Mac always sees Super 6 in bootloader mode?

After I updated the firmware, every time I have the S6 connected via USB, MacOS sees it as being in bootloader mode (including on new computers the S6 hasn’t been connected to before).

This also happens with my Nymphes so I assume it’s some Mac weirdness… does it matter? Anyone else encounter this and know of a way to get it out of bootloader mode?

It looks as though there are 2 partitions in Super6’s flash memory. Bootloader is (Shift)+(Power). User Patches, Arps and Waveforms are (Patch)+(Power). This drove me crazy, until the penny dropped. I even thought I had bricked my Super6.

My computer is an eMac with CRT display (so absolutely ancient).

Hope that helps.
