"How to Optimize IntelliJ IDEA Performance on Mac Air M1: Troubleshooting Guide"


"I'm using a Mac Air M1 and attempting to run IntelliJ IDEA Ultimate. Despite my efforts, I'm encountering performance issues that are impeding my workflow. I've meticulously followed several steps to address the problem, including:

  1. Rebooting my Mac.
  2. Invalidating Caches and restarting the IDE.
  3. Reinstalling IntelliJ.
  4. Deleting the 'Caches' and 'Application Support/JetBrains' directories, followed by a fresh IDE installation.
  5. Verifying that I'm using the default Java Runtime version.
  6. Ensuring I'm using the ARM version of the IDE.
  7. Disabling Antialiasing.
  8. Closing resource-intensive apps like Google Chrome.
  9. Installing the Atom Material Icons plugin.
  10. Downloading prebuilt shared indexes.
  11. Modifying the .vmoptions file to include: -Dsun.java2d.opengl=true -Dsun.java2d.opengl.fbobject=false
  12. Disabling smooth scrolling.
  13. Operating on the Mac without an external display and connected to a power source.

Despite all these efforts, my IntelliJ IDEA 2022.1 (Ultimate Edition) continues to exhibit performance issues on macOS Monterey Version 12.1. My Mac Air M1 boasts 8 GB of RAM, 8 cores, and runs on the Apple M1 chip.
