So I purchased the Lightroom/Photoshop subscription, and that doesn't seem to work either -- trying to run the installer from the DMG I get:
“Lightroom Installer” can’t be opened because Apple cannot check it for malicious software.
I realize Catalina is still in beta, so the answer might be "wait for Apple/Adobe to fix things" but I'm hoping someone has suggestions.
EDIT: I can get past that by holding down control while clicking "Open" on the DMG, but I immediately get the error on a second installer that the first evidently spawns. Then the LR installer gets to 13% or 14% and just hangs.
