Q:

Will the version of Diablo 2 included with the Collectors Edition of Diablo 3 run on modern Mac OS X?

The collectors Edition of Diablo 3 includes a 4GB USB drive preloaded with Diablo 2 and Lord of Destruction.
Will this version of the game run on a modern Intel Mac running OS X 10.7 without modifications, virtualisation or other third party software?
I have read that Blizzard stopped supporting Diablo 2 on the Mac after Apple removed Rosetta from the OS, but does this also mean they would send out copies of Diablo 2 that won't run on a Mac?

A:

As of 2017, yes, Blizzard supports D2 on the latest macOS (10.12).
At the time of release, no, the included Diablo II + LoD did not run on OS X Lion (10.7). The soulstone drive edition was no different than Blizzard's latest digital download, which worked with Mac OS 10.3.9 through 10.6 Snow Leopard (and Windows 2000 through Windows 7) but not 10.7 Lion.1 They also had no immediate plans to support it.2 3
So, yes, the Collector's Edition USB soulstone shipped without modern support for D2, though it runs just fine in Parallels and Boot Camp on a MacBook Air, and now runs on the latest Macs.
