There is no MS office for Mac there is MS word, Excel and Powerpoint, so seeing as your is cracked you loose nothing, not a penny.
Paintshop pro used to be available for Mac, it's probably a bit old in the tooth, what do you use it for? Photos? iPhoto is built into the MacOs and is hard to beat for an image app let alone one that is free. I have no idea what corel video studio is if it is to make videos then iMovie is is stunning. You have all kinds of built in software, CD/DVD burning, text editors, image viewers and manipulators. Tell me what you want to do and I will tell you if it is built in or not and what the software is that you would need to crack or god forbid, buy.
