actually yeah. i just noticed the OP too. some of the information in the OP is wrong. 
please delete the section about turning coin control features on in order to use SuperSend. i fixed it in version 4.0.0 that you no longer need to do this. you can select to use supersend to send anonymously regardless of coin control features being on or off
the 4.0.0 wallets have about 100k more blocks before they will no longer function and will fork. so we will just need to find someone to compile a mac wallet before then. 
Is there an exact block number for the switchover?
changes over at block 3,153,600
@Fuze - Can we have the info about this new change on the OP? (list of changes etc)
Also, can we have a better categorized & simpler OP? It's quite confusing right now IMO.
e.g. 
https://bt.irlbtc.com/view/1262920.0https://bt.irlbtc.com/view/616792.0Coin control page has been removed.   I have also added the block that all Supercoin wallets must be updated by.
I will start working on organizing the original post.  Casinocoin bitcointalk is what I am leaning towards.  If anyone would like to organize the info please send me a PM.
