# El Capitan & Homebrew
|
|
|
|
Part of the OS X 10.11/El Capitan changes is something called [System Integrity Protection](https://en.wikipedia.org/wiki/System_Integrity_Protection) or "SIP".
|
|
|
|
SIP prevents you from writing to many system directories such as `/usr`, `/System` & `/bin`, regardless of whether or not you are root. The Apple keynote is [here](https://developer.apple.com/videos/wwdc/2015/?id=706) if you'd like to learn more. As noted in the keynote, Apple is leaving `/usr/local` open for developers to use, so Homebrew can still be used as expected.
|
|
|
|
One of the implications of SIP was that you could not simply create `/usr/local` if you had removed it. This issue was fixed with the `com.apple.pkg.SystemIntegrityProtectionConfig.14U2076` update.
|
|
|
|
**If you haven't installed Homebrew in `/usr/local` or another system-protected directory, this document does not apply to you.**
|
|
|
|
This is how to fix Homebrew on El Capitan if you see permission issues:
|
|
|
|
## If `/usr/local` exists already:
|
|
|
|
```bash
|
|
sudo chown -R $(whoami):admin /usr/local
|
|
```
|
|
|
|
## If `/usr/local` does not exist:
|
|
First, try to create `/usr/local` the normal way:
|
|
|
|
```bash
|
|
sudo mkdir /usr/local && sudo chflags norestricted /usr/local && sudo chown -R $(whoami):admin /usr/local
|
|
```
|
|
|
|
If you see permission issues instead try:
|
|
|
|
* Reboot into Recovery mode (Hold Cmd+R on boot) & access the Terminal.
|
|
* In that terminal run:
|
|
`csrutil disable`
|
|
* Reboot back into OS X
|
|
* Open your Terminal application and execute:
|
|
|
|
```bash
|
|
sudo mkdir /usr/local && sudo chflags norestricted /usr/local && sudo chown -R $(whoami):admin /usr/local
|
|
```
|
|
|
|
* Reboot back into Recovery Mode & access the Terminal again.
|
|
* In that terminal execute:
|
|
`csrutil enable`
|
|
* Reboot back into OS X & you'll be able to write to `/usr/local` & install Homebrew.
