COLOSSUS9 I used this app several times and it keeps damaging my ACLs on the start-up drive first, then the rest of the drives become effected. Including internal and external drives and made my machine incapable to boot from any drive attached to this machine. Basically, every drive had a lock on it and all ACL rights defaulted to "custom" instead of "read-write", "read" or "drop box". This only happened when I have installed this app, and I installed it 4 times. I had several techs look into this and we saw the damage to the ACLs happen simultaneously. We noticed it is when this app is installed. Even after we repaired my MacPro. We decided that this program is dangerous. Caveat Emptor.
