Maybe I'm just dumb as all bloody heck, but I simply can't get Optifine+Forge installation to work on 1.18.1
Can someone please offer me the absolute 'for dummies' guide? For the current files?
I've tried every method listed, and I've been trying for literally three hours now and absolutely nothing seems to be working, not even with magic launcher - I don't HAVE an Optifine ZIP so I tried adding the JAR but it doesn't work.
Most recent method I've tried is the complex installation method, it says to;
Copy the files from the OptiFine ZIP file to "Forge9.10.X.Y.jar" as usual (you can use the 1.5.2 instructions for this) and remove the META-INF folder from "Forge9.10.X.Y.jar".
But I don't have a ZIP, so I thought perhaps it wants the files from inside the JAR, but what does AS USUAL mean? Which files? Just the base directory files? Or all the files AND folders? I've never used Optifine, and the 1.5.2 instructions that are here don't seem to say anything about this?

I don't know what guide you're using, but that sounds like it's at least 8 years outdated.
In MC 1.18.1 installing Forge like normal and then placing the Optifine jar in the `.minecraft/mods/` folder like you would any normal Forge mod seemed to work fine for me.

I love this mod but can't install Java on my work computer. How can I install Optifine? Even when I ask "how to install optifine without Java?" I am told to download Java. Why can't it be in a simple zip format like other texture or resource packs?

Use a custom Launcher like MultiMC or Technic Launcher
With Technic Launcher, search for a "Clean Forge" modpack and install it

Typically, you would need a standalone version of Java installed on your PC in order to install Optifine. In fact, even Minecraft needs Java, but nowadays, a Java distribution is included in the Minecraft Launcher.
An alternative way of installing Optifine used to be to install it as a Forge mod by adding it to the mods folder of a Minecraft instance that already has MC Forge installed. However, in order to install Forge, you may also need Java. :/
It could be that the .exe (Windows) or the MAC executable downloads of MC Forge (files.minecraftforge.net) do work without a Java installation, though. I do not know. I always used the executable (Java) jar files myself.
Optifine is installed/inserted in the Minecraft instance and not as a separate program elsewhere on your PC. So what you could do is copy the Minecraft files including Optifine installation from a PC with Java to your PC where you cannot install Java using a USB drive or, I don't know, by mailing it to your work e-mail?
TL;DR:
1. Try the .exe download of MC Forge.
2. Copy MC in its entirety over from a PC where you CAN install Optifine.

It is possible to use the bundled runtime that comes with the launcher to run any Java application (or most, depending on whether the bundled runtime is a "full" Java instalaltion):
Note that you don't necessarily need to place the installer in the indicated folder; I've successfully used a batch file to directly call the java.exe file; for example:
@echo off
"C:\Program Files (x86)\Minecraft\runtime\jre-x64\bin\java.exe" -jar CaveFinder.jar range 1536
pause
(the "pause" at the end also keeps the window open in the case of any errors so you can actually see them)
One potential issue is that the runtime may be a newer version of java, which can cause issues; mine hasn't been updated in years since I've never run any newer versions and is still Java 8 update 51 (the launcher might also store multiple runtimes due to issues with older versions/launchwrappers on Java 9+).
Also, using Forge just to load Optifine is counter-productive if you are using it for performance; it will easily negate any performance gains due to all the bloat it adds, as claimed by FoamFix (Forge adds a lot of "hooks" into the code that allow mods to interact with it without modifying it, even Optifine is less than optimal because it adds its own for compatibility):
Porting it to vanilla would have very few benefits, as vanilla by itself is more efficient than even Forge+FoamFix.
Hey! um... i have a question. can you update the installation guide to include MultiMC for the installation instruction, because i just dropped it in my mods hoping it'll work, asking myself if i did it right. so can you update the thing. Thanks!
Can someone help me with this weird issue. using optifine G7 with a modified Create above and Beyond modpack.
If you are using Overwolf, remove it
If not, check for CPU and GPU driver updates
Roger that sir. Thanks!

Thank you for Optifine, I've been using it for 6-8 years and it's always worked perfectly!
OptiFine crashed with latest ATM7 (all the mods 7) pack version 0.4.10. Anyone else has this issue?
I'm using Forge 40.1.31 and MC 1.18.2
Try an older ATM 7 modpack build
https://www.curseforge.com/minecraft/modpacks/all-the-mods-7/files/3757592
I can't, I'm playing on a server. But I know older build works.
The latest build is using a newer Forge build - Optifine requires an older build

Use a custom Launcher like MultiMC or Technic Launcher
With Technic Launcher, search for a "Clean Forge" modpack and install it
Then add Optifine as jar into the mods-folder at
C:\Users\NAME\AppData\Roaming\.technic\modpacks\MODPACK\mods\
With MultiMC you can create a Forge profile without installing Forge by yourself - also add Optifine to your mods-folder

I believe that both of those launchers need a Java installation to run Minecraft, though.

EDIT: im not using forge, fabric, quilt, etc.
Does any one know why i can't sprint with optifine enabled It's not just one version its when ever i use it
