Check this is the correct service

Listing: Apple iMac 27-inch Retina 5K 2017 (A1419/iMac18,3) RAM Upgrade

• Year: 2017
• A-number: A1419
• Model Identifier: IMac18,3

A-number alone can span more than one configuration. We verify the full model identity and fitted component before ordering or fitting.

Common symptoms

• The device slows down under multitasking or memory-intensive work
• Applications report insufficient memory
• A compatible removable memory module has failed

Similar symptoms can have more than one cause. We test first and obtain approval before any different or additional paid repair.

What is included

• Exact model and upgradeability check
• Compatible memory selection within the listed scope
• Parts, labour, installation and memory testing
• Before-and-after configuration confirmation

Installed repair only: Minko’s Macs does not sell this repair part separately. We confirm compatibility and fit it as part of the service.

How the service works

1. Identify the exact model and maximum supported memory
2. Confirm that the memory is removable and the requested configuration is supported
3. Power down and isolate the device
4. Fit the compatible modules using anti-static handling
5. Run memory and stability checks after reassembly

Turnaround: Normal turnaround is 5–7 working days after check-in. Parts availability, additional faults or customer approval can extend this; we will contact you before carrying out extra paid work.

One-year warranty

The fitted replacement part or completed component repair, together with its related workmanship, carries a one-year warranty. Accidental or impact damage, consumable wear and unrelated faults are excluded. If inspection finds liquid damage, repair work to an existing liquid-affected component has no warranty because corrosion can continue; any new replacement part we fit still carries its one-year warranty. Statutory rights remain unaffected.

Frequently asked questions

Can every Mac be upgraded?
No. Many modern Macs and some iMac models have soldered or unified memory that cannot be upgraded after purchase.

Will more memory fix every slow computer?
No. Storage, software, temperature and hardware faults can also cause poor performance, so the device is assessed first.

Can I buy the RAM separately?
No. This listing is for a fitted service.
