Can I run Simul8 on my Mac?

Anonymous (anonymous@undisclosed.example.com) — 2025-10-23T11:23:36+00:00

Can I run Simul8 on my Mac? We frequently get asked if you can run Simul8 on an Apple Mac instead of a PC and the answer is yes - in fact many of our employees work on Macs every day. Mac users can use Simul8 for the web to build, run and share simulations in a browser with the same full feature set as our desktop application. Depending on your OSX version, you can also use virtualization software, like VMware Fusion or Parallels, to run Simul8 for desktop on Mac.

My simulation won't load

Anonymous (anonymous@undisclosed.example.com) — 2025-02-12T09:39:50+00:00

My simulation won't load If your simulation file is very large, Simul8 might take a while to load it. This often occurs when: Saving the simulation without resetting Information carried on Work Items often takes up a lot of memory, particularly if you have many Work Items. When saving without resetting, the Work Items together with the information they carry are left in the simulation, and when Simul8 is loading the simulation, it is trying to load all this information as well.
