MBPro 17 Intel Core 2 Duo Audio only works with the headphones?
There is a red light constantly emitting from the headphone socket?
I can not listen to sound unless headphones are plugged in - when taken out I get a red light and the volume controls kets seem locked?
Please help!

Hi Kitty.
Seems to be quite a popular problem. In another post, I posted the following.
"The red light is the data signal that is transmitted if you plug in an Optical Audio device such as surround sound speakers. I had the same problem for a short while with my 17' MBP. Sound was working fine from my built in speakers but I plugged in some earphones to listen to something that I did not want the rest of the office to hear and after pulling the hearphones out, the optical signal (red light) was being transmitted. The switch Cessna is referring to is the switch that is triggered inside the port that tells OSX that earphones/optical audio device is plugged in and to shut down power to the built in speakers. When the device is un-plugged from that port, the switch should get triggered again and power up the built in speakers and disable the optical light signal. Perhaps there is the slightest defect on the earphones you are plugging in that are preventing it from triggering the switch when the earphones are un-plugged.
Try a different sent of earphones to maybe trigger the switch if you are uncomfortable with the paper clip solution."
That seemed to solve the problem for that user.

No, you need a Mid 2007 iMac 7,1 or newer to run Mountain Lion.

I have a macbook pro 2.4 ghz intel core 2 duo 2010 13" aluminum with 8gb of memory and a 250gb hard drive running version 10.6.8 with safari 5.1.4. Safari will open up intermittently on its own. System preferences and the dock isn't set up to start safari. Can't figure out why this is happening. Had reloaded system from scratch and noticed this happening lately.
Remove iAntiVirus, then reboot, see if it's better.

Hi everyone. I have a MacBookPro3,1 Intel Core 2 Duo, 2.4 GHz with 4GB Ram — will it run Mountain Lion? My hard drive has 615 Gigs of free space. If so, is it worth it for me to upgrade? Will all the new features be available to me. Presently I am running Mac OS X Lion 10.7.4 (11E53). I heard that there is an update 8.1 out there with developers as of yesterday.
Thanks.Hi John.
Yes, an erase and install sounds like a good idea. I just need to check my Adobe CS5 software to see if I need to upgrade the suite. If that is the case, then I may need to put it off for a bit. Thanks so much for your help.
I have a newer MacBook Pro at work, but usually wait to upgrade it, till I've been running it at home on my personal computer for a while. Would hate for it to mess up my production schedule.
Thanks again and have a good evening. -
Where can I find directions to replace the internal HD on a MacBook Pro (Intel Core 2 Duo, 08/08)? Considering the age does it matter ATA-300 or 150?

4 DIMMFrom my personal experience, I wouldn't go for an Integrated card. This is one of the most important components for Photoshop, so invest in a decent graphics card (ATI or NVidia). It doesn't have to be a really exepensive one - I have been using ATI Radeon with 256MB of RAM on my Dell Studio for almost two years and it still rocks! (even when I work with 3D in Ps CS5 Extended).
I would also invest in more RAM (this can be added easily - I bought extra 4GB as my Studio came with 3GB).
I wouldn't worry about the processor - I'm on Intel Core 2 Duo - and it works very very well, it's very quick which is very important as I'm training Photoshop.
I hope this helps. -
I have problems with outgoing call no audio, only works with speaker. I bought my iphone on december 2011.
Had the same problem, no audio on incoming or outgoing calls and only could hear the conversation of the call if I put on speaker. It seemed to start after I did a recent IOS update this past month. I tried restart, reset and restore of my iPhone but nothing changed. It appears not to be a software issue but a hardware problem. I got my phone this past summer so it was still under warranty and got it replaced.

Get the new keyboard at eBay and replace by yourself may be cheaper way, though you're required higher skill and well know about MacBook Air.
