The title says it all. We ran the xTuple client through our test battery on the lastest Apple operating system and it has passed with flying colors. As of today we officially support running our published xTuple 3.7.4 distribution on Macintosh Lion.*
*Note however, that PostgreSQL 9 that ships with Lion is not currently supported. xTuple 3.7.4 must connect to an 8.3 or 8.4 database. If you use the xTuple installer it will install an 8.4 PostgreSQL database. Support for PostgreSQL 9 is coming in xTuple 3.8.0 which is currently in beta.
