[Bug 2002214] Re: Installing 22.04 on mac OSX does not propose Dual Boot option

[Michel-Ekimia]

Although the manual installation detects the EFI partition and adds the
Ubuntu bits

ubuntu at ubuntu:/mnt/EFI/BOOT$ ls -la
total 1855
drwxr-xr-x 2 root root    512 janv.  7 15:55 .
drwxr-xr-x 5 root root    512 janv.  7 15:55 ..
-rwxr-xr-x 1 root root 955656 janv.  7 16:06 BOOTX64.EFI
-rwxr-xr-x 1 root root  85672 janv.  7 16:06 fbx64.efi

Title:
  Installing 22.04 on mac OSX does not propose Dual Boot option

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Imac 8,1 with Mac OSX 10.11 with journal disable on HFS+ system
  partition :

  Booted on Pure EFI ( No Bootcamp nor Refind )

  Ubuntu 22.04 installer would propose only :

  - erase all the disk and install 
  - Something else

  it should propose like on a windows EFI machine

  - Install along OSX ( I even prepared 120 GB free on the disk for that
  )
