    "Just remember to install Kext Correctly."

    Sound like something they should teach you at school.

    By the way, I have another computer (same as this one) but without a GPU that I will update next week. It should go much smoother! I have definitely learned a lot.

    Better to avoid APFS conversion on a Hack. Stick with HFS+.
    I didn't migrate to APFS on my Desktop. Read Post #10.

    Same here, On nVME Samsung EVO 960 it takes 20sec or less. I'm with you its not that problem to break a working set-up. But I like to get it solved. I tried nvram erase / SSD trim turn off / And rebuild caches. It looks that it rebuilds the whole kextcache every time because I see a lot sustained access to the nVME drive. ... reading... reading... Wonderfull You found the fix! There are two questions remaining for me and possibly for others as well:
    1. Why is this delay happening with APFS?
    2. Why is this delay happening also on my daughters iMac 21,5 inch?
    The common factor is that in 1) a hack is used with an unofficial SSD (nVME Samsung EVO 960) and in 2) there is an unofficial supported SSD used (Samsung EVO 850).

    Next weekend I make time to get rid of APFS and go back to HFS+ as mentioned clearly explained by Rehabman. Further I'm impressed by VioletGragon and Rehabman how committed those guys are to help baryw. I would like to share my honest respect to those guys.

    VDragon - Today I updated my system from the latest beta to Release. Regrettably all the work we did to fix sound didn't stick. I am back to not seeing any outputs.

    I did re-read all of our notes and you mentioned that after an update I should run a command in the Terminal two times. I ran it three times but no luck.

    The info from terminal wasn't anything with errors. Standard responses as far as I could tell.

    Not sure if it interests you but do you want to troubleshoot? I can send you my output if you want. Did you have any issues when you updated?
