Both external disks connected by Thunderbolt 3 and USB3.1 to my 19,1 iMac Catalina 10.15.4 have been made both readable and writable by me the owner. I used the Apple+I window to do this. It is strange that I CAN CHANGE the ICONS of my internal 2TB SSD & my Time Machine Thunderbolt connected 1TB HD, but not the external drives that I use for extra backups. I have removed SIP protection, and tried to change the ICONS, but it did not work, so added back SIP. LiteICON app does not work.
Anyone know how to change the disk icons on these external disks?
