Calendars and event data lost in mountain lion upgrade from snow leopard on mac book pro

I just upgraded to mountain lion today. It appears my contacts and emails were transferred without loss to the new system but all of my calendar data and the calendars themselves have disappeared. Does anyone know how I can get my old calendars and event data back? I backed up my laptop on time machine before doing the upgrade, so my old calendars should be on my external hard drive. I'd like to simple recover the data from the laptop if it is just hidden somewhere. Alternatively, if someone could tell me how to import the backed up calendars back in that might be a good plan B. I also still have the old calendars on my iphone which I am afraid to sync for fear of data loss.
I looked through previous responses in the community to this same question and I tried deleting the account and adding it back in but that did not work. Any assistance would be appreciated. Apple support is giving me an cold shoulder that is rather unexpected given my past good experience with Apple support. Bummin out over here

Which way do you reinstall OSX?
I would go through the recovery partition, check Disk there and then run the installer. make sure you have a reliable connection the the Internet.
This could be a third party app you have running in the background that is crashing. what exactly is crashing ?
are you getting kernel Panics?
You are not able to simply roll back to Snow Leopard, you will have to have a SL disk, and then erase and install SL onto you hdd/ssd. This will erase ALL of your data so I hope you have a Time Machine backup or bootable clone.
I believe your issue is with a third party application installed.
More information is needed.
Call 1-800-My-Apple or file a dispute here https://expresslane.apple.com/Issues.action
On a personal note, I think you are missing out on ML and need to figure out if there is an application running that is causing ML to crash.
Usually a reinstall fixes my issues.

Running mountain lion os 10.8.5 on mac book pro mid 2012 build. If I upgrade to Mavericks will MS Office programs still work?

I am running mountain lion os 10.8.5 on mac book pro mid 2012 build. If I upgrade to Mavericks will MS Office programs still work? There does not appear to be an updated version of MS Office for Mac past 2011 that I bought last year and am using now. Thoughts? Suggestions?
Thanks.

Office 2008 and 2011 will run on Mavericks, but you may not be able to get the installer for it at this time.

As the others have stated, you're on Mountain Lion with 10.8, anything. But you can check your version of the software by going to the apple in the upper left corner of the screen and clicking it and selecting "About This Mac". That will open a box that shows your software version. Once there you can click on "More Info" that will tell you everything about your specific mac configuration.

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?
Is this because of hardware changes? Or firmware changes? Or is it just and Apple Inc. administrative fiat?

@Steve Holton: Sorry Steve, but you're wrong about that one . I'm using 10.8 (purchased and downloaded) on the internal HD of this MBP8,3 (2.2 GHz, 17"), and I am also able to boot into 10.7.4 and 10.6.8 from external FW800 partitions.
However, I DO have problems with my MBP9,1. It came with 10.7.4 installed and ran fine. Then I purchased and installed 10.8. It ran fine but could no longer boot from 10.7.4 on an external partition. I then reinstalled 10.7.4 on the internal HD and discovered that it is still unable to boot (even 10.7.4) from an external FW800 partition.
One of Apple's Senior Support Advisors has done some remote troubleshooting but the case is still open and unresolved. An earlier Apple Support case suggested that when, I installed the downloaded copy of 10.8, there had been a "firmware update" (behind the scenes) that is now causing the problems with booting from my external partition(s). This apparently is "a bug": it is not what is supposed to happen.
So - I believe - "the problem" really has nothing to do with hardware capability. It is strictly about Apple's strategy for "managing its future customer base". If you don't like it - use something else - I am seriously considering Ubuntu as an alternative.
If there's a hidden caveat in all this it's probably "Read Appple's Licence Agreement VERY Carefully".

Purchased Mountain Lion upgrade for Snow Leopard ... but ???

I paid my $19.99 and went through the process, but after my computer restarts the Download mountain Lion icon is still there, space on my hard drive is used and when I go to "About This Mac" it still shows that I'm running 10.6.8 and the Snow Leopard ico is still up on my desktop. I am computer clueless and that's why I run a Mac... now I'm baffled too... HELP!!!!

Another curious thing, to me anyway, is that the 4.46 GB has disappeared from my total amount of available GBs, yet I can not seem to locate where it is stored... perhaps that is a simple thing, but not to me. Thanks all.
In an earlier post you said that the installer file was in your Applications folder and that it was 4.46GB. Are you now saying that is no longer the case?
Yes.. mine is 4.46, but yes.
In reply to this.
Do you still have this in your Applications folder? (Your copy will not have the green checkmark)
And is it this size?

It seems your MacBook is too old to run Mountain Lion. But given the age of your Computer, Snow Leopard is still a very stable and excellent OSX. You can go to Lion (10.7) if you wish, but if I were you, I would be staying with Snow Leopard.

Migrate the mountain lion upgrade the snow leopard personal items

this is my question

If you install Mt. Lion over Snow Leopard, your data will not be changed. Is that your query?
Regardless, a backup is useful to have at all times.
Ciao.

I can't sync iCal from my Mac (MBP) to my iPhone. I recently upgraded from Snow Leopard to Mountain Lion and I think that's when my iCal stopped syncing from MBP to iPhone. Help please!

Does anyone know how or correct this problem? Before the Mountain Lion upgrad (from Snow Leapord) I didn't have this problem. Now, my iCal on the phone seems locked or frozen, and any additions I make to my MBP do not sync to my iPhone. Really frustrating!

Well, you can try this: right click the file, go down to encode file, and reencode it for the Mac.

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this?

First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

!!!HI, SO I BOUGHT MOUNTAIN LION ON MY MACBOOK PRO TRYING TO UPGRADE FROM SNOW LEOPARD, AND WHILE TRYING TO REINSTALL THE OS SETUP AS IT SHOWED IT COULDNT BE VERIFIED, I CROSSED OUT MOUNTAIN LION FROM MY PURCHASES, ITS NOW GONE, DO I HAVE TO BUY IT AGAIN?

Please google search for "Mountain Lion disk crash" before upgrading you mac pro. You might need to replace you Mac hard drive after the upgrade.So many people had the same problems including me.
Be aware of the Mountain Lion upgrade problem.

I just upgraded from snow leopard v10.6.8 to os x mountain lion and my scroll bar has disappeared on all my applications on the internet. does anyone know a patch to get the scroll bar to work.

Open General preferences in System Preferences. You can set the desired scrollbar behavior there.

I recently downgraded from Mountain Lion back to Snow Leopard and I forgot to export my bookmarks.

Unfortunately downgrading from Mountain Lion back to Snow Leopard means I need to wipe the hard drive and install everything from scratch. That takes hours, and I've already done the bulk of the work, twice actually since I forgot to back up my photos in Iphoto and had to start over from my Time Machine backup of Mountain Lion.
Anyhow, I am curious as to whether or not there is a way to retrieve my bookmarks from the Time Machine backup and get them onto my downgraded OS, or will I have to start all over again, restore my system to Mountain Lion and go through the hours it takes to get back to Snow Leopard.

You're missing the point. If you didn't make the /username/Library/ folder visible, then it's hidden on the TM backup. Getting to ii is beyond my ken. However, Pondini's TM FAQs might have info on that madness.

I've just upgraded from Snow Leopard to Lion. Installation seemed to go OK but on rebooting it is asking where the System Events app is. What is it and where is it located?

If the dialogue appeared once, and you cancelled once, the dialogue may reappear when you next log in. For more certainty I suggest a restart of the operating system, then a log in.
If you like: immediately after the problem is worked around, open the Console utility to see whether — amongst its view of all messages — there is an obvious sign of what caused the dialogue to appear. (If you see nothing obvious, don't waste too much time looking.)

If I upgrade from Snow Leopard 10.6.8 to Mountain Lion, will I lose Microsoft Office and iMovie?
