What does "designed and developed for macOS" mean?

Microsoft has launched its Office applications including Excel for macOS some years ago. Unfortunately, the calculation speed and functionality of macOS versions lack far behind the Windows applications. Calculations take several times longer and many features of the Windows versions are implemented on macOS either not properly or not at all. We therefore have developed the add-in specifically to run on macOS devices and considered all restrictions of the macOS Excel environment. As Windows versions are more mature developed, there should not be any problems in running the add-in on Windows devices due to upward compatibility.

Are updates free?

Yes, all updates for the current version are free during an active license period.

Do I need a working Internet connection to run the add-in?

Do I need an Internet connection for activation and deactivation of a license?
