iMac 2019 Memory


You can upgrade your iMac with more memory. The nice thing is that you can keep the orginal memory that came with the computer.

I found a 32GB memory on for $139! (Compaired to $600 that Apple was asking when I was buying the iMac.)

This is the memory that I installed: Crucial 32GB Kit (16GBx2) DDR4 2666 MT/s (PC4-21300) DR x8 SODIMM 260-Pin Memory - CT2K16G4SFD8266


October 4, 2019: Installed with the computer.

October 7, 2019: Updated to the new MacOS.

In MacOS 10.15, Apple added the Startup Disk to the overview panel.

November 7, 2021: Updated to the new MacOS.

Apple Thunderbolt Display - October 19, 2019


I have an external 20-inch Apple Cinema Display that I would like to connect to this iMac. The problem is that it won't plug directly into the computer, I'll have to get a converter.

I have the Model number: A1081 display, which means the display uses a DVI connector. I will need a DVI to Thunderbolt 3 (USB-C) or a DVI to USB 3 adapter.

Amazon Pricing:

  • DVI to USB 3 is $45.95
  • DVI to Thunderbolt 3 (USB-C) is $13.95

Update: October 20, 2019


I purchased the DVI to Thunderbolt 3 (USB-C) from for $13.95 on October 19, 2019.

This works perfectly with my Apple Cinema Display (MA467). It works perfectly - just like my Thunderbolt adapter. The only thing that won't work is the Firewire port, but Apple has pretty much killed that since 2012 - when the last computer shipped with a Firewire port. Certainly USB-C is the way to go now.

Speed Difference:

USB-C (Thunderbolt 3) 10 Gbps
USB 3 5 Gbps
FireWire 800 800 Mbps
USB 2 480 Mbps
Firewire 400 400 Mbps

Cool tool installed on December 25, 2019:

Installed a cool USC-C Clamp Hub so that I can access various ports on the front of the computer - that way I don't have to reach to the back of the computer for temporary items.

Software Install

These are the "must have" applications that I plan on installing on the computer. This computer will have a smaller base hard drive, so I don't want to install applications that I don't think I'll be using.
