I enabled FileVault in 10.9, and I can't delete files from my backup. I used to use this (pre-10.9 and pre-filevault) when I had big files in downloads that I wanted to destroy forever. I have some installers taking up space on my Time Machine and wondered if anyone knew of ways to remove those files. There used to be a button under the gear to delete from a given backup or from all backups. Is this still possible in some way? Thanks!
