Open project from MAC at PC

I created a new project on PC.

Then i move it to MAC, for iPad testing, then a move it back to PC and a got errors:

Shader wants texture coordinates, but the mesh cap doesn't have them
UnityEditor.DockArea:OnGUI()
Shader wants texture coordinates, but the mesh cap doesn't have them

I don’t see any model mesh. Where is the problem ?

Is this an compile or editor error? Can you play the game without getting the screen “You must fix all compiler errors”? If it not a compile error, you can just clear the debug log and ignore it.

Problem solved.
Problem has been in version of Unity.
On MAC i have newer version 3.5
and on PC I have 3.4.

After update all works.
