My MacBook Pro has no audio. Sounds preferences showing output is Optical digital-out port. How do I change this to built-in speakers?

I experienced this same problem yesterday on my MacBook Pro, still searching for a solution, several other posts here indicate people have been experiencing this since at lease 2007. I have yet to find a clear solution.
It appears that occasionally inserting headphone causes this, it turns on the Optical digital-out port feature (red light glows inside the headphone port) and takes away the internal speakers option. Restarting did not restore it, but for some reason after sitting asleep overnight the sound started working again and the internal speaker option return in the Sound - Output Window, and the Optical Digital-out option went away.
Here is another post with some ideas on this

If you see a red light in the audio output port, then the internal switch is stuck. Insert the earphone plug a few times and see if you can trip the switch. If that fails, insert a cocktail stirrer and the like and jiggle it around inside. If that fails, take it to an Apple store and have the technicians at the genius bar do it for you.

I have 3 different itunes accounts and would like to combine them into just one for all my devices, a macbook pro, an iphone 4S, an older IPOD, and a ver sion one Ipad. how can i do this on all devices ?

i have 3 different itunes accounts and would like to combine them into just one for all my devices, a macbook pro, an iphone 4S, an older IPOD, and a ver sion one Ipad. how can i do this on all devices ?

i had one for a long time, then when i got the ipad i didn't realize they would all still work under one so i set up the second one on that
then when i got the new iphone i put in the info for the first and main one from my mac pro and it would not work at all, and i knew it was right, then it asked me to create a new one or i couldnt finish the setup
hence why i have 3 now
hard to believe you cannot combine into one
oh well, i will just make them all accessible for all 3
thanks

My macbook pro has stop playing sounds

I have a relatively new macbook pro and the sound isn't working there is no supposed "red light" problem that most seemed to have, the volume icon shows at full and nothing plays, I went into system preferences under sound to check if everything was alright and it was.. my mac is only less than month and hasn't been dropped or damaged in any way...? any help

try to reset the SMC
- turn the computer off and make sure the power is plugged in
- then on the left side of the keyboard, hold down the shift, control, and option keys
- while they are held down, press the power button.
- the computer should not turn on if this is performed correctly.
- after that, let go of everything and turn the computer back on
- also, what applications are you trying to play sound through? Make sure the sound within the app or player is turned up

My macbook pro won't open games that weren't purchased in itunes store. How do I change the preferences for downloads?

My macbook pro refuses to open games if they weren't purchased from the apple store. Message says my security settings prohibit opening game. How do I reset the security settings?

Not sure about where it is or even it this setting exists on 10.6 but on lion it is in the security & privacy section of system preferences. You have to click the lock icon and type in your admin password then select "Anywhere" in the "allow applications downloaded from:" area.

HT4628 My MacBook pro has suddenly stopped connecting to Internet and says that "no air port card installed". Please help

It was working all ok until last night, just tried connecting through cable but I am still unable to do so. How do I fix this? Any help?

What do you mean by "tried connecting through cable"? I can think of two different things you might mean.
It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort/Wi-Fi menu bar item to turn AirPort/Wi-Fi off, then on again.
2) Try to select your Wi-Fi network from the AirPort/Wi-Fi menu.
3) In the Network panel of System Preferences delete the AirPort/Wi-Fi item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort/Wi-Fi connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

After upgrading recently I got this message: "The file 'iTunes Library.itl' cannot be read because it was created by a newer version of iTunes." The music/video files are still on my MacBook Pro. Is it because I'm still on 10.5.8? How do I fix this?

For your reference I’m using a MacBook Pro running 10.5.8. Several weeks ago on a Monday I received an upgrade for iTunes. When Tuesday arrived I attempted to log in so that I could download the latest freebie song(s). I was met w/this message: “The file ‘iTunes Library.itl’ cannot be read because it was created by a newer version of iTunes.”
The music/video files are still on my Mac (I’ve verified that via Searchlight), but I’m unable to open the program. Since I know that 10.5.8 is rapidly becoming prehistoric, could it be that the newest iTunes isn’t compatible w/this particular OS? I’d like to switch up, but understand that the newest OS won’t work on a Mac of this vintage (6 years old). In addition, my Adobe products (all CS2) won’t work w/anything newer than 10.5.8, so I’m reluctant to go to a newer OS (I just can’t afford the Adobe upgrade $$$ @ this point).
Is there any way to get a download of an “old” iTunes version? If there were, I’d simply refuse any future upgrades until my personal economy allows me to stop working as if it were 2006. Please advise, somebody!

I don't know how you received an upgrade for iTunes. You make it sound like it was sent to you. At most your computer will tell you of a new version and you tell it to download it and install it. However, a computer will not do this for a version which is incompatible. iTunes 10.7 came out a few weeks ago but your computer would not notify you and even if it did, 10.7 would refuse to install on your computer. So this part isn't making a lot of sense.
Two ways to get the 'newer version' message. One is to open your library on a computer running a newer version, and then try to open it with an older version. Usually happens when the library is on an external and used with multiple computers. The second way is if you have multiple versions of itunes installed on your computer.
The newest (and likely the last) iTunes for OSX 10.5.8 is iTunes 10.6.3 which has been out for quite a while.

The wifi on my macbook pro (lion) is ridiculously slow. the wifi on my pc works perfectly though. how could i fix this?

So I recently bought my MacBook Pro, about three days ago, and the wifi connection is horrible. I can barely access anything on the internet. I tried using my PC laptop, and the wifi worked very quickly, so the problem definitely isn't my wifi connection and has to do something with the MacBook Pro. What would be the problem? And how would I be able to resolve this problem?
By the way, I am using the OS X Lion and this is my first Mac ever.

I think the other devices are fine. I'm not sure. It usually only happens like a couple days out of the week. I do know that the network I'm using when I click on the wifi symbol at the top of my screen doesn't have a padlock on it. It IS MY network that is at my house, but maybe that has something to do with it.

My Macbook pro 13 inch is stuck on a gray screen with the apple logo, how do I fix this?

Sooo, I was using my laptop for a while and the charger was kind of broken, it was dip in and out, and slowly I got a "Service Battery" notification. I updated my system and now everytime I try to boot up my computer it'd show a gray screen with the apple logo and a loading bar with a circular loading icon but it never actually boots up. It stays stuck at that loading screen. I don't think it's because I uploaded my system that it happened, but I'm wondering if it's because I didn't change my charger/battery, and I'm wondering if I have to get the harddrive changed or is there a way for me to recover my files and whatnot without having to whip it. Please help, and thanks in advice to any help offered.

Dwaniej,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get past the grey screen now?

My repaired water damaged macbook pro has no audio with the icon greyed out. i tried all the suggestions but nothing seems to work. however, on my external clone, the output does work. any ideas about this?

I tried reseting the pram, reinstalling the software, plugging the headphone jack in and out, deleting playlist but nothing works. on the external clone, the output works with noise but still no input device.
can i use a sound card instead?

If you just had the system repaired for water damage what did they replace? If it was the Logic board then all parts should work and if they don't, like the sound, then they didn't fix it correctly and you should take it back to them for a proper fix.

HT1420 My current Macbook Pro has always been authorized with my apple ID now it is not and I cannot delete this computer nor add it to my account?

I have recently purchased a new iPhone 5S and was looking to make a custom ringtone. I have always had this computer authorized already and I can play all my purchased content in iTunes currently. However, when I sync it is requesting I authorize this computer. I do that and it says I cannot because I have computers authorized already. I followed apple's instructions to deauthorize this computer however, it is saying this computer is not authorized. Someone please help?!?!?!

I would restore the iPod to factory defaults/new iPod on your computer and start over. It appears the iPod is associated with another account. Any media that came with the iPod does not belong to you and di not transfer with the iPod hardware.

Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
