I am using time machine backup as a double protection other than iCloud. Are the above warnings will affect my data integrity in the future ? If so what should I do to get rid all of those warnings.
I can still use my M1 Macbook Air without any issues so far. But I worry this warnings will create further damage in the future.
Thank you guys.
