I am in the market of buying a iMac Pro but I do not want High Sierra on it. I would like Mojave to be preloaded on it.  So when do you think it will be included as a pre-install on a new iMac Pro?  i Plan to buy a 18 core, 16GB Video, 4TB SSD, 128 GB Ram, all the way.  I do video work and need a faster Mac. But I tried High Sierra and its not stable enough yet. Any ideas guys when Mojave will be released?  Any release dates yet?
