Yes I had to install Sequoia early for work! It's not like I don't have other machines to work with so it's not a big deal, nothing urgent and can also dev locally with nginx which runs fine, but I'm glad it brought me to Indigo. I like to keep up-to-date with all the different local server solutions because I had never found one that scratched all my itches - having Apache to debug htaccess and other custom Apache stuff locally, among others - but y'all flew under the radar so much, I'm surprised you've been around in beta for so long without me noticing!
And tbf, Apache seems to be the only thing buggy right now in Sequoia, everything else is super stable and no other app has failed on me - except Safari that has some rendering issues in some websites, but that's also to be expected.
Sparkktv might be onto something about the permissions to run in the background because I can confirm that Mamp Pro does work over here too and having that "running in the background" permission in the settings is the only thing that's different I can notice.
