Startup failure on MAC/OS Darwin due to Python 3.6.1?


I talked to Joachim here in New York. He encouraged me to get in touch.

When trying to launch the software on MAC/OS Darwin, I get the following error message:

Domenicos-MacBook-Pro:~ ziolai$ /Applications/
dyld: Library not loaded: @executable_path/…/Frameworks/Python.framework/Versions/3.6/Python
Referenced from: /Applications/
Reason: image not found
/Applications/ line 10: 6744 Abort trap: 6 $Netgen_MACOS/netgen

I am using python 3.6.1

Domenicos-MacBook-Pro:~ ziolai$ python
Python 3.6.1 |Anaconda 4.4.0 (x86_64)| (default, May 11 2017, 13:04:09)

Any thoughts? Sincere thanks, Domenico Lahaye.

Any thoughts on the matter? Thanks, Domenico Lahaye.

Hi Domenico,
I’m not a mac user, but I remember we had troubles with Anaconda Python in the past… Could you try disabling Anaconda and installing default Python? Note that although Python 3.7 is available already we still build the installers against 3.6, so you need to get 3.6.

Hi Domenico,

we need Python from the Python-3.6 dmg as given in the installation instructions.

The NGSolve - installer does not work with anaconda yet - Matthias, any comment’s on that ? .


Thank you for getting in touch!

Not sure how to disable Anaconda. I will await news.
