I'd be happy to help you with downloading the Aegis Descent game for Mac.

As per the provided text, it seems that you need to download a macOS disk image (.dmg) file, which can be done by using the following links. Once downloaded, you'll need to open the .dmg file and extract the package (.pkg) file within. Then, follow the on-screen instructions to install the macOS installer into your Applications folder.

Additionally, it's worth noting that AGEIA PhysX software is required to improve the performance of Nvidia graphics cards, but it seems that this software might not be necessary for downloading Aegis Descent.

If you're looking for more information about Aegis Descent or its system requirements, I can provide you with some additional details. According to Steam charts and data, the game requires a minimum of:

* macOS High Sierra (10.13) or later

* Intel Core i5-2400 3.1 GHz processor

* 8 GB RAM

* NVIDIA GeForce GTX 660 or AMD Radeon HD 7870 (2GB VRAM)

* Free disk space: 20 GB

Before downloading the game, make sure you have a stable internet connection and sufficient data storage available on your computer or external drive.

Please let me know if there's anything else I can help you with!
