Py3 Mac app for testing

[peterl94]

Thanks to the great work looo has done with conda packaging, I was able to put together a mac app using python 3.6. I only used conda for installing the dependencies and compiled the app manually. Eventually it would be good to be able to create an app from the freecad conda package. Anyway, here is a direct link if you want to try it out: https://github.com/FreeCAD/FreeCAD/rele ... t5-Py3.dmg. It might work on macOS versions as far back as 10.9. Interestingly the .dmg increased by 200MB, but I haven't looked into why.

I hadn't really considered changing to using conda instead of homebrew for macOS packaging, since homebrew is pretty standard for developers using macOS. However, with the change to py3, and all the required packages already available with conda, and my very limited time....it is sounding like a pretty good idea to me right now.

This is great! All workbenches are working again (Path, Draft, Arch). From my side it could well replace the current 15310.

congrats @Looo and @peterl94 Nice to see a OSX version again!!

@peterl94 and @loo - well done. I'm onboard with this for all platforms as I stated here about a week ago - https://github.com/FreeCAD/FreeCAD-AppI ... -450514116 and in some back and forth with peterl4 and looo. Resurrecting Homebrew builds is within https://travis-ci.org/FreeCAD/homebrew- ... /473602650 but I am a firm believer, if possible, that we should invest in a singular, cross-platform solution over more redundantly laborious platform-specific solutions to efficiently maintain cadence across platforms. Of course, @looo's spear-heading of Conda illuminated the possibility of such a path early on...

I am not sure what triggers it, becuase it usually happens when I am doing nothing, so perhaps it has to do with the autosave mechanism or some other timer triggered event.
I sometimes get the error message

I think it's mostly libmkl, similar on Win.

Indeed! ~580MB.

I'll see what I can find. I wonder why it is not a problem on linux.

thanks @peterl94 for your efforts to create a mac-bundle.

Some thoughts on the creation of the bundle:
1. when you create the environment use an additional constraint: blas=*=openblas
This will make sure openblas is used instead of mkl. (mkl is very big in size)

2. conda ships static libs and shared libs together. For the appimage we remove all the static libs after the env-creation. Maybe this works also for the mac-bundle: https://github.com/FreeCAD/FreeCAD-AppI ... .sh#L33L34 (Also removing unnecessary stuff from bin and include should result in a smaller size)

3. Maybe it's also possible to ship calculix within the bundle. (The package is not very big: https://anaconda.org/conda-forge/calculix/files)


Btw.: I am still using a patch for osx-builds.
1. https://github.com/looooo/freecad-feeds ... /osx.patch

Did building FreeCAD without this patch worked for you? If so I will try to remove it for the next weekly conda-build.

I might add that this does not lead to any further problems.
