BackgroundBack when I used a MacBook for Minecraft, on 1.7.10 Vanilla, Optifine, or Forge, I experienced a huge drop in frames (from 150+, often to <60) upon drawing back an enchanted bow. I searched for a fix to this issue for a while, but found nothing, only solutions for similar lag situations on 1.6.X. Finally, after posting on Badlion and several other forums, I found TheMasterCaver on Minecraft Forum helped me. Others especially on Macs and computers with integrated graphics seem to experience this lag, so I thought I would post a thorough guide to getting rid of that lag. This is not a problem texture packs as some may suggest.
I know of several older threads describing this problem, which are linked below. Perhaps someone with the issue would like to read other people's advice etc.

The Solution
To end this lag, you need to download two things: MagicLauncher and a modified bly.class. MagicLauncher makes it a lot easier to load the .class file, by eliminating the need for you to manually add it to the minecraft.jar.
Next you'll take add the class file to the Mods section in Magic Launcher.
1. Launch MagicLauncher
2. Click "Setup"

3. Ensure that the Minecraft profile you want to use is selected (probably Forge 1.7.10). The items in the red box should look similar to this.

4. Click "Add" and locate the bly.class. You may want to place it somewhere in your .minecraft folder (I made a new folder called MagicLauncher Mods), but don't put it in your "mods" folder because Forge won't run it without MagicLauncher. Find the file and click "Open."

5. Click "Advanced" and paste "-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true" into the "Parameters" box. This is telling Minecraft to ignore that the Minecraft.jar has been modified.

6. Click "Okay" below, enter your Minecraft username and password and click "Login." Minecraft should launch and you shouldn't lag when drawing an enchanted bow.
Hope this helps some people out, I know that issues like this can be very frustrating especially when dedicated forum searching is of no avail. I'm happy to help via the forums here or even better, on TS which I think can be faster for troubleshooting.
Cheers.

So, what i found is a download that combined both bettersprinting mod and optifine into one mod, so i can use that instead of forge.
But, i couldn't add any mods like armorstatus HUD and stuff like that, but now i can :D

That is not funny in any way, it is actually rather immature and I find it disappointing to see comments like that.

I agree, the prevalence of homophobic comments on Badlion is disappointing.

Was talking about the "closet homosexual" part rather than the comment that you pointed out… Also I am from Finland and that is even more offensive now. Stop.
