I am using a 2019 MacBook Pro and have been a long-time user of IntelliJ IDEA. However, the 2023 version is extremely slow when attempting to perform any task. I have tried increasing the heap size to 4GB and 8GB, but IntelliJ still uses more than 1000% of the CPU and runs out of memory. After reverting back to version 2022.3.3, it runs smoothly with a 2GB heap size, and I can quickly close project windows and type smoothly in the terminal while a project window is starting.

Is there anything I can do to improve the performance of the newer version? I don't want to remain on 2022 indefinitely. Since the issue is unclear, I am unsure how to look for relevant YouTrack tickets.

  • Do you have an external monitor attached? I have seen recent issues with several other Jetbrains products when I have a high def monitor plugged into my M2 Mackbook. Just wondering if there is a similar problem with x86 macs. – Code-Apprentice Jun 17 '23 at 21:26
  • Performance problems could be very specific depending on each case. I'd recommend you contact JetBrains support at at https://intellij-support.jetbrains.com/hc/en-us/requests/new and provide diagnostic data as per https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems – Egor Klepikov Jun 19 '23 at 06:59
  • Same issue on my mac book pro 2019, I tried both Intellij IDEA 2023.1.4 and 2023.2. When it run some tasks (e.g. building or indexing) my mac is very slow and I almost cannot do anything. But when I switch back to Intellij 2022.3.2, everything goes well. – csujiabin Aug 01 '23 at 10:18

Please Tell the detailed version number of the IntelliJ IDEA.

I'm work fine both in M1 and Intel MacBook Pro.

IntelliJ IDEA 2023.1 Preview -> Build: 231.8109.175

Each version of IntelliJ IDEA has macOs dmg for Intel and macOs Apple Silicon dmg for the M1. Make sure do not install the wrong dmg.
