My wife uses a Mac mini. OS 12.6.2 with Super Duper 3.7 to back up every night.
She's been getting a message every day that she ignored (CANCEL)...
When I finally saw this message (see screen shots), I did "Convert to APFS". Not knowing what would happen other than it would take a "long time". Well, it went all night long and I had to Force Quit Super Duper this morning!
Can someone please explain what APFS means? Is it necessary? How to do it properly?Much thanks!
