I just upgraded to Mountain Lion 10.8.2 and lost all of my iCal appointments

Any idea how to get them back?

Do you have any backups from before the upgrade? If so, you can restore your calendars from backup. If you use Time Machine for backups, quit Calendar and then choose Go To Folder from the Finder's Go menu and enter:
~/Library/Calendars
When the window opens, open the Time Machine app or choose Enter Time Machine from the Time Machine menu, go back in time and restore everything in that folder.
If not, without knowing exactly what happened, there's not much we can tell you. I'd advise you to make an appointment at the Genius Bar at your local Apple Store.

I just upgraded to OS Mountain Lion 10.8.2 and lost all of my appointments on iCal.

The whole calendar is blank--no appointments anywhere. I have my system backed up via Time Machine and my calendar on my iPhone is fine. How do I get it back to my desktop. Does iCloud matter?

Just upgraded to mountain lion and my HP Laserjet p1102W won't connect

Just upgraded to mountain lion and my HP Laserjet p1102W to print (worked fine via USB with Snow Leopard; I never had set it up wirelessly, though had wanted to do so.) HP site said if printer worked with Snow Leopard nothing would need to be done; update of drivers would be automatic within Mountain Lion upgrade. No such luck. My Macbook Pro and HP Printer are not talking to each other. HELP, please!
I have a Macbook pro.
When I tried to print, I was told to get new drivers from HP. HP site says what I wrote above, that I need do nothing if printer worked with Snow Leapord. Also read that a new HP Laserjet would need to be connected only via Airprint. So, I have deleted the printer from the print queue, thinking that might help, but I can't find how to install it via Airprint?? After deleting the printer and having no luck with connecting wirelessly, I tried plugging in USB from printer to MacBook pro, too, thinking maybe that would help, but there is no recognition at all.
What am I missing???
Thanks!

Airprint is for IOS devices and thus has no relevance to this issue.
Connect the printer to your Wireless Network and use Bonjour to detect nd connect it.
That's wrong. AirPrint is not just for iOS devices. Since HP doesn't provide drivers for this printer, they say to use AirPrint:

I just upgraded to mountain lion. I am unable to use airplay mirroring through my apple tv. They are both on the same network. It says a airplay icon should appear in the menu bar but it isn't there. What am I missing here?

stevie, a third party app called airparrot will give you the pretty much the same as mirroring and forks on Macs too old to mirror.

I have just upgraded to Mountain Lion and my signatures for my Mail is not showing up. I have the signatures inthe preference panes and selected for the email address, but when I make a new message, the signature shows as none and doesn't give me a choice

I have just upgraded to Mountain Lion and my signatures for my Mail are not showing up. I have the signatures inthe preference panes and selected for the email address, but when I make a new message, the signature shows as none and doesn't give me a choice. Yesterday, the signatures were stacking instead of switching to the one I wanted to choose.

I had this and fixed it.
I had upgraded to Mountain Lion and my signatures in Mail were fine. But then about a week later, I got a new computer and used Migration Assistant to copy my stuff to the new machine. Upon opening Mail, I had all the correct Signature information in the Preferences>Signatures window, but nothing worked.
After lots of hunting, I found the Signature Folder. It's in:
Yourusername>Library>Mail>V2>MailData>Signatures
Looking at my previous setup (which works) I saw in that folder two types of files: .webarchive and .siganture
Looking in my new machine's Signature folder, I saw only the .webarchive folders, not the .signature folders
Since this was literally a clone of my previous setup to a new machine, here's what I did:
1. Quit Mail
2. In Problem machine, go to
Yourusername>Library>Mail>V2>MailData>Signatures
3. Move the Signatures folder someplace safe, but out of the MailData folder
4. Get the Signatures Folder from the working install (like a backup) and copy it to the MailData folder on the problematic machine
5. Start Mail on the problem machine
This worked for me. I don't know why Migration Assistant didn't copy the full signature folder, but this fixed it. It worked perfectly partly because I had just backed up with Carbon Copy Cloner and the very next day set up the new machine. I don't know where Lion or earlier versions of mail stored signatures, but the absence of the .signature filetype seems to be the problem.
Hope this helps

Can you check system update? I think I did a system Update 1st, a day before installing OSX Lion and there is a Safari update. If not try logging in iCloud.

Buffzap,
Make sure that you choose Mail>View>Show Mailbox List, then hover your cursor over one of the subordinate mailbox categories, and you should see "Show." Next click on "Show."

Where are you seeing that information? Got a link?
According to the Adobe website: Mac OS X Mavericks (10.9) compatibility FAQs | CC, CS6, Acrobat
Plenty of people, including me, are currently running CC on Mavericks.

Here is a recent post I assembled for a similar question:
Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
Workarounds:
1. If your Mac will support it, restore OS X Snow Leopard;
2. If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between your PowerPC software or Lion/Mt. Lion;
3. Upgrade your software to Intel compatible versions if they are available, or find alternative software that will open, modify and save your data files;
3. Install Snow Leopard (with Rosetta) into Parallels:

I Just upgraded to mountain lion os x to 10.8.1 and I have a problem with restart my computer

I Just upgraded to mountain lion os x to 10.8.1 and I have a problem with restart my computer.
Now my computer is stuk on restart and wont turn on.
Can somone help me with it?
Thanks.

If Mende 1's suggestion doesn't solve it you might find the following useful:
I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Hope this helps

I just upgraded to Mountain Lion and when I turned around I noticed my Stickies were gone

I just upgraded to Mountain Lion and when I turned around I noticed my Stickies with all my secret computer codes and passwords etc. were gone. I think they are attached to the application and were replaced with the upgrade with a new version...n'es pas?

Came here looking for a solution to this same problem and presume others will.
I found it somewhere else but just want to share the answer!
go to the SPOTLIGHT search and type in Stickies.
The app is still on your mac, it just doesn't show in the dock or the Launchpad.
It opened and all my lovely notes appeared as they were in my Lion install.
have a nice day!
