I have a similar problem. Running MacOS 10.13.6 (High Sierra). Running D2 LoD. Some additional points:
- Game ran without problems in pure single player mode.
- Problems began after “Open Battlenet” button initiated patching
- Game now normally requires 4-6 launches before it will run.
- Once running it doesn’t crash,
- Launch crashes are of two distinct types:
Freezes, eventually requiring a forced quit. Gives Apple dialog for reporting.
Plain crash, giving Bizzard Error dialog for report to Blizz. - Same result after reinstalling (multiple times)
- Same result installing on another Mac
I had to buy a new CD key, because the one purchased years ago was “assigned to another BN user” for some unknowable reason. Needless to say, I’m not thrilled about having to buy a new copy of a game I already owned, only to have it not run properly.
