Do it correctly - to instal clear version of ioquake ???
I don’t understand what this mean by “clear version”? Do you mean you want to compile it yourself? Either way, there should be no need to remove ioquake3 in order to install a new version, but if you really want to do so you can put the ioquake3 folder in the trash can and also remove the user folder
I don’t recommend doing either of those steps, there should be no need.
No. I just want to remove quake from pc. Then install it again. Thanks for answer but some quake files missing in osx while I put main folder to trash. I’m not expert in osx how to use it perfectly.
