Here are this weekend’s Mac riddles to entertain you through family time, shopping and recreation.

1: Two credentials or 762 should be superseded by passkeys.

2: Notably from Autodesk but once by Claris, it’s 3,245.

3: From the Mac II until replaced by USB, 2,779 was quite enough.

To help you cross-check your solutions, or confuse you further, there’s a common factor between them.

I’ll post my solutions first thing on Monday morning.

Please don’t post your solutions as comments here: it spoils it for others.
