Hi David, Regarding macOS Sierra 10.12.x and comparing v15.3 to v15.4 I would say that 15.4 is the only answer (not just best).
v15.3 is not certified for Sierra and a compatability note exists in the release notes: ftp://ftp-public.4d.fr/Documents/Products_Documentation/LastVersions/Line_15/VIntl/4D_v15_3_ReleaseNotes_US.pdf v15.4 is the first v15.x release to be certified for Sierra: ftp://ftp-public.4d.fr/Documents/Products_Documentation/LastVersions/Line_15/VIntl/4D_v15_4_ReleaseNotes_US.pdf { 4Dcertified onnewOSs This minor version is certified on 2 new OSs: Windows Server 2016 and macOS Sierra (10.12.3). } -Tim ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
