MBED studio Target just says" loading" will not allow me to compile or select my board

I have been working on a project for several weeks and today when I opened mbed studio It would not detect my stm32 nucleo board from any usb ports. It also will not allow me to complie. Should I uninstall and redownload? I would rather not because I will have to go refind the libraries I have been using but is there any solution to this? I am on mac OS btw.


  • Issues around Mbed Studio are good to place under the Mbed Studio section
  • reinstall will not affect your projects

I had same behavior during the last friday, it was solved after PC restart. Windows10 with MbedStudio 1.3.1
It seems like something is not correctly ended on the background.
