1. macOS 10.14.3 Mojave or later must be installed before installing any kits utilizing 64GB memory modules.
2. Apple iMac Pro can use either RDIMM or LRDIMM, but they cannot be combined. The system will not function with a mixed configuration. For maximum performance, population of all 4 DIMM slots is recommended.
3. Professional Installation Required! The iMac Pro DOES NOT feature a memory door on the back allowing for easy upgrades. Upgrading the iMac Pro's memory requires dismantling the computer to gain access to the memory slots. This is a highly complex process that requires a skilled technician.
