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 still use a 2014 MacBook Air 11” for travel because of its size and weight and I was running low on space with 128GB SSD. This new SSD installed easily and transferred all my files without any problems.

I ordered this memory for my iMac and unfortunately I received 2 defective items that made my computer continuously crash. I contacted the seller, and the return window had already closed. However, they did offer to send a replacement instead, and the new ones worked out great. Thank you again.

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.

The product worked, but did not live up to the 3-year warranty claim. I went to the manufacturer's website twice to request a warranty. I have not heard a word back its been two weeks! The Amazon listing clearly says, "Please contact the seller directly for warranty information for this product. You may also be able to find warranty information on the manufacturer’s website." Packaging clearly states 3 year warranty, website says the same thing. Another reason not to trust Amazon is that they only cover 30 days. Then manufacturers hide and are not held accountable.

Snaps in perfectly for my 2019 iMac. I was able to use boot camp to play warzone with 100-120 FPS using the Radeon 570 pro and these ram sticks paired with the apple ram that the computer came with. 24gigs of ram made a night and day difference in term s of performance. I intend to buy another set of ram as soon as I can!

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⚠️⚡️⚡️
