MBED Remounter

Another workaround for the problem that HDK-based mbeds cannot be handled properly by a Mac rnning Yosemite. This is implemented as a launchd daemon that continuously watches the file system of your Mac. If the daemon finds that an mbed is connected, it automatically fixes the mount mode of the device so that you can successfully write to the mbed. Direct drag & drop copying to the mbed drive is also resumed.

  • Akifumi Okano for his droplet that inspired me as well as testing and advertising this software
  • Ned Konz for his nice regular expression that can retrieve required items only from the output of the mount command
You can’t perform that action at this time.
