Shaders give super low fps on macs

I have a MacBook Air (M1, 2020) Apple M1 chip 8GB of memory Built-in Retina Display 13.3-inch (2560 × 1600) and when I use makeup ultra fast or chopapaic13 toaster shaders, I only get 20-30 fps when I get 150-160 normally. Is there a way to fix this?...

Health, hunger and some UI elements dissapear when shaders are on

Worked fine yesterday, today I tried installing Better Combat and while it works fine it would cause the ui to blip out even without shaders Got rid of it, but I am assuming that the problem is still persisting because of something it changed? I also removed a config file and additional library the mod downloaded but no dice...

White Border Fog with Sildurs Enhanced Default Shaders

I started encountering a white border fog when using Sildur's Enhanced Default (Fancy) Shaders (v1.16 as well as v1.171) in versions above 1.20. In addition to that my hitboxes also started rendering full white instead of being red at the eye height for example but weirdly the hitboxes render their colour correctly if I'm under water. I do not encounter those two bugs on 1.19.4. The first screenshot shows how the border of the chunks should look like (taken in 1.19.4) and the second screenshot shows the white border chunks. (taken in 1.21 but also experienced in 1.20 and all subversions) Does anyone know a solution to not have my border chunks white like that but "normal" like shown in the 1.19.4 screenshot?...

Player texture error in inventory 1.21

When I load the shader there is a small error in the player model, for example the tool in the hand and the elytra do not appear, they are invisible. This remains even after disabling the shader. It is only solved when I restart the game with the shader disabled. - iris-1.7.1+mc1.21 - sodium-fabric-0.5.9+mc1.21...
Solution:
fix coming with 1.7.2

iris shader setup not working

hey, sorry in advance for a few mistakes in my english. Im on windows 11. I have tried to install the Iris shaders with curseforge as well as with the iris shader website. Unfortunatly once downloaded it doesnt have some sort of installer or setup instead it downloads a jar file called "iris-1.7.1+mc1.20.6" with a size of 2 mb. If i click on it it just takes me back to download the same file from the browser. thanks a lot in advance....
Solution:
there is no setup if you use curseforge. Just install it and sodium through the curseforge launcher and then launch the game (you need the fabric mod loader installed on your modpack)

Shader packs not detecting

I have installed both sodium and lithium with the game working fine (1.21 Java Mac). I then installed the iris version which comes with sodium. But when I load into the game there is no where for me to view or even download shader packs. I have attached a view of my mods folder within minecraft, and also tried moving the "shaderpacks folder" in the regular minecraft folder, the mods folder, and the resource pack folder but nothing has worked. I have also attached a view of my game to show the problem in game....
