Och nu säger även Eventide samma sak:
Please Wait to Update to macOS 11 Big Sur
Today, Apple released the new macOS 11 Big Sur. We have been testing macOS compatibility throughout the Big Sur beta program, and at the moment are not yet fully compatible. While we expect to be fully compatible soon, we recommend waiting to upgrade to macOS Big Sur if you are using Eventide plugins.
Visit our Big Sur forum thread regularly to obtain up-to-date information on macOS 11 support.
Thank you,
Your friends at Eventide
