Slow boot time issue

Hi all,

I built my first Hackintosh recently and got it mostly up and running with no issues, but I'm experiencing a really slow boot time after selecting Mojave in Clover. Once the Apple logo appears, the status bar is pretty quick up to about half way and then it takes about a minute to make it to 100%.

Here are my build specs:

Motherboard: ASUS Prime Z270-A LGA1151
Processor: Intel i7-7700K
GPU: Gigabyte Radeon RX 580 - 8GB
Memory: G.SKILL Trident Z RGB Series 16GB
Hard Drive: Western Digital WD Blue 3D NAND 500GB
Cooler: Corsair H115i Platinum RGB

A couple of other things:

1. I followed Margate's Sierra - ASUS Prime Z270-A i7 build instructions (but with Mojave) from TonyMacX86
2. I've checked and Debug is not enabled in my config.plist

Could anyone help me figure out what it causing the slow boot?

Thanks.
