This site will be down from about 11:00 AM to 1:00 PM Pacific Time for a server upgrade.
Actual downtime may be much shorter, but that is my schedule if unexpected glitches occur.
There are/were two reasons for the update:
- To double the size of the server SSD to 1TB
- To double the CPU cores from 2 to 4.
The prior machine (2012 MacBook Pro 16GB / 512GB dual-core Intel i7) had been running 24 X 7 for almost 4 years in the server room with zero problems (nearly 5.5 years total), but it was low on disk space, so I swapped it out for a better machine (2012 MacBook Pro 16GB / 1TB / 4-core Intel i7). Apple MacBook Pro machines from 2012 make highly reliable servers. I ran one earlier model for nearly a decade 24 X 7 with zero problems.
OWC sells used Macs including the 2012 MacBook Pro and the superb quality of the 2012 MacBook Pro model is presumably why they still sell for good money 5+ years later. I recommend sticking with macOS El Capitan on these machines, but they can run “we were smokin' it when we coded it” macOS High Sierra.
OWC also has used MacMini in many different configurations. We still use one that is from 2009 or so.
