For the last couple of years it has seemed like Oracle on Mac was on the up-and-up. Oracle’s new TOAD-like tool SQL Developer supports Mac OS X, you can deploy the detabase itself on Mac Servers (although not 10.2 as yet), etc etc. However, now I find that there is no ‘full’ client install which works on Intel Macs. Not only that but there are apparently no plans for it either. Take a look at this forum thread for a rather odd response from Oracle.
