PCSX2 can't open?

[runthezazamarket]

I'm new to using Playstation emulators specifically on Mac. I recently found about PCSX2 on Mac and wanted to download it and have fun reliving my childhood playing Gran Turismo 4 and PES 2006. I downloaded the most recent verison, nightly version, v.2.0.3. Downloaded and unzipped the BIOS files, but when I try to open the appplication, it shows me the message "The application 'PCSX2-v2.0.3' can't be opened." Don't know if its just a hardware issue with my Macbook or if I did something wrong when unzipping the download file for PCSX2. Any feedback would be more than enough help. Thanks Lads!

Using a BIOS file with PCSX2 which you have downloaded from the internet or from a PS2 console you do not own is illegal. You must own the console the BIOS file came from (even if it's broken) to be legal.
