iMessage poll
same problem here. started about the same time as everyone else
I have a fix that work for me on 2 hack.... after this fix all is normal EXCEPT that the computer name disappear in finder, it seem to be just cosmetic...
HERE IS WHAT I DO:
Download the "Clover" bootloader (Google is your friend) and install on a USB stick
and
If your Hackintosh is currently using a DSDT file, go to EFI -> ACPI -> patched inside the USB drive. Then, open a second Finder window, go to the base of your main hard drive, and open the Extra folder. Inside that folder, you should see a file called "DSDT.aml". Drag this file into the patched folder in your USB drive.
Next, go back to the EFI folder at the base of your USB drive, and open the file config.plist in TextEdit (or any other text editor of your choice). In between </dict> and </dict> at the end of the file, add the following lines:
<key>RtVariables</key>
<dict>
<key>MLB</key>
<string>11111111111111111</string>
</dict>
Reboot with the USB stick and log in iMessage... it should work after reboot again without the stick and it should still work. (It work on my 2 hackintosh)
hope this help
(I don't take credit for this... just find it somewhere on the net...)
