[Guide] Avoid APFS conversion on High Sierra update or fresh install

Why a mess? The config is the extracted wisdom of 8 years Sony Vaio Hackintosh. It has to be like this. You mean that there are obsolete files inside? What were you searching for, the smbios settings? I recently switched to MacPro6,1, since else I get a black screen with recent nvidia web drivers.

Examples:
- kexts not installed correctly
- ACPI/origin files from July 2010!
- FirmwareFeatures/Mask specified in config.plist instead of using Clover defaults

At that point, I stopped looking... Easier for you to use a USB for installation...
 
Oh, now I get it! I should make a HS install stick!

But I guess it is not working because of missing EfI partition.

All GPT partitioned disks by Disk Utility have EFI. The macOS/OS X installer requires GPT.
 
Because I removed it by purpose. The SSD is formatted as MBR, only containing the system partition. This was necessary because of the lame sony bios, which cannot handle EFI boot properly. There is no bios update available, too.

Hm, so I need that MBR installer patch, I guess.

Fresh install scenario (or update) using 'startosinstall'
Code: 
/Volumes/"Image Volume/Install macOS High Sierra.app"/Contents/Resources/startosinstall --volume the_target_volume--converttoapfs NO --agreetolicense
Click to expand...

i'm still confuse about "the_target_volume", should i replace this with my IDENTIFIER or anything else ?
Code: 
/dev/disk1 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *160.0 GB   disk1
   1:                        EFI EFI                     209.7 MB   disk1s1
   2:         Microsoft Reserved                         16.8 MB    disk1s2
   3:       Microsoft Basic Data Untitled                90.1 GB    disk1s3
   4:                  Apple_HFS Mac                     69.0 GB    disk1s4
   5:                 Apple_Boot Recovery HD             650.0 MB   disk1s5

It is the name of your system volume. You named your system volume 'Mac'
 
Is it possible to prevent the conversion when restoring from a Time Machine backup? I rarely perform fresh installs and usually restore from Time Machine backups instead.

If the TM backup is an HFS+J backup, I would expect no conversion.
