Win10 - Passed QA. OSX - Failed QA.

Verified on the Second Life Release 7.1.11.10947335521 (64bit) on Win10/OSX in the scope of https://github.com/secondlife/iqa/issues/348.

OSX: The antialiasing option "FXAA + Low" is shown after choosing the "Mid+" or "High" graphics preset. The antialiasing option "SMAA + Low" is shown after choosing the "High+" or "Ultra" graphics preset (please, see screenshots below).

@AtlasLinden, could you please clarify, if the SSR is the "Screen Space Reflections" option in the "Advanced Graphics Preferences" floater? Thank you.

Hi @dmytrohproductengine, Yes SSR is Screen Space Reflections which is found in Advanced Graphics Preferences. And it seems I didn't take into account the change that is made for Intel Macs in the above test plan. That is, the AA Quality is always going to be Low for Intel Macs. Thanks for verifying on this machine. Both of these comments have been updated in the above test plan
