Yesterday night I enabled FileVault in my iMac (2017), and it's still encrypting. Earlier it said it would take more than one day to finish, now it's saying 15-16 hours. diskutil in the terminal says it's at 66%... Questions: - is it normal that it is taking this long with High Sierra also on a very recent Mac? - the startup disk is a Fusion Drive. Does FileVault in HS affect in any way how Fusion Drive works / organises automatically data between the SSD and the hard drive? - does the Core i5 in the iMac have hardware support for the encryption used by FileVault? if yes, does FileVault in High Sierra affect performance anyway once the initial encryption is complete or isn't it noticeable these days with latest OS and hardware? Thanks!
