Time Capsule greyed out when trying to upgrade Mohave to Big Sur
Updated Mojave to Big Sur on Thursday and have spent DAYS trying to get files migrated to MacBook Air. Backups are on Time Capsule. Entire system was backed up prior to the update. I can see the last backup. When I click on it, however, it goes through the motions of loading and then suddenly greys out and stops. Suggestions on getting access to that backup?
