Just a thought, but since the volume is already mounted, shouldn't the command be
?
(i.e. remount the already mounted filesystem and make it writeable.)
In theory, the u switch should do that. https://developer.apple.com/library/mac/documentat.../sbin/mount -o remount,w /
?
(i.e. remount the already mounted filesystem and make it writeable.)
I think we might be flogging a dead horse here for Scars

OK, this brings up something slightly different:/sbin/mount -o remount,w /

I don't suppose you back up your passwords and whatnot to your iCloud keychain?
Might be able to obtain the unlock key by logging into your account from another Mac.

Depends which version of filevault the drive was encrypted with.

Not really sure to be honest, I don't remember selecting it as an option. I had hoped that the Apple store guys would have advised me on my first visit after I gave them my ID etc. Might be able to obtain the unlock key by logging into your account from another Mac.

Interesting!
You don't have a disk. Would the process be the same with the recovery partition?
That option isn't even listed on the man command page Andrew! Good knowledge

It's the "normal" unix way of doing it. At least - it's worked on every version of unix that I've touched in the last 30+ years
From the response, it looks like OSX is intercepting commands to prevent whoever has physical access to the machine from doing resets.
It that situation, I'd be looking into pulling the drive, mounting it on another machine and being clever with "chroot" to change passwords (do not try this if you don't know what chroot does because there are several steps to follow after it) or an editor to wipe out the entries in the password file (do not try this if you don't know which files are involved and what their contents should look like).
The suggestion of going back to the reseller and booting from an external recovery disc sounds the most sensible at this stage.

If it's locked and you've no backup, and you've not stored your keys anywhere then it's a re-install.

Apple can't break into it, they made a press release stating that there are no back doors or any workarounds for the encryption they use on their devices.

Yep, I know that's highly likely - before reformatting though, I want to have some variations of the passphrase brute forced seeing as I have a clear idea of what the phrase is supposed to be (although I've already spent days trying this).If it's locked and you've no backup, and you've not stored your keys anywhere then it's a re-install.
In addition I'd like to hear from apple techs that it's game over, or if they can force the disk to mount or something.
I appreciate your input though, as well as the help that everyone's offered.

Here’s a somewhat specialised problem for you guys to get your heads around – let’s see if anyone can help.
I’m having trouble with the Bluetooth connection to my wireless keyboard and magic trackpad. Since setting up my Mac Mini in a media cupboard after moving house, the keyboard/trackpad signal is very poor. Cuts out, stutters, etc.
I know this could be the placement of the Mac, or could feasibly be interference from a USB3 external hard drive placed nearby. Neither of these caused issues at my old house, mind you.
Regardless, my solution is to run a USB extension cable out into the living room (taped to the underside of the TV stand) and attach a USB Bluetooth dongle to the end.
I know enough to download and use Apple’s Bluetooth Explorer app from the OS X Developer Tools to let me switch from the Mac’s internal Bluetooth to the new external one. So far so good.
But now, after making the switch, I can’t get it to pair with the keyboard and trackpad. Not at all.
Any ideas? Could it be that the new Bluetooth dongle is only Bluetooth 2.0 spec? Should I buy a 4.0 one instead and try that?

It’s a cheap one from Maplin. Supports BT 2.0.
I’m wondering whether trying a Belkin BT 4.0 dongle would make a difference.
The keyboards are BT2.0 but a 4.0 adaptor will work with it. I’m wondering whether trying a Belkin BT 4.0 dongle would make a difference.
Maybe your extension lead is affecting the power going to the dongle, does it work OK if you don't use it and just try direct?
I’m getting nowhere with the Bluetooth thing, unfortunately.
Tried a different (Bluetooth 4.0) USB dongle. Tried both dongles connected directly to the Mac. Tried them both on a USB extension. I can’t get either of them to pair with the keyboard and trackpad.
Unplug the dongle and the Mac switches back to its internal Bluetooth chip and immediately recognises the keyboard and trackpad. But the signal is too weak and control is poor.
Very frustrating!
