Will the Pentium G4620 work with iMessage and Intel HD 630?

[TheSmallestHack]

I've been planning an ultra small form factor hackintosh.  I impulse bought a G4620 on sale for $60. Since then I've read a bit more and I've seen some people say that iMessage/HD 630 do not work on a pentium based hackintosh. The original plan for the G4620 was to use it as a machine to learn on then build a proper machine and use the G4620 as a server/spare computer/give it away/or perhaps just keep it if performance is good enough. I'm starting to think I just want to keep the first machine I build unless there are major compatibility problems though. I have an ASRock Z270M-itx/ac on the way and already have RAM/some SSDs so I'll be building soon, but I can still sell the unopened G4620 for ~$80 and buy an i5 if the pentium isn't compatible. I tried to search but I found too much conflicting information. Please get as technical with me as possible and point me in the right direction to learn more. I'm mostly just building this machine for fun and to tinker with.

 

So:

1. Will the G4620 work with iMessage? Bonus points if you can point me towards more info on the topic.

 

2. Will the G4620's Intel HD 630 integrated GPU work with Mac OS and sleep/wake properly? Bonus points if we can get technical/point me towards more resources on this. 

 

3. How compatible is say a 7600K with Hd 630 and iMessage?
