Mojave has no support for the Celeron G1840, High Sierra - it works fine, in the Mojave - as if the XCPM is turned off (turned on in the configuration), I tried different settings, versions of the clover. P.S. AppleHDA had to be removed - buggy. P.P.S. HWmonitor only reads three fan slots - CPU 4pin, CHAFAN1 and 3pin fan for power (perhaps, because there imac only 3 fans on the aimag, it can add fans when changing the settings of the clover on the macpro.)

Clover 4635 (for 10.13.6) supports, just turned on XCPM. Intel HD really does not work, but you can install, run with an argument "-x", without the support of acceleration. With nvidea normally installed, working.

With Celeron G1840, you also need to enable XCPM in the configuration.
