Add support for macOS 10.13 High Sierra

[ktheory]

This script on High Sierra works for me.

As for dropping legacy support, I’m inclined to do that whenever it
becomes a support burden.

• Removes an old workaround from Aug 2016
• Skips /usr/local ownership check on new systems. I don't think we need this anymore since everything else under /usr/local is owned by the user.

I remember the /usr/local bug biting a bunch of people setting up machines around that time period: #43

Are we sure that's resolved now?

Are we sure that's resolved now?

@willmanduffy Thanks! Nope; it's not resolved. Gonna take another pass.

Note that sudo chown -R $(whoami) /usr/local failed after upgrading to macOS 10.13 with an "Operation not permitted" error. I presume the upgrade reset SIP file system protection.

The next best fix that comes to mind is to install node with a different $N_PREFIX, like $HOME/.n (so node versions are installed in a user-writeable location by default. Or we can have this script just make an chown the directory n expects: sudo mkdir -p /usr/local/n; sudo chown $(whoami) /usr/local/n

Per Homebrew/brew#3228 there is a different command to change ownership now. Because SIP blocks changing /usr/local but it doesn't block the subdirectories under it.

sudo chown -R $(whoami) $(brew --prefix)/*

[laptop] Get bin/dev working on High Sierra, both fresh installs and upgrades

[jonathan-dejong]

Hi!

Just booted up a brand new Macbook Pro and brew is one of the first thing I've attempted to install after first updating it to High Sierra etc.
Here is what I had to do to make brew work as expected (so far, will update with more if more is required) from a completely fresh install.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile
sudo mkdir /usr/local/Cellar
sudo mkdir /usr/local/opt
sudo mkdir /usr/local/include
sudo mkdir /usr/local/Frameworks
sudo chown -R $(whoami) $(brew --prefix)/*
brew install git

And running brew doctor after this I get a green light Your system is ready to brew.

This doesn't look right...?

I also created this directory, was need for Python 3 homebrew install:
sudo mkdir /usr/local/Frameworks
and running :
sudo chown -R $(whoami) $(brew --prefix)/*

[jonathan-dejong]

@matinfo adding it to my post for completeness

[embryologist]

solved by changing subdir permissions as mentioned by @ktheory

[ghost]

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

that works.

I've done

sudo chown -R $(whoami) $(brew --prefix)/*

but

brew update

still fails:

brew update
Error: /usr/local is not writable. You should change the ownership
and permissions of /usr/local back to your user account:
  sudo chown -R $(whoami) /usr/local

Is there some way to allow brew update to work?

[matinfo]

@DavidBiesack: What is your current directory permission of /usr/local ?

[DavidBiesack]

ls -ald /usr/local
drwxr-xr-x  22 root  wheel  704 Aug  1 22:14 /usr/local

I believe this is related to Homebrew/brew#3228
However, I've done sudo chown -R $(whoami) $(brew --prefix)/* as noted on that issue.
It's really a homebrew issue, not kickstarter/laptop (but they also closed that issue for comments?)

If you want chown /usr/local

Just disable csrutil disable (Recovery mode)
