Diablo 3 Mac Installation and Unsupported Video Fixes

I got my hands on an old iMac the other day and decided to install some games on it. So, I downloaded the Diablo 3 installer and tried to run it, but it just bounced in the dock for a while and then disappeared :(

The first thing I tried was to right-click on the installer and select 'Show Package Contents.' Then, under 'Contents' > 'MacOS,' you'll find the Diablo III Setup executable. Double-click it and you should see a Terminal window pop up and quickly disappear. You may not be able to see what has caused the problem, but it should have reported a permissions error ('Permission denied').

To fix this, open a Terminal window and navigate to the directory where you put your installer (for me it was Downloads; the easy way to get to it is to type 'cd ' [that's the letter c, the letter d and a space] and then drop the desired folder onto the Terminal window and hit 'enter') and type (include the quotes here):
sudo chmod -R 777 "Diablo III"
It will ask for your password and, once authenticated, it should fix your permissions issue.

At this point, you can try double-clicking on the installer and you should be in business.

If, however, it tells you that your video card is not supported (like me), you will have to do a little more work. No biggie.

Open a terminal and type:
nano ~/Library/"Application Support"/Blizzard/"Diablo III"/D3Prefs.txt
You should see a bunch of options, followed by values, like this:
Scroll down until you see the option 'DisableTrilinearFiltering' and change its value from '0' to '1,' then do the same thing for the option 'HardwareClass.'

It may not be required for everyone, but I also had to add an option, 'DisplayModeWindowMode,' with a value of "1."

Now, save and close by hitting Ctrl+x and then 'enter.'

You should be good to go :)

And, I assure you, performance *will not* be a problem (this is meant as a joke; of course performance will be a problem; it hardly runs, ffs).
