Android : Android Device doesn't show up in Eclipse

Believe me, I know there are a TON of these posts in SO, but I've gone through most of them and have yet to find a solution. Some notes:

1. I'm running Mac OSX Yosemite


2. Both my devices are USB-debug-enabled (rooted HTC One X, and Motorola Moto G)


3. On both devices, I have successfully run the app via Eclipse before (in fact the HTC is my main testing device)


4. My usual method when the device fails to appear is to quit Eclipse, then run adb kill-server killall adb and then restart Eclipse.


5. This time that method didn't work. I've also tried restarting the phones, and restarting Eclipse multiple times.


6. Running adb devices shows the device there (the device's ID, and 'device')


7. I've checked the SDK Manager, just in case there were some magic Mac drivers that I could use. Nope, so such luck.

Anyone got any ideas for this?
