ref dlrpgmsvc : both partitioning programmes cited are Windows, can anyone recommend  a similar one for Mac?

ok, I can see that with deleting on the Mac. Deleting in camera from either filemanager or from playback using the trash button, the space is not released until the camera is turned off and then on. Could there be an option for delete to release the space when deleting on camera,  without having to Off/ON? I aim to shoot drama and be able to quickly trash false starts bad takes etc Thanks.

Can't find an answer to this: when deleting raw files from  the card, either in camera or on a mac, the card seems to retain hidden files? These are hidden in both camera file manager and Mac Finder. The space is only released when the card is formated in camera. How can I delete files on camera and free up the space without deleting all the files by formatting? Is this a general issue with other cameras?

If at first.........tried it a third time and this time it's worked, I have the green screen:)
Enough for today. Thanks.

Macboot not eoscard
I have all the other files on the card - just 550D not the other cameras.

I don't seem to be able to make SD card bootable. Eoscard says :
Suitable cards present: 1
scripts=false chdkboot=false chdk32boot=false dslrboot=true
Command 'diskutil unmountDisk disk1' = '!Error
Unmount of disk1 failed: at least one volume could not be unmounted'
   return code was 1
making DLSR-bootable - format=2
making FAT32 DSLR-bootable
Command 'printf "EOS_DEVELOP" | dd bs=1 count=11 seek=0x47 conv=notrunc of=/dev/disk1s1' = '!Error

dd: /dev/disk1s1: Resource busy'
   return code was 1
Command 'diskutil mountDisk disk1' = 'Volume(s) mounted successfully'
   return code was 0

When I put the card in the camera, it doesn't seem any different than usual. Pressing trash has no effect.

Through a glass darkly! ok I'll try the first install of the stable 2.3.
So is the RED warning in the original post now redundant?

Sorry still not clear. 
on a 550D with unknown history, before I start installing ML,  how do I check the status of the camera bootflag, so I can decide to first or second install?  as per the install instructions. I'm trying to avoid the camera "getting stuck" - is that the same as "bricking"?  Thanks.

"If cam gets stuck" then remove card and battery? then second install nightly or 2.3?
"or ML loads" second install latest nightly?

re --The First Install (first-time installation - for a camera that has never had ML on it)

This process should only be performed once (for each camera, if you have used ML before on the camera you are using then jump below to "The Second Install".).

I'm a newbie, can't find an answer to this:
I have just got a second-hand 550D and don't know it's history, it is in good nick and works well. Before I start installing ML,  how do I check the status of the camera bootflag, so I can decide to first or second install? Many thianks, great work!
