Can Mac users fill out the form?

I have created several forms and used them for months now without any problems.

Yesterday someone using a Mac emailed me and said they were not able to fill out the form on their computer.

Are mac users able to fill out the form? I don't have a mac to test it on.

Thank you,

Lisa

Yes, the forms are compatible in any browser and operating system. Did he receive an error? What is the form, and the Mac and browser version he was he using? Please let us know, so we can test further.
