Do you have a project open when you are doing this? Many of the menu items are disabled unless you have a project open.

I do, and it's not the tools -> import that is disabled, I can actually get to the import screen, however the open dialog from mac shows greyed files not allowing me to select anything

It is working for me. Make sure your files have the .ev3b file extension. These are the only files that can be selected.

They have the proper extension, something is wrong with this install. I tried on a different mac machine and it's working. Not sure what else I can do. I'm asking support to see if they have any ideas (I have already uninstalled and installed it again with no luck) Thank you

# EV3 Home edition for Mac missing import block option

(Asked by: username_0 on 2018-01-27)

I'm running EV3 HE 1.3.1 on macOS Sierra 10.12.6, and I'm unable to import the ultrasonic sensor.

When I open tools -> import block -> browse, the open button is always disabled, it does not allow me to select any folder.

Is there a command line utility to import the blocks perhaps?

Stuck on this for a while now.
