OpenGL Support on OSX 10.5
Updated March 28, 2019
ProSelect uses OpenGL libraries to directly access the graphics hardware on your computer when playing slideshows because they run smoother on slower hardware and allow us to use effects like the Ken Burns effect. You can still play simple slideshows in ProSelect without OpenGL support turned on.
As usual, if you are on a lease or your PLUS is current at the time of this release, ProSelect 2019r2 will be a free upgrade for you. As of today, if you are using an earlier version of ProSelect and are considering an upgrade to ProSelect 2019r1 then you will be entitled to get the 2019r2 version for free as part of the 6 months PLUS that is included with your upgrade.
