Full Audio Crash

I was installing mods when after the mods were installed, the audio cracked completely. Not only Tmod, but also system audio, youtube, discord and any other application. I already validated that it is not connected to another audio port (because there isn't, it's only to my headphones) and I can't find information on how to solve it.

tModLoader runs terribly on new M4 MBA

tModLoader is running awfully slow (low framerates, literal slowdown - most basic you can get) on my M4 13" MacBook Air (base mdoel). I think this is due to the fact that gamemode doesn't get enabled because macOS doesn't recognise tModLoader as a game. I tried some funky terminal commands but to no avail. base terraria runs fine, especially when "Game Mode" gets enabled, which is when macOS detects a game being played in full screen (does not recognise tMod as stated). running very few mods (just Overhaul and Calamity) - this performance is comparable to my last PC, in which I could only run 1.4.4 tMod in windowed, but I can't even do that here as nothing changes, and the way fullscreen optimisations work on mac is weird (mac's fullscreen directly conflicts with Terraria's window settings)...

Does anybody know what happened.. 😭

I was playing modded with two people and our Underworld didn't generate properly I guess? I tested in solo and it was fine, but whenever we load up on multi this is what is there and what happens. Do I just need to make a new world? I've literally never seen this before....

What does F8 mean in Terraria/Tmoadloader and what can we do to solve our issue with server lag?

Hi, Im new in this server and dont know if this is the correct way. If it is, please delete it and tell me where to head. Me and some friends are playing Tmodloader and are playing on a world loaded on a server. It is a modded world. sometimes we experience major lag and we can't do anything. we discovered when we press F8 in game, we get something that looks like a perfomance list (according to our own internet searches). We noticed that Magic storage takes a lot but also number 55 in the list. We have absolutely 0 clue what the list means and what number 55 in the list is. Is there maybe someone that can help us more along? We are playing with 5 people and 3 of us are also studying coding but we can't seem to find an issue to our problem....
