Sorry if I posted this on wrong section, but I trying to change my system-id to get imessage working, and I found out that there is an option called "SystemId" for org.chameleon.boot.plist, to change the system id manually.
My system id now: 0000000000000000000000XXXXXXXXXX (XXXXXXXXX = my MAC address)
This looks odd with the many zeros, I thought that maybe this is the problem and this is the reason why imessage doesn't working for me.
I tried to make a "SystemId" key into my org.chameleon.boot.plist file and generated an own uuid and set that up, but my system-id stays the same with the zeros. It just ignores this setting...
I also tried "SMsystemid" in smbios.plist, but it's ignored too.
Anyone knows how to change the system-id value? Is it possible?
(I'm using chameleon 2181)
Edit: I changed the org.chameleon.boot.plist > "SystemId" from Windows (macdrive), and since then, I can change my systemid to anything. (from osx too)
