Hi! Sorry to hear that you're experiencing troubles.
v1.2-77 works on my Macs. As part of ongoing initiatives under the guise of "security," Apple have been making it progressively harder for developers to distribute games without engaging in Apple's distribution mechanisms, which is part of why I do not officially support anything newer than 10.14.
My best guess is that MacOS has "quarantined" Hive Time, and is displaying the "Hive Time is damaged" error when it would historically have shown a warning about the application being from an "unidentified developer." I'm uncertain why this is affecting the v1.2 build for you and not the v1.1 build, but you may be able to use the xattr command line tool with the -cr options to remove the quarantine flag from Hive Time.app.
Alternatively, you can install and run Hive Time through the Itch App, which will bypass that nonsense.
I would be interested to hear more about the glitching you were experiencing. If you have a save or a log file you're willing to share, please send that along with a description of the behaviour you were seeing to the support address listed in the "Technical help" section here on the store page.
Hope that helps!
