Any plans for AFPS support? :)

It's been a few years since I upgraded my mac, and don't use this anymore. I don't know what's required to support AFPS.

I'd be happy to accept a PR.

I upgraded to a new macbook without a cd drive, so I don't have a second hard drive anymore. Are you using AFPS?

Do you mean the install script? Or is it the unlock commands?

That's probably because of my horrible bash scripting. Can you give the output of

diskutil cs info `mount | grep " / " | cut -d " " -f 1`

This is just one of the commands the installer runs, I'm trying to figure out what changed in the text we try to parse.

Apfs has changed a lot.

diskutil cs info `mount | grep " / " | cut -d " " -f 1`
/dev/disk1s1 is not a CoreStorage disk

diskutil apfs
Usage:  diskutil [quiet] ap[fs] <verb> <options>
        where <verb> is as follows:

     list                (Show status of all current APFS Containers)
     convert             (Nondestructively convert from HFS to APFS)
     create              (Create a new APFS Container with one APFS Volume)
     createContainer     (Create a new empty APFS Container)
     deleteContainer     (Delete an APFS Container and reformat disks to HFS)
     resizeContainer     (Resize an APFS Container and its disk space usage)
     addVolume           (Export a new APFS Volume from an APFS Container)
     deleteVolume        (Remove an APFS Volume from its APFS Container)
     eraseVolume         (Erase contents of, but keep, an APFS Volume)
     changeVolumeRole    (Change the Role metadata bits of an APFS Volume)
     unlockVolume        (Unlock an encrypted APFS Volume which is locked)
     lockVolume          (Lock an encrypted APFS Volume (diskutil unmount))
     listCryptoUsers     (List cryptographic users of encrypted APFS Volume)
     changePassphrase    (Change the passphrase of a cryptographic user)
     setPassphraseHint   (Set or clear passphrase hint of a cryptographic user)
     encryptVolume       (Start async encryption of an unencrypted APFS Volume)
     decryptVolume       (Start async decryption of an encrypted APFS Volume)
     updatePreboot       (Update the APFS Volume's related APFS Preboot Volume)

diskutil apfs <verb> with no options will provide help on that verb

Hi,

I've made some modifications to the code that should allow this to work with APFS. It works when I run from terminal EXCEPT I'm asked to re-authorize halfway through execution and it doesn't work at all during startup (password is not found). I think it's an Apple issue in the SecItem calls as discussed here ...

https://forums.developer.apple.com/thread/88888
https://forums.developer.apple.com/thread/87095

So, it seems to be blocked until Apple fix this. I'm on 10.13.2 Beta (17C60c) btw, and can't validate against other versions.

@Taffjones That sounds very good. :-) Can you publish your changes?

Ok, but the install script isn’t updated yet (I modified the keychain entry manually) and the Apple bug is a blocker... I’ll have some time to work a bit more on Monday.

Simon

tldr;

For the record, the unlock command is the same for both file systems except one has apfs and the other has cs in the middle. My logic is to store the fs type in the comment field of the keychain entry so the couple of lines of code I’ve added to the executable can plug it into the right part of the command.

Looks like I don't have push access (probably a good thing to be honest)!

I've attached the files I've changed in this zip - @jridgewell maybe you can incorporate them for me.

NOTE - This still needs the Apple keychain bug fix before it'll work

In case this helps anyone, my fork of Unlock supports APFS. Keep in mind that I haven't tested it yet as well as I would like and that you need to install Python 3.

I don't mean to hijack the thread, but for APFS I created a pure bash-based solution to unlock encrypted volumes at startup, see https://github.com/openwall-com-au/BootUnlock (the project can create a package even without any development tools installed, or you can use the released package over there) :)

Absolutely great job @jridgewell for CS and @galaxy4public for APFS. Just moved my home folder to an SD Card and was struggling with this lack of MacOS feature. Just thank you!
