MP 1,1-5,1 APFS doesn't boot after successful dosdude1's APFS patch

[Ezzio]

Hello.

I followed Hrutkay Mods's tutorial and, has I have an Intel MacPro 3,1, I proceeded to apply dosdude1's patch to the ROM. The process went smooth and I then verified with UEFITool that the APFS driver is installed. Everything seems fine: I can find "APFS" in the ROM image (please check attachment).

So, I deleted the old High Sierra setup with dosdude1's bootloader, initialised again the SSD drive with APFS and installed again High Sierra, patched by dosdude1, this time omitting to install also the APFS patcher in the post-install options.

However, much to my disappointment, when I rebooted the machine, I get a "no entry" icon and, after a while, the Mac shuts down.

The APFS driver is in the ROM, I cannot understand why it doesn't work. Btw: I did not reset either the PRAM no the SMC.

What did I do wrong? Thanks in advance.

-Just ran across this post so it may have been answered already, but I'l give you my experience: I'm on a cMP 3,1 and installed High Sierra on an HFS+ volume using Dosdude1's installer without any issues. Moving up to Catalina I first formatted a new drive as an APFS volume with the standard disk utility and then ran Dosdude1's Catalina installer (the most recent version automatically runs the appropriate patches for your cMP 3,1 without any intervention). When finished and restarted, the system preferences window shows the APFS boot at the bottom. Note on first and subsequent startups you should see a (yellow text) verbose list scrolling in preparation for booting from an APFS volume. Hope that this helps, but I'm not familiar with modding the bios on these cMPs
