Poor performance in editor on OSX - is this normal?

[czater]

Hello!
I just started developing games on OSX and I have poor performance in editor, simple drag and drop prefab to script is lagging, simple flappybird-like game is lagging, switching gameobject position in hierarchy…lagging. I have no idea what is going on, my macbook isn’t that bad (mid 2014, i5 2.8/8gb/512ssd/iris 5100). Apk build time is fine (even better that on my Win machine).
Is this possible that openGL 4.1 makes that big diffrence? Can I run directx version on OSX?

Did you just upgrade to a new version of Unity? We have a case where some larger projects would cause performance issues in the Editor.

A while back I had disabled “Compress assets on import” to save time when messing with textures and whatnot. I haven’t experienced any problems for several months. After upgrading to 5.5 many assets were re-imported automatically. I believe this caused them all to become uncompressed, including ones that had been compressed previously due to building. All these uncompressed assets were then being loaded into memory when I opened a large scene.

This also aligns with a similar issue our audio designer was encountering even before the 5.5 update. He never builds the project, leaving any new assets uncompressed on his system compared to the rest of us.
