Click to expand. A 500 Gb (300GB used) High Sierra APFS volume took 6 hours which is about what I am used to on earlier OSes. I just turned on FV on 50GB (20 GB used) HS APFS volume and it says 14 hours.
I will report back when it completes. My guess it will be a lot quicker. The estimated time varies wildly. Running diskutil apfs list in Terminal will show what the actual percentage encryption status is rather than the unreliable time remaining.
The Terminal window doesnt update, you need to relaunch it from time to time. PS.the above is different from what you have quoted below, because when I tried to add the bit about Terminal I managed to delete my original reply, so re-wrote it! I turned on Filevault on a 500Gb (300 Gb used) HS APFS volume and it took 6 hours. The estimated time varied wildly, but that is what it took. This is typical of what I have seen with earlier OSes.
Maybe your 20 minutes on Sierra was with a nearly empty drive? Although I am not quite sure whether the amount of data on the drive is relevant or not.I think not.
I just turned FV on a small 50Gb HS APFS partition with 20 GB used and it says 14 hours remaining at this moment. I will post back when it is done. My expectation is that your 10hrs and my 14hrs will actually be a lot less. Click to expand.As soon as I do a clean install, before installing any application the first thing that I do is to turn on FileVault, that could be the reason for the 20 minutes that it takes to encrypt a 250GB on macOS Sierra.
This time I did the same with macOs High Sierra, turn on FileVault without installing any applications and it shows 10 hours to encrypt. Very unusual, but it seems that I'm not the only one. It has pass about 1 hour and the blue incremental bar show that 40% is done, it could be as you say, it my take less than 10 hours. Thanks for your answer.

Hi, What i seriously do not understand: - If encryption is already part of APFS, why are we still able to (un)select FileVault then? - When we accidently select/activate FileVault, it takes hours and hours and hours to encrypt (+ afterwards optimize) (while the encryption is already part of the new format APFS) (so why is this taking so long)?? I have 500GB SSD and it is already running for 16 hours and keeps running.
Also started this on my Macbook Air, there it took 6 hours (also 500GB) and is now optimising (also for a few hours). Something does not look logical to me with the new APFS + encryption vs.
Is this an error in the flow? Indeed, the encryption was taking like 4-5 days & nights. And was not even ready yet: first the 'Encryption process' that takes place (which already took 4-5 days), next is the 'Optimisation process' (also taking serious time) (tested this on my Macbook Air where it was little faster) (both have 500GB sad's, so don't understand where the difference comes from, both quad core Mac's). Also decided also to go back to completely reinstall Sierra and leave High Sierra, too many (and serious) issues with High Sierra (crashes on apps, logging-in with bluetooth keyboard & mouse not possible, cannot pdf-print documents anymore, cfr. Sudden message 'filenames cannot be longer then 31 characters', etc, etc, etc). High Sierra is in my opinion not ready for release.
(or you have to be very lucky on the install and having no issues. I presume or possibly depending on kind of usage of Mac's (personal or professional/intensive use). Click to expand.Sort of.
How Long Does File Vault Encryption Take
The end result encryption would be the same, but if you format to APFS encrypted then do an install the boot process will not work properly. When you just format and install, then afterward turn in FV, it does more than just convert the drive to APFS encrypted. It also changes the boot process so the system boots to the recovery partition then propts you for a password to 'unlock' the encrypted drive. If you format to encrypted first, then install, it does not do this boot process reconfiguration and does not boot like it should. So bottom line is, no you do not want to format to encrypted then install.
