Is this ram compatible with imac (21.5-inch, late 2015) that already has 8 gb 1867 mhz ddr3 ram?

Hello! This memory would only be for the 27" Late 2015 iMac. The 21.5" Late 2015 does not have upgradeable memory.

Hello which should I buy for a 2009 20 inch IMac??

Hello. The following memory in the link below would be the compatible memory for a 2009 20" iMac. https://www.amazon.com/OWC-204-pin-Upgrade-MacBook-OWC8566DDR3S8GP/dp/B00BKVQFU2/ref=sr_1_3?crid=PO0WVFXYZTU5&keywords=OWC8566DDR3S8GP&qid=1648742589&sprefix=owc8566ddr3s8gp%2Caps%2C69&sr=8-3&th=1

Can my imac late 2015 27" 5k model use 2x16gb memory sticks? or do i need to get 4x8gb sticks?

I believe you can only use 4 sticks of 8GB for that model. You always have to use pairs of memory. I bought the 32 GB package to max out my iMac, but one of the slots on my computer would not accept an 8GB stick, so I had to put an original 4GB stick back in that slot and its paired mate. I still have two sticks of 8GB that work, but I can't use. I am willing to sell them.

Is this compatible with MacMini Late 2012”?

Hello. No this OWC memory 1866MHz is not compatible with a MacMini late 2012.
