Perhaps Maya didn't exit properly and the preferences were reset? It seems to me that over the years I've seen mentions of the same thing for other plugins, like mayatomr. The "auto load" is saved as a preference in ~/Library/Preferences/Autodesk/maya/2017/prefs/l If MtoA is not loaded when you start Maya, then open the Plug-in Manager, find mtoa.mll, select the the Loaded check box and the Auto-Load check. MtoA is now shipping with the Arnold 5.0 core.Changes v3.2.0.2 (April 10, 2019)MtoA 3.2.0. Maybe these are mac only issues am not sure but I am finding the experience a bit nightmarish. Solid Angle Maya To Arnold v3.2.0.2 for Maya 2017 to 2019 (Win/Mac/Linux)Arnold for Maya (or MtoA) provides a bridge to the Arnold renderer from within Maya’s standard interface. You close out maya and open it the next day and suddenly arnold won't load. Very frustrating trying to learn and program when you close it and then your hotkeys are gone when you reopen it. I am new to maya and am finding this 2017 release to be full of bugs and malfunctions.

If you find the solution please post the answer. Other people will come on the thread looking for solutions to the same issues and the thread will die there. It would be great when people have issues, that they then learn to solve, they didn't say, never mind found it.
