"Application can't be opened." error on MAC!

Hello! I am running Unity 5 Personal Edition on Windows 8, and I built a OSX version of my game and then packed the a folder I created containing the .app file into a RAR package. Then I uploaded it to https://www.mega.co.nz/ and went onto my Mac, downloaded the file from there. Then when I tried to run the .app file, it gave error "Application can't be opened.". Nothing else, literally... Only that, no error signs like "-Error code 702". Nothing at all!

Imagine that 2.9 was the last version that worked on MAC. 3.0, 3.1 and 3.2 did not work properly on MAC neither, which makes me confused... Plaese tell me, am I doing something wrong?

 

I was planning on posting this question to "Platforms" subcategory, but I did not find OS X or I am just blind... Sorry if it's posted in wrong Forum

 

Open Console and check the system log. It'll tell you if it's a permissions problem or an actual crash/hang.

 

I realized that the game would not build on Windows platform neither, so then I deleted some packages that I realized were the sources of the error and now I'm trying to build it on mac again. If it does not work, I'll take your advice
Thank you very much!

BTW, your profile picture... I've seen enough you know what to know where that is going! Or... where it 'has been'. Get it?

Hahahahaha
Anyway, it turns out that was not the case :/ It works now to build and play on Windows but still not on MAC. I'll check out what you told me later on, once again thank you!
