<title>macOS Installation</title>
<para>
Starting with macOS 10.15 (Catalina), the root filesystem is read-only.
This means <filename>/nix</filename> can no longer live on your system
volume, and that you'll need a workaround to install Nix.
</para>
<para>
The recommended approach, which creates an unencrypted APFS volume
for your Nix store and a "synthetic" empty directory to mount it
over at <filename>/nix</filename>, is least likely to impair Nix
or your system.
</para>
<note><para>
With all separate-volume approaches, it's possible something on
your system (particularly daemons/services and restored apps) may
need access to your Nix store before the volume is mounted. Adding
additional encryption makes this more likely.

<title>Eventual solutions?</title>
<para>
All of the known workarounds have drawbacks, but we hope
better solutions will be available in the future. Some that
we have our eye on are:
</para>
<orderedlist>
<listitem>
<para>
A true firmlink would enable the Nix store to live on the
primary data volume without the build problems caused by
the symlink approach. End users cannot currently
create true firmlinks.
</para>
</listitem>
<listitem>
<para>
If the Nix store volume shared FileVault encryption
with the primary data volume (probably by using the same
volume group and role), FileVault encryption could be
easily supported by the installer without requiring
manual setup by each user.
</para>
</listitem>
</orderedlist>
</note>
<section xml:id="sect-macos-installation-change-store-prefix">
<title>Change the Nix store path prefix</title>
<para>
Changing the default prefix for the Nix store is a simple
approach which enables you to leave it on your root volume,
where it can take full advantage of FileVault encryption if
enabled. Unfortunately, this approach also opts your device out
of some benefits that are enabled by using the same prefix
across systems:
<itemizedlist>
<listitem>
<para>
Your system won't be able to take advantage of the binary
cache (unless someone is able to stand up and support
duplicate caching infrastructure), which means you'll
spend more time waiting for builds.

</listitem>
<!-- TODO: may be more here -->
</itemizedlist>
<!-- TODO: Yes, but how?! -->
It would also possible (and often requested) to just apply this
change ecosystem-wide, but it's an intrusive process that has
side effects we want to avoid for now.

</para>
<para>
</para>
</section>
<section xml:id="sect-macos-installation-encrypted-volume">
<title>Use a separate encrypted volume</title>
<para>
If you like, you can also add encryption to the recommended
approach taken by the installer. You can do this by pre-creating
an encrypted volume before you run the installer--or you can
run the installer and encrypt the volume it creates later.
<!-- TODO: see later note about whether this needs both add-encryption and from-scratch directions -->
</para>
<para>
In either case, adding encryption to a second volume isn't quite
as simple as enabling FileVault for your boot volume. Before you
dive in, there are a few things to weigh:
</para>
<orderedlist>
<listitem>
<para>
The additional volume won't be encrypted with your existing
FileVault key, so you'll need another mechanism to decrypt
the volume.
</para>
</listitem>
<listitem>
<para>
You can store the password in Keychain to automatically
decrypt the volume on boot--but it'll have to wait on Keychain
and may not mount before your GUI apps restore. If any of
your launchd agents or apps depend on Nix-installed software
(for example, if you use a Nix-installed login shell), the
restore may fail or break.
</para>
<para>
On a case-by-case basis, you may be able to work around this
problem by using <command>wait4path</command> to block
execution until your executable is available.
</para>
<para>
It's also possible to decrypt and mount the volume earlier
with a login hook--but this mechanism appears to be
deprecated and its future is unclear.
</para>
</listitem>
<listitem>
<para>
You can hard-code the password in the clear, so that your
store volume can be decrypted before Keychain is available.
</para>
</listitem>
</orderedlist>
<para>
If you are comfortable navigating these tradeoffs, you can encrypt the volume with
something along the lines of:
<!-- TODO:
I don't know if this also needs from-scratch instructions?
can we just recommend use-the-installer-and-then-encrypt?
-->
</para>
<!--
TODO: it looks like this option can be encryptVolume|encrypt|enableFileVault
It may be more clear to use encryptVolume, here? FileVault seems
heavily associated with the boot-volume behavior; I worry
a little that it can mislead here, especially as it gets
copied around minus doc context...?

<!-- TODO: and then go into detail on the mount/decrypt approaches? -->
</section>
<section xml:id="sect-macos-installation-symlink">
<!--
Maybe a good razor is: if we'd hate having to support someone who
installed Nix this way, it shouldn't even be detailed?
-->
<title>Symlink the Nix store to a custom location</title>
<para>
Another simple approach is using <filename>/etc/synthetic.conf</filename>
to symlink the Nix store to the data volume. This option also
enables your store to share any configured FileVault encryption.
Unfortunately, builds that resolve the symlink may leak the
canonical path or even fail.

Because of these downsides, we can't recommend this approach.

# - the "xART session seeds recovery utility"

# xartutil: ERROR: No supported link to the SEP present
# - xART sessions/seeds are present when a T2 chip is
# (and not, otherwise)
# - the presence of a T2 chip means a newly-created
# volume on the primary drive will be
