Yes Julian I now have the problem (in my case anyway) found.
I have a Hackintosh HackBook, is a Medion Akoya P8610 but runs as an iMac 10.1 SMBIOS, other versions of SMBIOS, like MacBook 5.2 (most similar to the hardware) does not work.
Ok now for the update from 10.14 Final to 10.14.1 and 2.
Install .. after the 1st reboot then again from the USB stick dosdude1 Mojave Patcher run and just this time not my iMac10,1 but I just once on suspicion then iMac 12.2 selected. Then select the appropriate patches as always. And lo and behold, he then boats without problems and installed to end.
With the repeated attempt (out of curiosity), he then also with the selection iMac12,2 not continue .. then I just once iMac12,1 selected and lo and behold, he then boot after reboot and installed properly to the end.
Why is that so coincidental that it works?
Previously at Betas 10.14 (Beta1 through 11), there were no such issues.
Incidentally, with the wonderful tool of gengik84 (User in insanelymac forum) the MacOS_Updater (so you can install Mojave on HFS + synonymous now update the 10.14 to 10.14.1 and 10.14.2) I hang the tool times in the attachment with it. Therefore, APFS is no longer necessary on our Hackis and your original Macs.
