Life can be so beautiful, if you have a wide vision.
Download STL files here. To keep the strength and use less plastic I changed the fill to honeycomb and added two bars near the edges to prevent bending. Made this as part of my LACK modification for “Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table – Prusa Research” https://www.thingiverse.com/thing:2864118

Syntax Interface to the [raw] stored preference data: scutil --prefs [preference-file] Check the network reachability of a host, IP address, or a pair of local and remote IP addresses: scutil -r [-W] { nodename | address | local-address remote-address } Check for (and optionally wait for the creation of or posting of a notification to) a dynamic store key: scutil -w dynamic-store-key [-t timeout] Report and update a select group of persistent system preferences, e.g. Hostname: scutil --get pref scutil --set pref [newval] Report the current DNS configuration: scutil --dns Report the current system proxy configuration: scutil --proxy Commands for monitoring and interacting with VPN connections: scutil --nc nc-arguments Interactive command line interface to the "dynamic store" data: type help for commands (maintained by configd) scutil Key -r [-W] { nodename | address | local-address remote-address } Check the network reachability of the specified host name, IP address, or a pair of local and remote IP addresses. One or more of the following strings will be reported to standard output. Not Reachable The specified nodename/address cannot be reached using the current network configuration. Reachable The specified nodename/address can be reached using the current network configuration. Transient Connection The specified nodename/address can be reached via a transient (e.g. PPP) connection. Connection Required The specified nodename/address can be reached using the current network configuration but a connection must first be established. As an example, this status would be returned for a dialup connection that was not currently active but could handle network traffic for the target system. Connection Automatic The specified nodename/address can be reached using the current network configuration but a connection must first be established. Any traffic directed to the specified name/address will initiate the connection. Local Address The specified nodename/address is one associated with a network interface on the system. Directly Reachable Addresss Network traffic to the specified node- name/address will not go through a gateway but is routed directly to one of the interfaces on the system. The reachability can also be monitored by specifying the -W (watch) option. This will result in the current status being reported as well as the status when/if the network configuration changes. A zero exit status will be returned when the reachability status is reported correctly. A non-zero exit status will be returned if errors are detected with an error reported to standard error. -w dynamic-store-key [-t timeout] Check if the specified key exists in the "dynamic store" data main- tained by configd(8). If present, scutil will return with a zero exit status. If not present, scutil will wait for the specified time for data to be associated with or a notification to be posted using the key. A non-zero exit status will be returned if the key was not created/posted within the specified time. scutil will wait indefinitely if a timeout of 0 seconds is specified. The default timeout is 15 seconds. --get pref Retrieves the specified preference. The current value will be reported on standard output. Supported preferences include: ComputerName The user-friendly name for the system. LocalHostName The local (Bonjour) host name. HostName The name associated with hostname(1) and gethostname(3). --set pref [newval] Updates the specified preference with the new value. If the new value is not specified on the command line then it will be read from standard input. Supported preferences include: ComputerName LocalHostName HostName The --set option requires super-user access. --dns Reports the current DNS configuration. --proxy Reports the current proxy configuration. --nc nc-arguments Provides a set of commands for monitoring and interacting with VPN connections. Use --nc help for a full list of commands. |

In Mac OS X El Capitan, Apple added SIP (System Integrity Protection), previously referred to as rootless mode in the beta releases. SIP is essentially just a block on editing the /System, /sbin, and /usr directories (with the exception of the /usr/local subdirectory). It is recommend keeping SIP enabled whenever possible, so enable it again after you have finished making changes, unless an application […]
