Firewire 2024: Today's Macs and Sequoia?

Yes, that appears to be the case. After re-enabling full security the MOTU was no longer recognised. Then when security was disabled again, it was necessary to reinstall the MOTU driver.

I notice both the TB and FW adapters become quite warm. I haven't been able to find any stats for the Ultralite's power consumption but imagine it must be quite high. Unlike USB devices, macOS System Report doesn't appear to list the current draw for Thunderbolt devices.

Reduced, not disabled.

The FireWire bus power spec was around 27W. The Apple FW-TB adapter only passes 7.7W if I’m remembering correctly—don’t know what the TB2-3 is rated. So, yeah, if bus power works at all, the adapters are going to get warm.

Wanted to thank Mike Halloran and others here for this great thread. Mac Mini M4 now running my FW 828mk2 flawlessly.

The only thing is often when I boot the computer there is a warning that the motu driver will not be functioning in a future OS update. So I guess that means they are going to cripple the FW code in the os, and if so when? I would just keep the previous version to keep my interface functioning if I knew which update to avoid...

Thanks again.

That message has been popping up for awhile. Hopefully, MOTU will rewrite the driver before it comes true.
