title: ADB server version (36) doesn't match this client (39); killing
body: <p>After installing the Android O preview on a test device my ADB stopped working and started giving me this error.</p>
  <pre><code>adb server version (36) doesn't match this client (39); killing...
  adb E 03-27 08:01:55  2925 147690 usb_osx.cpp:333] Could not open interface: e00002c5
  adb E 03-27 08:01:55  2925 147690 usb_osx.cpp:294] Could not find device interface

  ADB server didn't ACK

  <p>The only answers I have come across on this issue referred to Genymotion being out of sync with ADB but I don’t use Genymotion. Any help would be greatly appreciated. I have already wiped and reinstalled Android Studio as well as all of its tools and settings yet seem to still have this issue.</p>
