Golden build, i7-8700K iGPU HD630 and dedicated PCIe Wifi+BT.

I put together this build for a friend that has huge iTunes and iPhoto libraries and could not get a Mac with a large enough SSD (Only Mac"Pro" (lol) and iMac"pro" (lol) allow for larger than 1 or 2Tb SSD). Fusion drive was not good enough. 
He's very happy with this built, using all of his Apple peripherals as usual (apple watch, ipad, iphone, keyboard, mouse...). 
Plus, his computer is faster than a 3500€ iMac. (8e gen Intel core i7 vs 7 gen Inte core i7) + decent cooling solution. + he can add one more NVMe M.2 drive and three more SATA SSDs. 

Components : Gigabyte Z370N rev 1.0, i7-8700K, Samsung 970 EVO 1Tb (PCIe), Samsung 860 EVO 2Tb (SATA), PCIe Wifi+BT (BCM946302CS)


0) Prepare the USB drive using the normal procedure

Compare a particular column of 2 different csv files & get the data from second file what is not there in first file

It will fail if it is possible that any data from the first column could end up in any other column or there are any spaces in the data.

Using bash and GNU grep.

grep -v -Ff <(cut -d',' -f 1 file1.csv) file2.csv > file3.csv

After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

Database files have to be updated before starting the server, here are the steps that had to be followed:

# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql
