Connecting to iDevice: Done!
Device is not in pwned DFU. Exploiting now.
Exploiting iDevice: FAILED!

while if I try to launch Fugu in VirtualBox (windows10 host mac guest) with macOS Mojave 10.14.4 i have the following output:

Checkm8 (the exploit used by Fugu) cannot work in a VM as it requires USB passthrough

Correct! next option could be dual boot, rather than VM.

After wasting a 2 days weekend, there were some experience that I want to share with you (or the one who want to try in future)

• ALL ARM (i.e. M1, M2) MacBook were not supported, you will stuck at "stage 1" and your iPhone reboot
• MOST OF the USB-C to lightning will not work, and exploit failed
• Best practice: USB-A to lightning + Intel MacBook + hub(for non-USB-A MacBook)
