Hi, new to PICO-8. I installed it on my Mac and it runs fine. But I downloaded some carts from Lexaloffle and when I copy the pathname to one and type "load PATHNAME" I receive the "Could not load" message. It doesn't matter which folder the cart is in and I've tried it with two carts that my friend got working. I checked that PICO-8 has read/write permissions. What could be going wrong?

Thanks
