Made with Mu announced that the latest stable version of Mu is here!

Version 1.0.3 is a bug-fix release, mainly for Mac users, with no new features.

We didn’t intend to cut this release but changes in the way the latest OSX works meant that code highlighting didn’t work correctly. We also managed to apply a fix to an annoying bug relating to where Mu set the current working directory for scripts run in Python3 mode.

OSX Catalina posed a number of problems, from the incorrect rendering mentioned above, to the way the application should be installed and problems with permissions when flashing a BBC micro:bit.

The simple answer to the installation story is, once you’ve installed Mu in your Applications folder (OSX), you should first open it with CTRL-click (not a double click) and select the “Open” button in the resulting pop-up. Subsequent runs of Mu can be started in the usual “double click” way. If you don’t do the “CTRL-click” trick you’ll see a pop-up complaining about Mu not being checked for malicious software.

See the full details here and the video above.

Mu is Adafruit’s preferred editor for using CircuitPython.
