After a long time, I have once again created a mockup for you. A notebook mockup without device branding etc. The PSD is very high resolution 4560×2850 and is therefore also great for printing. As always I wish you a lot of fun and success with it.
Incidentally, the 3D scene I used can be bought by Angelo Ferretti for only $ 5 on gumroad.com. It was created with cinema4D and corona.
The MacBook Pro 3D model is even available for free. Also created with Cinema 4D and Corona by Matt Rittman.
