September 26, 20241 yr Hopefully this issue can be corrected, but in the meantime here's some help for you Mac users. I've been pulling my hair out trying to create a bootable Unraid USB drive (legacy not UEFI, because.. reasons) on my MAC. The USB Creator App for Mac works fine. The issue is with the scripts to make the USB drive legacy bootable. I tried this on an Intel based Mac, and Apple Silicon with the same problem. When I go to run the "make_bootable_mac" script it runs as far as copying syslinux to /tmp/UNRAID/syslinux where it runs another script from /tmp/UNRAID/syslinux "make_bootable_mac.sh" that fails at the final step "/tmp/UNRAID/syslinux/syslinux -f --install ${TARGET}s1 1>&3 2>&4" If I execute the necessary steps manually, repeating that last command twice, it will actually work: Note the USB thumbdrive is mounted as /dev/disk4s1 goodbeer:syslinux dawg$ sudo dd if=/tmp/UNRAID/syslinux/mbr.bin of=/dev/disk4 0+1 records in 0+1 records out 447 bytes transferred in 0.054336 secs (8227 bytes/sec) goodbeer:syslinux dawg$ sudo /tmp/UNRAID/syslinux/syslinux -f --install /dev/disk4s1 syslinux for Mac OS X; created by Geza Kovacs for UNetbootin unetbootin.sf.net "/dev/disk4s1" unmounted successfully. /dev/disk4s1 DOS_FAT_32 /Volumes/UNRAID mountpoint is '/Volumes/UNRAID' checkpoint1 checkpoint2 checkpoint3 Processing: /Volumes/UNRAID/ldlinux.sys checkpoint4 checkpoint5 checkpoint6 checkpoint7 Processing: /Volumes/UNRAID/ldlinux.c32 checkpoint8 checkpoint9 checkpoint10 hdiutil: unmount: "/dev/disk4s1" failed to unmount due to error 49168. hdiutil: unmount failed - Resource busy couldn't open device: Resource busy goodbeer:syslinux dawg$ sudo /tmp/UNRAID/syslinux/syslinux -f --install /dev/disk4s1 syslinux for Mac OS X; created by Geza Kovacs for UNetbootin unetbootin.sf.net "/dev/disk4s1" unmounted successfully. /dev/disk4s1 DOS_FAT_32 /Volumes/UNRAID mountpoint is '/Volumes/UNRAID' checkpoint1 checkpoint2 checkpoint3 Processing: /Volumes/UNRAID/ldlinux.sys checkpoint4 checkpoint5 checkpoint6 checkpoint7 Processing: /Volumes/UNRAID/ldlinux.c32 checkpoint8 checkpoint9 checkpoint10 "/dev/disk4s1" unmounted successfully. checkpoint11 checkpoint12 checkpoint13 checkpoint14 checkpoint15 /dev/disk4s1 DOS_FAT_32 /Volumes/UNRAID syslinux installed successfully!
