Use this one while it still works:
Some PDFs can be viewed, but not copied or printed, and I find this annoying, and it makes it harder for me to use the files. This recent hint gives one solution to such restrictions. Here is another much simpler way:
– Open the restricted PDF in ColorSync.
– Choose File: Save as, and name it whatever you like.
– Open the saved file in Adobe Reader or Preview and enjoy!
– The original Preview version 1.0 disregarded all such limitations … looks like ColorSync does, too!
I’ll have the link to Preview 1.0 soon 🙂[via]
