Mac (10000 programs)

Pros: Well-drawn locations. Well-hidden objects. Free trial levels. Good soundtrack.

Cons: Has its share of flaws. Trash is hard to recycle. Puzzles are a bit too simple. Skippable puzzles.

Pros: Results are in a text report. Alerts you to potentially dangerous app issues. Also lists invisible items. Results are in full sentences rather than data blocks.

Cons: Full version project has been abandoned. Manual/tutorial is very small. Non-developers will struggle to use this app. Requires backward compatibility to OS X 10.11 (El Capitan).
