If you have an internal ssd model (or do what I did and installed one myself where the sata spinning portion of the fusion drive was) then Mojave is absolutely great.
However, with just a fusion drive, or worse, only a spinning drive, Mojave and the previous 3 or 4 prior OS's totally suck ass.

I kinda feel beginning with Sierra in 2016 that having a fusion drive started to become a significant penalty.

Have you upgraded your GPU? Because the stock GPU (mobile Radeon HD4850) on the 27" is not really going to work at all with Mojave/Catalina, because it doesn't support Metal.

thanks.created usb boot.Machine strarts booting from it ,then stops and shuts down or just hangs up ,a few minutes before finishing
hmmm. I've always had luck with it on the few machines I've tried it on. To be sure, it's basically an unsupported 'experimental' kind of thing. So the fact that a particular system balks at the install isn't entirely surprising to me.

One question though: What OS was the latest installed on that Mac? Ideally to get the DOSdude1 patcher to work, you would have installed the very latest OS that is officially supported on that Mac FIRST. Even though you're then erasing the drive, the most recent OS may have a firmware update that the DOSdude1 patcher is expecting to be present.

Specifically, did you install High Sierra on that Mac first? In a couple cases I had to install High Sierra (10.13) on Macs BEFORE Mojave, otherwise the Mojave install would hang - just as you describe.

The reason I think is that High Sierra and Mojave both do a Firmware update if you're coming from OS 10.12 (Sierra) or earlier. For some reason though, the Mojave installers attempt to do the firmware update has issues at times, while the High Sierra one does not.

Since your mac fully supports High Sierra, go ahead and install that first and then try your DOSdude1 installer disk again.

I am running two iMacs, early 2009 and late 2009 (20" & 27") with dosdude1 Mojave. Both are at the latest updates, both are running SSD's with max memory. They run exceptionally well, no issues.
