You must wipe the drive and reinstall OS X. In the future, you need to stay away from the data in the system until you know what it is and the consequences of the removal.

Install or reinstall OS X from scratch

Make sure that you have backed up your files because the following procedure will remove all of the hard drive.

HD recovery start:

Restart the computer after the ring, press in and hold the COMMAND and R keys until the menu screen to appear.

Erase the drive:

1. select in the main menu disk utility and click on the continue button.

2. once the charges of THE select your boot volume (usually Macintosh HD) in the

list on the left. Click on the Erase tab in the main window of THE.

3. set the type of format Mac OS extended (journaled). If necessary, click

Security and button all the option data from scratch in a single pass. Click

the clear button and wait until the process is complete.

4 leave FROM and return to the main menu.

Reinstall OS X: Select reinstall OS X and click on the install button.

Note : You will need an active Internet connection. I suggest to use Ethernet if possible

because it is three times faster than wireless.

This should install the version of Mac OS X that you had installed it.
