I’ve reinstalled UT (“Verify” command) and finally realized that what’s happening is if I launch the UT default project from the Unreal Engine Library area, it always hangs at 72% whereas if I simply “Launch” from the UT Create area, it always works. Mind you, it took a couple days for me to catch on as to why it was hanging so frequently when I tried to launch but it finally clicked today.
Don’t know if this is just my Mac or just the Mac platform, but that’s what I’m getting at the moment.
