Macbook pro output sound has developed an echo but is okay when using iTunes

My Macbook pro output sound has developed an echo in all applications except iTunes which plays back okay.

Boot the MBP with the OPTION key down.
The display will show two HDD icons. Select the recovery partition (on the right).
From the 4 Option menu, select the Mavericks install option.
Follow the directions.

It should not, but always have a backup. Things can go wrong.

Macbook Pro Mid 2009 has a good battery but it won´t charged.

My Macbook Pro 15,4" has a 82% healthy batterie, but she will not charged. The Magsafe-Light is all the time GREEN.
The Battery has 1074 cycles.
Is there any way to bring the battery back to life?
Kind Regards, Michael

Did you follow these instructions?
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
That should work - if you can't reset the SMC, you need to get your computer to an Apple Store or an AASP.

I have Mavericks on my MacBook Pro and need to create an iDVD but it freezes when I try to open it. Also same with iMovie (8.0.6)??

Can't open either my version of iDVD (and seems Apple no longer has iDVD??) or iMovie (8.0.6) with my MacBook Pro with Mavericks? Is it not possible to create DVDs anymore with Mavericks, which is what I want to do? Creating DVDs with iDVD was what I do most?? Any help with these issues?
Thanks

Allen, Thanks for answering. When I try this, I get nowhere:
In the Finder, click the Go menu and choose Home.
Open the Library folder and then the Preferences folder.
Remove the "com.apple.x.plist" file, where "x" should be replaced with the iLife application you are troubleshooting (for example, "com.apple.iphoto.plist" or "com.apple.imovie8.plist").
Remove receipts and reinstall iLife applications
I cant find either the Library or Preferences folders. Are they invisible and somewhere else?
I search with Spot Light for them, I also do not find them....
Advice?
Thanks,
Hal

I have the exact same problem trying to use the Remote app on both my iPhone 3gs and iPad 2 with either my Mac or ATV2. My Remote app used to work on my phone - I can't recall if I ever actually used it with my iPad, but when I tried today, I got all the same results as you did (on both iPad, and then iPhone). I was using my ATV2 to play music from iTunes on my Mac and wanted to use the Remote app, but it would not connect to either device no matter what I did.

Hi, I turned my macbook pro off before I went to sleep, and this morning when I awaken. I can't seem to use the volume at all! I went to system preferences sound output BUT everything is light grey and it some-how looks like I don't have permission.

Hi, I turned my MacBook Pro off before I went to sleep, and this morning when I awaken. I can't seem to turn up or down my volume. It comes up with all the volume bars and a little circle sign with a diagonal line in the middle, like a stop sign. I have gone to system preferences > Volume > Output BUT all my volume preferences have gone all light grey and wont let me access them.
Anyone help?

My Macbook pro 2011 suddenly has a really slow bootup. What can I do?

My Macbook pro 2011 suddenly has a really slow bootup. What can I do? I did install a cannon printer upgrade and security upgrade. Not sure if it was something to do with that. Also I tried the disk utility repair and didn't improve anything. I also reset PRAM and SMC.

1. Try booting in e Verbose mode - press and hold [cmd] + [v] keys just right after the boot chord sounds till you get a black screen and white letters.
if there are some delays in the boot process - you should see where the system is stuck.
this mode is not permanent - the next [re-] boot will be normal.
2. repair permissions. disk utility does fine. Disk Warrior is better.
sometimes after half done updates (it may happen though should not) there are items that are "belonging to someone else"
3. try cache cleaner (or there are some other utilities as well - I just like SlCC more) http://www.northernsoftworks.com/snowleopardcachecleaner.html - it's shareware though the basic functionality is free for you to use.
Try caches -> deep cleaning (please read the developers site what it does) and select checkmark at all options - reply yes to the requests and after a reboot the next reboot should be as it is intended.
p.s be sure you do have backup

I have a MacBook Pro and someone has inserted a mini disc in the disc drive and I can not eject it or even get it to read, How can I remove it?

Sounds like to me that you have a bootcamp partition with Windows and have the default Windows to boot first.
I think there is a Windows Control Panel or other setting while your in Windows to set the OS X as the first boot option.
Also in OS X there is a option under the System Preferences to set OS X as the first boot option.

Hi, I am using macbook pro 2.7ghz,i7,4gb,hd graphic 3000 which i just purchased in the mid-2011 to replace my old macbook.
Everything seems fine until I reinstall the sims 3 to my new macbook pro. The video's works fine, but when i entered the create household,

it was working fine with my old macbook, and my sister who is using macbook pro 15" also works fine. I also installed the sims medieval, but the same issue occurs. i have the latest update for macbook pro sofware and also the sims.

I just upgraded to Maverick on my2 year old Macbook Pro and it has slowed down the computer terribly. All I see is that whirling circle every time I do anything. How do I go back to old OS. Terrible upgrade -- forces you to buy a new Mac!!!!

It does not. First things first have you tried restarting?
Try restting PRAM

Try booting up in Safe Mode

Also open "activity monitor" and look and see what is using a lot of processing power.

Macbook Pro starts up, has a small loading bar, and then shuts off.

Macbook Pro starts up, has a small loading bar, and then shuts off after a few seconds, but the Windows bootcamp partition works fine.
The repair disc option (using install disc) failed, and the computer cannot locate the original Mac side partition. Only Bootcamp appears under options to "restore from backup" or reinstall. The repair disc options says it should be repaired but doesn't seem to know how.
Macbook Pro.
Snow leaopard
Bootcamped with Windows.
Any ideas?

Hold c or option key and boot off the 10.6 installer disk, run DU Repair from there.
run through this list of fixes 1-8
Step by Step to fix your Mac
If it doens't work, you can recover files if you don't have any current OS X file backups, then grab what you can out of Bootcamp
Use Data Rescue installed on the extenral boot drive ($100) to read the bits of the internal (non-filevaulted) drive to retrieve OS X data files if you can't get them off manually via drag and drop methods.
Create a data recovery, undelete boot drive
If you want to clone Windows, use WinClone and another drive. However it's likely compromised, unless it something you did in Windows, like trying to create a new parttition perhaps?
Then perform a Zero Erase and install of 10.6 as shown here (on the entire drive, not only the parittions), this will give a new GUID partition table, EFI and map off bad sectors, totally fresh everything.
How to erase and install Snow Leopard 10.6
You cna use Carbon Copy Cloner to clone the new extenral setup to the new scrubbed internal drive. Recreate Bootcamp and WinClone back or fresh install Windows into Bootcamp like before. OR opt to use virtual machine software which is safer.
Windows in BootCamp or Virtual Machine?
Windows 7 can write to the boot drives GUID partition map (unlike XP), this is likely why it's borked now.

Once 10.9.1 is loaded onto my MacBook Pro and it has accessed all my files; is there anyway to back out of the relationship? I don't want my data on iCloud - how do I make that happen? Many thanks for any help.

I have a MacBook Pro and I have developed eczema on the palms of my hands. I am worried that it is an allergy to nickel. If it is is there a way to cover the metal. the hand rash is horribly painful.

I have a MacBook Pro and I have developed eczema on the palms of both my hands and I am wondering if this might be an allergic reaction to nickel. If it is, is there a solution out there so that I can still use my Mac?

-> http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3869443/
"Although none of the 25 iPhones we tested were found to release either nickel or cobalt by means of the spot test in our study, there is a report of an iPhone 5® model testing positive to nickel through DMG testing49 and Apple MacBook Pro laptops testing positive to nickel using DMG in the literature."

My beloved MacBook Pro (mid 2010) has been the victim of water damage.

My beloved MacBook Pro (mid 2010) has been the victim of some water damage. They cleaned and dried it out at Apple. Now it turns on, the fan runs, the Apple logo screen pops up, and then it shuts down immediately. Is this repairable, aside from the $1200 flat rate repair, or am I SOL? Any ideas where to start or troubleshoot? Any diagnoses?

It is better to spend money on a new MacBook Air or MacBook Pro.
Liquid damage is progressive.
Best.
