My gaming PC (which runs on Windows) has very limited bandwith: I can connect to the internet, but cannot download a game. However I do have a macbook with access to a network with unlimited bandwith. Is there any way I can download Steam games (for Windows) on my mac and then transfer them to the Windows PC?
Most multi-platform games share a large amount of data between platforms, even though the actual executable is different.
Let's look at Half-Life 2 and other Source games. They have lots of
*.gcf files inside the
Steam\steamapps folder. Those files contain all the multimedia assets (levels, audio, textures, 3D models...), and such data is identical to both Mac and Win versions. Thus, you can safely copy such files from your Mac Steam to your Windows Steam, saving you a few gigabytes of downloads. Then, the Windows Steam will still download Windows-only files, but they are quite small, maybe less then 100MB.
It also works the other way around: copying files from Windows to Mac.
What I've described should also work on most steamplay titles, that are available on Steam for Mac and Windows. (but you might need to copy files from subdirectories inside
However, if you want to download a Windows-only game, then you might need to run the Windows version of Steam. You may achieve that using one of the many virtualization options (VMware, VirtualBox, Parallels), or even try your luck running Steam under Wine (but that might be too buggy).
Valve's SteamCMD does just that.
- Download and unpack steamcmd.
- Cast this spell to log in, set a game directory and download the game. Fill in
<your login>, or replace with "anonymous" if you're downloading a free game. Replace a
740with your app id - you can see the app id in game URL on
./steamcmd.sh +@sSteamCmdForcePlatformType windows +login <your login> +force_install_dir ../csgo_ds +app_update 740 validate +quit
I'm not sure, but you might be able to do a back up of the games on the Mac and then transfer them to the PC. Obviously the executables are different between the Mac and PC, so I'm hesitant to suggest this. The sure fire way would be to use boot camp or parallels on the Mac to download the Windows versions, then back everything up (in the menu, Steam->Backup and Restore Games...) and transfer them via external harddrive.
