2017 MacBook Pro, OS 10.13.6
Last year I encrypted my Time Machine external HD because it was going to be mailed and put in storage. When I got it back, I found Time Machine did not work (entering Time Machine revealed there were no backups indicated on the timeline, and there had been many). An Apple Support search confirmed that an encrypted HD cannot be used for Time Machine backups.
My question: can the Time Machine function (with items saved before the encryption) be restored by un-encrypting the HD?
