Weird Icon
I feel so slow... but my roommate has been using my mac when I've been at work and now of a sudden I have the weirdest icon. Nothing shows up when I click it either so maybe you guys can help....
It's in the top right between the bluetooth and chrome notification(the bell) icon.
Any help would definitely be appreciated, thank you!!
