"Fastboot devices" command doesn't work after macos high sierra 10.14.4 upgrade I recently upgraded my 2016 MacBook Pro to High Sierra 10.4.4 update and since the update "fastboot devices" command hasn't been working. "fastboot" itself gives a response but "fastboot devices" command gives 
ERROR: Couldn't create a device interface iterator: (e00002bd)
ERROR: Couldn't create a device interface iterator: (e00002bd) error. It comes twice on the window.
This might be a regression in android-platform-tools. Try fastboot version 9dc0875966c0-android from android-platform-tools 26.0.1 as it works for me on macOS 10.14.4
