android - Trouble connecting to LG phone with adb (Mac OS X 10.7.5) -

when run adb devices there no devices showing connected. device lg optimus exceed 2 running 4.4.2 there many of these posts around, here's i've done:

i'm using cord came phone. charges , tries sync photos, isn't issue here. switching usb ports , trying powered usb hub doesn't impact either. i've added vendor id (0x1004) ~/.android/adb_usb.ini restarted , unplugged combination of things can think of usb debugging on. , has been restarted. same unknown sources. i have never used easytether, nor installed anywhere on computer. updated adb, updated sdk. restarted adb server tried installing lg's drivers: http://www.lg.com/us/support-mobile/lg-vs450pp (they don't back upwards mac s/w upgrade, yet have bundle install. no help there) i have nexus s running 4.1 works, , old lg phone running gingerbread connect.

any wizards out there who've struggled have advice?

i tried of connection types (charge, mtp, ptp) perhaps not "internet connnection, modem"? can alter pulling downwards system-wide drop downwards menu , touching "usb connection".

this how fixed it, thought i'd tried already, can't guarantee wasn't in conjunction 1 of things done above.
