Blender freezes when trying to bake normal map I am trying to bake a normal map for a model I made but keep encountering the problem that blender freezes up for hours when I try to bake the normal map from a high poly to a low poly version of the mesh (with the help of a cage) And at first I thought it is my bad laptop (4 gb ram, i7-4700MQ CPU 2.40 GHz, NVIDIA geforce GT 740M ) but on a better computer it still froze up, on which I never had issues with baking before.

Could someone take a look at the file and see if something is wrong with it? Because I can't find a cause..

Ok, 
I downloaded your file, baked a 2k normalmap and it took me less than 5 min (Macbook Pro). 

So, I could not reproduce the behavior you mentioned and the only thing I changed was to reduce the preview subdivision of your multiresolution modifier on the highpoly mesh.
