This METADATA editor MAY be “pro standard”, but I won’t know until I pay the 195 EURO asking price :-( Anyone tested BLUE GRIFFON ? Is it worth the money ?

Would have used SIGIL, but doesn’t work on my “old” MAC 10.6.8
I don’t need anything as fancy as Blue Griffon, so maybe need to upgrade my MAC ?
