Timetec 32GB KIT(4x8GB) Compatible for Apple DDR4 2666MHz for Mid 2020 iMac (20,1/20,2) / Mid 2019 iMac (19,1) 27-inch w/Retina 5K Display PC4-21333 / PC4-21300 CL19 SODIMM Memory MAC RAM Upgrade

This is a great drive. My problem was that I was stuck in a death loop of having a broken OEM drive and a version of MacOS that doesn't support this new drive. So I couldn't upgrade the OS, and I couldn't make this work, even after days of effort. "You need this to get that. But you need THAT to get THIS!" Stupid Apple. I can't understand why after all this time, they still make simple things difficult.But if you have the OS version they specify, this drive will work great. And you can't beat the price.

I got this hard drive to install in a older computer and it fit perfectly and it definitely made huge improvement over the one that was installed.

Good product and excellent seller and trustworthy for fast shipping

It took a of searching on the Internet to finally make it work. I wanted to do a clean install on a fresh new SSD. I am very happy that Apple made this possible without even a USB boot drive. Everywhere I search all told me to use Command+R to load the original OS (Sierra for my Macbook), or Command+Alt+R to load the latest OS (Monterey at this writing). The first time when I did this, my Macbook could not detect the SSD with either method. I quickly returned and got a replacement (Thank you Amazon). On the second SSD, My Macbook was still unable to detect it with the Command+R method. When I tried the Command+Option+R method, it detected it! Except it still would not install until I used the Disk Utility to create a partition. All is good now? Not quite. The install utility complained there was no Internet connection. And it did not give me the option to connect to my WIFI. The Macbook does not have an Ethernet port. What now? Lucky for me, I just happened to have RJ45 to USB A Ethernet adapter. About 1.5 hours later, the Monterey OS was fully installed.Overall, I am quite happy with this.

Even though my computer said this Ram was operating okay, it keep causing my iMac to shut down.It took me like 4 months and many calls with Apple to isolate the problem. And after submitting my crash reports and computer log to Apple, did an Apple engineer diagnose my problem - it's this Timetec Ram. I was instructed to remove it.

The media could not be loaded. Recently bought an “as is” non-functional 2013 21.5” iMac that apparently had a S.M.A.R.T. failing stock NVMe SSD. This drive was a flawless replacement and works perfectly.*warning*⚡️⚡️⚠️Replacing the drives on these intel iMacs is an advanced level endeavor that requires a complete tear down of the system, and can present the danger of possible electric shock if you are not knowledgeable or fail to take preventative precautions⚠️⚡️⚡️

Probably a good product but I never had a chance to use it because my laptop didn’t use this style of memory. I had to return it.

No, I do not expect this to make my internet go faster. Nor my browser. Nor programs/apps that don't need a lot of memory. I bought the upgrade for a few reasons: Value, as the memory is way less than Apple and works just fine. And for my larger bloated programs, like Bridge or Lightroom, this will help. Think of this memory upgrade as increasing the space on your desk. You can multitask a lot easier if you have space to work. Same with computers. If they can access space quickly to do tasks that get overridden with the next task, that's what this is basically for. If you work with commercial programs or large files, think photos, this will help. Hope that helps. Just do it. ;)
