Make sure your Xbox and your Mac are on the same network (WiFi is fine, wired is faster)
Create a new 'server'
Type in your Xbox's IP address into the address field
Logon type: Normal

Depending on how you have your Xbox setup (using an internal HDD to store games or External HDD), it will depend on where you add them.
For storing games on the internal HDD: Put them in Hdd1: (in their own folder, like My Games or something like that)
External HDD will depend on how many USB devices you have, for me I only have 1 external HDD connected, so I use Usb0:
In Aurora, make sure your Games location is added to Scan Paths, and refresh the machine (Step 5 below or restart Xbox)
If the games are still not showing up:
Go down to Content
Navigate to the folder you created for your games. Use Y when the whole folder is highlighted. It should start Scanning Content, if not;
Press Scan Now
Wait for changes.
Hope this helps 👍
