Changelog for update GOG-8 (Mac) (added 16 November 2015):

- We've updated the Mac installers for each language for Planescape: Torment to be compatible with Mac OS X 10.11 (El Capitan)
- This update means that disabling the System Integrity Protection feature is no longer required.

I just bought this game and it's not working on Mac with El Capitan. The app is not launching, I don't have any error message, it just appears on the dock but nothing launches.

Hmm, might be the same problem as BG1 had. If so, manual fix if you are so inclined, but send in a support ticket either way.

Changelog for update GOG-9 (Mac) (added 30 November 2015):

- We've updated the Mac installers for Planescape: Torment in order to fix a conflict between the Mac printer driver and the Wineskin wrapper used to make Planescape: Torment Mac compatible.

I downloaded the new version but nothing changes. The game still doesn't launch.

Changelog for update GOG-8 (Linux) (added 19 May 2016):

- The Linux version of Planescape: Torment has been updated with a new Wine wrapper by our Linux team
- New: Updated compatibility with Ubuntu 16.04 and other Linux distributions (you will need to install your distribution's Wine package using the package manager in order to play)
- New: Better Wine prefix configuration and management
- New: Support for running custom commands and .exes in the Wine prefix (great for installing mods!)
- Fixed: Multi-monitor support (non-primary screens will be automatically disabled when the game starts and restored afterwards)
- Fixed: Better support for resolution changing

Edit: No real changes, so I deleted the post.

Changelog for update GOG-13 (Mac) (added 05 August 2016):

- Fixed an issue with saves in the OSX version not being written in the proper place and, thus, resulting in what could be called a "lost saves" issue.

Changelog for Update GOG-14 (Mac) (added 07 October 2016):

- Fixed an issue with the Mac version of Planescape: Torment where the save files would be moved every time the game was launched.

** The Windows and Linux versions were not affected by this bug **

On Macbook Pro Retina, 10.10.5, this game always boost the CPU temperature above 90 degree, please fix this issue in next version. Many thanks.

Please write to support. I don't work for GOG, I just post the changelogs, so everybody can see them.

Changelog for update 1.01 (A) (added 22 March 2017):
