Artlantis 4.1 is compatible with Mountain Lion, Apple's latest Mac OS X 10.8 operating system. No special issues were found during the performed tests so far.
Mac OS X 10.8 introduces a new security option called Gatekeeper. It prevents the installation of malicious software on a Mac. By changing its security settings in the Preferences > Security & Privacy dialog box, you can control and allow the installation of applications not certified for OS X Mountain Lion.
Please note, however, that Artlantis 3 was developed and tested with the earlier Mac OS versions only. We do not recommend running Artlantis 3 on Mountain Lion.
