How to confirm FileVault encryption has fully completed? While it's in progress, diskutil apfs list | grep 'Encryption Progress' ; fdesetup status will shows percentage of conversion.

Later is there any way to know 100% encryption is completed?

    I was about to flag this question as a duplicate of apple.stackexchange.com/q/60683/45492 but noticed that diskutil apfs list does not mention encryption status (anymore?). Is that a recent change? diskutil cs list works as expected for non-APFS volumes. – n1000 May 7 at 6:40

APFS volumes

It seems that the only way to tell for APFS volumes is to use fdesetup status. This fantastic blog offers a script which basically uses that command to determine the status. In the article it reads:

If encrypted, the following message is displayed:

FileVault is On.

If not encrypted, the following message is displayed:

FileVault is Off.

These are basically the outputs of fdesetup status.

Non-APFS volumes

For non-APFS volumes there is more information. Try diskutil cs list or diskutil cs list | grep "Conversion Status", respectively and look for Conversion Status. See also the accepted answer here.

$ diskutil cs list
