Q: Can this ram be mixed with apple's pre-installed ram? i've read that crucial memory has not played well with apple ram in the past.

Hey David!Thank you for reaching out to us, this is a great question. We obviously can't speak for Crucial or their product, however with only a single exception which comes to mind (16GB modules for the 2010-2012 Mac Pro) we have never had issues mixing Apple RAM with OWC RAM in the last 5-10 years. You would be just fine mixing this RAM with others, though we always advocate that the larger modules go in the "first" slots (ordered from top to bottom) as the machine may not "see" the larger modules if done the other way around. Let us know if you have another question, and if you want to get in to a longer form discussion I'd recommend getting in touch with our excellent support team at: https://www.owcdigital.com/support/contactHave a wonderful rest of your day!

Q: If I add 2x16gb sticks to the 2x4gb sticks. Does it matter which slots I had them to? Let's say 1 is the bottom slot and 4 is the top?

The answer OWC gave was true in my case. My iMac came with Apple's two 4GB sticks located in slots 2 and 4. Initially I followed advice from another source to switch the location of those sticks to slots 1 and 3, and put the two 8GB OWC sticks in slots 2 and 4, purportedly because Apple had installed their sticks in the locations that are used first by the CPU, so it would be speedier to have the larger 8 GB there. I did that, and the machine did nothing for over a minute. After reading the answer by OWC here, I put the 8GB sticks in slots 1 and 2, and the 4GB sticks in slots 3 and 4, and the machine booted in a few seconds.

Q: Will this owc memory work on my 2018 macbook pro laptop?

Hello. The 2018 MacBook Pro does not have removable memory. You would not be able to replace the memory at all.

Q: Is it compatible with iMac 2019 21.5" Core-i3?

Hello. No this is not compatible memory for a iMac 2019 21.5".
