Can't delete old iTunes after Mountain Lion install

I updated my Macbook Pro (late 2008 version) to Mountain Lion and everything was working great until I tried to open iTunes from the Dock and got a message about it being unable to open, investigated the Applications folder and discovered that I now have two versions of iTunes, 10.6.3 and 10.7. 10.6.3 is in the applications folder but 10.7 is in a sub-folder within Applications. In the past I've organized apps in folders according to subject - home office, internet, graphics, games, etc., and have had no problem deleting old versions of Apple apps after system updates by either dragging them to the trash or dragging the updated version into the applicable folder and using the "replace" function. Now I cannot move either the new or old version of iTunes to trash or between folders. I'm getting a message "iTunes cannot be modified or deleted because it's required by OS X".. I've searched these forums and googled the question, and the only solutions I've found have addressed Windows PCs.
From checking the "Get info" panel I can tell that the 10.6.3 version was installed prior to installing Mountain Lion, and 10.7 appears to have been installed either with Mountain Lion itself or in a system update shortly thereafter. I tried unlocking 10.6.3 in the Get Info panel, but that didn't allow me to move 10.6.3 to the trash.
Thanks for any help.

Sure, but its the best you learn how to use the terminal. OS X is Unix and the most advanced tasks can't be done in the graphical enviroment:
1. Open Terminal (You should startet in your "home" directory, this is the default)
2. Type: mdls /Applications/iTunes.app (This will output a lot of information)
3. Look for the last keyword "kMDItemVersion", it should show the program version (e.g. "10.7")
4. From now on what to do depends on the position of the iTunes version you want to delete. If this is the most recent version you will leave this file alone. If this is an older version of iTunes you will want to delete it. So there is a decision to make.
4a. Leave this file
or
4b. Delete this file with: rm -r /Applications/iTunes.app (maybe the permissions don't allow this to do, I could not test it)
5. After that you could use the finder to move your regular iTunes version to your desired position
6. If you most recent version is in an other directory, e.g. /Applications/Music/iTunes.app, you have to do the steps above with this path
It makes sense to locate first the iTunes version you want to delete. You can get this information with the showed mdls command or with the information dialog of Finder. Click in Finder the particular iTunes icon once, so it is selected, show the information dialog (cmd+i).

Messages won't work with iMessage after Mountain Lion install

I previously had Messages Beta installed on both my Macbook and iMac and they worked great. Now I upgraded to Mountain Lion and Messages works fine on my iMac, but not on my Macbook. It defaults to Bonjour and when I enter the Apple ID info I get a message "Your Apple ID "[email protected]" can't be used to set up iMessage at this time.", and it says to contact customer support. What is causing this and does anyone know how to fix it?

HI,
I must admit to not having two computers to try this on.
The one I do have is an iMac and updated from Lion to Mountain Lion with Messages Beta still active in the Lion build and I did not have any problems.
I can see that the iMessages servers could be getting confused as you are trying to use the same Apple ID on the MacBook as is in use on the iMac.
Try going to the preferences in Messages on the iMac and Disabling the iMessage Account whilst you set up the nmame in a MacBook

Problem with mail after mountain lion install

Mail has become sluggish to locking up after Mountain Lion install. I get the color wheel each time I start typing in an address to send an email. I also get the wheel when i am typing an address or name in any web page in Safari. Is this a Mail Problem or an Address Book problem?

It sounds like your computer needs to be cleaned up. Have your repaired permissions or cleared caches since you got the computer. Often times when upgrading operating systems permissions get screwed up and it causes issues. Go to disk utility in your "other" folder in applications. Select disk utility, then on the left hand side choose Mac HD then click REPAIR permissions in the center section. Wait for it to finish, restart your computer, then test.

can any one help?

So, the videos won't play properly in iTunes, but play properly on the iPod?
Make sure you have the latest version of Quicktime installed (http://www.apple.com/quicktime/download/).
If that doesn't work, try going through the steps in this article: http://docs.info.apple.com/article.html?artnum=303706.
Video playback can be messed up by a lot of different things. That article covers a lot of them.

After Mountain Lion install, my iMac powers off instead of just going to sleep. Help? Thanks.

After I installed Mountain Lion on my 2009 iMac, it will power off after I don't use it a while. It used to just go to sleep, I'd shake the mouse, and it would come back up. Now it powers off and I have to power it back up every time.
My Macbook has NOT had this problem since Mountain Lion install. It is fine.

Do these resets to clear errant commands:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Trackpad issues after mountain lion install

Since my Mountain Lion install, the trackpad on my 15" MBP will track, but won't select anything. Hot corners aren't working, the dock won't appear, etc. Anyone have any suggestions?

Got similar issues, no notifications and no switching between full screen apps (4fingerswipe). Some swipe features work, no secondary click in bottsom corners...Trackpad operational under Mountain Lion a total nuisance compared to Snow Leopard...PLease Apple, show some respect again to your faithfull customers and show some response!

Video won't play in iTunes

It looks like it downloaded fine but it will make it seem like i didn't press any buttons and won't play in iTunes

Bingo! I was having the same issue where I could not play music videos in iTunes. The solution per Russa was to switch the speakers to "computer" only and not the "multiple speakers" or Airport Express options. THANK YOU so much for the solution! It was driving me nuts. I tried a re-install to no avail. I ran Onyx to fix permissions and other utility repairs and anything else I could think of. Funny how such a simple option could cause a glitch like this.

After Mountain Lion install, internet videos stop playing back after only a few seconds. Multiple browsers are affected.

After I installed Mountain Lion, videos streamed from the internet will stop playback after a few seconds of play. Multiple browsers are being affected.

I have this same problem, and I did a clean installation.
Hardware:
2009 MacBoook Pro 17" 3.06 C2D; 4 GB RAM, 256 Apple SSD
While loading the browser is quick starting up, I notice a delay to open any website, like it's preloading the entire page versus just loading. Safari seems like it's a bit sluggish overall with loading web pages.
Did a internet speed test and my U/D rates are the same after the upgrade.

Safari 6.0 won't Play .m3u8 files under Mountain Lion

I have embedd some streaming video in my web page, but it won't play in Safari 6.0 under Mountain Lion 10.8.1.
The streaming video shows just fine on my iPad 3 and on my iPhone 4, and it shows just fine in Safari 5.1.7 when I boot up under an earlier system version. In 10.8.1, however, all I see is the black "loading" bar, but nothing ever happens.
Any help will be appreciated.

I am getting the same issue.
In the new Mountain Lion update 10.8.2 it says that it fixes safari so that you can have it automatically open safari and it will open all last windows.
I did the update, I don't have that option still under my general settings in safari, when someone else did the update and they have that option to reopen last windows when opening safari...help please

After Mountain Lion installed, 27" late 2009 iMac won't sleep

As the title says.....
Worked fine since new, but with Mountain Lion, it won't auto sleep. I have a numbe of iProducts, but only this one isn't working. Energy saver settings are fine.
Desired behavior is after a few minutes the screen goes dark, then spool down after 15min, but it never happens. It will sleep if I hit the power button.

trying a clone after all due to this discussion https://discussions.apple.com/message/20938457#20938457
