Apple iMac (21.5-inch, Late 2015) review

 

No Retina, no cry

Solid build quality ; Slick design ; Rechardable accessories ; Decent speakers

Jagged, 1080p display fonts ; Fusion Drive not standard ; Awkward port location ; No height adjustment

Despite lacking a high-resolution display, Apple's remains an attractive and highly usable computer. Just remember to upgrade to a Fusion Drive to improve boot and loading times.

Apple iMac 21.5-inch (A1418) 2015 review

  (Rating Hidden)

If ever an all-in-one (AIO) computer needed no introduction, this is the one. The 2015 Apple iMac is still a great machine in its own right, but as it's now been replaced with the 2017 Apple iMac 21.5-inch, is now the time to buy? Read the full review...

Review: Apple iMac 21.5in (2015)

 

Apple updates its smaller-sized iMac with an optional 4K screen, but beware the entry-level model.

Adding a Fusion Drive ups the price to $2,459, but it’s a very capable all-in-one PC package.

This newer iMac is perfect!

 

When my first generation iMac gave out, I decided to continue with a newer version. It is slimmer, lighter, and with more memory I am able to keep better organized. The resolution is amazing and transferring older files was so simple!

Fast, simple, compact

 

I bought this as a replacement for for my 10 year old Mac. I am amazed at the improvement. It is enormously faster than its predecessor. I takes up half the space on my desk that the old one did. The screen is much larger and clearer. I spent twice as...

IMAC

 

Works as promised, wish it still had the built in DVD but the USB one works fine. The only complaint is the cost but what can you expect with Apple.

first Apple

 

Very simple to set up. I had one glitch a month after with a firmware/software update, but called Apple and they walked me through it. For what I use this desktop for it works very well for me. I'm glad I made the switch to a Mac.
