If you are trying to login first at start up, it could be a failure to authenticate credentials on Active Directory only if your macbook is binded to the Active Directory.
If still hangs on Starting Mac OSX, there will be an issue with the local Library directory plist files. I recommend in this case to reboot and boot up in safe mode, then try to login again.
If this procedure didn't work use the login in single user mode Command-S, then run a check disk /sbin/fsck -fy then press enter.fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:

** The volume (name_of_volume) appears to be OK

If fsck found issues and has altered, repaired, or fixed anything, it will display this message:

***** FILE SYSTEM WAS MODIFIED *****

If the file system was modified you might have to reinstall your Mac OSX.

Good Luck
