I am currently testing Lprof under OS X (it uses the latest Argyll with support for the Spyder) but I can't get the Spyder to be recognized - also not with the latest Argyll 0.70 beta build. The Lprof guys told me it might be necessary to add this "codeless kext" thing.
There's no Spyder support in 0.7 Beta 6, since I'm still working on this, and other things. It won't need a codeless kext in any case. Graeme Gill.
