Can you play Mass Effect Legendary Edition on a Mac?
Short answer: Likely to work, but not tested yet — Mass Effect Legendary Edition lists DirectX 11, which Grapple's DXMT layer translates to Metal. Try it on the Free plan and tell us how it went.
What we know
Steam lists Mass Effect Legendary Edition for Windows only. Its minimum requirements call for DirectX 11.
Grapple translates DirectX 10 and 11 to Metal — through Apple's D3DMetal or the open-source DXMT — so on paper this is a reasonable candidate. That's an expectation, not a result — we haven't tested it yet.
Steam notes that it requires a third-party account: EA Account.
Steam notes that EA online activation and EA's client software are required.
Grapple settings
Nothing verified yet. Where to start, based on its DirectX version (in the app, the same options are in the game's settings):
- DirectX 10/11: a new install is set to Automatic, which picks D3DMetal or DXMT for you. If the game won't start or renders wrongly, naming a layer is the usual next try:
grapple set Steam graphics dxmt - To see frame rates, turn on the Metal HUD:
