Mac version of Simile 6.6 hangs intermittently


I am currently using Simile 6.6 to teaching ecological modelling to a class of 4th year undergraduates and MSc's.

Two students with Macs are having issues with simile hanging or unexpectedly closing. It doesn't appear to be related to any one action that they are doing. The model they are working with is simple (one compartment, a couple of flows and variables).

Do you have any other issues like this and can you suggest a fix?

Below are details of the machine for one of the students and the first lines of the error report.

All the best

We've had quite a few reports of problems with OSX 10.11. Unfortunately no-one at Simulistics has a Mac new enough to run this version of the OS. I have ordered one and will be investigating these problems as soon as it arrives.


We finally got hold of a Mac capable of running El Capitan, and have now fixed this problem. The current download of the 64-bit Mac version, v6.6p3, is stable is all versions of Mac OS X from 10.6 on.
