Can't open Preview/Calendar/App store/iBooks/Terminal/Mail after updated to Mavericks

Found the solution

http://mashable.com/2013/10/23/clean-install-os-x-mavericks/

I created a new user account under System Preferences - Users & Groups. Everything works well in the new user account. I will import my mail from my old user folder. No need to do a clean install.

Hi Robertzamora19, there is still no link to download Mavericks, the problem is I can not open App store now.

what osx are you in?update the computer. and the go to the app store and dowload mavericks

I created a new Guest user account, but the same, also can not open those apps from Guest user.

Thanks louiscuhk, I did as you said, it solves the problem.

Here is how to enter recovery mode: http://support.apple.com/kb/HT4718

To start your computer from Recovery, restart your Mac and hold down the Command key and the R key (Command-R).

sup, i have the same problem , its exactly what i did, all the **** after i use clean my mac, i think that is the problem , its te 3rd time that i reformatted my macbook pro retina 15 ¨mid 2012

I'm having the same problem but I've got a few question:

1. My Mac previously had Snow Leopard, can i still use the Recovery Mode?

2. Do i need a bootable copy of Mavericks or will it be download again from the internet?

Sorry for the stupid question.

I had same problem. Darn 'Clean My Mac'. Re-installed Mavericks in Recovery mode. Took about an hour but all is well now. I guess I will not be using Clean my Mac for awhile. Thank you.

Airalan: You could try looking for a torrent file for the Mavericks app.

I called Apple, and after a good explanation and follow up of what I should do, I managed to fix the problem.

What to do to fix it:

• Reboot and hold cmd+R (get's your mac in recovery mode)
• Select Reinstall OS X, then click Continue.
• Follow the onscreen instructions. In the pane where you select a disk, select your current OS X disk
• DONE!

I wont be using CleanMyMac anymore I think.. (think CMM has caused me this problem)

Here a quick guide of a reinstall of Maverickx (this won't delete anithing of your personal files or apps!

OS X Mavericks: Reinstall OS X

Hope it helps!

Kind Regards!

I've done this twice now (with a total 5 hours of waiting), and sure enough the preview, mail, etc. function normally.

iWork however refuses to open (the new updated versions) and Time Machine "prepares" infinitely. I'm not sure if this is related or not, if anyone has similar problems or solutions please let me know.

Thanks for the good advice.

Just an update: Putting it in Trash made the App Store request a new purchase of Pages. Putting the app back into the Applications folder somehow prompted an update on the App Store.
