About
The website text does not mention a Mac app or a product called "Monero Wallet," so it cannot provide a Mac-specific description. It only says that Monero wallets are available for a variety of platforms and contain everything you need to use Monero immediately, and that you can get the right wallet for you from the Downloads page.
The text also explains that a wallet is the first thing you need to use Monero. After installing a wallet, you need to acquire some XMR, which you can do by mining, working in exchange for Monero, or using an exchange to convert fiat money into XMR. Monero can be exchanged for goods, services, and other currencies privately and with very low fees.
For details on a specific Mac app, check the Downloads page or other official Monero resources, since the provided text does not cover them.
