Hello, Does anyone know whether MacOS-X 10.5 (leopard) will be immediately compatible with Psychophysics Toolbox? Do any of the changes change things in a way that could cause problems? Thanks, Rob -- [http://www.nmr.mgh.harvard.edu/~levy/](http://www.nmr.mgh.harvard.edu/~levy/) ---

Given that Leopard isn't available yet, no one can know. But from the technical specs that are available at the moment, i wouldn't expect any incompatibilities by design. Of course its always possible that Leopord contains some new bugs along with all the new features and these bugs could interfere, but that wouldn't be by design. I hope that there will be a few significant improvements, especially in the areas of anti-aliasing and fast creation of high-precision/HDR stimuli. Tiger lacks a few useful functions there which are available on Linux and Windows since over a year. Timing behaviour is also an area where i would expect some further improvements, given the redesigned scheduler (now optimized for multi-cores), although the quality of timing of Tiger was already lightyears ahead of the beautiful products from Redmond. -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), Robert Levy \ wrote: > \> > \> Hello, > \> > \> Does anyone know whether MacOS-X 10.5 (leopard) will be immediately > \> compatible with Psychophysics Toolbox?

OK, I just installed Leopard (on my macbook pro) and so far psychtoolbox seems to be running well. I am not sure if I would recommend upgrading experimental machines to Leopard quite yet, but at least it seems fine for code development. If anyone wants me to test something specific let me know (so far I have tested dotdemo as well as some of my own experimental programs).

thanks for doing this. Could you also run StereoDemo(1) and tell me if it properly switches into frame sequential stereo mode, ie. you see the flickering/alternating stereo stim and the sync line drawn at the bottom of your screen? thanks, -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "aseitz" \ wrote: > \> > \> Hi Mario, > \> > \> My Macbook Pro has the GeForce 8600M GT video card with 256MB of RAM.

Apparently they work with the NVidia Geforce8600M inside the new MacBookPro's - both on Tiger 10.4.10 and Leopard, and also with the NVidia Quadro. However that doesn't guarantee they work with anything else. Support is completely driver dependent, so its up to NVidia/ATI/Intel which cards support it with which OS release. We'll see. On OS/X lack of beampos queries is not that much of a problem, you only lose a little bit of accuracy: PTB uses timestamped hardware interrupts (vbl interrupts) on OS/X to get pretty ok timestamps if it can't use beampos queries. Order of accuracy/robustness: 1. Beampositin queries are best - as good as +/- 20 microsecs jitter on some hardware/OS. 2. VBL interrupts on OS/X can be as good as +/-100 microsecs, but they are always submillisecond accurate at least. 3. Standard timestamps are sub-millisecond on OS/X and Linux most of the time, but its not guaranteed. On Windoze, they are (nearly) guaranteed to be worse than 1 msec - pick an arbitrarily high number as upper bound for the worst case. -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "Peter Meilstrup" \ wrote: > \> > \> Does this mean the beamposition queries on Intel are working now?
