Screen Brightness control disappeared after upgrading to Mountain Lion

Hello all.
I've just upgraded to Lion, and now I can't adjust the brightness of my screen anymore!
Anyone else has this problem?

I was having the same problem after I completely tore down my Macbook Pro mid-2010 in order to replace the keyboard. (Phew!) After re-asssembling, everything was working again except for the screen brightness buttons (F1,F2). I figured it was a bad keyboard, but after zapping the p-ram, the brightness buttons now work as they should. Thanks for the tip!

Help! My events disappeared after upgrading to Mountain Lion!

I just upgraded to Mountain Lion 10.8.2 (and signed up for the accompanying iCloud, fyi), but when I opened iCal/Calendar my events were gone. For some reason, my repeating all-day events are still there, but everything else - non-repeating all-day & any time-specific events - is gone. I know that I should have backed up before upgrading, but I didn't. Is there anything I can do to get my events back??? I'm in a slight panic.

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.

After upgrading to Mountain Lion it's not possible to play videos in Fullscreen Mode

Hello everyone,
after upgrading to Mountain Lion on my iMac (27 inch, Mid 2011) I got the problem, that every video or movie in full-screen mode jiggles after a while. I'm using my Mac as a TV with Elgato EyeTV - and usualy I use it in full-screen mode.
A complete new installation from scratch didn't solve my problem.
If the problem occurs, the processor idles ans the hard-disk activity is low.
Is there anybody out there, who can help me?
Regards,
Stephan

If the issue only occurs when watching TV (using Elgato) then it's an issue on their side. Try a browser window and if can view the browser in full screen mode then that proves the point. You can also create another user account, log into that account and see if the issue is still there. If it disappears then you have an issue in your normal user account that needs to be tracked down. If the issue persists then your issue is global.

After upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer or even off my iTunes library

after upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer, love film or even directly off my iTunes library. in each case, all i get is a black screen and no error message.

Hi, i had the same problem and tried this,
Somehow iTunes is tied to Safari. Try this:
Someone mentioned to clear all website data and history in safari, stupid but it was either this or the below that fixed it
or this,
Disable Wi-Fi Networking Services
Many users have reported that they’ve solved their issues by disabling Wi-Fi Networking under Settings > Privacy > Location Services > System Services. This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.
Please let me know if it works.

On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion. They DO work on a lenovo machine but not my imac

On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion.
They DO work on a lenovo machine but not my iMac. reset Pram - no luck. took speakers from wife's desktop, they
do not work when jack plugged into my iMac - Sys Prefs "SOUND" only lists "internal speakers/ built in" as available options.
I used my altec lansing speakers on 3 macs including this one for 5-6 years.....now with Mountian Lion I can only get internal speakers???
Ideas? Any/All help would be greatly appreciated - been going nuts with this for 2 days now.

Hi,
When you start Messages fro the first time you are asked for an Apple ID
When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
The App should have also picked on on those iChat Accounst you had before.
These should be Enabled if they were when you last used iChat.
Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
This will give you separate iChat type Buddy lists.
You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
There is no Buddy list for iMessages side
No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
Obviously an Apple ID can be an email or look like one.
In some cases they are also valid AIM Screen Names as well.
In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.

TS1277 "iPhoto was unable to connect to Photo Stream" error after upgrading to mountain lion

Has anyone gotten this error after upgrading to mountain lion on a computer that already had a user setup on it?
My iphoto was working with photostream and now it will not connect at all.
I ran fix disk permissions and once it showed up in iphoto, photostream was loading and then it disappeared again.
help!

FWIW I fixed mine when I realised I'd probably downloaded iPhoto using an AppleID from the App Store but logged into iCloud with a different AppleID. I deleted iPhoto and it's related files (but not the iPhoto Library) using CleanApp, entered the App Store with my usual AppleID and downloaded iPhoto again. Once the App Store, the downloaded iPhoto and iCloud logins were the same iPhoto Stream worked again.

Imac keeps crashing in time machine backup after upgrade to mountain lion

2008 imac kept crashing (shutdown and restart) during first backup after upgraded to mountain lion. The backup size was about 10GB but time machine crashed after a while (at most 2GB) and never completed backup. So, I don't have any backup since right before I upgraded from Lion. Any suggestion?

Something strange happened. I was able to get time machine to work by going out to the login screen (the account kept logged in) and let it run the backup with the screen off (screen auto off after a few min). I tried it on two different external drives and that did the trick on both. Since the initial Mountain Lion backup was huge (155 GB), I was quite surprise that it worked at all. I assume your MBP was a Lion to ML. I also just did a 2012 MBP upgrade but that one was smoother. I did not recall having crashing issue. One thing I did find during this was that my WD passport USB drive was corrupted. Not sure it was the cause or not. I had to erase and reformat to get it back to work. Maybe do a verify disk to confirm. Good luck.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac. Anybody having similar probelms?
I am thinking about doing a clean install of Mountain Lion. Would I be able to restore my applications and data from Time Machine after the re-install?

My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem. After it sleeps, I go to use something... and the beachball of death occurs. This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
It could possibly be revolving around safari... as that is really the only thing that is running consistently. I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008. This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?

After upgrading to Mountain Lion, I repurchased Garageband and I can't get passed the complete installation. I don't seem to have the "com.apple.garageband.plist" file that has been a common solution. Any suggestions?

After upgrading to Mountain Lion, I repurchased Garageband and I can't get passed the complete installation. I've read through several posts that all reference the "com.apple.garageband.plist" solution. I don't seem to have the referenced .plist. Any solutions or suggestions?

Did you upgrade from SnowLeopard?
I can't get passed the complete installation
What exactly is happening? Is GarageBand trying to download over and over again?
all reference the "com.apple.garageband.plist" solution. I don't seem to have the referenced .plist.
The property list stores your preferences, but also the settings from the last run of the application. If that file is corrupted in some way, you might see third behaviour.
You must have this file, for it will be recreated automatically, if it is missing, or you have a permissions problem with your user library.
Perhaps you did look in he wrong place.
in MacOS 10.7. or later the User Library is hidden. To find the Preferences Files use the Finder's "Go" menu:
Quit GarageBand, if it is running.
Click onto you Desktop to bring the Finder forward.
In the Finder Menu press "Go" and hold down the "option/alt" key, until your user library appears in the drop-down menu
Select "Library" and in the Finder window that opens navigate to the "Prederences" folder; move com.apple.garageband.plist to the Desktop.
Log off and on again (don't skip that step!). Retry GarageBand and see if it GarageBand is now downloading the missing content properly.
If that does not fix the problem, post back and explain in more detail what the download problem is.
Why did you "repurchase" GarageBand? If you already owned GarageBand '11, it should be unnecessary.

After upgrading to Mountain Lion, I cannot open my File Maker Pro files. Can I use Numbers to open these files?

After upgrading to Mountain Lion, I cannot open my File Maker Pro files. Can I use Numbers to open these files?

Numbers is a spreadsheet program and FileMaker is a database program, so you probably can't use Numbers to open them unless you had first exported them from FileMaker in a spreadsheet-compatible format.
If you upgraded from 10.6 Snow Leopard or earlier and your old copy of FileMaker won't open anymore, it might be a PowerPC application that is not compatible with 10.7 and later. If that is the case, to work with your FileMaker files you should upgrade your copy of FileMaker to the latest version, which seems to be FileMaker 12.

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 10.8.2, I cannot print to my Samsung laser printer ML 2525w? How can I get this set up to print?

After upgrading to Mountain Lion 10.8.2 on my iMac, I cannot print to my Samsung B&W Laser printer ML 2525W either by USB or wireless. Any help on how to setup or reconfigure would be apprecaited.
I either print blank pages or prints one time then goes off line, or spits out a bunch of blank paper, etc. Have gone through all the standard fixes, reboot, reset , reload driver, etc.

From the link to the Thread you provided, I worked through the one message procedures that were listed.
For ease of reference, I have copied them and printed them below. This was an old thread but the guidance still works with no firmware upgrade required.
I would stress that you MUST delete any and all files relating to USB connection of the printer to the MAC, including all print drivers (from both Apple and Samsung either from CD or web downloads) and all print queues, etc. I was only able to get the printer to properly hand shake with my Mac by setting it up wirelessly after all old files were deleted with hard power off reboots on both the Mac and Printer.
I hope that someone from Apple will pass this note along to their programing department because there is some type of incompatibility in the new ML OS and the Samsung ML2525w print dirvers used for a cable (USB) type connection. Apple needs to be talking to Samsung to get the USB issue resolved. I am going to post this same message on the Samsung site to see if someone from there will contact Apple to work together on a final solution for USB connectivity.
Here is the steps I followed to get my ML2525w to work in the wireless mode. Again, I cannot stress the need to clean out all the old files (drivers, print queues, etc. - everything) before setting up wirelessly.
As a note, I ran this printer with Lion for almost 2 years and it always worked fine (both wireless and USB). From other comments on the thread, users were good with this printer using Lep. and Snow Lep also. - - no issues from either a USB connection or wireless until Mountain Lion.
Before the fix, I was experiencing many of the same issues as described on user chat threads, printer going offline after a print job. 1st page sometimes printing but all the rest of the pages were garbage. No printing at all. Printer just running a bunch of blank pages out. etc.
I run an iMAC 27" desktop with the ML OS upgrade just installed from Lion.
"I've just installed one of these printers for my parents.
First of all, don't waste your time connecting the ML-2525W as a USB printer. The printer will go offline after each print job. It's hopeless, at least (I assume) until Samsung gets around to publicly releasing a firmware update.
Instead, you have to use the ML-2525W as a wireless printer. In that mode, it works fine.
This is what I did:
(1) First, if you have already attempted to install the Samsung driver software from the included CD-ROM, uninstall it. Get the uninstaller from the Samsung support site:
http://www.samsung.com/us/support/downloads/ML-2525W
Download the "Printer Driver (ver. 4.0)" ZIP file. It unzips to a folder that contains the uninstaller. Likewise, download the "Smart Panel Driver" ZIP file and uninstall the Smart Panel software.
(2) Disconnect the USB cable from the printer, if it is connected. Pull the power plug on the printer and power cycle it.
(3) Restart your Mac.
(4) Go to the "Printer Driver (ver. 4.0)" folder that you previously unzipped. Inside it is a folder named "WirelessSetting". Open the folder and run the "Wireless Setting.app".
(5) The application will ask you to connect the USB cable to the printer. Do so, and the Mac should be able to communicate with the printer to perform the wireless setup.
(6) The application will show you a list of wireless networks. One of them is the wireless interface in the printer (ad-hoc). You can ignore that unless you intend to use the printer without connecting to another wireless network. In my case, I selected the wireless network in my parents' home (infrastructure) and entered the security passphrase. The application then configured the wireless interface in the ML-2525W to connect to the home network.
(7) The Wireless Setting application will then tell you to disconnect the USB cable.
(8) After finishing the Wireless Setting application, go to Word, Textedit, Pages, or Safari, and select a file or page to print. In the print dialog window, you should see the ML-2525W as a "Nearby Printer" (i.e. via Bonjour). Select the ML-2525W, and your Mac will automatically connect to Apple's Software Update and download the latest Samsung driver. If for any reason the Software Update download does not succeed, you can manually download and install the Apple driver using the previously published link in this discussion.
(9) After that, you should be able to print to the ML-2525W whenever you want, without the printer going offline.
(10) If you have a USB printer queue still in your Print & Fax Preferences (from your previous unsuccessful attempt to connect via USB), you can delete it. You only need to keep the Bonjour queue.
Obviously YMMV, but in my case this procedure got the printer working reliably without the need for a firmware update."
