So, I was trying to play Karlson (on a 64 bit mac, with MacOS Catalina) and when I tried to open it, it just gave me a message saying "Karlson can't be opened" or something like that. I saw that it didn't list if the mac version was 64 bit or 32 bit, so I just assumed it was 32 bit. Am I wrong? Am I doing anything wrong? Is there something wrong with the game? Please, help me out.

PLEAS HELP ME OUT

HEY I JUST WROTE A WHOLE REPLY WITHG ALL THE INFO BUT THEN I ACCEDENTLY DELETED EVERYTHING SO IM JUST GO-ING TO GIVE THE ANSWER

it is only compatible with 32bit macs :(

go to the page of steam for this game and everything yall need to know is there (mac only)

You have to go to sytem preferences security and privacy then select general, from there you press the lock enter your password and make it so you can get games from online and then you can play it

This is an issue with unity I have also encountered.

it works fine with me

i think you need to use the "unarchiver" other than the default unarchiver tool 

Use unarchiver, when its extracted right click on the app and click open. DO NOT double click... 

Unarchiver can be found in App Store...

and in the website

Yeah I also have this issue. The game was built with 32bit so it cannot run on Catalina unfortunately.

It can! I have a catalina and am able to run it... use the Unarchiver...

give it executable permissions or something, worked for my friend
