While we have been testing Photo Mechanic 6 and Photo Mechanic Plus on macOS Big Sur, we have not announced that it is a compatible operating system for use with our software yet. We generally suggest that our customers wait for at least three updates and back up their hard drives before upgrading to any new macOS.
Although Photo Mechanic has not been completely tested on Big Sur and M1 Macs, many of our customers have been using Photo Mechanic on Big Sur without reported issues. We will continue to test compatibility and work to ensure that we are compatible with both Big Sur and M1 Macs.
Please check the notes in each future build announcement to see if we have verified Photo Mechanic compatibility for macOS Big Sur.
