<p>Sequential S3D is vanishing. Zspace uses it for their windows only apps. Nvidia barely supports S3D as a technology. Not sure if any other chip makers are using sequential anymore. Chip electronics have outpaced the need for sequential.</p>

<p>SBS half, the chimera DTI option output as HDMI is your best bet, regardless of the OS. </p>

<p>Some of the Samsung tv/monitors that do hdmi 2.0 now offer SBS half at 4k.</p>

<p>This resolution is better than bluray S3D framepack under HDMI 1.4, and is probably the best you will get for the foreseeable future (ie, 5-15 years).</p>

<div>Hi Peter,
<div class=""><br class="">
</div>
<div class=""> If Chimera says "Unable to find hardware stereo support … “ when you enable sequential stereo it means the graphics driver does not support quad-buffered OpenGL stereo. Unfortunately Apple has not been interested in supporting stereo so I’m
surprised you had it working recently. For several years now no machines Apple sold supported stereo. We had an ancient (8 year old) Nvidia Quadro FX 5600 in a Mac Pro until about 2 years ago, but the performance became so poor we abandoned it and had to
switch to Windows. The new Mac Pro cylinders did not support stereo.</div>
<div class=""><br class="">
</div>
<div class=""> Unfortunately Apple also doesn’t seem to provide any information on which systems support stereo. We used to be able to get this information from the Apple OpenGL Capabilities web page</div>

<div class="">but they stopped updating that two Mac OS versions ago (10.9). Now the only thing I can find from Apple about OpenGL support is this page</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span><a href="https://support.apple.com/en-us/HT202823" class="">https://support.apple.com/en-us/HT202823</a></div>
<div class=""><br class="">
</div>
<div class="">that lists the OpenGL version supported by each of their computers. Quad buffered stereo is not a requirement of any OpenGL version so this page does not help find out about stereo support.</div>
<div class=""><br class="">
</div>
<div class=""> With Mac OS El Capitan (10.11) Apple has talked a lot about “Metal” which is an alternative graphics programming interface. Chimera does not use it since it is Apple only and we need to support Linux and Windows.</div>
<div class=""><br class="">
</div>
<div class=""> In summary, I think Apple has dropped support for stereo on your systems. Could you tell us what graphics card it was working with and which Mac OS version (Mavericks 10.10?). Also if you use Chimera menu Help / Report a Bug… we will know
the configuration that no longer works which will help us advise other Chimera users.</div>
