Right speaker on Macbook Pro (with Retina) not working..

Bought Macbook Pro with retina display yesterday and just noticed sounds is only coming from the left speaker. I've checked on system preferences and when I turn the left hand speaker down there is no sound. Is this a manufacturing error or something I need to do?!

Hi,
Not a lot to go by from the lack of detail in your post, however let me try to help.
[note I may not follo up on your response - just a heads up as i'm very busy [ arent we all]]
Anyway, I bought a HP Pavilliion 500 the other day. and was stoked - awesome machine at a great price locally.
So after plugging in my Altec Lansing 6.1 surround sound speakers using the brown/black/green colour coded input plugs on the back of the PC's audio card (built in) - to correspond with the cables on thealtec lansing, I noticed that 2 speakers were working at the same time, and another speaker did work at all.
I spent about an hour or 2 pulling hair until I finally turned everything off, then plugged it in, then turned n the speakers and then the PC - voila - the speakers were working, one thing I had to do though was move them around as the front right speaker was now the middle etc, no biggy - just moved the speakers around...
PS: there was a siding button on the back n my speakers that allow full 6.1 or stereo - which I hd to change to get it to work.
Also on the altec lansing model I have I had to adjust the surround knob on the main speaker control to #10 for surround for the speakers to work individually.
I hope it helps you somewhat?
Check what inputs you are using. Check the inbuilt sound control software, in my case it was DTS Audio Settings, which allowed me to tweak things a bit.
Sometimes yes it is hardward,but when you know your have "known good speakers"as I did, and a brand new PC - which in theory should handle the speakers I am using, then it can be a combination of trial and error to get them working...
I gues you have the latest drivers, and if you dont have any great input options (ie: if you only have headphones socket) and are using stereo - ty some headphones? - as sometimes it can be the cable socket itself which is just built slightly different so the speakers dont all come thourgh like they should...
Cheers

Does the new MacBook Pro with Retina not support Bootcamp?

I've read a couple different reports claiming that Bootcamp is not even installed on the new Retina MacBook Pro. Is this true?

I got Win7 loaded via bootcamp on the new MBPwR. I think when it first came out, there was issues connecting to download the bootcamp drivers but this has been resolved. Bootcamp wizard will ask for an os iso image, usb drive. It will wipe the usb drive. With Win7 Home and the bootcamp drivers, it took approx. 4.33GB on my usb drive. You can then choose how large of a partition you want created for windows. Once windows 7 installer loads, you'll see the bootcamp drive but won't be able to install until you have windows format it. After windows load, it'll default to vga resolution (think 800 x 600) until you go in and install the boot camp drivers from the WindowsSupport folder of your usb. It'll load all of the right drivers including nvidia display, touchpad, etc. Everything seems to work well and you can even run it in full resolution (2880 x 1800) but text will be small. It'll also still push 2 external displays (I have 2 acer 23" connected via hdmi and a thunderbolt to dvi) along with the retina display. Only concern is that it runs hot in Windows. Got my cpu core temps to 203 degrees F with when streaming an hd youtube clip, installing cs6, and typing a word doc. You can see the mac os partition from windows 7 and even open files but it didn't allow me to save the changes since it said I didn't have permissions to do so. Back in OS X, if you want to read and write to your windows partition, you'll have to load up NTFS-3G, macfuse and a ntfs-3g patch for lion.

So, my Macbook Pro with retina display only prints in black and white. My printer, officejet 4620 series [555DE4], is not the problem. I want to know how to be able to print in color as well??

Did you download and install the Windows Support software? If you did, did you use the Boot Camp Control icon to set up the trackpad how you want it?

I have purchased a MacBook Pro with Retina display, but it will not arrive within 30 days of my purchase. Does this mean I will not be able to update the software to Mountain Lion?

As already stated, I have recently purchased a MacBook Pro with Retina display. It will arrive in 4-5 weeks so I don't assume it will arrive in less than 30 days. I would like to know wheather I will still be entitled to a free softwere update to the Mountain Lion. The laptop will ofcourse be completely new and recently purchased, so it would be very disappointing if I am not entitled to this update. Please let me know if you know anything about this or have any assuptions. Thank you

You can call apple if you need reassurance, but they will not turn you down on the free upgrade just because you have not received your computer by day 30.

My MacBook Pro with Retina display displays power point and not other windows when connected to a projector

My MacBook Pro with Retina display displays power point and not other windows when connected to a projector. Can anyone help out please?

You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

PLEASE HELP!!!!!

You could try updating your apple TV and then restarting it. Bit of a guess.

MacBook Pro with Retina display not transferring new songs.

I have the 15" MacBook Pro with Retina display. When I plug my iPod classic (4th gen) into my MacBook, my iTunes does not display that it has been connected as it does with my iPhone. However, screen on my iPod shows that it is connected. Also, my newly purchased songs are not getting transferred from my iTunes to my iPod.

What have you tried so far in terms of troubleshooting this issue? Are you plugging the iPod into a high powered USB 2.0 port on the back of your Mac? Have you tried another USB cable just in case?
What happens if you try to reset the device with it still connected to the Mac?

Have you carefully worked through each and every single suggestion in this Apple support document?

My eyes just glazed over...Please in the future break down each of your issues with paragraphs separated by two carriage returns. It would be much easier when trying to address your issues.
Go to Apple menu -> System Preferences -> Keyboard and Mouse -> Mouse
And edit your mouse settings to do what you want it to do.
Secondly, this is not the place to vent. If you have a complaint, there is:
http://www.apple.com/feedback/
or http://www.apple.com/contact/
We are just end users here helping other end users.
Third, from my understanding, it would appear you are concerned about the noise the hard drive makes when it falls asleep? Why not put your machine in screen saver mode instead? Apple menu -> System Preferences -> Energy Saver turn off all Energy Saver settings, or set them to run Never.
Fourth, if your machine was purchased just a few days ago, you may still be able to get an exchange from the store, quicker than you can get a repair done. You may want to look into that possibility.
Fifth, it does appear you found the Logic forum. I would persist in asking there how to solve your technical issue with Logic regarding the audio. It may be you don't have to do anything special to the hard drive. Remember audio can be transmitted by wire, avoiding ambient sounds.
Good luck!

Why will some CDs not work properly with my Macbook Pro with Retina display?

I have the external CD drive for the Macbook Pro with Retina display, but I'm finding that some CDs will not run their applications properly. However, on the older editions of the Macbook Pro (for example, on the 13"), the programs run fine. Is there something I can download to fix this problem?

When the MBP-R does not run CD applications "properly", what does it do?
Is it possible that the applications that do not run properly are incompatible with Mountain Lion? For example, might they be old PowerPC applications that relied on Rosetta to run on Intel CPUs?

I bought a macbook pro in boston on October 25th, can I exchange it for the Macbook pro with retina. It has not been turned on - only the box has been opened.

I've never turned on my new macbook pro but I want to exchange it for the new Macbook pro with retina display. Is this possible. I have the receipt. Box was opened.

No - you have 14 days from date of purchase to exchange or get a refund. That should have been on your receipt somewhere.
I'm afraid that you're just going to have to sell your computer, somehow, and put that money towards a new one.
Why in the world did you buy what you didn't want?
