Not enough memory or storage space. Release some space in ~ Library.

Description

When a Mac is new, it run super smooth. When it used for program dev, two or three years later. It becomes hard to use. Filled with cache and unused files. I cleaned up these dirs: ~/Documents, ~/Downloads, ~/Desktop. But still hard to get more than 10 GB. Ok, let's check if we can release some space in ~/Library.

Dev env

• macOS 11.6 (Big Sur) x64
• Android Studio Bumblebee Patch 1
• Android SDK version 31
• Android Gradle Plugin: 7.0
• Gradle: 7.1.1
• Gradle JDK: 11

Tried approaches

• Remove unused java version.

  • echo $JAVA_HOME see what version currently in use.
  • cd ~/Library/Java/JavaVirtualMachines, then ls -halt or open ., and delete unused version.
  • cd ~/Library/PreferencePanes/Java, then ls -halt or open ., and delete unused version. (This maybe not exist.)
  • cd ~/Library/Internet\ Plug-Ins/Java, then ls -halt or open ., and delete unused version. (This maybe not exist.)
    => It works!'

• Remvoe unused Apple device emulators and data.

  • xcrun simctl list devices to list all emulators.
  • xcrun simctl delete unavailable to delete all unavailable emulators.
  • xcrun simctl erase all to wipe all emulators' data. (use carefully)
  • xcrun simctl help for further help.
  • sudo rm -r ~/Library/Developer/CoreSimulator/Caches/dyld/*/*/ to remove Apple cached files.
    => It works!'
