Hello Alecwild, I will answer to the best of my ability...
2. how to fix iMessages/FaceTime. you need information from a REAL mac to do this. Hex edit the ozmosis file and replace the ROM and MLB values that you have scavenged from a real mac. remember it has to be in HEX because they have non printable chars to make it so that you can not just copy paste them.
3. yes, it is a common issue, you will also sometimes get an error on startup saying that the SMC controller is not working correctly/caused a bad shutdown.
hope this helps.
2. iMessage. All of the online fixes for iMessage are for Clover/Chameleon bootloaders. Is there any known fix for Ozmosis?
3. Apparent freeze at shutdown (but I'm not sure). At OS X shutdown, the dock starts to sink, then freezs halfway down. Then my hack shuts off. The fans go off, everything seems normal. Boot is normal (and fast). Is this a freeze that's happening?
I'm new, but brave and willing to learn. Any advice?
