Mac Installation Issues with old OSX

[shamil]

Thanks for all the amazing work you do!! Awesome that LB is OS independent now!

Unfortunately it seems like my installation wasn’t successful, with the message below (same message for all libraries…). I’m running Rhino 6 on High Sierra, OS 10.13.6. Is my OS version too old?

I also tried installing Python3 separately and verified it was successfully installed but no luck with LB Tools still.

Thanks!

Hey @shamil ,

See here:

Unable to install Ladybug Tools 1.0.0 on Rhino6 Mac

Hi @mostapha thanks for the response, Below are the contents of the error messages: {0;0} Installing Ladybug Tools core Python libraries. Installing lbt-dragonfly[cli]==0.5.1 via pip using /Users/narz/ladybug_tools/python/bin/python3 dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin Referenced from: /Users/narz/ladybug_tools/python/bin/python3 (which was built for Mac OS X 10.15) Expected in: /usr/lib/libSystem.B.dylib dyld: Symbol not found: ____chkstk_darwin …

You have an old version of Mac OS installed that’s incompatible with the Python package that Ladybug Tools uses. Once you upgrade your Mac OS, you should have no issues installing.

Ok! Thanks for the reply @chris. Well, my 2011 MBP’s days are numbered anyways alas

I can also confirm that Ladybug is functioning well on MacOS X 10.14 Mojave. I have so far tested HourlyPlot, Sunpath, DirectSunHours, SkyMatrix, IncidentRadiation, WindRose and LegengPar. It also takes the legacy (Ladybug 0.0.69) components I built on Windows including reColorMesh, northArrow and legendPar.

Ah, yes. I had one of those from right before they switched to the quad-core CPU architecture. I remember that I couldn’t update the OS at a certain point because of that. 9 years is probably pushing the limits of the design life.

And thanks for confirming, @wwkid . That’s good to know that the OS doesn’t need to be the absolute latest version.
