Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Dark patches on surface

Hey, im having some trouble with dark patches appearing on the surface of my models when rendered.

I think it may be the geometry especially in the corners, if you can help at all please do.

Here are some images:

perhaps it is because your geometry is a little messy. you should stick to 4 sided polygons. and if you have edges close together they will create a harder edge or pinch in your case.

...is it a macbook?

i don't think you necessarily need to make your polygons 4 sided if you're modeling a hard object. it may be that your normals are messed up - but i'm not sure why that's not showing in your view port. i'd definitely try to clean up the geometry a bit though at the corner - try to get rid of that sharp corner.
