Why Is My Macbook Charger Blinking Green. Press the power button once to activate charging for your device 3. On the built-in keyboard press SHIFT-CONTROL-OPTION and the power button at the same time.

After doing that press the Shift Control Option Power keys from the keyboard up to 5 seconds and then release them. Why does my ooze pen keep blinking green. This time however the macbook wont start up the charger is a solid amber color for about 3 seconds before switching to a blinking green.
More than likely the battery is defective.

So last night i was using my Mac like every night and suddenly charger started blinking and it charged for 2 seconds and then didnt charge for 3 seconds and like that on repeat. Post to Twitter.
