On a MacBook *Air*, the RAM is unfortunately soldered to the mainboard - on all generations. The installation of more RAM on MacBooks (with / without Pro) was only possible on the models before the switch to Retina displays, i.e. until mid-2012.
Hello Kjamil
Unfortunately, I don't know. I have a Mac 13-inch Mid 2012. The manufacturer's specification for this model was that it can only run with 2 x 4 GB RAM. Mine works wonderfully with 2 x 8 GB. Kind regards Paul
Upgrading is super easy, there are instructions on ifixit. It takes about 10 minutes. This RAM should work. However, it doesn't really make sense. The CPU is Dual Core, could be an i7-2620M CPU. A Mac Mini 2011 can only run High Sierra as the maximum supported operating system:
High Sierra
macOS 10.13.x
The CPU is somewhat the same performance as a very cheap mini PC device with an Intel Celeron N4100, so it's really not very fast. I would install the current OS and then resell the device and not invest any more money in it. Unfortunately, 16GB RAM doesn't make the old hardware any faster. You could buy an SSD, but I don't know if it's worth it. 80 for RAM and another 50 for an SSD, that would make it a bit faster, one of those would fit, for example, and you could then install the operating system on it:
Adata Ultimate SU650 (512 GB, 2.5")
I can't say certified. However, the memory must be reformatted because it comes with NTFS format. Unfortunately, the iMac can only read this format. After reformatting, the memory works perfectly.
This is possible in a 27" model, but not in a 21.5", or only with a lot of effort. Moreover, it is hardly worth it, since the latest operating system no longer works there either.
If you can't do it yourself, then don't bother and buy a slightly newer, possibly used one.
But if you unscrew it, then put a fast SSD disk in it right away!
Hello! Theoretically, if your Mac model's RAM memory is integrated (soldered) to the motherboard, you CANNOT replace it. Otherwise, there should be no problem.
No, the P8B75-M LX Mainboard requires DIMM 240-Pin DDR3 (unbuffered) memory, whereas this is SODIMM 204-Pin DDR3L(wrong formfactor).
I'd recommend one of the following RAM sets (if you haven't resolved this issue already):
Corsair Vengeance LP (2x, 8GB, DDR3-1600, DIMM 240)
Corsair Vengeance Pro (2x, 8GB, DDR3-1600, DIMM 240)
The memory works perfectly in my iMac (Late 2012) and the delivery was as always fast and reliable!
CORSAIR's Mac memory kits are tested at Apple Developer Compatibility Labs and work with most MacBook® Pro, iMac®, and Mac mini systems shipped in 2011.
I still have two of these bars (2 x 8 GB) that I don't need and can give them away.
here you can find the specifications.

Important: it is best to retrofit the same ones that are already installed!
I don't think according to the internet. You need the DDR3-1866, DIMM 240 for desktop. Check again and copy/paste with: iMac (Retina 5k 27-inch late 2015) in browser. Greetings
Hello,
No, these memories are not compatible with your device. Here is a link that might help you:

Have a nice evening,

If you can open the case without damage, then yes.
The memory in the 21.5 iMac cannot be changed without tinkering. The 8 GB that are inside should be enough for the part anyway, if a Fusion drive is inside.
Otherwise, replace the HD with an SSD and it will be in full working order again.
