After installing maverick, finder not responding!

Question

Hi everyone,
Yesterday I installed Maverick on my Macbook Air and then i lost my desktop! I use Lion 10.9.1. Now the finder is not working. When I right click on it on dock, it doesn't allow me to open it. at the top of list it says ''application not responding''. The only way for me to access the top bar is by opening other app such as safari. The fans are also making a lot of noise. I tried to log in as guest and nothing has changed! I need help.. thank you!

Answer 1

Start with the steps below. They may or may not solve the problem.
Uninstall SIMBL as follows. Back up all data before making any changes.
Triple-click anywhere in the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/Library
In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V), and press return. A folder will open. From that folder, delete the items listed below (some may be absent.) You may be prompted for your administrator login password.
Application Support/SIMBL
InputManagers/SIMBL
LaunchAgents/net.culater.SIMBL.Agent.plist
ScriptingAdditions/SIMBL.osax
Log out and log back in.
Make sure you never reinstall SIMBL. It’s likely to come bundled with another third-party system modfication that depends on it. If you want trouble-free computing, avoid software that makes miraculous changes to other software, especially built-in applications. The only real exception to that rule is Safari extensions, which are mostly safe, and are easy to get rid of when they don’t work. SIMBL and its dependents are not Safari extensions.
Launch the Font Book application and validate all fonts. You must select the fonts in order to validate them. See the built-in help and this support article for instructions. If Font Book finds any issues, resolve them.
From the application's menu bar, select
File ▹ Restore Standard Fonts...
You'll be prompted to confirm, and then to enter your administrator login password.
Boot in safe mode to rebuild the font caches. Boot again as usual and test.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. In that case, ask for instructions.
Also note that if you deactivate or remove any built-in fonts, for instance by using a third-party font manager, the system may become unstable.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2>&-
This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not  going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.
