thx that worked like charm.
has someone discovered a way on how to update to macOS Mojave PB2 without APFS Conversion ?
tried to use the noapfsconversion but it seems it's not available on the Mojave Installer.
The options formerly available for High Sierra are not available in Mojave (requires patching the Mojave installer, which is contrary to the rules around here).
Using CCC to clone back to HFS+J would probably work.
Heres a link to a converter. I haven't tested but if you update and get apfs you may use this to convert back to HFS+J. 334796-apfs-to-hfs-converter
Also, if you update or install using a USB to Sata convertor or external USB drive it stays in HFS mode. That may be an issue with NVME though.
Thanks for the information, to be honest i would prefer to stay on APFS but i have very bad experience with APFS on my Kingston V300 Now 120GB SSD.
The partitions have been corrupted 3x times so far that caused me some data loss and waste of 3 day progress on trying to fix some issues on my device (which caused me a clean install and doing the work and all the fixes & new SSDTs & new config.plist) for it.
So that's why im afraid to stay on with APFS on this SSD, it seems they don't go well with each other.
Um on the USB start install command once u type the --volume name of target that doesn't work the correct command is
/Volumes/"Image Volume/Install macOS High Sierra.app"/Contents/Resources/startosinstall --volume /Volumes/name of target --converttoapfs NO --agreetolicense
(In my example I used the name OSX so I would do --volume /Volumes/OSX and the rest of the command
Piker Alpha mentioned that apfs can cause problems with corruption due to hacks not having true Apple bios. I too have had corruption issues with apfs on some setups but others are fine.
Another method to avoid apfs is to do a direct install to an external USB drive or USB to Sata adapter. Doing this installs in HFS mode.
Yes, i have read his post about APFS.
However "vit9696" the guy who created (shiki.kext,lilu.kext,appleALC.kext) seems that he started on a modded apfs package for hackintosh.
So i assume it won't be a problem to use apfs in a couple or months.
When the bless command is used to make an APFS volume bootable, a copy of the APFS EFI driver (the version at /usr/standalone/i386) gets embedded in the APFS container. Apple's firmware is able to read the EFI driver from the container at boot using an ApfsJumpStartDriver that is part of the firmware.
ApfsSupportPkg is 2 EFI drivers and 2 ways to load the embedded APFS driver from the container partition. One loads Apple's own ApfsJumpStartDriver if you have a copy of it, and the other is a reverse engineered driver written from scratch.
