the issue i'm having is this has cached my login credentials b/c i didn't uncheck Remember this password... How do i clear? I'm doing testing for work & need to enter different credentials to get different results

Have you applied all the Apple patches via the menu ==> Apple logo > Software update?
There was an issue with wifi in the unpatched ML, but this has long been fixed.
Another suggestion is to apply a fixed ip address to you Macbook.
I presume you have rebooted the router?
If you hold the "Option" key and click on the wifi symbol on the menu bar you get to see more stats about your wifi connection. Check that it is running in 802.11n mode.

Why didn't Apple make it clear that if you upgrade to Mountain Lion on an older Mac, and want mirroring to work you were out of luck ?

I read the requirements to install Mountain Lion. My system quilified, that is unless you wanted all the features to work. Mirroring is not a "Key" feature that will work on older iMAC machines. What a letdown for features I wanted to really work.

I feel really let down that my $2000+ i7 8gig MacBook Pro (mid 2010) can't mirror it's screen with AirPlay, but. $600 Mac mini (2011) can.
Really? Is wireless video *that* hard? I've been a long time Apple supporter, (1991) way before iAnything, and in those dark years up until now, I always made the point that Apple hardware had longevity. Of course my MacBook is still functional, built like a tank, and I'll get years out of it, but Apple dropping support for a top level machine so soon is unsettling.
I really, really wanted AirPlay, and bought Mountain Lion right away. It wasn't until later, while waiting for the download I noticed my beloved MacBook wasn't supported. Apple really should change their advertisements to make clear it's really only for brand new machines.

Dropped Wired Ethernet on Mountain Lion

After upgrade to Mountain Lion
The Ethernet connection will no longer create a network connection to Broadband / Router. Boot into Windows from Boot Camp and all is fine.
Wifi works fine in OSX. In Network Preferences you see Ethernet toggle between RED - No cable connection to Yellow cannot get IP
Again under Window on Bootcamp all is OK

hmmm interesting...
unplug your computer. Turn it on. Let it drain completly down where the computer actually shuts off itself. Then recharge your computer fully and see the difference.

Clear procedure to move back to Mountain Lion from Maverick

Hi,
I had a question related to the purchasing of Moutain Lion on apple store.
Having some trouble with many of my device (for egs 3G key) which are not upgraded (software) to face Maverick, I bought online a version of Moutain Lion to downgrade to this OS for the time needed to see the drivers being uprgraded
But it seems the procedure is quite complex when you have to face a downgrade of the OS.
Is there any clear procedure available to follow to realize such change (answers on forums are numerous but often complex)
Thanks in advance for any response

Here is an excellent and clear user guide:

ITunes movie playback, audio and video not in sync after upgrade to Mountain Lion

After upgrading to Mountain Lion I have problems with iTunes movie playback, and the audio/video at times stalls/delays, or skips a few seconds, or even gets out of sync. I feared this problem was isolated to my machine until I saw an article online: http://reviews.cnet.com/8301-13727_7-57489874-263/sound-stuttering-after-mountai n-lion-installation/. I have 2011 iMac 27" with 16G RAM and am running the latest iTunes and Mac OS X software, and shutting down extra programs doesn't help. Please let me know of any solution.

I also have this problem, and some videos will no longer play in iTunes.
I get a message that this video is not compatible with this version of iTunes. I have to open the video in Quicktime to watch it.
Unacceptable! This hardware and software is too expensive to have these performance issues.

Why is the fan in my iMac running so much after Mountain Lion update?

For some reason, I seem to notice the fan on my 4 year old iMac running constantly, even with very few processes running (only Mail and Safari) after the upgrade to Mountain Lion. Anyone else have this problem? Anyone have a solution?

Sorry, guys (or girls), but NONE of this worked. I shut down, pulled the plug, restarted, Zapped the VRAM, restarted, several times...I mean, at least 4. There were NO major processes going on according the Activity Monitor. And with only Mail open, the fan began to run at high RPM (HD fan at 1486, CPU fan at 3896, CPU temp 41, CPU heatsink temp 41, GPU Diode temp 95, GPU Heatsink temp 90) almost immediately...and it has yet to go off. I suspect it won't do so until I leave it alone and it "sleeps" for a while. I have read that other people have this problem too, and it clearly is related to something in Mountain Lion, since that was the triggering event. I believe Apple must be advised that this is a software glitch, and they should work on getting a patch out to us.
Any more advice? I'd love to hear it.

Start up DVD not recognised by mountain lion

My start up DVD not recognised by mountain lion-how do I get around this for restoring from time machine?

It's not very clear: Are you trying to reinstall Mountain Lion from a DVD copy you made of it, for some reason? And if so, why would that help you restore from Time Machine? Please give more information. Properly, to either reinstall Mountain Lion, or to Restore it from Time Machine, you need to reboot while holding down the Command - R keys as mcsound above recommended, to boot into the Mountain Lion Recovery Partition to do either.

How do you update to mountain lion free if you buy a mac today?

I don't know if it was announced today or not

On the Apple Website this appears:
Seems quite clear to me, the upgrade to Mountain Lion on a Mac bought on or after today will be free.

Connecting to an 802.1X wired network

Does the AirPort support connecting to a 802.1X wired network?

Windows 7 802.1x (Wired) Authentication Failure when logging into Lync 2010

Hi
My company has implemented 802.1x Wired authentication, we use GPO to specify a
Wired Profile that uses a COMPUTER certificate.
We are finding that when a Windows 7 laptop comes out of sleep or hibernation, the laptop fails 802.1x authentication and does not connect to the network.
This issue only occurs intermittently, but have been proven to occur only when Lync 2010 is open. If we close Lync 2010 the issue does not occur. Lync 2010 installs a self signed USER certificate for authentication.
I am aware that there are some issues around Windows 7 not selecting the correct certificate when responding to authentication requests (KB2710995,
KB2769121) but these always specify that the issue occurs when 802.1x authentication uses USER certificates, not a mix of USER and COMPUTER. We have installed these hotfixes and the
issue still occurs.

Hi,
From the description, you suspect the DHCP request cause this issue. Would you please send us the packets? Since it seems that you have looked into the traffic and found some clues.
Meanwhile, I found the following hotfix which may related to this issue.
No response to 802.1X authentication requests after authentication fails on a computer that is running Windows 7 or Windows Server 2008 R2 http://support.microsoft.com/kb/980295/en-us
Next Action Plan:
1.Clean Boot
a. Click Start, click Run, type "msconfig" (without the quotation marks) in the Open box, and then click OK.
b. In the Startup tab, click the "Disable All" button.
c. In the Services tab, check the "Hide All Microsoft Services" checkbox, and then click the "Disable All" button.
======================================================
Clean Boot + binary search
In a Clean Boot, all the 3rd party services and startup programs are disabled. If the server can start normally in Clean Boot, we can be sure that the issue was caused by some 3rd party service or application. And then we can do a "binary search".
You can enable half of all the services in Services tab, and then restart the server to check the result. If the issue reoccurs, it means the culprit is in this list; if not, the culprit is in the other half. And then, we can continue the binary search, until
we find out the root cause. Please let me know if this action plan is OK for you.
2.Collect etl trace on the problematic client.
netsh trace start capture=yes overwrite=yes tracefile=c:\net.etl filemode=circular
****Try to reproduce this issue****
netsh trace stop
Please send the net.etl to us for underlying analysis.
For any concerns, please let us know.

IAS and CTA 802.1x wired client?

Hi,
We have IAS working with 802.1X authentication. All is good except when we enable dynamic VLAN assignment we come across the Winlogon issue as per MS KB article 935638.
We do however have available the CTA 802.1X wired client. From what I have read though it requires ACS due to use of EAP-FAST. Is this correct or is there some way I can get CTA 802.1X wired client working with MS IAS RADIUS?
Thank you

You will have to use ACS for authenticating using EAP-FAST for CTA 802.1x wired clients. It is not possible to get CTA 802.1X wired client working with MS IAS RADIUS.

802.1x wired authentication via PEAP, MD5

Hi everyone,
Thank you for taking the time for reading this, I am implementing a security solution and wanted to take th benefit of implementing 802.1x over wire. I have been searching a bit but no much info from start to finish on how to implementing this solution,
i would really appreciate if someone could point me some where to find detailed instruction on how to do this, as so far i have been configuring in multiple way bit no result out of it. Still a orange port color on my switch, that means the first
hop of security work but the next no.
Thank you in advance to read this.

Hi,
According to your description, my understanding is that you want to deploy 802.1x wired authentication via PEAP, MD5 and need instructions about this.

How to clear calendar cache on Mountain Lion

At least, I think that's the problem.
I have multiple Apple devices (iPhone 4s, iPhone 5, Macbook Pro running 10.8.3, and Macbook Air running 10.7.x (it's not in front of me at the moment)), and we're talking about an Exchange calendar.
I deleted all future occurances of a recurring appointment on the Air. It removed from the calendar on the Air, and synched to all of the iPhones. However, it did not get removed from the Pro running Mountain Lion. If I then try and delete the appointment from the offending machine where it still exists, it gives the spinning pinwheel for about 20 minutes, but ultimately removes it ... until I quit Calendar, and open it back up, at which point the meeting has returned (even though it's still not on any of the other devices, and if I log in via Outlook on the web, appears not to be on the Exchange server either).
The above sounds like a cacheing issue to me, so I tried the following:
Deleted the Exchange account from Mail, Calendar, and AddressBook.
Removed the following files and folders:
~/Library/Caches/com.apple.CalendarAgent
~/Library/Caches/com.apple.iCal
~/Library/Preferences/com.apple.CalendarAgent.plist
~/Library/Preferences/com.apple.iCal.plist
~/Library/Preferences/widget-com.apple.widget.calendar.plist
Then I rebooted, opened Mail, and added the Exchange account (including address book and calendar) ... and the deleted appointment immediately returns! (certainly much faster than it could be syncing with an Exchange server, so it must be getting it somewhere local).
The only sign of anything going amok is in the Console log:
CalendarAgent: Unexpected EOF, returning last token as fallback
Does anyone have any suggestions on either how to really clear the Calendar cache on Mountain Lion; or other guesses as to what the problem might be?
Thanks!
Chris

You must be right:
CorelDraw was originally developed for Microsoft Windows 3 and currently runs on Windows XP, Windows Vista, and Windows 7.[26] The current version, X6, was released on 20 March 2012.
Versions for Mac OS and Mac OS X were at one time available, but due to poor sales these were discontinued. The last port for Linux was version 9 (released in 2000, it did not run natively; instead, it used a modified version of Wine to run) and the last version for OS X was version 11 (released in 2001).

Who is really doing 802.1x wired

I am creating a lab environment to test 802.1x prior to implementing it into production.
I wanted to know what is the pros and cons of this security feature at layer 2?
How does it really work behind the scenes?
The reason why i want to implement this feature/function is becuase I'm just one of two network administrators who manage well over 800 networking device (totally cisco shop) and 62 remote sites, and we struggle with the moves, adds, and changes, port vlan assignment (management), users moving there workstations, users moving there voip phones, etc. If anyone can speak on implementing 802.1x wired in a medium to large large network i will be happy to hear about the real life pros and cons

We implemented 802.1x in my previous company (similar size as yours)
You are right it can brings lot of problems.
Before we deployed management solution Cisco LMS 3.0... It really helped us with configuration, config backup, network overview, discrepancy reports, user tracking, troubleshooting (get rid of fake hubs etc..) ... It cleaned our network and saved lot of time .. I suggest to have good management solution before you move to 802.1x
We also separated devices what are not able to authenticate via 802.1x (printers, faxes) to separate VLAN
Than we started in one segment (vlan) which was most stable (no changes, no moves)...
It worked fine.. Than we smoothly moved to other vlans step by step..
The true is that it took lot of time (one of my colleagues was working only on this project for some time).. But we managed it and it works fine.. It would also asked your cisco vendor for consultancy and help
Hope that helps

How do I clear the "recent" user account pictures in Mountain Lion?

How do I clear the "recent" user account pictures in Mountain Lion? A friend posted a stupid photo as one of the pictures as a joke and I cant figure out how to remove it from the recent pictures.
Thanks

To completely remove the files, from the desktop click Go>Go to Folder and type
~/Library/Containers/com.apple.ImageKit.RecentPictureService/Data/Library/Images /Recent Pictures/
Then move the files you don't want to trash.
Make sure to empty trash and restart before viewing your recents again, or they will reappear.
