Used & refurbished 27-inch iMac

27-inch Intel iMac: compare configuration, not just screen size

The Retina 5K models offered here from 2017, 2019 and 2020 differ in CPU, graphics, RAM and storage. A larger screen alone does not make a device better for your apps. Compare actual specifications and software requirements together.

When can an Intel iMac suit my workspace?

An Intel model can be interesting when your specifically checked apps, extensions or device drivers fit it. Check the supported macOS version for the exact model year and your software’s current requirements. For a newly planned setup, also compare Apple silicon. Good cosmetic condition does not imply a fixed number of future update years.

Is a 1 TB Fusion Drive the same as a 1 TB SSD?

No. Fusion Drive combines a mechanical hard drive and flash storage into one volume. Its entire capacity is therefore not pure SSD storage. If app launches and work with many files matter, explicitly compare SSD offers. Then choose capacity around apps, projects and free working space, rather than the largest TB figure alone.

Can I upgrade RAM later?

The 27-inch Retina 5K models from 2017, 2019 and 2020 have accessible SO-DIMM slots. Compatible modules, supported configurations and slot population depend on the exact model. Check Apple’s guidance before upgrading and include its cost. Intel system RAM is also not the same as the graphics card’s memory.

Can I use the 5K iMac as a MacBook monitor?

These Retina 5K models do not support Target Display Mode. Video output to an external monitor does not turn the iMac into an ordinary monitor input for another computer. If you mainly want a screen for your MacBook, compare a standalone display rather than another complete computer.

27-inch iMac or a Mac with a separate monitor?

Compare the complete workspace: an iMac includes its display. With a desktop Mac and external monitor, you can choose the computer and display separately. Check software compatibility, storage type and included accessories before buying.
