How To Install Optifine on a Mac

If it shows a Java version, you’re good to go!

Step 2: Download Optifine

1. Head to the Optifine Downloads Page.
2. Find the version of Optifine that matches your Minecraft version (usually the latest release is what you want).
3. Click on the “Download” button next to the desired version.

When you click on “Download” you will be served with an ad but you simply have to click on “Skip” in the top right corner of the screen to get rid of it and go to the download page.

When you try to open the download, macOS will warn you that Optifine cannot be opened because it is from an “unidentified developer”.

This simply means that it has been downloaded outside of the Mac App Store so has not been digitally signed by Apple.

Both Java and Optifine are still safe to install and if this is a concern, you can read more about this on Apple’s website.

To continue with the installation, you need to go to the Apple logo in the top left of your screen and select “System Settings” on Apple Silicon Macs or “System Preferences” on Intel Macs.

Go to “Privacy and Security” on the left hand side and scroll down the settings until you reach “Security” you’ll see the message “Optifine was blocked from use because it is not from an identified developer”.

Click on “Open Anyway” to install Optifine on your Mac.

Optifine will now install itself as a new profile in the Minecraft launcher.

Step 4: Launch Optifine in Minecraft

1. Open your Minecraft Launcher.
2. In the bottom left corner, click on the profile dropdown menu and select the “Optifine” profile.
3. Click “Play.”

Now, Minecraft will launch with Optifine enabled. You should notice improved performance, and if you want shaders, you can start adding them now.

You can also customize Optifine in the Options and Video settings.

You may find that reducing the number of chunks being rendered improves performance if you have any FPS or lag issues.

Step 5: (Optional) Install Shaders

To really take advantage of Optifine, consider adding shaders:

1. Download a shader pack (e.g., SEUS or BSL) from a trusted site.
2. Open Minecraft with the Optifine profile and go to “Options” > “Video Settings” > “Shaders.”
3. Click “Shaders Folder,” which will open a Finder window.
4. Drag and drop the downloaded shader pack into the folder.
5. Go back to Minecraft, select the shader pack, and click “Done.”
