Mac OSX / Linux :
You can't open the .Pak file, so here a .zip version of the .Pak : http://www.managames.com/download.php?TE2013.pak.zip
It contains all the files from the .pak, except the few ones non-editable ; you can copy all of them in <TennisElbow2013/Mods/MyMod> (you have to create the "MyMod" folder).
It contains the files from v1.0d Build 109 ; it may be partly outdated if a new version is released. Delete the file "Menu\BuildMac.Txt" to avoid "Invalid/Corrupt Data" message with any newer version.
Anyway, you should be able to install all the Mods created, either on Windows or Mac OSX or Linux, as there's almost no difference in the game engine between the 3 versions.
Although, you should have your Hard Drive File System set to "Case Insensitive". If it's on "Case Sensitive", it'll usually create a lot of problems as Modders create files without checking the case in file names. However, if the Mod you're trying to install only contain Pak files, just make their case matches the one of the official Pak files, ie : "Pak01.Pak" ; you can also do that for all files that are outside the Pak file in the original game (example : Players.ATP.Ini) ; but for all files contained within the Pak file in the original game, but bundled outside of any Pak file with a Mod, you won't have the possibility to know the correct case for each character in their names.
On Linux, it might be not possible to have the File System set to "Case Insensitive", so you're in for troubles...
Also if the Mod you want to install provides sub-folders, don't replace your existing sub-folders with the ones from the Mod (except specifically specified in its install instructions) ; merge them together instead (it's the default behaviour on Windows).
