ...................

Does anyone know why my MacBook has an intermittent high-pitched whine?
Today my MacBook started making a high-pitched whine. It's like a high musical note and comes and goes. I closed as many programs as I could. Still working in Chrome (and that's what I have been on when it makes noise). It almost reminds me of a fanbelt issue.... but that's impossible, right?
Yeah, if you go to Programs > Utilities > Audio MIDI Setup
Then select where you want the sound to come from, then click on the settings cog at the bottom, and select Use this device for Sound Output, and you can select the internal speakers for System Alerts & Sound Effects if you wish. -
Recenty used a Macbook Pro with analogue out to my amp and there was no latency at all. Bought a new iMac and got a Toslink cable with adaptor and connected to same amp. There is slight latency using the digital out! Can anyone explain why? I don't really want to go back to using the digital cable because I have the surround sound setup that works well with the optical cable.
error: I don't really want to go back to using the ANALOGUE cable....

I just bought my macbook pro 2 weeks ago and have noticed that when I go to start it up, it takes longer to power up than when I first bought it. Does anyone know why this may be and of a fix for it?
Hi. It could be that the more you pile on the HD, the longer it will take to boot. When I first bought my MBP, it took maybe 30 seconds. But as I began putting more content on the HD, it seemed to take a bit longer to boot. You may also want to consider putting your MBP in sleep mode. That's what I do with mine and it doesn't hurt at all as far as I can tell.

My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Did you update to iOS 7? If yes you need to update iTunes on your computer to iTunes 11.1
If you are using iTunes 11.0 and iOS 6.x then show the left sidebar in iTunes.
When in iTunes on your computer use the View menu to View Sidebar. The device should show up there when connected. -
