The low battery warning doesn't display on my MacBook Pro Retina 15-inch Late 2013 .
I had tried following suggestion from apple. that is go to "system preferences>energy saver>check show battery status in menu bar " and it's not helpful for me. The warning still not display even on 9%.
MACBOOK PRO (RETINA, 15-INCH, LATE 2013), OS X Mavericks (10.9.1)
