## How to increase maxfiles on macOS

To increase maxfiles on macOS, create the following file:

(Note: you'll need to use sudo)

/Library/LaunchDaemons/limit.maxfiles.plist:
```
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>524288</string>
      <string>524288</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>
```

Execute the following command:
```
sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
```

Reboot.

To check if it's working, you can use `ulimit -n` command.
