I can't see my character and entities, can you help?

SO i have played Starbound for a while now, but i have run into this bug that means i can't see anything but the ground, i can't see myself, others (like other online players and npcs and enemies) or things i have built, or other settlements, if you know how to fix this please tell me how (this was a steam discussion for the steam version, i just really want to fix my game! For images of the problem, visit my steam screenshots for Starbound, my account is: crumblycrumble)!

 

My "machine" is a iMac 21.5-inch, Mid 2010, with a Intel Core i 3, with 4 GB 1333 MHz DDR3, Graphics ATI Radeon HD 4670 256 MB ( i don't like mac).
Thanks for answering so quickly

 

I cannot as i had a fix that only briefly worked which was to game files, but i could send you all of the game's files, or just the storage files.

 

The game just started to work again, but i doubt for long.

 

it broke again here is a longer game session that is modded, sorry...

 

ok cool thanks!
