Al Harding 0 Report post Posted January 14 Hello all, My Mac, unbeknownst to me was on Auto-update and I'm unwillingly on Mac OS Big Sur..Most apps work. RTI Builder comes up as 'damaged. I tried the usual fix, to open apps from "anywhere" but that hasn't worked as of yet. Has anyone else run into this? If so, is there a fix? Many Thanks to all, Quote Share this post Link to post Share on other sites
