How to Fix iMessage

[Brandino]

Interesting finding. But why does changing the MLB and ROM from a real mac work? I used MLB and ROM from an air, and it worked on my imac system definition (everything but the mlb and rom remained generated by clover configurator). Shouldn't that have not worked if the MLB needs to be a certain length depending on the system definition?

This is a good point. Yes, we've heard everyone repeatedly say it's a bad idea. MLBs may be generated algorithmically according to hardware somehow, but iMessage doesn't seem to care whether they match the current hardware doing the executing.

This might be stating the obvious, but it looks like we only need to be concerned specifically with what makes the real MLBs valid. Maybe that involves reversing the algorithm, but maybe it doesn't. Should we try replacing pieces of previously working synthetic MLBs with pieces of real MLBs, one byte at a time? If so which ones? The 2nd to last digits being 1's and A's in real MLBs might be a trail to follow. Or just coincidence...

Unfortunately I don't have a real Mac to check this, but with an algorithmically generated key it's unlikely they would omit some sort of check digit. Anyone checked simple parity algorithms against the first 16 digits to see if it produces the 17th? 17 is a strange number to use, but 16 + 1 isn't.... Considering the characters appear to all be hexadecimal digits I would assume the 17th would be a check digit. Perhaps this could help generate valid MLBs?

I realise this is massively broad and their check algorithm could not only be absolutely anything, but it could indeed be server side so couldn't even be reversed out of frameworks.

after a long think over couple of days I've decided to wipe OS X off all of my hackintoshes and sell them with no OS on eBay and buy myself a official mac

So you give up only because you can't use imessage and FaceTime? why u don't buy an iPod touch or iPhone just for that.

I woke up this morning logged out of iMessage
Never happened to me before so I assume they logged me out. Is that possible?

Anyone else have this problem?

EDIT: Before anyone asks.... I am getting the customer code error now.

i have got a iPhone i got the iPhone 6 plus 128GB but thats not the point! i like to use continuity which will only work if u have iMessage and FaceTime also my family and friends have macs and iPhones etc i don't like using FaceTime on my iPhone i prefer to use it on mac also like to have iMessage saves me picking up my phone when I'm on my mac basically

Yep, same happened to me.

dravon i had this issue and ever since that happened in Yosemite i could never get iMessage working or FaceTime so I've given up with it tbh

But Jay, they are going to sort it out. It's only temporary. If you want to get a Mac so you can be problem free then I understand. Remember that it will be much slower than what you have now. Unless you get the new Mac Pro

demonknight9 i think apples tightening up on this now tbh! my iMessage will no longer work it works fine on my macbook tho so

I'm getting the mac mini for now until i can afford a iMac or a mac pro but all i need it for is music and movies and browsing really i don't think i need a i7 lol and for the iMessage it will just work with no issues
