In post #1, at the "Installation" part, I think there is a typo: 5912000 should be 59120000.
After the 10.13.4 update, many people (including me) have experienced graphics flickering with Intel HD 630 / UHD 630. I read that some people could fix it by changing iMac18,x system definition to iMac17,1. (

What do you think about it
@toleda? Is it still worth using iMac18 sys def with HD 630 / UHD 630?
I really don't want to change my sys def because it could brick iMessage, mess up iCloud and so on...
Thank you in advance.
