Mac OS 10.7.5 or better using an Intel-based processor (all systems built in the last 4 years)

Note: if you have a Macbook Air made in 2011 using the HD3000 Integrated graphics card, you will need to upgrade to 10.8.3+ to correct an Apple graphics driver problem which creates distorted characters in the simulator. You can upgrade using AppStore.

Alternatively you can use our program on any of the wide array of compatible Apple and Windows computers (Vista-Windows 10)
