Mojave 10.14.2 - Slow Boot / Warning and Failure Messages in Verbose Mode

[Vaultnaemsae]

Hi forumites,

 

Total noob here and my first post so please be gentle. I hope maybe somebody could point me in the right direction here

 

I replaced my mid-2015's MacBook Pro Retina's OEM 500GB SSD with an EVO 970 2TB NVMe M.2 SSD a couple of months back while still on High Sierra. I used APFS when I set up the 2TB SSD based on some 'not great' advice. I then experienced a couple of issues with very slow boot time.

 

After much searching, I determined that this problem was related to HFS+ vs APFS (based on some advice found on tonymac86x).

It was next recommended that I install Mojave 10.14.2. as this issue was allegedly resolved in this version. I did this with trepidation as some software I use is still not officially compatible with Mojave.

Mojave definitely improved the speed a bit but the boot still hangs. In verbose mode, I can see the point where the boot process hangs.

 

Everything runs seemingly smoothly then...

 

“FIPSPOST_USER [3722302532] fipspost_post: 197: all tests PASSED (213 ms)

”

..Then it hangs but starts again after some time.

I'm not sure what these messages mean(there are some earlier things that look concerning too) and Google has not been my friend when trying to find out what they mean.

Total boot time ranges between 34-60 seconds.

 

Could anybody please help me out here?
