Marz Workbench not working on my Mac Os High Sierra

[Mojoberlin]

Working on mac os high sierra 10.13.6 with latest FreeCAD Version 0.20-1 and latest Marz Workbench v0.0.26-alpha. Using Python Version 3.10.5 packaged by conda-forge. I can launch the Marz Guitar Designer Workbench. I can also open a new instrument. I can see the new instrument in the model view. From here I have several options: create a fretboard or a neck or a body. In my Python Console I get the following message if I want to create a Fretboard, for example: "Gui.runCommand('MarzCmdCreateFretboard',0)"

As an example, if I now create a new fretboard I get the following error message:

File "/Users/michaelfreudenberg/Library/Application Support/FreeCAD/Mod/Marz/./freecad/marz/command/create_fretboard.py", line 47, in Activated

Hi @Mojoberlin I am sorry to hear that it does not work for you. But have you read the mac note in readme? Basically it is not supported on mac because I have never tested it on mac.

[mnesarco]

Looking at your error message it seems like a breaking api change in the progress indicator. I will review tomorrow. Maybe it is affecting all platforms

[Mojoberlin]

Hi @mnesarco thx for your time and your quick reply, maybe you will find a solution to the problem. If you need any additional information from me then let me know. 👋

[mnesarco]

There is no problem running it on Linux. So the problem must be specific to Mac or your environment.

[mnesarco]

I have added a temp workaround for MacOS.

As this is apparently solved by now, I am closing this.

Hi!
I have tried all above but can not get a body to load. I can launch the Marz Guitar Designer Workbench. I can also open a new instrument. I can see the new instrument in the model view.
osx 13.4.1
freecad 0.20.2-29603
marz 00.26 alpha

Your version is outdated, please try update to the latest 0.0.27-alpha

[kellander]

Hi!
Thanks for pointing me in the right direction.

here i find 0.0.25 alpha as "latest".
https://github.com/mnesarco/MarzWorkbench/tree/master

Is there somewhere else I download 0.0.27?

Found it - add-on manager.

Oh, yes, AddOn Manager should be used always.
