Replying to Help an idiot download programs

I'm old and have never stolen programs from the interwebz. I'm looking for Photoshop and Illustrator for Mac Sierra 10.12.5. No idea what I'm doing but I do have Vuze.

Can anyone post a link to something that works straightforward on pirate bay or where ever you get stuff these days? Or, how do you know if they are good? Reading the tips/comments on whether they are good or not throws me for a loop.

Much appreciated
