We have done some testing on the new OSX 10.7 from Apple and have not found any issues in onCourse. In fact, some of the user interface looks nicer with the new squarer look of OSX!

Having said that, our test machines we have upgraded currently perform worse overall than under 10.6. Bluetooth headsets don’t work for us and there are significant slowdowns to the whole machine (not specific to onCourse). Our advise is wait for 10.7.1 to patch a range of issues before leaping forward. And then leap forward in very small hops, one machine at a time.
