Hi, folks.
Firestorm does not recommend disabling security features.
Mac users have always needed to tell Gatekeeper to allow Firestorm to open (only on first launch after installation). The steps are documented on https://wiki.firestormviewer.org/fs_mac, and for recent Mac operating systems they consist of about 6 clicks, taking about 5 seconds. To our knowledge, there have not been any Mac users who were unsuccessful with these simple steps--if they were done correctly. Any Mac user having trouble should ask in one of our support groups or file a Jira ticket with us.
Thanks,
Anastasia Horngold
