"To improve reliability, Time Machine must create a new backup for you."
Had the dreaded "Time Machine completed a verification of your backups...To improve reliability, Time Machine must create a new backup for you" message.
I have spent several days clicking "Back Up Later" in the hope it fixes itself or I find a fix on this site, but currently no luck with any of the suggestions. Has anyone had any luck with fixing this issue at all? I am using TM on an iMac running High Sierra (10.13.3) and using an Airport Time Capsule. Would creating a wired connection between Mac and TC make the problem go away, or would I still have to erase all previous backups to move forward?
