Mountain lion cannot handle multiple monitors. Why?

Runnig Mountain Lion 10.8.1 on a MacPro Early 2009.
Mountain lion has screwed my multiple monitor life up! With Lion I was able to have 5 multiple monitors rotated 90 degrees running without a hitch. I know... I am a visual learner . I have 3 Nvidia Geoforce GT 120 512 MB graphics cards. All bought from apple. Why can't mountain lion handle multiple monitors in any rotation? Is there going to be a fix soon? like 10.8.2? Does anyone know if apple is working with Nvidia to correct this? I am back to just 1 90 degree rotated monitor.This hurts.

10.8.3 DOES NOT WORK for me.
this did NOT solve my problem... I responded too soon.
Yes I am able to have 6 monitors in portrait mode with 3 Nvidia Geoforce GT 120 512MB graphics cards but as of yesterday, my whole system shuts down and reboots. This happened 3 times in the span of about an hour.
I removed all but 2 monitors running on only 1 Nvidia Geoforce GT 120 512MB graphic card and the system crashes stopped.
So I am back to either waiting again for some resolution from apple or looking into buying newer graphics cards.
Oh well, it was fun while it lasted... a whole day.
Again, I can't get no satisfaction...

FCPX + Lion + Cannot handle AAC or Apple Lossless audio in H.264! (Clicks and Pops)

This is a problem I've been having since I upgraded to Lion, and I've posted this response in other forums, but wanted to start a fresh one with a video I created of my findings. In a nutshell: FCPX in Lion cannot handle AAC audio in H.264 files since it will create audible clicks and pops when it subsequently renders the footage. This ***** because the iPhone 4 for example records as H.264 and AAC for the audio. Below are my findings:
So I think I figured it out! (I'm pretty sure FCPX + Lion has issues with compressed audio formats, ESPECIALLY AAC and Apple Lossless!) There's a video of my findings below:
1. I tried doing exactly the same thing I was trying to do on my machine on a co-worker's Snow Leopard MBP, and it worked out fine (it was just importing an iPhone 4 .mov and exporting it in FCPX). The output file was pretty much the same as what came in.
2. I found out that only movies from my iPhone 4 were coming out all crazy in the audio, yet my Canon T2i files were fine. Both are H.264, yet the Canon T2i records audio as Linear PCM, while the iPhone 4 records audio as AAC.
3. So I got an idea to use screen flow to record a youtube video and record the computer's audio. Then I decided to export with different formats, both as HD NTSC standards and as web standards with H.264.
4. I found out that both NTSC and H.264 standards were perfectly fine, SO LONG AS THE AUDIO WAS LINEAR PCM (or uncompressed!).
5. I then exported the same clip (both times as H.264) and ONLY changed how the audio was rendered (either Linear PCM/Uncompressed or AAC) and VOILA, I got click and pop artifacts ONLY in the AAC version. The ones that were output as uncompressed audio were totally fine!
CONCLUSION:
Final Cut Pro X on OS X Lion has issues with compressed audio, MAINLY AAC and Apple Lossless! Anything that is Linear PCM/Uncompressed should be fine! For example, MPEG 4 AAC Enhanced Low Delay at 320K came out 95% OK, one or two clicks.
So if any of us are working with material where the audio came to us already as AAC (like an iPhone 4), then we have to rip the audio out somehow first (like through VLC for example) and import it separately as an uncompressed file.
Here's a youtube video showing exactly what I'm talking about:

Anybody else have any thoughts on this before Apple comes out with a fix?

I was having the same problem and spent several hours on the phone with apple working with one of their 3rd level support guys. Their is deffinatley a issue with Lion and FCPX. I was told they would escalate to a FCPX engineer and they would get back to me in two days. In the mean time I went to my local apple store and was able to recreate the issue on every machine I tried. Apple did call back and confirm that there is an issue with the way FCPX and Lion handle the import and export of AAC files. They said there would hopefully be fixed in a future update.
The best work around I found is to take your AAC file and convert it to a WAV. I used compressor to do this and it seems to have solved the problem.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

1)Creating the core dump directory:
   server$ sudo mkdir /PanicDumps
   Password:********
   server$ sudo chown root:wheel /PanicDumps
   server$ sudo chmod 1777 /PanicDumps
2)Activating the core dump server
   server$ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.kdumpd.plist
   Password:********
3)Verifying the core dump server is active
   server$ sudo launchctl list | grep kdump
   Password:********
    - 0     com.apple.kdumpd
2、Configuring a Client
client$ sudo nvram boot-args="debug=0xd44 _panicd_ip=10.***.***.***" （10.***.***.***

Before I updated today to Lion OS, my multiple monitors worked fine. Now my macbook will not detect them. Is there a solution for this?

I've been running multiple monitors for over a year on my Macbook. Updated today to Lion OSx and well Steve, it didn't just work. My macbook will not detect my three external monitors, and after scouring the last hour on Google of how to remedy this and trying the basic suggestions of restarting, unplugging, replugging, to no avail. Anyone else have a similar problem since they've upgraded to Lion OSx?

1-Time machine seems to be coming up often in the discussions.If my backup is on my external hard drive, why would space be taken up on my macbook hard drive?
Read the first extract for the definition of backup snapshots and how they are handled by the OS.
2-Shoud I delete older backups? If for example, all I need from Time Machine is the latest backup done today, can I get rid of the 2+ yeras of backups, or do they not take up that much space?
No. Time Machine should be on a separate HDD and will take care of deleting backups when necessary on that drive.
3-Back to the issue, considering I don't have access to a an apple store for the next few months, what is my best plan of action?
I would consider installing a larger internal HDD. Capacities to 1 TB are now available.
4-I am considering buying a new macbook 15inch, and get more space, however, I'm scared that the same problem will happen again. Is this common on all macs? Will using Time Machine to "Restore" my backups bring along the issues as well?
All Macs using Time Machine will experience the same conditions. The problem is that many users do not under stand what 'Other' is and that leads to confusion. There are many essential OS files in that category that should not be touched as well as some user files. The issue is not to reduce 'Other' as such, but reduce the total amount of data on the HDD if space is becoming a premium.

I just purchased OS X Mountain Lion Upgrade. When I went to install it is says "Os X Mountain Lion cannot be installed on Macintosh HD" please help!

Just purchsed upgrade OSX Mountain Lion. Went to install and it says "OSX cannot be installed on Macintosh HD" Why?

Hi,
If you bought the iMac in 2010 it should be supported indeed, however be aware that the information refers to the manufaction date which might be different than the purchase date.
Please verify the following information:
Click the Apple icon.
Click About This Mac.
Click More Info.
What is the listed Model Identifier?
You may identify the exact model by comparing it with the Model Identifier below:

Now go back to your Desktop, click the Go menu and select Utilities.
Open the Disk Utilitiy.
Select Macintosh HD from the left pane.
You may find the Available space listed in here.
As well, what it the listed Format within the same screen?

Mac Reminder (Mountain Lion) cannot sync with Exchange Server 2010

Hi All,
My boss is using iMac reminder (Mountain Lion), iPhone and iPad sync with his Exchange Server account, He cannot sync Mac reminder with Exchange Server last week. However, there are no sync problem of iPhone, iPad and the other iMac.
My boss mail to me 'Just noticed that my iMac reminder is not in sync with the server. IOS device is in sync though. Tried unchecking calendar+reminder on account setup and rechecking but still no good. Any ideas?'
Could anyone help me?
Thanks,

Started experiencing this same issue with new Macs on Moutain Lion connecting to MicroSoft Exchange Server.
ERROR Says:
Calendar can't save the event "event name here" to the Exchange server.
The account "describes calendar name" currently can't be modified. to discard your changes and continue using the version of your calendars that's on the server. click Revert to Server.
Then gives the buttons "Revert to Server" "Try Again" or "Ignore"
!!! Somehow it seems like this is a known issue, otherwise WHY would Apple have given us those 3 buttons to click on?
Needless to say this is causing productivity problems as it disrupts the very busy schedule of many users. Apple needs to provide some workaround for this.

With Mountain Lion, airplay no longer works, why not?

The only thing that has changed is that I went from Snow Leopard to Mountain Lion.
Have mid-2010 iMac, 3 Airport Express', 3 powered speakers. Was able to send music to three rooms. Firewall was on.
After upgrading to Mountain Lion I noticed the firewall was off. I turned it back on.
I tried sending music via the Airport Express'.
Got a message that my firewall settings were preventing Airplay and that I should turn the firewall off.
That seems likde a bad idea.
Any suggestions?
Thanks.

Mountain Lion - cannot copy and paste in finder

Hey,
     I've only just noticed this today and I've done a search but can't find anything so far to help me. I upgraded from lion to mountain lion the day after it was released, not fresh install, upgrade. Basically... I cannot copy files using either cmd+c / cmd+v or using the finder edit->copy / edit-> paste menu. They aren't greyed out. Everytime I try I get the error "The operation can't be completed because you don't have permission to access some of the items.".
This will happen even with a newly created folder. I can delete files. I can create files. I can drag files in finder without issue but I cannot copy and paste. I'm guessing there are permission issues going on but I don't know where to start.
Repairing permissions didn't help (I kinda didn't think it would given it only works on system files but thought it worth a go).
This is an example of the file permissions assigned to a screen grab on my desktop:
-rw-r--r--@ 1 jackwestbrook staff
64257 1 May 19:48 Screen Shot 2012-05-01 at 19.48.27.png
Even if I blow it wide open with chmod 777 I still can't copy it...
-rwxrwxrwx@ 1 jackwestbrook staff
64257 1 May 19:48 Screen Shot 2012-05-01 at 19.48.27.png
These are the permissions assigned to my desktop:
drwxr--r--+ 19 jackwestbrook staff
646 19 Aug 18:24 Desktop
Can anyone offer me some advice on where to start with sorting out this issue?
Cheers,
Jack

Hey, I was really loathed to try reinstalling the OS and something told me that I'd I can drag and drop but not copy and paste there had to be something interfering with the clipboard.
I disabled Alfred and its clipboard history feature (http://www.alfredapp.com/) and rebooted. Amazingly this fixed my issue. I'm going to email the author in the morning to give them a heads up about this.
Thanks to both of you for taking the time to offer me advice.
John Guo - nice tip, wasn't aware of that!

MBP Mountain Lion Cannot read or recognized Micro SD Card and SDHD card

I recently did an update on my MBP and imac (both are mountain lion: OS X 10.8.2 ). Now both cannot read or recognize my Micro SD card (inserted using adapter**) or my SDHD card when inserted in SD slot. I could not see the card in Disk utility either. I started having the problem today after I did the update earlier this week, but last week it was working fine. Can someone please help me? I do not know what else to do. Your kindness is highly appreciated.Thank you.

Mountain Lion - Cannot download additional components???

My MacPRO (2008) was running like clock work, but recently a gremlin has appeared. I have been on this forum before and so far all information has been really useful. The mac would start up and shutdown in one motion. I didn't even have enough time to bypass or boot from an alternate drive so it was off to the mac centre to find the cause. Weirdly enough they found nothing wrong and it was good to go. I decided this might be an opportunity to rebuild from scratch and so my 4 drives I zeroed the data and tried to reload Mac OSX 10.8. It starts all well and good before stopping after a few minutes and flagging a problem "cannot download additional components". What is causing this and how do i get around the problem. I would take it back to service centre but have lost confidence in there competency since everytime I take it there it comes out worse than it went in.

Did you get to the point where you have downloaded the entire package from AppStore?
Save the ESD package and prepare an install disk and do a clean install.
Usually - there was one person recently here but cannot find buried in a thread, they had 10.8.2 and the installer is 10.8.3.
What are you running now?
As for the original problem, for which no problem was found... are you using an SSD to boot the system?
How to do clean install of Mountain is same as was for Lion, with how to clone a system.
Make sure you have 8GB flash drive, or even a small (16-32GB) partition (yes, you can setup an installer to run from hard disk drives to do a clean install to another drive or partition).

Need help to find photo's on my backup drive,since installing Mountain Lion cannot find where they are stored.The backups after ML install are greyed out except in Applications, MyFiles and Devices really welcome a hand with this please.

I need help to find my photo's please (2500) on my backup drive.Lost them after doing a clean install of Mountan Lion I have tried to find them but had no luck. I use Time Machine with a 1TB Western Digital usb drive. Thanking anyone in anticipation of a solution.

-Reece,
We only have 1 single domain, 1 domain forest, no subdomains, only alias. I had replied to the other post as well. But I am happy to paste it here in case anyone want to read it.
So, after a few months of testing, capture and sending logs back and forth to Apple Engineers, we found out there is a setting in AD, under User Account that prevent us to log into AD from Mountain Lion. If you would go to your AD server, open up a user account properties, then go to Account tab, the "Do not require Kerberos preauthentication" option is checked. As soon as I uncheck that option, immediately I was able to log into AD on the Mac client. Apple engineers copied all my AD settings and setup a test environment on their end and match exact mine AD environment. They was able to reproduce this issue.
The bad part about this is... our environment required the "Do not require Kerberos preauthentication" is checked in AD, in order for our users to login into some of our Unix and Linux services. Which mean that it is impossible for us to remove that check mark because most, if not all of them some way or another require to login into applications that run on Unix and Linux. Apple is working to see if they can come up with a fix. Apparently, no one has report this issue except us. I believe most of you out there don't have that check mark checked in your environment... Anyone out there have any suggestion to by pass or have a work around for this?

MacPro Early 2008 Mountain Lion can't remember monitor setting

My Mac Pro with two cinema displays and Mountain Lion starts with a "default" display setting. That means, display one and display two change after restarting the system. The OS is unable to save my settings!?

I'm largely in the same boat. I'm running 10.6 and I bought both my computers on the cusp of the capability range apple listed. I had no way of telling if they fell in the right category. I looked for something that listed serial number ranges or some kind of app that would tell me if they would be compatible but found nothing that was definitive. I even called Apple and they said it sounds like my computers will be fine. Saying things like "Mid/Late 2007 or newer" is hardly precise. Needless to say I bought my Macbook Pro in mid 2007 and my Mac Pro in early 2008. Both have turned out to not support 10.8. I have no problem with that but would like to at least upgrade to 10.7. 10.6 is still available via phone sales but not 10.7. Very fustrating.
