Mail doesn't recognize password after upgrading to Mountain Lion

After updgrading to Mountain Lion:
The gmail account in Mail began to ask for its password. it is preseent [in dots]; when i click to continue, dialog box indicates it doesn't recognize it.
i had time to to go over details in a gmail help page with details (port numbers and other things).
I decided to start over.
I deleted the account in Mail, system preferences, Accounts, began anew. Later I deleted inactive Gmail from  menu, Mail. Contacts & Calendars.
Reading some interventions in Communities mentioned the Key Chain. I had changed the Gmail password while using an older Mac Book. In June i purshased a MacBook Air and had Apple migrate my files from the old to the new mac. Mail had not password problems until I updated to Mountain Lion, which I thoroughly enjoy.
I'm at my wits end.
Throughout all this, Mail on my ipodtouch o.k.
I appreciate help.

Is it sleeping or shutting down?
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there.

Mail does not retreive messages after upgrading to Mountain Lion

I just upgraded my work iMac (2009) to Mountain Lion last night and now it will not retreive any messages from my work email account (POP). It was working fine yesterday (and for the past 3+ years) while I was still on Lion, but despite searching for answers and trying multiple solutions for several hours, I still cannot get it to work. Among other things, I have deleted and then added the account back (multiple times); restarted the Mac (multiple times); and zapped the PRAM, but nothing has fixed it yet.
When I select "Get Mail" from that mailbox and watch the Activity Monitor, it connects to the server, says "Fetching new mail", then "Preparing to retreive new mail", but it then just disappears after about about a minute and makes the "no mail" beep. There are no error messages, but I can see in the bottom "Mail Activity" window that it says it's downloading 40+ messages but nothing shows up. The mail account still works on my iPhone and I can check the mail on my webmail server, so I don't think it has anything to do with the server especially since it worked fine yesterday.
Any insight would be much appreciated because it's driving me crazy!!

I forgot to mention (and add a new level of strangeness) that Mail is retreiving all of my messages from my personal (AT&T) account without issue.
And I just discovered an even bigger problem: all of my emails from my Sent and other folders from my work account are completely gone!
I may have no choice but to revert to my Lion system as of yesteday, before I installed ML.

After upgrading to Mountain Lion from Lion, Mail, Safari and note need about five minutes to start.

After upgrading to Mountain Lion from Lion, Mail, Safari and Note need about five minutes to start.
After starting, Mail answers are very very slow. The same for Note. Instead of, sending mails is only a bit slower than before upgrading.
In Safari, I choose Goggle as starting page in Preferences, but at every restart misses that starting page and the search strip says "Seek Google or instert an address".

Well, I found the solution here in another thread.
i just want to mention that the samw thing was happening also for the notes and the reminders apps!! (they quit unexpectedly!!).
So I found the solution here.
Thank you graphicsluc!!!

After upgrading to mountain lion e-mail no longer pushes to my i-Phone

after upgrading to mountain lion e-mail no longer pushes to my i-Phone I have to launch the mail app on phone to retrieve mail now

The OS on your Mac has nothing to do with behavior of email on your iPhone. The only thing I can imagine is that Mail on your Mac may be receiving messages and marking them as "read" before your iPhone has a chance to receive them. What kind of email account are you talking about here!

After upgrading to mountain lion, i find that my mail app does not have a "VIP" Tab. Was wondering if anyone else has this issue and what it is about?

after upgrading to mountain lion, i find that my mail app does not have a "VIP" Tab. Was wondering if anyone else has this issue and what it is about?

First, select sender(s) as VIPs. Then the VIP category will appear.
To select a sender as a VIP, open an email from that sender, then hover over their name and a star icon will appear to the left. Click the star, and that sender will be set as a VIP (and the category will appear in the pane on the left).

Mail sorting problem after upgrading to Mountain Lion?

I have a strange problem with Mail after upgrading to Mountain Lion.
Before upgrading, when I tried to search my Mail Inbox for e-mails from a specific sender, the esearch results would be indexed by the name of the sender. For example: when I entered 'John Smith' in the search box in Mail, it would display a list of email from 'John Smith'
Now after upgrading, the same query indexes the search results by the 'To' address i.e. my email address.For example: if my name is 'Steve Johnson', a search for 'John Smith' in the search box in Mail displays a list of email to 'Steve Johnson' and not from 'John Smith' which is how it used to display before.
My emails are sorted by Date always, and I am using the default Mail view [not classic view]
Can someone please help with a fix for this to help me get back to the original display I had while searching? Thanks in advance.

I'm having the same problem. It's incredibly annoying!!! Did you find an answer?

HT4798 username/password not working after upgrade to mountain lion

hello, on my imac after upgrading to mountain lion my computer password and/or username seems not to work anymore: when i want to install an update or search for updates on the app store the combination i used so far, does not work anymore. i tried to find out how to reset the computer password but without too much success, and i'm a bit confused, what can i do? thanks a lot

You went wrong at the very beginning by not erasing the hard drive of a used computer before starting to use it yourself. I suggest you do that now.
Back up all data to at least two different storage devices.
Boot into Recovery (command-R at startup), launch Disk Utility, and erase the startup volume. This operation will destroy all data on the volume, so you had be better be sure of your backups. Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups. For a walkthrough, see here:
Using Setup Assistant
Don't transfer the Guest account, if it was enabled on the old system.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

Why has my Safari and MAIL slowed after upgrading to Mountain Lion on my MacBookPro ?

Why has my Safari and MAIL slowed after upgrading to Mountain Lion ? I have mid-2009 MBPro and have very fast Internet access router.

I have noticed the same thing on my MAC. Mail has become very "clunky"- Before Mountain Lion, whenever I clicked on a msg or a function (delete), it would respond immediately. With Mountain Lion there is an unacceptable hesitation. What is going on with this latest update?

ITunes doesn't sync iCal with iPhone after upgraded to Mountain Lion

iTunes doesn't sync iCal with iPhone after upgraded to Mountain Lion. I even tried to use Replace Information On This iPhone and it doesn't work. Any idea guys?

I'm having the same problem. It's as if my iPhone and MacBook Pro now have two separate calendars.
Basically, I have a MacBook Pro (Mountain Lion, 13", late 2011) that I sync via USB with an iPhone 4S (iOS 5.1.1). Before upgrading to Mountain Lion, all of my iCal events would sync flawlessly. But none of the events I've created in iCal (Calendars) since upgrading have synced to the iPhone. Likewise, no new events that I create on the iPhone Calendar will sync to iCal. Also, changes to an existing event (even one created before upgrading to Mountain Lion) don't get synced either.
Everything else seems to be syncing just fine though (music, apps, contacts, etc).

Mail problems, slow browsing and Facebook problems after upgrading to Mountain Lion

Hi !
I have a 27” iMac from late 2009 which started acting really strange after upgrading to Mountain Lion.
Before that everything works fine but now Mail does not work, will not send replies or add attachments and browsing has become so slow that it usually times out. Another strange problem is Facebook messages which does not work at all (cannot read nor send(.
I have Lenovo laptop connected to the same network so I can benchmark and browsing works just fine on that aswell as FB messages.
Anybody got a solution to this other than using the iMac for offline use only ?

Hi !
I booted both the modem and router but it did not help. Then I tried using the iMac on wireless and now it works so must be something in my D-Link router.
Thanks for pointing me to the right direction !

Hi after upgrading to mountain lion my mail rules keep disappearing this has only happened since i installed mountain lion.

Hi after upgrading to mountain lion my mail rules keep disappearing??? this has only happened since i installed mountain lion.

I had Mountain Lion on two Macs. Mail rules were set up on a third Mac running Lion. I migrated everything on the Lion Mac across to a new iMac running Mountain Lion so now I have Mail rules on a Mountain Lion Mac. At least I should have. Several times a day the rules disappear. I assume this is iCloud synching messing up. I keep re-entring the rules but they vanish again and I'm getting tired of the game.
Large chunk of my Safari bookmarks bar also disappear at random intervals. It seems that iCloud can handle two Mountain Lion Macs on the same Apple ID, but can't cope with three.

HT1338 After upgrading to Mountain Lion iphoto doesn't work

Can't open my iphoto after upgrading to Mountain lion. Goes up to step 2 at 54% and crashes. Please help!

You can't run Windows on a Mac unless you use BootCamp or a third-party utility such as Parallels Desktop.
Perhaps you mean Microsoft Word (which is part of the MSOffice suite).
Only MSOffice 2008 and later will run in Mountain Lion.
However there are very good free alternatives, such as LibreOffice.

Dashboard widget with streaming video breaks after upgrade to Mountain Lion

Hi. I recently upgraded from Snow Leopard to Mountain Lion. Under SL, I had an OS X widget that was a web clipping of a streaming mpeg image being produced by a Linksys/Cisco WVC54GCA web camera. When I brought up the dashboard, the OS would start streaming the data from the mpeg filename, which looks like "hostname.com/img/video.mjpeg".
After upgrading to Mountain Lion, I noted that the widget never fully loads, indefinitely displaying a "Loading Clip..." mesasge. After deleting and re-adding, I can still get as far as adding the web clipping to the dashboard at the right dimensions, but there's no content.
Unfortunately the camera unit doesn't provide for the display of HTTP access logs, so I can't see if there's an issue there, but my understanding is that if I can display the image in a Safari browser, it should work just fine in Dashboard too. (I did make sure that, where needed, the username/password for accessing the video are included in the URL.)
I did sniff the network traffic between my system and the camera host, and show that video traffic starts flowing between the two as soon as the widget is brought up. So, it's almost like the widget doesn't know when to stop "loading" and start "displaying," perhaps because the HTTP request is never truly "done."
Can anyone speculate if something may have changed in Mountain Lion affecting the ability of web clipping widgets to display streaming video?
Thanks,
Chris

Hi James
I have exactly the same problem with the same "Loading clip" then blank. I have been trying a lot of stuff to get this working, but haven't had the chance of sniffing the network traffic as you have done. By reading what you said about the traffic seems to be flowing without the picure being displayed makes me even more puzzled by this. I never had a streaming video while I were using Snow Leopard, but I had a still-image, as I also do now in Mountain Lion. I recently began to research for a way to display the video.cgi MIME image that my camera produces, and I've also concluded that this should be an easy task for the dashboard web clip function; the video does display in safari after all.
I suspect that our cameras uses the same built in webserver solution written by a "Steven Wu". Cheap webcameras frequently uses his script with MJPEG (stream of JPEG pictures) to avoid the expensive licenses of using other video codecs.
I read this a bit down at this site: http://channel9.msdn.com/coding4fun/articles/Everyone-Loves-Babies-Webcams-and-M otion-Detection
Have you come any closer in your research?
I have started to think that maybe I have to write a dashboard widget on my own to accomplish this.
