XDJ-XZ Firmware Update Fails

Dear Pioneer,

My firmware update fails although I took all the advices on the guide.

I downloaded twice with different USB devices thinking either the usb or the file is corrupt  (usbs are the ones that I always use at my sets). The update does not start automatically. The bar doesn't show at all. Only "Connect USB storage device into top USB1 port" shows up and nothing happens after that.

- Current firmware:1.23

- Rekordbox ver: 6.6.11

Macbook Air early 2014, Catalina 10.15.7

I'd appreciate your help.

Thank you,
