This is cause by the chipset is not supported for D3 that’s why you are getting the blackscreen problem (mostly for apple macintosh)

so to avoid this error make sure you already see diablo 3 video card list and diablo 3 unsuppported video cards

but if you alredy get the black screen error, there’s a workaround to fix it :) though it’s not work for all players, have a try and good luck !

1. You’re going to have to show hidden files/folders, I used Onyx.
2. Go to your home directory (i.e. your name), then find the grayed out folder Library (it’s normally hidden).
or you can try this : in Finder Go to Go Menu at top of screen -> Go to Folder
Type in ~/Library/
3. Traverse to Application Support > Blizzard > Diablo III
4. Open D3Prefs.txt with your text editor and follow the same steps as the PC stuff:
Change:
– DisableTrilinearFiltering “1” (from 0 to 1)
– HardwareClass “1” (from 0 to 1)
Save the file and close it.
5. The one last thing I had to do was play it in windowed mode:
Added Change (in D3Prefs.txt):
– DisplayModeWindowMode “1” (from 0 to 1)
Save the file and close it.

This should prevent the black screen and initialize the first cut scene, you can proceed to watch it, or escape out of it and then you’ll be presented with the login screen for D3. As long as you play in windowed mode, you should be able to play if you were running into the black screen.

If you are unable to play Diablo III due to an “Unsupported graphics card error”, I do have a work-around. But before you do anything, please understand that your GPU is unsupported for a reason. Usually this is because of the absolutely mediocre performance it will get even at lowest settings.
Chances are your performance will be so bad that the game will simply not be playable. That being said, there is really no harm in trying out this work-around. Just understand that this is not a *fix* but rather a *work-around* and your performance will likely be awful no matter what. There is nothing Blizzard can do to *fix* this because there is simply nothing for them to *fix*.

Inside the folder libraries/documents/diablo III there is a file named “d3prefs.txt”. Open it. (There are other places it could be. For example, C:\Users\*YOUR USERNAME*\Documents\Diablo III … just use Windows search to find d3prefs.txt )

Change:
– DisableTrilinearFiltering “1” (from 0 to 1)
– HardwareClass “1” (from 0 to 1)

Save the file and close it.
When you launch the game, you will still get the same “Unsupported graphics card” error that pops up. Press esc and the game will load.
