OS X version[edit]

Modding the Wineskin version can be done by firstly installing the Windows version in a virtual machine, patching it and installing all desired modifications and then replacing the System Shock 2 installation within the Wineskin version with the custom version. If you are using the Steam version it may be necessary to deactivate Steam's "Keep up to date" function for this to work.

Issues fixed[edit]

Random crashing[edit]

Use SS2Tool[citation needed]

See SS2Tool.

Left-clicking or dragging does not work[edit]

Use SS2Tool[citation needed]

See SS2Tool.

Small game window or black screen[edit]

Edit cam_ext.cfg to disable multisampling[citation needed]
  1. Go to the installation folder.
  2. Open cam_ext.cfg using Notepad.
  3. Comment out and change multisampletype 8 to ;multisampletype 8
Enable SS2Tool Safe Mode[citation needed]
  1. Download and run the SS2Tool installer.
  2. At the Choose Components installation step, enable Safe Mode.
  3. Click Install and finish installing.

UI too small on high screen resolutions[edit]

Edit cam_ext.cfg to enable ui scaling[citation needed]
  1. Open cam_ext.cfg in Notepad or any other text editor.
  2. Uncomment the line ;d3d_disp_scaled_2d_overlay 64 by removing the semicolon.


If this does not fix the issue, you may try scaling the UI to arbitrary resolutions by re-commenting out the above line (add back in the semicolon), uncommenting the line ;d3d_disp_scaled_2d_overlay 640 480 and adjusting the 640 and the 480 to your desired resolution. However, this may cause the ui to become blurry/pixelated, so try the initial fix first.
