IntelliJ IDEA CE cannot start due to Error occurred during initialization of VM


Hi there,

I cannot start IntelliJ IDEA CE. I am using MacOS 10.15

I tried /Applications/IntelliJ\ IDEA\, and got message:

2021-01-12 14:31:20.730 idea[40724:295236] Value of IDEA_VM_OPTIONS is (null)
2021-01-12 14:31:20.730 idea[40724:295236] Processing VMOptions file at /Users/my_user_name/Library/Application Support/JetBrains/IdeaIC2020.1/idea.vmoptions
2021-01-12 14:31:20.731 idea[40724:295236] Done
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Error occurred during initialization of VM

JVMCI Compiler does not support selected GC: concurrent mark sweep gc


I also opened the /Library/Application Support/JetBrains/IdeaIC2020.1/idea.vmoptions, below is the content:



How do I fix this? Thank you!

It looks like you override IDE runtime with some custom JDK. Try switching back to the bundled JetBrains Runtime, see .

If there is idea.jdk file in /Library/Application Support/JetBrains/IdeaIC2020.1/ directory, delete it.
