I am not the original poster, but I can verify – having just downloaded the latest test version...
that there is a Readme in the DMG that says there may be a delay the first time 
that it opens immediately the 2nd time 
that while it is seemingly hung there, Activity Monitor says it is churning away at a task called XprotectService. For me (4,2 GHz Intel Core i7) it had 3 threads at 98% for 2 minutes 30 seconds.

…a small price to pay.

I'm trying to open DCPomatic Player 2 (version 2.12.5) on a mac i7 with current software and it keeps hanging on "Verifying..." but then eventually opens after about 5 minutes.

​ I've used it before and not had this issue. I just re-installed and same issue. Hmm.

Did you try to close and re-open it immediately after it finally opened for the first time?

Did you notice there is a readme in the DMG?
