I don't know my admin password?!

I have somehow changed my admin details and now I can't update or load any software. What can I do? I don't know if the user or password is wrong. When I try to authorise any changes the dialogue box just shakes and nothing happens. Is there anything I can do?

restart the computer holding down the command+R keys, this boots you to the internet recovery
once booted to this if you look on the main menu bar you will see the word utilities (not mac os x utilities) click on this
choose terminal from the drop down menu which will open a small window that already has text in it
type the words resetpassword all together w/ no space between and in lower case letters then hit return
this will open the password reset window
under volume choose mac HD
select your name from the list of users
type in the new password 2 times in the spaces provided and hint if you want one then click on save
hit the red circles on this window and the terminal window
restart the mac and at login window use the new password
you will get message regarding the login keychain choose the option to create new keychain and it will be reset!

Who did you purchase the MBP from. They should have the password.
An early 2011 MBP probably came with Snow Leopard. Use the original OSX disks and reinstall 10.6.
There is a possibility that it came with Lion (10.7). In that case boot the MBP holding the OPTION+COMMAND+R keys. That should connect you to the Apple servers and install the original OSX.
Ciao.

HT4798 Help - I bought a nearly new iMac but I don't know the admin password, is there a default? Trying to install software and it needs the admin password.

I have wanted to move to a Mac for some time now as I am a keen photographer, I bought a very nice Imac 21.5 May 2011 model OS Lion and it is wonderful.
Just tried to put my Adobe Photoshop software on and it asks to log in to Admin and asks for the password, I have tried the 'link to your Apple ID' but it doesn't seem to want to work.
Any help out there?

Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     When the menubar appears select Terminal from the Utilities menu.
     Enter resetpassword at the prompt and press RETURN. Follow
     instructions in the dialog window that will appear.
     Or see Reset a Mac OS X 10.7 Lion Password and

I am trying to set up a co-worker's email on her iPhone and I don't know what her password for Thunderbird is and neither does she. Can I get the password?

I am trying to set up a co-worker's email on her iPhone and I don't know what her password for Thunderbird is and neither does she. Can I get the password somehow, or what do you recommend?

There is no password to Thunderbird. The password you need is to the email account. Contact the email provider for password reset.

How do I change my icloud email when don't know the old password after I have changed my apple ID email address and the password? icloud is still online with my old email address!!!

I got a new phone but backed it up through my itunes, and when I tried to use icloud it kept telling me I have forgotten my password, when I really really didn't. So I went to settings > itunes&appstore and changed my password, but also changed the email address too while I was at it, since I've always wanted to change it. But now here's the problem. My iphone's icloud is currently logged in with my old apple ID email address, which seems to not work with the new password, so I can't log it or even delete the account off my iphone. And ovbiously, I don't know the old password that I have "forgotten", as my phone tells me. There seems to be no way of changing the icloud account now.... What should I do?!

So what was the solution. I have a similar problem on all of my devices now

My iCloud email address and my apple ID are different. I would like to change my iCloud to be the same as my apple ID. However I don't know my iCloud password and don't use the email address it belongs to. When I try to change the password, apple brings me to a page to reset my apple ID password (which I know and don't want to change). I have even tried to delete my iCloud account completely to start again but am not allowed without the iCloud password (which I don't have) there doesn't seem to be a place to change the email address of iCloud. What can I do?

This is the answer that I had expected, so in this case you could only change your gmail.com address to another providers email addres e.g. outlook.com, yahoo.com, etc., but you won't be able to change the gmail.com address to a icloud.com email address. Apple just won't let you do that.
Your iCloud account with @icloud.com email address and you Apple ID with gmail.com address are already connected and as I said before, Apple just let you merge this two IDs together.

You cannot. That is the point of encrypting the backup.

I don't know my administrator password and I want to download an antivirus. I also don't have the MAC OS install CD either.

I don't know my administrator password or have the MAC OS install CD. How can I download and install software without either of these?

What version of the Mac OS are you running?
Generally anti-virus applications are either useless or actively bad for your Mac. ClamXAV is an exception to this rule.

HT6030 Don't know my keychain password??

I just installed this piece of software on my MacBook Pro, and I don't know my keychain password! Each time I try and get on an application, like chrome or safari, I am blocked because I can't get the pop-up window off my screen! Help???

Welcome to the forums!
In Utilities > Keychain Access you should be able to select the Login keychain (even though it's locked) and then File > Delete Keychain "Login". Then quit, log out, and log back in and a new login keychain should be created.
If this fails, you can manually delete the login.keychain from the ~User/Library/Keychains folder. Then log out, log in, and go to Keychain Access, Edit > Keychain List, click the + to add a keychain, and select the login keychain.
With your new keychain, next time you run Safari it will ask for access to your keychain, you can click Always Allow and you should be set.
Hope this helps...
