@michaelcharles thank you so much for this guide. I was having the trouble trying to get Umbraco to work on my M1 Macbook air with the new mac os update. I have looked for hours and hours trying to find a solution, and was at the point of giving up for tonight, but then i stumpled upon your post :D

I would give you 1.000.000 likes and start if i could. Thank you sooooo much!!
