I use Mac as well and encountered the same problem. While I did not find out how to change the view and obtain the interface shown in Lesson 1, I found an alternate way to access some features you're asking about.
For reference, above is the interface shown in Lesson 1 for adding an event in a SoundBank. Below is my interface on Version 2022.1.1, like yours.
As you can see, the New button is missing, along with the others. The way I created an Event in the Soundbank was by opening the Soundbanks tab in the Project Explorer. By right-clicking the Default Work Unit in the SoundBanks folder, you can create a Soundbank through the New Child option at the top of the menu. You can see my result under the User-Defined Soundbanks view, where I named the soundbank "Main."
As for the User/Project Soundbank Settings, there is an orange cog in the top right of my screenshot, within the Soundbank Manager View. You can access settings vital to the tutorial there.
I hope this helps! I will add, despite following the instructions in Lesson 1, I am having trouble getting sound to play when I run the game. I am pretty confident I followed the steps as intended, so I decided to go into Lesson 2 and pull up the project file that already has the needed configurations from Lesson 1. After running the game, there was still no sound! Below is an image of the capture log from my attempt and I will leave it here, in hopes that someone got further than me and has an answer for troubleshooting this? My selected media, the IceGem_Blast is apparently not available, yet plays back to me when I pull it up in the Actor-mixer Hierarchy, so I believe something may be wrong with the directory?
