    How to Fix iMessage


    Made a fresh install and did as Jaymonkey wrote in post#383

    "Please ensure that the key value you set in your plist is called "SystemId" not "SystemID" or other permutation.

    Use a random UUID as the value for SystemId not one of your existing UUID's, this will ensure that the newly generated platformUUID will be unique.

    Delete the existing nvram.xxxxx.plist in /Extra.

    make sure you have FileNVRAM version 1.1.2 installed

    Reboot and try again"

    And that worked

    I can confirm that this worked for me as well. Just had to use me @me.com version of my apple ID and not my @gmail.com. No password change needed.

    I actually solved it.

    I replaced nvram 1.1.3 with 1.1.2 and changed UseKernelCache to No in my plist. Rebooted and the next time I tried to log in I got the error with the customer code (previously it was giving me activation error). Then I just went on apple support and they resolved the issue for me, I just had to give them my Apple ID, he said it was something to do with my serial number. They probably knew I was on hack anyway.

    How to Fix iMessage


    @Jaymonkey

    In post#383 you wrote:



    “The platform UUID and hardware UUID should always be the same”


    But thatīs not the case on my UP5-TH.


    When i use ioreg -lw0 | grep PlatformUUID in terminal i get the same values as i have in system profiler Hardware-uuid that are not equal to the values i have in org.chameleon.boot.plist/ equal to what ioreg.app shows.


    I donīt know if itīs important as iMessage is working

    I added the
    <key>SystemId</key>
    <string>blablablamyID</string>
    into /Extra/org.chameleon.Boot.plist

    Then rebooted.
    iCloud and several mail accounts asked me to enter password.

    Now: PlatformUUID == Hardware-UUID != SystemId

    iMessage is NOT working again of course.

    My hardware: ASUS P8Z77-i + i5-3570k
    FileNVRAM.dylib is version 1.1.2

    EDIT: Like Klorin wrote, I had to change my password on "http://appleid.apple.com", reboot and then login to iCloud (and iMessage) again and everything works. Not sure if I'd have to do the SystemId stuff before...
    Thanks Cyb3rfr3ak, your idea of changing the password is what worked for me. After using a randomly generated UUID, and placing in Chameleon as SystemId, still didn't help. After changing the password on http://appleid.apple.com, then rebooting, it's all working now.

    make sure that you do not have SystemId being defined in your chameleon.plist and reboot (might need cold boot ?)

    open ioregistryexplorer and check the following location :-

    IODeviceTree : efi / platform / system-id

    Attachment 89503On all my systems there are 16 x 16 bit values all different

    Theory:-

    If this location contains all zeros then setting SystemId in the chameleon.plist fixes your issue.

    If this location already contains 16 seemingly random numbers then setting SystemId does not fix your iMessage problem, in which case we've only solved half the puzzle ?

    Would like feedback on the above to prove or disprove.

    If it is still not working, try the following:-

    @All

    To those of you that it hasn't worked for :-

    • Please ensure that the key value you set in your plist is called "SystemId" not "SystemID" or other permutation.
    • Use a random UUID as the value for SystemId not one of your existing UUID's, this will ensure that the newly generated platformUUID will be unique.
    • Delete the existing nvram.xxxxx.plist in /Extra.
    • make sure you have FileNVRAM version 1.1.2 installed
    • Reboot and try again

    If iMessage is working for you now ... does the value in the IOReg at location :-

    IODeviceTree : efi / platform / system-id -> (see above post to @wolfie81)

    .... match the value you set the key "SystemId" in the chameleon.plist ?


    • The platform UUID and hardware UUID should always be the same
    • SystemId should always be unique and will always be different to the platform & hardware UUID


    Cheers
    Jay


    ive done your test, it shows this in iodevicetree
    "00020003-0004-0005-0006-000700080009"

    that's the default UUID nvram uses as placeholder.

    while my platform and hardware UUID is 55ADE930-5FDF-5EC4-8429-15640684C489

    which is another default one.

    not working for me still! =\ i even changed my apple pw and made sure nvram is 1.1.2

    weird is i can see that bubble "typing" indicator from the receiver in imessage!

    so my problem is what i'm setting in SystemId, isn't affected by hardware/platform UUID

    @3square

    double-check that you added your SystemId correctly to org.chameleon.Boot.plist

    <key>SystemId</key>
    <string>the id from random generator here</string>

    try boot with:

    <key>UseKernelCache</key>
    <string>No</string>

    How to Fix iMessage


    Alright,

    So, here I am:

    - Fresh install
    - Multibeast
    - Random UUID generated
    - Added to chameleon plist under SystemId key

    Code:
    <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
        <key>EthernetBuiltIn</key>
        <string>Yes</string>
        <key>GraphicsEnabler</key>
            <string>Yes</string>
            <key>IGPEnabler</key>
            <string>No</string>
        <key>Kernel</key>
        <string>mach_kernel</string>
        <key>Kernel Flags</key>
            <string> PCIRootUID=1 -v</string>
        <key>Legacy Logo</key>
        <string>Yes</string>
        <key>Timeout</key>
        <string>2</string>
            <key>DropSSDT</key>
            <string>Yes</string>
            <key>GenerateCStates</key>
            <string>Yes</string>
            <key>GeneratePStates</key>
            <string>Yes</string>
            <key>UseKernelCache</key>
            <string>Yes</string>
            <key>Graphics Mode</key>
            <string>"1920x1080x32"</string>
            <key>SystemId</key>
            <string>66612940-C49D-11E3-9C1A-0800200C9A66</string>
    </dict>
    </plist>
    - no change to smbio.plist
    - Rebooted
    - Hardware UUID and Platform UUID are the same but they are different than the UUID in the chameleon boot plist (which I understand is the correct)
    - password changed for the Apple ID
    - try to login to iMessage - error that something went wrong and I should try again later.

    Keep getting the "Registration failed" message in Console.
    As well I get something about some "unrecognised leaf certificate" but i don't think is connected.

    IODeviceTree:/efi/platform: <00 00 00 00 00 00 00 00 00 00 #c #c ## #c #c #c>
    (I substituted values with # and c; #=number; c=letter)

    PS: logging in from a real Mac worked without problems. Trying to login back on my Hack did not yield success. Logging in to iCloud works. App store works.

    Working on this for few days already.
