From the front end, for supporters, yes, Sphere is compatible with Macs.

However, from the back-end, using the Sphere tools, Sphere is not compatible with Macs, and we are not able to provide support for them at this time. We suggest using a Windows emulator so you may access Sphere through Internet Explorer, our supported browser, successfully.

Below are links to Third Party websites, which are not monitored or supported by Blackbaud, however they may provide more information in regards to using an Emulator.

What is an emulator?

One option for an emulator.
