Cura stopped working for mac

Hi All,

New to the forums, new to 3D printing. I'd been using Robo's Cura 2.3.1 for my C2 with no issues until I updated macOS to 10.12.4. Now it constantly freezes up and eventually causes the computer to crash. Anyone else having issues?

 

Thanks, I'm trying to install Cura 2.5 but when I open it, nothing happens.

(I also just realized I posted this in the wrong place on the forums, oops)

 

I'm slicing on a MacBook Pro w/4GB memory, OS X El Capitan v10.11.6 and Cura 2.3.1. Seems to work fine but I haven't upgraded to Sierra (10.12), for what it's worth. (Thanks for the warning.)

Nilrog here suggested that it has something to do with where the settings are stored: ~/Library/Application Support/cura (looks like root access would be required for updates) versus ~/.cura (your user would have rights here). So maybe 10.12 has tighter enforcement of not-writing-to-global-areas or something. Same thread mentioned, Gnevko indicates that he deleted the app, emptied the trash and re-installed Cura again to make it work. Another user confirmed same. (Again, the settings folder rights idea could explain both fixes.) Same thread, someone else created a new app in applications and then dragged all the Cura stuff into it, which worked.

The particular error seen in some of their crash dumps looks like "software with a bad pointer in it" = buggy code.
