We want to make sure that we deliver a product where all functions work flawlessly. To meet this target, Acronis will put increased effort into polishing the cloning function. Additional time is required due to extensive changes in macOS 11 Big Sur architecture.
For Acronis True Image 2021 installed on macOS 11 Big Sur, disk cloning is not available for disks with macOS 11 Big Sur and macOS 10.15 Catalina. Disk cloning will be available again in the next update of Acronis True Image 2021, expected to be delivered in November 2020. This article will be updated when this update is available.
