How to Fix iMessage

This Apple Mac Hack tool seems to be far from the solution of the iMessage problem. But if it actually extracts the correct Board and ROM info from the system, it could be useful for deciphering how the MLB and ROM values are written, which could then lead to an actual solution.
 
Is there a way to generate MLB from Apple MAC Hack yet? Or do you only need the 3 values it can currently generate ... suUUID, ROM / MAC address, and custom UUID? The MLB / SN are extracted from the system itself and aren't generated when I click the generate button ...
 
Hello guys,

I took a look at Apple MAC hack and I didn't catch up how it could help us to solve the issue between pair of MB Serial Number and SMUUID.

Anyway, jay monkey - do you have any news for us?

Thanks
 
Apple MAC Hack doesn't do anything to help us. It's still copying MLBs and ROMs from real machines, which is exactly what we're trying to not do.

Just wanted to share my experience fixing iMessage and FaceTime. Previously, only FaceTime worked but iMessage didn't. I was running Yosemite on a Z77X-UD5H 3770K with Chimera. I updated to Clover using a few guides I found on here, fixing sound by using toleda's Clover patch. I generated a new serial in Clover Configurator, a 11 S/N. I added to numbers to this serial and pasted it in MLB (RT vars tab) and Board Serial Number (SMBIOS tab). I used the terminal command 'uuidgen' a few times and pasted the last output in smUUID. The part after the last '-' (dash) was pasted in ROM in the RT variables tab. About this time iMessage gave me the code to call Apple. I rebooted a few times, making sure my NVRAM worked by checking iMessageDebugv2's output everytime I rebooted (save output, rename output, reboot, save output again, check if they're the same, they should be). I called Apple, gave them the serial of my (real) MacBook Pro. I logged out on iMessage on the MacBook also, and when they entered the code I logged in with both machines at the same time. Both machines (hack and MBP) work now. Hope this helps some of you out.

Just to be clear, this worked with GENERATED MLB and ROM values.
 
@hylkepykle when? If this was shortly before about the 17 November, you will probably find you will shortly be logged out and be stuck in the same position as everybody else.

If it was after, then thats interesting and we need to figure out why it worked for you.

It is using a Z77X-UD5H 3770K and normally should be configured as iMac13,1/2 or MacMini6,2, but he generate an 13 character MLB, how an old MacPro. Since I managed to solve the issue only on the old MacPro3,1 hack, loggin straight in iMessage and Facetime without the need to call Apple support, I'm thinking that maybe it is easier to circumvent controls using 13 characters MLB.

@All

@flicka's thoughts are correct in that earlier (~ pre 2010/2011) systems such as MacPro 3,1 that have a 11 digit OSX S/N only have a 13 digit MLB not 17 digits like later (Generation 2+) Apple models. The 13 digit MLB patten is a much simpler format/syntax to the 17 digit MLB's and thus i do not believe that they can be processed by the new Apple iMessage MLB authentication process - they simply do not contain the checksum/lookup/reference values needed.

So systems configured with 11 digit S/N & 13 digit MLB currentley still work with iMessage as long as the MLB (and ROM ?) is registered with Apple. However you should all be aware that more recent PC hardware should ideally use a later (> 2011) system definition such as iMac 13,1, 14,1 ... etc in order for many of the newer OSX features introduced in Mavericks and Yosemite to work correctly.

Work is continuing on understanding and deciphering the 17 digit MLB patten and it should only be a matter of time before a method for generating valid 17 digit MLB's is found and implemented in Clover Configurator and Chameleon Wizard.

Good things come-to those who wait ... be patient and keep an eye on the guide/this thread.

I've updated the news in Part-1 of the guide with the current iMessage status and details of an updated version of FileNVRAM for those for you using Chameleon.

Apple-Mac-Hack Utility

I've taken a quick look at the Apple-Mac-Hack utility thats been mentioned recently and it does not do anything we cant do manually and already detailed in the guide.

You could think of it as a GUI based version of iMessage-Debug mixed with the ID generator from Clover Configurator. It's meant to be run on a real Mac and will extract the MLB value and generate a matching set of unique UUID's and (optionally) a ROM value which you can use to configure a hackingtosh.

This method has already been discussed in length and you should all know by now what the majority of people think about these methods ....

The only real interesting part (IMO) is the apparent ability to generate a random Apple ROM Value, if this proves to be true then it could be useful if and when it is confirmed that the new iMessage authentication checks are validating the ROM value - currently this is still un-confirmed.

Cheers
Jay
 
I'm using a 13 character MLB (not 17) in conjunction with a 12 character SN with no apparent problem.

So does this mean that if the MLB/ROM passes authentication then the SN does not matter.
