When awakes after sleep MB frezees, wifi can´t get active, dock does not show, in general MB does´t respond. All this after I installed an update of mountain lion.
Try starting up in Safe Mode and see if things are better.

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, Chrisyou 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 -
Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!We're sorry.

After installing Mountain Lion, I tried to scan from my Canon MX870 and received the message: "MP Navigator EX quit unexpectedly. Click Reopen to open the application again. A report will be sent to Apple," This problem happened right after I installed Mountain Lion. I then downloaded Canon's upgraded software and drivers for the MX 870 and the problem was resolved. Now one month later, the problem has returned.

Solved problem with original Canon software. When I downloaded Canon software upgraded for OS X 10.8, I got all by Navigator Ex. Noticed that on Canon's site, the upgraded version is 3.1; my app was 2.1. Upgraded to 3.1 for Nav. Ex, and it works.
You should still use Image Capture IMHO. If it was my gear, that's what I would do. No need to worry about software upgrades. -
after installing mountain lion I lost pictures in iphoto, lost my musisc in itunes, my icluod is not working, internet its very slow and some other issues. There is a way how to fix these issues
Open System Preferences > iCloud
Deselect the box next to Photo Stream then reselect it.
Now for your music. Launch iTunes. From the iTunes menu bar top of your screen click iTunes > Preferences then select the Store tab.
Select: Music. (and Apps and Books) if you want.
Click OK.
iCloud syncs via your Wi-Fi network so give it a minute or two to reset your photos and music.
Slow internet ... try turning off the modem for a few minutes, then turn it back on. -
After installing Mountain Lion on my Mac Book Pro, I can no longer access two shared drives. Diagostics cannot solve the problem. I am using Parallels to run Qucikbooks ERP on these shared drives. How do I get my Mac to see these drives and access them?
Don't know what to tell you, but I also have an AEBS-Gen5 with a MBP Retina and Mac Mini using WiFi. Both are running Mountain Lion and I don't have any WiFi connection issues. Two iPhones in the household use WiFi with no issues along with a printer and 2 Windows 7 laptops.
First thing I would try is to shutdown all computers connected to the AEBS. Then power off the AEBS and finally the cable/DSL modem. Then reverse the order and power on the cable modem, wait for all the lights to be solid, power on the AEBS, wait for the light to show solid green; then power up a computer that uses WiFi.
If the above doesn't work, you might try repairing permissions via Disk Utility. If that doesn't help maybe a PRAM reset would work. -

After installing Mountain Lion on my 17" MBP G-RAID mini connected via Tempo SATA Edge ExpressCard34 is no longer recognized. I restored icon and access by removing 34 card and substituting FW800 for eSATA. Any fix for the higher speed connection? TIA
Looks like the Silicon Image drivers were moved to the incompatible software folder during install/upgrade.
Downloaded latest drivers, errored out of install claiming that the drivers were from an unknown author!!!
Emailed their tech support this evening describing problem. -
After installing Mountain Lion. No sound. Under sound, where it says select an output device, it says no output devices found, and there is no sound. How do I fix this? I have reinstalled the os twice and still the same. I have also repaired permissions.

After installing mountain lion the local mail boxes disappeared
after installing mountain lion the local mail boxes disappeared.
This is my problem too:
All of my local mailboxes (On my Mac) disappeared from the sidebar. However, I do not have the 'triangle' on the Inbox that I can turn to reveal the list of mailboxes -- that disappeared too (and nothing happens when I hover over "Inbox"). I do know that the mailboxes are still there, somewhere, because when I go to create a New Mailbox, I can navigate to "On My Mac" and the entire mailbox list shows up there in the dropdown. How do I get them back onto my sidebar if the option to do that is no longer on the "Inbox" icon? -
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.

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. -
After installing Mountain Lion, I experienced a noticeable reduction in performance. When I log-in, I must wait several seconds for the cursor to become effective in the log-in window. When I come out of standby mode, I have the same issue. Also, when looking at cpu usage, Outlook appears to be using up to 67% of cpu when not doing anything. I'm not happy with this result.
Does anyone have suggestions as to how to fix?Uninstall Office and reinstall it
Use these instructions to do it and do not omit any of them.
