On OS X Lion how do I fix headphones

When I plug them in I lose all sound and it stays gone until I reboot, even if I unplug them. How do I fix this? It worked until I upgraded to Lion.

So you post here instead of in Lion or Safari because.... you want MacBook Pro forum....?

The Reset feature adds a folder on your desktop named Old Firefox Data. I recommend hanging onto that for a few weeks in case you discover something essential that the Reset feature left behind.
This article has a list of what is migrated and what is not during a Reset, in case you're curious: [[Reset Firefox – easily fix most problems]].

Did you try to open teh fle by double-clicking its icon? If the file was made with an older version of Office, you may get that message. Try opeing PP and, from its "File" menu, see if you can open the ppt. I've foundthat often gets around that message and then yo ucan save the file from the newer version.
If that doesn't work, consider asking in the Microsoft Office: Mac forums here:

PowerPoint is not an Apple product and it seems a lot of people around here avoid Office.

HT1338 I updated my MacBook Pro with Mountain Lion and now it is starting slow and opening with some of the programs. How can I fix the problem?

I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?

Have you tried starting in Safe Mode and see if the slowness still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)
If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
Reboot normally and test.

Upgrading to lion, but serial number doesn't work. how do i fix it?

I installed Mountain Lion so that I could sync my notes with my iPhone that already syncs notes with a specific email address I use for school, but during the install it automatically set up Notes to sync w the wrong email addy. How can I fix it?

I installed Mountain Lion so that I could sync my notes with my iPhone that already syncs notes with a specific email address I use for school, but during the install it automatically set up Notes to sync w the wrong email addy. It looked in Mail, which had 5 email accounts set up in it, and for some reason picked the only one that I no longer use because it is for a school that I no longer attend. How can I fix it so that it syncs with the correct email account for notes and calendar? There don't seem to be any settings available other than to check if you want to use the basic features. It also said during the set up that it was setting up 'find my mac' but if I look on the iCloud website there is nothing showing there for finding my mac.
At this point I feel like I wasted my money paying for this supposed upgrade. I got nothing for it but frustration. It even automatically set my security settings to allow only downloads from the Mac store so the first time I went to download something I had to stop what I was doing and go correct settings first. I feel like there should be a security setting to block downloads from the Mac store so I don't accidentally end up clicking the wrong thing and being charged.

iCloud isn't syncing them on your phone. You simply added the email account to your phone and enabled calendar and notes syncing with the email provider, and the calendar and notes appear in the calendar and notes apps on your phone. You can do this with Gmail, Yahoo and other IMAP account. iCloud email is just another IMAP account, but syncs notes with Apple's iCloud server just as Gmail syncs notes and calendars with Google's server.
iCloud didnt' set up a non-iCloud account on your Mac. When you check Mail in System Preferences>iCloud, it only creates an iCloud email account. You can also add other email accounts to your Mac by going to System Preferences>Mail,Contacts,Calendars and clicking on the "+" sign on the bottom of the left sidebar. If you added these other email accounts to your Mac before you upgraded to Mountain Lion, these were simply maintained on your Mac after you upgraded.

I installed Lion on my MacBook Pro and the Finder keeps quitting - how do i fix it?

I installed Lion on my MacBook Pro and the Finder keeps quitting - how do i fix it?
Worse, i can't force quit the finder and get it to relaunch - the command won't work.
Most of the Lion software also won't work - iTunes, Mail, iCal - and only some of the preferences work.
The message:
Finder quit unexpectedly.
Click Report to see more detailed information and send a report to Apple.
Won't go away no matter if i hit Ignore or Report...
I have no clue what to do...
Any help?

Does that happen if you boot into "safe mode"? Launch the Console utility and look for messages that might explain the problem. If you see a "crash report", post its contents here.

How do I fix missing and corrupted images after update to Mountain Lion 10.8.2 and Aperture 3.4?

Last night I tried to update to Aperture 3.4 on my MacBook Pro (late 2007 / 3,1 model) and received a message that I needed to install Mountain Lion 10.8.2 first. However, there was no update in my App Store account for 10.8.2. The update for 10.8.2 appeared above the Aperture 3.4 update after I restarted the laptop and rechecked for updates. I proceeded to update Mountain Lion and then Aperture. Everything seemed to be working fine so I opened Aperture 3.4 and watched it update the database without any issues...
Upon examining the small library (of approximately 1200 images totaling about 8 GB) that I leave on this MacBook Pro specifically for testing Aperture updates, I observed the following:
I know anything can happen with stored images, so I try to create redundancy by duplicating important photos on import to an external device, running Time Machine backups and keeping memory cards stored away until I am comfortable with the integrity of the first 2 methods. I am not really worried about this specific Aperture Library on this laptop because it has become my "laboratory" for testing new updates before we apply them to our other computers.
In general, I try not to be too early of an adopter when it comes to software and updates--even though I have had remarkably few problems with Apple updates in the past. However, my success rate with Apple's products and "feature curiosity" occasionally leads me to update early! It is my curiosity that, again, has me wondering: What went wrong and how can I fix this in case it happens to something important in the future?

I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers

That does not work on model year older then 2010 and really doesn't work on any older then late 2011 models.
You will need a set of original system dvd disc thjat are always sypplied with every mac sold before Lion came out. Systems older then late release early 2011 models.
If you don't have them you kcan order a replacement set from apple by calling them. Have the serial number of you mac handy.

I just downloaded the new OS X Mountain Lion, and my iMessages status won't change!! How do I fix this?

if you set up only iMessage account, you cannot change the status, because iMessage has no status.
You should set up another service (for example AIM) with status service. Initially I didn't understand this "issue" too, but it is correct.

I-Photo won't open even though I have upgraded to OS X Yosemite and downloaded the I-Photo upgrader.
But have you run the the iPhoto Library upgrader? It is installed in Applications > Utilities. Launch it and direct it to your iPhoto library.
Which version of iPhoto did you upgrade from?
The upgrader is only necessary, if you have been running iPhoto7.1.2 or earlier.
