Ive tried that, its not working for me. :/
Edit: Looks like I was using "retinizer" which was causing it to stay in retina mode even with low res checked. I "de-retinized" the app check the setting you mentioned and its now working fine.
Thanks! This worked for me on Retina Macbook probarsam wrote:I've got a better solution for the moment. Until the support finds out an fix it... (within the next 6 months)
Left click on the Simplify3D application and choose Get Info.
There is a check box saying "Open in Low Resolution". Check this and you are done.
