Green LED is on. Yellow LED (L) was blinking when updalod worked. Now it is off.Bootloader
• Make sure there's a bootloader burned on your Arduino board. To check, reset the board. The built-in L LED (which is connected to pin 13) should blink. If it doesn't, there may not be a bootloader on your board.
If it still doesn't work, you can ask for help in the forum. Please include the following information:
• Your operating system.
• What kind of board you have. If it's a Mini, LilyPad or other board that requires extra wiring, include a photo of your circuit, if possible.
• Whether or not you were ever able to upload to the board. If so, what were you doing with the board before / when it stopped working, and what software have you recently added or removed from your computer?
• The messages displayed when you try to upload with verbose output enabled. To do this, hold down the shift key while clicking on the upload button in the toolbar.

Upload was working before and tried few sketches (e.g. blink) and were working.
-
Tried FTFIU.. driver for serial port. Found out it is not needed on Mac. Deleted driver from the system files and rebooted Mac.
-
This is what I get when uploading now.
