Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate... (the same happens with the other iWork-Apps!)
Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers

Problem with iPad back up after installing Mountain Lion.

Since installing Mountain Lion, the camera roll on my iPad does not download pictures. It's a first generation iPad. Is it not compatible with Mountain Lion or is there something I can do?

Searching communities I found an Apple page Image Capture. So I opened it with my iPad connected and the pictures were imported. I still don't know whether I will have to do this every time or whether it has unblocked it!

Does this mean my imac is dying? only had issues after installing mountain lion:

There is one thing you can do to try to determine what's consuming that space. Launch a Terminal session, then type this command:
sudo du -d 1 -h -x /
and press <return>. You'll be prompted for your administrative password, which won't be echoed as you type it. Press <return> again after you type the password.
The output will show one line for each file or directory at the top level ("/") of your disk. That will give you a first-cut picture of what's consuming the space.
Here are the things on my system that have a non-trivial amount of space:
975M /.Spotlight-V100
15G /Applications
17G /Library
5.8G /private
3.8G /System
37G /Users
606M /usr
For more details on a particular entry, just put its name after the slash on that command, such as
sudo du -d 1 -h -x /private

Serious wifi problems with iMac after installing Mountain Lion

After installing Mountain Lion, I'm experiencing serious trouble with wifi. I noticed that some people had this before with Lion. Can anybody help to solve this problem or should I downgrade to Mountain Lion?
Please help
Thanks in advance!

Thank you for the information Arizonadonn! I'll install 10.8.1 this evening. I really hope you're right after having connection troubles for almost a month now .
If this solves my problem, you'll be my hero !

Bluetooth inactive after installing mountain lion - your computer restarted because of a problem

Good day
I read up on forums, and I think my reboot error is due to my bluetooth that is inactive, which happened after installing Mountain Lion
My Bluetooth worked before under Snow Leopard
I have deleted the file under library to no avail
I have rebooted with cmd option P R to no avail
I have repaired permissions and this is the only message that pops up, and bluetooth still does not work after reboot.

Please assist and I hope my thinking is correct that this is what is causing my restart error.

I have been having the same problem for the past 2 days.I installed Mountain lion 5 days ago.There wasn't any problem for the first 3 days but after that my computer won't shut down,it always restarts when i ask it to shut down and i get the same message as dan1101.what is going on????

Many of my System Preferences will no longer work after installing Mountain Lion. Software update, startup disk, iCloud, etc. no longer will launch. I keep getting a drop down window saying I must restart system preferences in order to use. No go!

Many of my System Preferences will no longer work after installing Mountain Lion. Software Update, Startup Disk, iCloud, Time Machine, Notifications, etc. no longer will launch even though they do show their icons in the system preferences window. I keep getting a drop down window saying I must restart system preferences in order to use with a "Cancel" or "OK" choice. After I click on "OK" the window just keeps reappearing with the same choices and the pane I wish to use still remains inoperative. Third party preference panes DO work.
Reinstalling OSX Mountain Lion did not help. Neither did throwing away preferences.plist.

Hi Jeff,
Tried to reply with my iPhone but not easy! Anyway, back on the laptop now. Yes the crash was bad but Tek support at Prism Sound was really good. In the end I rebuilt the whole system on a new disk which took a couple of days with all the plugins, softsynths etc.... but there seemed to be no alternative in my case, and this was agreed with Prism sound as being the only alternative left to me. I still don't really know what caused the crash but ML and Orpheus are both working fine now. Let's face it, you'll have to update at sometime..maybe best to pick some time between projects On balance, I suspect that my problems were unique to my system and that your installation will go ok.
Hope it goes well,
Rick

Does anyone have an email client that is working with Mountain Lion? I'm giving up on Mail after installing Mountain Lion

Hi
I give up. I just cannot see my exchange inbox in Mail after installing Mountain Lion. My mail is not being deleted. Its still in my inbox I just can't see it. I've tried everything suggested on the forums and nothing is working for me.
My productivity has completely stalled and I really need to move to an email client that is going to work seamlessly with Mountain Lion.
Any recommendations?

I have been having the SAME problem with ALL my Gmail accounts with Mail.app - It is very annoying, especially when you have clients and other important email to respond to. So you're definitely NOT alone in this department.
Might have to go back to Thunderbird or something until this gets fixed, which is going to really suck because I have 5000+ emails along with all my Email Folders in Mail not too mention the Rules I have had setup for years!
AND with the RSS Feeds NOT working in BOTH Mail and Safari! That was a HUGE MISTAKE and defintely a STEP BACKWARDS on whoever's idea that was for sure!

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

Imac does not recognize my usb after installing mountain lion

My imac don´t recognize my usb after installing mountain lion, also don´t let me see all my photos in jpg format

What is "my USB"? If it's an external USB device, is it ML compatible?
Which app do you use to open JPGs? Is it ML compatible?

Can No Longer Get Camera Photos After Installing Mountain Lion

After installing Mountain Lion, I am no longer am able to see pictures from my digital camera thru the USB port. This camera has worked for years with my iMac, but not anymore. Anybody else having this issue after installing the newest system?
Dick

Paul_31:
I have not tried to import the photos directly into iPhoto. However, I did remove the SD card from the camera and plug it into a USB card reader, and my iMac would NOT read the photos that way either. I took the camera and plugged it into my Win. 7 laptop and the pictures showed up nicely, so I know the camera and the card are Ok. My iMac has been working strangely since I installed Mountain Lion. I'm getting lockups using iMovie too.

No video after installing Mountain Lion

I have downloaded and installed Mountain Lion on my Mac Pro. After the install and restart, my Mac Pro restarts however, I do not get a signal sent to my monitor. I have attached different monitors and connected to both DVI ports with no luck.

I just wanted to add to the conversation that this was EXACTLY what happened to me after installing Mountain Lion. All my contacts were gone. It showed the Groups on the side of the address book after one day but the contacts never showed up. I tried unchecking the box for the contacts in system preferences for the iCloud and then rechecking it again. That didn't help either. Came across this remedy up above about taking the Address Book from the Application Support Folder and putting it in the trash. Viola! It worked. However, I would add that I had to go into the iCloud pane and check the address book box since it then became unchecked. Once I did that, they ALL loaded back up and now they are finally there.

Ethernet connection issues after installing Mountain Lion

After installing Mountain Lion I can't get my iMac to connect by ethernet. It says that no cable is connected. The cable/connection is fine. When I plug in my MacBook Pro running Lion, the ethernet connects just fine.

same exact problem. in fact, my iMac24 (2009) worked flawlessly until I installed the latest update to Mountain Lion. I then checked my MBAir (2011) and it too has a problem when using the USB/Ethernet adapter. Neither can get an ethernet connection. I deleted my network preferences and rebooted my machine, played around with my Ethernet switch and even reboot my gateway/router. I've never had to do any of this to my network until Mountain Lion. Wireless is the only thing that continues to work on both machines.

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

Standard problem in ML.. apple do not seem to want to recognise.
Reboot the TC .. if that fails restart the whole network in correct order.. modem.. router/TC... clients.. with 2min gap.
There are other suggestions like changing the password.. all they do is the same as reboot.
Read C12.. most quoted Q in pondini website history. This is asked 10 times a day.
http://pondini.org/TM/FAQ.html
Here is another way to get a useful utility in ML.. rather than toyland version.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.
