License Use

Last updated: August 5, 2026

One purchased Fibich license covers one Mac at a time. A separate license is required for each additional Mac.

These rules apply to Fibich licenses purchased on or after August 5, 2026. They explain how a perpetual Fibich license may be installed, used, reinstalled, and moved between Macs.

One license covers one Mac

One purchased license permits Fibich to be installed and used on one Mac at a time. A separate license must be purchased for every additional Mac on which Fibich is installed or used.

The count is based on Macs, not on application files or macOS user accounts. Replacing one copy of Fibich with another copy on the same Mac does not require another license.

Reinstalling on the same Mac

You may reinstall Fibich and reactivate the same license on the same Mac without buying another license. Keep the purchase email and license key in a safe place.

Moving a license to another Mac

You may move a license to a replacement or different Mac. Before activating it there, remove the license from the previous Mac or stop using Fibich on that Mac. You may move the license again later, but only one Mac may be covered at a time. If the previous Mac is lost, damaged, or inaccessible, you may use the license on its replacement; if the old Mac becomes usable again, stop using Fibich there unless you move the license back.

Using Fibich on more than one Mac

If you want to keep or use Fibich on two Macs—for example, a desktop Mac and a MacBook—each Mac requires its own purchased license.

Perpetual and offline

A Fibich license is perpetual and does not expire. Fibich validates the license locally on your Mac and does not require an ongoing internet connection after activation. “Perpetual” describes how long the license lasts; it does not expand the license to additional Macs.

Questions

If you are unsure whether you need another license, contact the Fibich website operator before purchasing.
