To make this change persist after restart on MacOS
Many Mac users find this is forgotten and needs to be re-applied after any restart. This may happen if MacOS has applied the quarantine attribute to VS Code, which the OS uses for the "Are you sure?" notice applied on first using apps downloaded from the internet.
To check if this attribute is applied, look for com.apple.quarantine in the list returned by this command (changing the path if that's not where you installed it):
xattr "/Applications/Visual Studio Code.app"
If that does return com.apple.quarantine, you can remove the attribute using the same command with the -d flag (alongside -r to recursively remove it from all contained files and sudo to allow the change):
sudo xattr -r -d com.apple.quarantine "/Applications/Visual Studio Code.app"
...then do Shell Command : Install code in PATH as above after the attribute has been removed, and it should persist after restart.

$ source ~/.bashrc. I would suggest you to source the.bashrcfrom~/.bash_profile. - sarbbottamOS Xyou would generally add that to your~/.bash_profile— not~/.bashrcthen restartTerminal.appor source it like mentioned. - l'L'l
