hello , you can use both app the new crossover one and keep your old one in your application folder, no problem..
Did you answer my question or other person's? Can you explain in more detail because i didn't really understand what you said
did you try the new crossover update (16.2.5)? its ok with steam.
if so, you can use older version , because in mac os, you can keep older version and newer of the same soft , by example :
crossover 16.2.5 etc... when you copy your app in the applications folder, osx will ask you if u wanna keep the older one or not, so you can have a lot of crossover version in applications folder ! :)
osx will called like : crossover , crossover 2 etc..
crossover will ask you to update bottle everytime you switch between different version, but it is a up and down system, so you dont have to be affraid about it
sorry english is not my native langage...
