Who it's for: Anyone keeping a 2013–2017 Mac alive — replacing a failing original SSD, jumping from 128GB or 256GB to real working capacity, or squeezing years more use out of a machine that's otherwise still perfectly good.

FAQ:

• How do I know if my Mac is compatible? Check the model number (A1465, A1466, A1502, A1398, A1418, A1419, A1347, or A1481) printed on the bottom case of your MacBook or the back of your iMac, or open → About This Mac and match the model and year against the list above.
• Do I need to do anything before installing? Yes — update to macOS 10.13 (High Sierra) or later before swapping the drive. Earlier macOS versions don't include the NVMe driver and won't recognize the ON900A. Back up with Time Machine so you can restore to the new drive.
• Why is my measured speed lower than 3,500 MB/s? On 2013–2014 models, the Mac's own PCIe 2.0 interface is the bottleneck, so real-world speeds will be below the drive's rated maximum — still a substantial upgrade over the original Apple SSD. 2015 and later models with PCIe 3.0 get closer to full speed.
• Will macOS features like TRIM and hibernation work? Yes — the ON900A supports TRIM, NCQ, and S.M.A.R.T. under macOS and works with standard macOS power management.
