MacPro

The MacPro is a MacOS server that hosts A/V editing software e.g., DaVinci Resolve (Studio) and DaVinci Resolve Project Server.

Born in 2012 and still a formidable machine in the year of our Lord 2024! It has been upgraded with a dual hex-core (12-core) Xeon Processors, 512GB NVMe storage, and 96GB RAM.

It's the only machine we know of that can edit 6K video and still burn CD-ROMs!

For security, there is no port forwarding to the device; it can only be accessed via SSH or VNC over VPN.

DaVinci Resolve (Studio)

The MacPro is capable of 6K Video editing locally or remote via VNC over VPN:

vnc://username@resolve.wreckroom.nyc

DaVinci Resolve Project Server

The MacPro also hosts the DaVinci Resolve Server via PostgreSQL.

Configuration File

Here is the location of the config:

sudo vim /Library/PostgreSQL/13/data/pg_hba.conf

For the initial configuration, update the config as such:

# pg_hba.conf file has been edited by DaVinci Project Server. Hence, it is recommended to not edit this file manually.
# TYPE    DATABASE    USER    ADDRESS    METHOD
local    all    all    scram-sha-256
host    all    all    127.0.0.1/32    scram-sha-256
host    all    all    ::1/128    scram-sha-256
host all all 192.168.1.0/24 scram-sha-256
host all all 192.168.3.0/24 scram-sha-256

Note: You must add entries for hosting the WAN (e.g. 192.168.1.0/24) and the VPN (192.168.3.0/24). The VPN address will always need to be added, otherwise you will not be able to connect from VPN.

Restart Postgres

Restart the postgres services via terminal to apply changes to config:

Big Sur

sudo -u postgres /Library/PostgreSQL/13/bin/pg_ctl restart -D /Library/PostgreSQL/13/data

Daily Logs

I was able to find the cause of the VPN not connecting by reviewing the logs:

sudo ls /Library/PostgreSQL/13/data/log

Here was the output from the failed config:

Software Updates

We use OpenCore to keep MacOS up-to-date and extend the life of this now vintage machine.

Limitations

• As a result, WiFi and Bluetooth no longer work as of OS X Catalina.
