CHANGE APFS FORMAT TO OTHER FORMATS LIKE exFAT

Mount the drive and in Disk Utility select its principal drive name in the left margin and choose Erase. Select exFAT. There is no changing a drive format from APFS to exFAT without wiping the entire drive and losing what is already on it.

In the Disk Utility app  on your Mac, choose View > Show All Devices.

In the sidebar, select the top entry for that Seagate disk, then choose Erase.

In Disk Utility are you choosing the top container? Are you booted to Restore Mode? Have you selected Show all Devices in the View menu?

Hey there bud, if you are running one of the latest macOS releases, you will need to Delete the APFS format first to reformat it to other format options; Open DiskUtily, then select the drive you want, then right-click, select Delete APFS, click on ok/allow/continue, then when it's done with that, right click on the drive again, it should go back to the original drive name from the manufacturer, then right click, click Erase drive, then pick the format you want.

good luck!

In the Disk Utility app  on your Mac, choose View > Show All Devices.

In the sidebar, select the top entry for that disk, then choose Erase.

I also only have APFS.

I have the same issue, the only option is APFS - did anyone already solve this?
