Hi @gavaza! Thank you for reporting this. First I thought it is similar issue like the one described in README, but then after working around signal 9, I got following:

Barboras-MacBook-Pro:Mac-Hroot jajo$ sudo ./chroot.sh mac-jail/
mac-jail$ /Applications/Safari.app/Contents/MacOS/Safari 
Segmentation fault: 11

In dmesg I see following messages:
