NOTE: macOS 10.14.3 Mojave or later must be installed before installing any kits utilizing 64GB or 128GB memory modules. iMac Pro can use either RDIMM or LRDIMM, but they cannot be combined. The system will not function with a mixed configuration. OWC Memory Upgrades will use matching memory.

Please note:
OWC requires that the mailing label used to send in your iMac Pro includes an attention line referencing the OWC service reference number. An OWC representative will contact you to provide the service reference number within 24-48 business hours. Once we have received your iMac Pro, please allow 3-5 business days to complete the upgrade process.

There is a $25 cancelation fee for any iMac Pro Upgrade service canceled after payment has been received, but prior to upgrade work being performed. Once the upgrade has been performed, the service cannot be canceled so take one more moment to review your upgrade options.

Any items ordered along with this iMac Pro upgrade will be held on order until the upgraded iMac Pro is available to ship. If there are items you would like to receive prior to the availability of your upgraded iMac Pro, you will need to place a separate order for those items.
