pymakr on mac

  • pymakr is not willing to start at all, it just happens - nothing. Can you help?
    (Mac OS Sierra 10.12.1)

  • @Nils, welcome, thanks for your feedback :)

  • @abilio yes, that solved it! updated macports to the latest "sierra" version and then did a "port upgrade outdated" - now pymakr is running fine. thanks for the quick support and pointing me to the right direction.

    best, nils

  • @Nils, do you happen to have macports installed in your computer?

  • @abilio here it is, looks like libpng16.16.dylib is outdated, can i update this someway?

    Traceback (most recent call last):

  • @Nils, Ok, can you try to run it directly from the command line. You'll find the script that launches it in:


    Please post the results

  • @abilio second time ;-) i already tried to remove it complety and reinstalled it once again. the command line is my best friend :-)

  • @Nils, first time you install it in this computer? How used are you to the command line?

  • @abilio thanks - i moved it to the applications folder

  • @Nils, this will sound as a silly question, but did you drag and drop it to the Applications directory or you're starting it directly from the dmg?
