## macOS
|
||
|
|
||
|
In macOS, Bash read `~/.bash_profile` not `~/.bashrc`, so edit `~/.bash_profile`:
|
||
|
|
||
|
```bash
|
||
|
[[ -f ~/.bashrc ]] && \
|
||
|
source ~/.bashrc
|
||
|
```
|
||
|
|
||
|
To use latest Bash, install `bash` with Homebrew.
|
||
|
Then append to `/etc/shells`:
|
||
|
|
||
|
```txt
|
||
|
/usr/local/bin/bash
|
||
|
```
|
||
|
|
||
|
Set default shell
|
||
|
|
||
|
```
|
||
|
chsh -s /usr/local/bin/bash
|
||
|
```
