Everything looks normal & acceptable except Picture 6.pdf. That looks hazardous & I'm not surprised you're having problems. You need to free up space on your system OS. By the sounds of it you only have one HDD. Free up space ... I'm surprised it doesn't also affect Photoshop because it uses a lot of VM by nature. What you failed to show in one of your 1st 2 images is how much virtual memory (VM) you're using. You missed that column out. But the same applies ... all OSX programs use VM & you must thus have at least a handful of free GB's. I'd recommend at least 10 GB of free disk space measured whilst there's no programs running on OSX.

If you respond I might not get back to you until tomorrow if that's ok with you.
