EveryMac.com's iMac Pro Q&A answers questions about the now discontinued iMac Pro models which all have a 27-Inch display and a dark gray housing. Collectively, these systems can be identified by the A1862 model number.
Questions range from "What are all the differences between the iMac Pro models?" to "How do you upgrade the RAM in the iMac Pro models? Is it even possible? How much RAM does each model actually support?" and everything in between.
Please note that the iMac Pro has been discontinued. However, this Q&A has been updated subsequently and can be quite useful for anyone buying or selling one of these models on the used market.
Similar looking non-pro "Tapered Edge" iMac models use silver-colored aluminum cases. Regardless of release date or unofficial name, these systems can be identified collectively by model numbers A1418, A1419, A2115 and A2116.
EveryMac.com offers a separate "Tapered Edge" Aluminum iMac Q&A that covers these other iMacs.
