Marc Solitaire

Is it a full port? Is it Apple Silicon native? Does it use Quartz/Mac menus?
Yes it's a full working port of Aisleriot Solitaire. Yes it is Apple Silicon native. Yes it uses Quartz and Mac menus.

Why is it called Marc Solitaire? Is it disappointing being a 30-something who can't spell their own name?
Marc is a quasi-acronym for Mark's AisleRiot Clone. And yes. 😞

Is it sandboxed? Why is macOS refusing to run sandboxed apps?
Yes and I don't know. No entitlements or external file access are required.

What is the default game?
It's Klondike single-card-draw with two redeals. You'll need to switch on the status bar to see how many redeals/cards you have left.

Will it be released for other platforms?
No. Other platforms can download Aisleriot Solitaire direct. At some point, a version for Intel Macs may be released.

Why release for a platform used by only a few percent of gamers?
Precisely because there are so few games for Apple Silicon - owing largely to lack of Unity support.

What are your future hopes for Marc Solitaire?

There'll be a pause in development now but ideally:

• Proper end-of-game detection for Klondike and Freecell
• Auto-piling to finish off Klondike games for the user
• Hints that show the card to move not just display a dialog
• Restoration of the many languages Aisleriot supports
