I have upgraded to 2020 iMac. Time Machine came over in Migration and at first use allowed me to Inherit Backup from previous machine (2015 iMac on Catalina). When I run TM I can see older backups on the right hand bar but they are all a lighter red shade. Clicking on them does not access the ™ backup. Backups made on new iMac with ™ working normally.
Any suggestions on changes to allow access?
