I am trying to run an experiment using a mac OSX 10.9.4 with an intel HD graphics 4000. I am running my experiment using a second display in non-mirror mode. I downloaded the most recent update of the psych toolbox but I continue to get this problem:
PTB-INFO: Connection to Psychtoolbox kernel support driver instance #0 (Revision 0) established.
PTB-INFO: Disconnecting from kernel driver instance #0 for detected Intel GPU for safety reasons. setenv('PSYCH_ALLOW_DANGEROUS', '1') to override.
PTB-INFO: Running on OSX 10.9+ - Enabling protection against AppNap and other evils.
PTB-INFO: This is Psychtoolbox-3 for Apple OS X, under Matlab 64-Bit (Version 3.0.11 - Build date: Apr 6 2014).
PTB-INFO: Type 'PsychtoolboxVersion' for more detailed version information.
PTB-INFO: Most parts of the Psychtoolbox distribution are licensed to you under terms of the MIT License, with
PTB-INFO: some restrictions. See file 'License.txt' in the Psychtoolbox root folder for the exact licensing conditions.
PTB-INFO: Using Cocoa for this fullscreen window to work around various graphics driver bugs in OSX 10.8 and later.
PTB-INFO: Presentation timing accuracy may suffer and timestamps may be unreliable, depending on your specific setup.
PTB-INFO: Deficient Apple OS/X 10.7 or later detected: Would use fragile CoreVideo timestamping as fallback,
PTB-INFO: if beamposition timestamping would not work. Will try to use beamposition timestamping if possible.
PTB-INFO: Installation of the PsychtoolboxKernelDriver is strongly recommended if you care about precise visual
PTB-INFO: onset timestamping or timing. See 'help PsychtoolboxKernelDriver' for installation instructions.
PTB-INFO: However, if you use a Intel graphics card then don't bother, as the driver is no longer useful on such a card.
PTB-INFO: You are using a multi-display setup (2 active displays):
PTB-INFO: Please read 'help MultiDisplaySetups' for specific information on the Do's, Dont's,
PTB-INFO: and possible causes of trouble and how to diagnose and resolve them.
PTB-INFO: According to the operating system, some of your connected displays do not seem to
PTB-INFO: be switched into mirror mode. For a discussion of mirror mode vs. non-mirror mode,
PTB-INFO: please read 'help MirrorMode'.
PTB-INFO: OpenGL-Renderer is Intel Inc. :: Intel HD Graphics 4000 OpenGL Engine :: 2.1 INTEL-8.28.30
PTB-INFO: Renderer has 1024 MB of VRAM and a maximum 1024 MB of texture memory.
PTB-INFO: VBL startline = 1200 , VBL Endline = -1
PTB-INFO: Beamposition queries unsupported on this system. Will try to use kernel-level vbl interrupts as fallback.
PTB-INFO: Measured monitor refresh interval from VBLsync = 16.721588 ms [59.802933 Hz]. (50 valid samples taken, stddev=0.080377 ms.)
PTB-INFO: Small deviations between reported values are normal and no reason to worry.
PTB-INFO: Support for fast OffscreenWindows enabled.
Any help would be greatly appreciated
