Can't log into Messages on Mac

Today, Messages began to give the error "The registering device does not have the appropriate credentials." The error only began today. I use the same Apple ID on my Mac, iPhone, and iPad. Apple ID and password have been verified on all devices and at iCloud.com.

I had to reset PRAM, problem solved.

Can't log into Gmail using Mac Mail client

Wow, after upgrading Lion for iCloud and upgrading my iPad2 for IOS5, I can no longer get Gmail on either one using Mac Mail as the client. I get a little triangular caution symbol next to the Gmail account in Mac Mail. I tried deleting the account and recreating it, and when the account setup wizard tries to connect, I get the following:
"Logging in to the Google IMAP server "imap.gmail.com" failed. Make sure the username and password you entered are correct then click Continue. If the information isn't correct, you cannot receive messages"
This doesn't make any sense, since the account has always worked in the past. Simultaneous to that, I have started having the same problem on the iPad, which never had trouble logging in before either.
Anybody else encountering this?

Can't log into CC after Mac 10.7.1 update

This only seems to be happening on my tower after the update yesterday. Laptop seems to be working fine.
The Creative Cloud desktop app just shows a blank white rectangle. I've tried reinstalling to no avail.
When I try to open any CC app (e.g. Photoshop CC), it says I need to log in. When I try I get an error message like the follwing (differnt error codes each time I try).
Error
There was an error with this action. Try again later.

Arpit--
Attached are screen shots of by CC Desktop app and the error message I get after trying to authenticate when opening any CC app (Photoshop in this case).
Also, I was being dumb...I'm running the very latest versions of OS X (was loking at the listings for "MacOS X Updates" in stead of further down the installation list at "OS X Udates). The update last week was the "OS X v10.8.5 Supplemental Update" that I installed on 10/10. As I think I mentioned...I updated on my laptop as well and can still access my CC apps there...I'm not sure I've logged out of CC and back in since the whole password thing though.

I can't log into messaging on my Imac

I can access Itunes and any other applications that require my Apple Id password but not Messaging. On my Ipad Mini I have no trouble with Messaging.

Well I got it working again simply by shutting down my Imac and restarting.

I can't log into my mobile me account from my lap top. Is it because of my operating system? I'm on Mac OS X 10.6.8?

I can't log into my mobile me account from my lap top. Is it because of my operating system? I'm on Mac OS X 10.6.8? Every time I try to enter my data in on the control panel I get an error that says; "Your MobileMe member name or password may be invalid. Please enter a different name or password." I know the name and password is correct because I can log in via the Web.

Apple discontinued it on June 30, 2012. Many of its services are now provided by iCloud; anything which connects specifically to MobileMe won't work.

I can't log into iMessage; I get the message "Unable to verify email because it is already in use".

I have iOS5 installed on my iPad and iPhone. I can't log into iMessage on my iPad as I get the message "Unable to verify email because it is already in use". Can anyone help me solve this?

I've found the answer to this (at least for me)!
The problem is I have 2 AppleIDs. One from before MobileMe which I use to make iTunes purchases (which is linked to my @me.com email) and the second is my MobileMe email address used for MobileMe syncing.
Each AppleID has to be linked to a separate email address. Because my iTunes Apple ID is linked and verified to my @me.com address. My @me.com AppleID address can't be verified.....quite confusing at first but starts to make sense once you get your head around it!
See this thread for futher explanation: https://discussions.apple.com/message/16414211#16414211

Created three new users without Apple IDs and they can't log into either of my Macbook Pro or Mac Mini running Mountain Lion.

I have created three new users without Apple IDs and they can't log into either of my Macbook Pro or Mac Mini running Mountain Lion. These accounts are for my kids and originally were setup with parental controls and time constraints. Thinking this was the problem I removed the time constraints, removed the parental controls, deleted and re-added them, and made them standard users. I have reinstalled, used disk utility to repair permissions, and made them admins. Any help is appreciated.

Users don't need Apple ID's. That's not the issue. Have you tried repairing permissions their accounts?

Repairing User Permissions in OS X Lion
You’ll need to reboot to perform this, and then use the same resetpassword utility that is used to change passwords in Lion, but instead choosing a hidden option.
When you use the Disk Utility app and Repair Permissions — it doesn’t actually repair the permission settings on folders and files in your Home folder where your documents and personal applications reside.
In Lion, there is an additional Repair Permissions application utility hidden away. This tool is located inside boot Repair Utilities. Here’s how to access it.
Restart Lion and hold down the Command and R keys. You will boot into the Repair Utilities screen. On top, in the Menu Bar click the Utilities item then select Terminal.
In the Terminal window, type resetpassword and hit Return.
The Password reset utility launches, but you’re not going to reset the password. Instead, click on the icon for your Mac’s hard drive at the top. From the drop-down below it, select the user account where you are having issues.
At the bottom of the window, you’ll see an area labeled ‘Reset Home Directory Permissions and ACLs’. Click the Reset button there.
The reset process takes a couple of minutes. When it’s done, quit the programs you’ve opened and restart your Mac. Notice that ‘Spotlight’ starts re-indexing immediately.

Cannot log into Messages Mac OS 10.10 Yosemite.

Just upgraded to Yosemite. Cannot log into Messages because it is asking me for "talk.google.com Password". This references my gmail. The window will not accept either my Google password, or my Apple ID password.
What's up?

I have just checked the base of my iMac and the serial number is different to the serial number in About This Mac. Looks like a trip to the Apple Store is needed

TS4185 I can't log into FaceTime or Messages, checked that my ID and password are correct, checked that settings are set correctly. Could it be that latest OS download changed my configurations that disable access?

Update to above question:
Hello All,
To anyone with the same problem described above, on THEIR iPad (if it is running iOS 7.0.2):
Go to Settings; Mail, Contacts, Calendars; DELETE your *******@btinternet.com e-mail account, that you originally set up either using 'Other', or the 'BT' option which I am sure was in the list previous to the iOS 7 update.
Then ADD a NEW account choosing YAHOO from the list of options. DO NOT USE 'OTHER'.
Enter the correct details just as you (almost certainly) had already done in your previous attempts using 'other'.
When you see the 'verifying......' and 'the blue ticks' you should be able to exit settings and open your mail app and then receive all your 'old' e-mails again, AND be able to SEND as well.
All my 'old' e-mails, were NOT found in the 'old e-mail' folder though. THEY are still in my inbox.
So this fix worked for me.
After I deleted my account from 'OTHER' and put it in Yahoo, I like other people also ended up with more folders.
I hope this works for you on YOUR Apple devices.

HT1206 I can't log into the Itunes store. I type in my Apple ID and my password and the message "This Apple ID cannot be used for the iTunes Store." "Enter another Apple ID." I need help on fixing this.

Yeah I'm starting to see a ton of forums posts right now about the same thing :/ I wonder what's going on

Why do I get iCal error messages on my iMac saying that it can't log into my Gmail account and that the password may be incorrect - when the password is correct?

I recently changed my Google email password and now I keep getting the bouncing iCal icon telling me that it can't log into my gamil account. When I go to calendar.google.com as instructed and enter the new password it does not solve the problem.
Thanks

I have the same problem and can't get an answer form Apple Tech Support

Still can't log into my iTunes account.

Still can't log into my iTunes account to edit my account info.

An unknown error occurred(-2).
Could someone else try and edit your account info and let me know if it's working.
Thanks.

I too have the -2 error code.
Any ideas what it means?

I can not log into iCloud

Please help - I've upgraded to ML 10.8 (and also 10.8.1) and i can not log into icloud.
I get an error saying "You can not log in at this time". I have no hair left on my head because I've pulled it all out!
Now, there are many published fixes for this, but NONE work. I've tried everything I can find:
Yes, I have an AU and US apple ID, and both dont work
I installed ML from a fresh disk wipe + install. No baggage from previous OS's.
Everything is standard, no tricky fixes or apps
No Little snitch installed
Have deleted the ~/Library/App Support/iCloud folder
Have deleted any preference files
Have opened up the permissions on the ~/Library/Caches/iCloud folder
Have reset keychain
Have deleted all references of any @me or @apple accounts
Have re-installed the ML OS from a DIFFERENT bootable USB stick
No proxies, SOCKS, or mods to network
Plain old home WIFI network, never had a problem
Have icloud successfully set up at work (QC 2.8GHZ Mac Pro 2010), on my iPhone, iPad and Macbook Pro - Zero issues
The mac having problems is a 2008 iMac, Core2Duo 2.8ghz Intel w 4gb 1067mhz ram) - Runs well, use for design.
Is it a problem with the iCloudHelper process not having sufficient permission to write to the iCloud user DB? or the Accounts folder?
Have looked into console, and when I try and log into iCloud, I get these three errors. Same every time, no matter which apple ID account you use:
1: AOSKit ERROR: (System Preferences[352]) AOSKC ([email protected]): Failed to store key, couldn't add kc item, error 100013 (service=iCloud, dsid=146089737)
2: AOSKit ERROR: (System Preferences[352]) AOSKC ([email protected]): Failed to store account info key (dsid=146089737).
3: AOSKit ERROR: (System Preferences[352]) Failed to store account info for appleID=[email protected]
Please help! Is this an incompatibiloty with the iMac problem, or a ML problem?
Much appreciated
Rick

Where EXACTLY are you trying to log in to it?
Through your web browser at iCloud.com?
Or through the iCloud system preferences pane on your Mac?

Can you log into CC on two computers on the same IP address at the same time?

Can you log into CC on two computers on the same IP address at the same time? Because i accidentally opened both and was wondering if it will affect my membership or deny me access to CC. Thanks
