Check out the call customer support section of this guide. jaymonkey recently added a part about WAN IP bans for a specific Apple ID if two many devices come from it.
I went to icloud dot com and looked under settings and my main I.D. has about 5 different Mac's listed under devices LOL.
Same thing happened to me !
@Guys,
The issue on unknowingly creating multiple (invalid) identities for your hack(s) has been covered in the guide for a long time, It first became a problem about three years ago when non persistent ROM values were automatically generated by legacy boot loaders such as Chimera on each boot, (when iMessage first launched that was not an issue). As stated in the guide in
multiple places, when debugging iMessage issues on a Hackingtosh I always recommend to keep the machine off-line or quarantined on your network until your happy that all ID's are correct and persistent, only then connect to iCloud services.
The problem now is that you have multiple devices associated with your Apple ID that are either invalid and/or no longer accessible to log them out - these will not expire like a iMessage security token. It is also possible that these devices may be causing a device miss-match on Apples system if one or more of the devices has a common ID with another .... I've never been 100% certain about this nor the number of times a miss-match can be logged against a AppleID but it sounds like you guys are in this situation and that the number of miss-matches is five, Once this lockout is in-place you can no longer associate any new OS X devices with your AppleID.
You could try contacting Apple support and ask if its possible for them to reset/remove the devices against your AppleID .... but I've never tried that so I'm not sure what the outcome would be, if any of you guys do try this approach please post feedback on how you get on.
The only way to log them out and diss-associate them would be to recreate the device identity for each one but this is only possible if you know ALL of the ID's for each device (SmUUID, OS X S/N, ROM, MLB) ... this is only possible if you have a backup of each devices Identity. This is why i recommend (in multiple places) to always keep and re-use working ID's for the life of that system.
Your only other alternative is to Create a new AppleID .... disconnect all machines from your network (logout of all iCloud services first !!) and create new identities for all of your hacks, once the ID's look good reconnect and re-associate them with your new AppleID. If you don't have any purchases against your old AppleID then you could then try deleting it ... however this will not be an option if you have a lot of app or itunes purchases against your account. Unfortunately Apple do not allow the transfer of purchases between accounts so you'll have to keep the old Account alive even if you don't use it anymore.
Remember this would never happen using genuine Mac's as all ID's are burnt into the system board and are always persistent ... so don't blame Apple ..
Cheers
Jay
