Affected Macs: Macs with GeForce 320/330 and some other old Geforce VideoCards.

Symptom: All objects on screen are black.

Explanation: The blackness issue is a program bug. However it will be fixed soon. What is much more bad is that the game locks up after the fix.

Right now we're investigating the issue for OS X El Captain. The problem is that the issue was seemingly fixed in 10.11.0 but is still at large for 10.11.2

There is some good news:

OS X 10.9.5 is completely unaffected. We will disable all workarounds for it in the next release. You can do it right now manually by following instructions below.

Info: The workaround consumes a lot of GPU power and makes game much more slow on 10.10 and 10.11.

- Please navigate to your game folder and search in 'Resources' for VideoCardBugList.plist there open ShaderBasedClear section, find your video card (320/330/8600/9400) and set it to 'false' (when editing as text; if opened in Xcode, set it to 'NO')

This file is under Application Support, something like:
/Users/UserName/Library/Application Support/Steam/SteamApps/common/Divinity Original Sin Enhanced Edition/Divinity Original Sin Enhanced Edition.app/Contents/Resources

In the Steam library, right click Divinity: Original Sin Enhanced Edition, select Properties, switch to the Local Files tab and click on the 'Browse local Files...' button.
For GOG, in Galaxy select the game, click the More button, and in the Manage sub-menu, select Show Folder.

- Now run the game. It should work correctly (at least in 10.9.5).

What you can do to help?

Right now we need confirmation that:

OS X 10.9 with manual fix above works absolutely correct. With any gfx settings.

The original release of D:OS (not EE) works fine on El Captain at all for affected video cards.

OS X 10.10 status for those video cards.

I reiterate - the blackness is non issue. Lock ups - that's what is very bad. If you have only blackness try switching game around, start new game, tweak settings, etc. Then try above workaround.

Sampling and Apple bug reports.

After disabling workaround above and getting a lock up on El Captain you can really help everyone by collecting Sample and filing it with Apple

To get sampler output from the Activity Monitor:
1. Verify your Steam or GOG game cache (the latter if using the Galaxy client)
2. Launch Activity Monitor
3. Start the game and get into a freeze state
4. Now Alt-Tab back to Desktop and check Activity Monitor. What do you see? How much CPU does the game consume?
5. Double click on the Divinity - Original Sin Enhanced Edition process and press 'Sample' button. Wait until Sampler is finished
6. Save sample output using 'Save' button

The apple site is bugreport.apple.com. Be sure to provide Larian support mail as additional info (supportdos@larian.com).

And concluding all this: Sorry guys and gals, we will try, but this is definitely an Apple issue. We will be updating you with all the relevant info as we prepare blackness fix.

I'm running D:OS EE on 10.11.2. Haven't encountered the black items bug.

However, I do notice that whenever I read certain books the game will invariably crash. Particularly the ones I stole from the library in Cysel. XD

Having played the original game, it looks LOADS better in 4k. Thanks for this big addition Larian, and porting it to Mac.

Updated information about this issue has been posted in the topic Random game lock-ups on Macs with old Nvidia cards.

. It was only an issue on some older nvidia cards (GeForce 320, 330, 8600 and 9400).


For the book crash, please email supportdos@larian.com, with a brief description, your system specs, a crash report and a save where this happens.
To get system specs you can use the 'System Report' button from the 'About This Mac' Apple menu item or the 'System Information' app (in the utilities folder).

I have a MacBook Pro Mid 2010, 4 GB RAM, Geforce 320M running OS X 10.10.5. I can confirm everything you wrote above and in your random_game_lockups_on_macs_with_old_nvidia_cards post:
* without any changes, the main screen of the game only shows the sea, sky and flame of the torch in colour. Everything else is black.
* Setting ShaderBasedClear to false for "320" in VideoCardBugList.plist removes the blackness problem
* Disabling the shadows in the preferences locks up the game almost immediately on the main screen (regardless of whether the VideoCardBugList.plist change has been reverted)

I've collected a sysdiagnose "Divinity - Original Sin" and will file a bug report with Apple as requested (FWIW, it seems sysdiagnose has a bug when supplied with a process name that contains a space: it doesn't save the system profiler report in the generated directory). My normal gaming machine is an iMac Late 2013 model with a GeForce 750M (and OS X 10.9.5, though that doesn't matter given the card), so it doesn't really impact me. I never expected my MacBook to be able to run D:OS EE at all :)

Edit: It's filed as rdar://problem/24025807

Just got a reply from Apple stating that this should be fixed in macOS 10.12. I'm currently on holidays and have no broadband internet access, so I can't download that OS release to test it right now.

Good news: D:OS EE seems to work fine in the final release of macOS 10.12, and the issue with the game locking up on my mid-2010 MacBook Pro with a GeForce 320M when disabling the shadows in the graphics options has indeed been fixed! This is with v2.0.113.775 of D:OS EE, "ShaderBasedClear" set to false for the "320" key, and after disabling shadows in the game's video options. It also (still) starts fine on my late-2013 iMac with a GeForce GT 750M under 10.12.

I have not actually played the game to any extent though.

Glad to hear you still have a lead Mac programmer :) (no, I don't take this as an official confirmation that there will be a Mac version of D:OS2, but one can dream...)
