I wish I ordered this earlier - my iMac 27" (2019) now works like new, even with macOS Sequoia!
I have an iMac 27" from 2019 that had 16 GB and was recently upgraded with new SSD and macOS Sequoia due to lagging and disk error. However, the new SSD with Sequoia was still making work slow. Then I heard from a colleague who had the same problem that he upgraded his iMac up to 128 GB RAM and it solved the problem. I didn't believe it at first, but order as a test 2x32 GB. Results? Feels like new machine! The next batch is on its way. About the delivery: It arrived to Croatia within 7 days from the order, pretty fast and packed well. Mounting: Very easy. Used the screwdriver to open the lid back on the monitor and replaced the old RAMs with the new ones. Highly recommending to anyone in similar situation! I only wish I did this earlier, years earlier. As a graphic and digital designer I simply love working on 27" screen and didn't want to retire this computer for newer ones if there was a chance to maximise the efficiency even after 6 years since I had bought it. It was truly pain in the a** trying to work with newer version of Adobe Creative Cloud, but now it's solved!

Plug and play
My 2019 Retina 5K 27" iMac came with 16gb factory installed - two 8gb cards. I bought these two 32gb cards to upgrade memory. Nothing could be easier - open the memory compartment in the back and install the two new cards. The factory cards were in slots 1 & 3 (or 0 & 2 if you want to use the odd Apple numbering). I left them in place despite Apple spec that 64gb was max for this iMac. Put the two new 32gb cards in the open slots 2 & 4 (1 and 3 for Apple purists) - closed up and restarted the iMac. It took 30 seconds or so to orient to and recognize the new memory, then booted up fine... no problems or issues and I now have 80gb of fully recognized and usable RAM in my computer. The OWC cards are cost effective, easy to install (press them down into the open slots) and work like a charm.
