I have an iMac 21.5, late 2012 running macOS Mojave. It is really getting slow to process and I am wanting to upgrade the Memory from 8 GB to 16 GB. How can I do this when the Apple stores are closed?
iMac 21.5″, macOS 10.14
RAM is likely not the major issue here.
About 95 percent of slow 21.5-inch iMac reports here are not due to RAM but rather to the slow mechanical hard drives Apple uses in the entry level iMacs. The base drive in a 2012 iMac 21.5 is rated at only half the transfer speeds for the same iMac model made in 2011.
Because of the need for professional RAM installation and the associated extra costs over the cost of RAM ((between US$140 and $175 for labor and the required resealing kit) it behooves you to look for other ways to get more speed. There is a do-at-home option but we need to make certain the drive is the issue first. To that end, please download Etrecheck from the Mac App Store and run it, and post the results using these instructions:

Apple Stores do repair work, but generally will not do upgrades.
The Late 2012 21.5" iMac must be completely dissembled to upgrade the RAM.
You need to call your local Authorized Apple Service Provides and see if they provide upgrade service.
