Update Conbee II firmware on Home Assistant installed on Raspberry Pi 4B

I’d like to update my Conbee II dongle to the latest firmware that should be the deCONZ_ConBeeII_0x26720700.bin.GCF.
It runs on a Raspberry Pi 4B with Home Assistant latest OS.
I’m working on Mac Os personal computer, I don’t have a windows based pc.
How can I do?

You need a windows pc or a native Linux installation. Otherwise it’s going to be hard.
