diskutility in 10.13 does no longer allow to format new volumes using HFS+.
but you can reenable that for specific volumes.
1. go to diskutility, choose the disc or volume you want to format, go to reformat page.
2. note down the identifier of the disk in question (diskxxxx)
3. go to terminal and type:
user$ diskutil apfs deleteContainer diskxxxx
diskutility will now show all four old options, HFS+ with or without journalling and with or without encryption, in the menu and you can select one of them (probably without encryption for MacOS9/PPC) and format the volume.

Because Mac OS 9 was written for PPC, I am not sure why its even working under Intel Macs ? Next I will ask if its possible to do all this under Catalina or Mojave with a 2015 MacBook Pro Retina ?

If you're talking about HFS+, that was used as the primary filesystem from Mac OS 8.1 all the way to 10.12 IIRC. So there's plenty of Intel support for it as well.

I think you misunderstood me - Mac OS 9 is for PowerPC processors, Catalina and Mojave run x86 intel Macs.. While you could install if under HFS+, it won't boot at all since Intel code does not speak to PPC code, unless you are referring to SheepShaver or QEMU ?
If someone can get OS 9 to run on intel hardware natively, let me know.

like he correctly pointed out, HFS+ was an valid filesystem for up to 10.12.
in 10.13 it is no longer shown in the frontend now.
that filesystem has nothing to do with OS9 or PPC, except that someone might want to format a disk for those using a mac running 10.13 or higher.
or for 10.12 for that matter.
because if you format a disk with APFS using 10.13, you can not even use it under 10.12 or 10.7

Sorry, my mistake. yes that is true - HFS+ goes from 10.12 to 8.1 - but to install Mac OS 9 you would need a PPC machine, unless OS 9 had a version for x86.

That is true. This post isn't about installing OS 9 though, it's about formatting new volumes as HFS+ under 10.13 and later.
Thanks IIO for the info, btw ;)
