ArrangeMyWorld is designed for Microsoft Windows and does not operate on MacOSX 
.
We regularly receive enquiries from Mac users and we do have several customers that have successfully installed the product on Macs running Windows in parallel or natively. However we do not provide technical support for these installations.
We hope to commence work on a Mac version of ArrangeMyWorld soon.
If you would like us to advise you when the Mac version becomes available, please send us an email to info@arrangemyworld.com
Thank you for your interest,
Product Development Team
