The old .vmoptions file is located here:
/Users/patmyron/Library/Application Support/JetBrains/Toolbox/apps/IDEA-C/ch-0/172.4343.14/IntelliJ IDEA CE.app/Contents/bin/idea.vmoptions
After updating through JetBrains toolbox, the new .vmoptions file is here:
/Users/patmyron/Library/Application Support/JetBrains/Toolbox/apps/IDEA-C/ch-0/173.4127.27/IntelliJ IDEA CE.app/Contents/bin/idea.vmoptions
It is tedious to remember and manually edit the new .vmoptions file after every update because JetBrains does not automatically inherit your edited settings from the old to the new .vmoptions file.
Is there any way to automatically sync your settings from your old .vmoptions file to your new .vmoptions file after every update?
See the FAQ. You just don't edit this file inside the install location, but in the config directory using
Help| Edit Custom VM Options.
