Hi everyone, I've been having a ton of problems with time machine since updating to 10.12, but today has been the worst. I plugged the drive in, and it gave me a warning about the disk being unencrypted. I tried to go into settings to see if it wanted me to change it, and I'm pretty sure it deleted all of my previous backups. Before, when I'd backup, it always told me when my oldest backup of this drive was. Now, it's gone. When I go into Time Machine by actually clicking the TM logo, it does take me "back through time" where I can see stuff from previous months, but I don't think my MacBook recognizes it anymore. Is there a way to check if I still have my backups? Is there something in particular that I can look for? Thanks, I've never had this happen before, so any help is appreciated.
