I recently burned 4 Blu Ray 50 gb discs with DropDMG’s burn feature. I selected full disc image for each disc. Now when I mount the discs they appear on my M1 Mac desktops without any icon. I can see the text name of the disc and can click on it to open the disc and the dmg file is there and functional. I just can’t see a disc image in finder on the desktop. Can you test on your end. I am running OS 11.2.1 on an M1 MacBook Air and M1 Mini. Current version of DropDMG 3.62.
