The M1-M4 iMac appears to be the perfect desktop computer on paper. It boasts a fast processor, a bright Retina display, an all-in-one design that minimizes cable clutter, Thunderbolt support for external drives, and a 24-inch screen that strikes a balance between size and usability. However, after months of use, I have encountered several issues that often go unmentioned in reviews.
I originally sold my M1 iMac after purchasing a second-hand 2017 iMac with SSD storage. Thanks to OCLP, I have had no issues running Sequoia 15.5 on it. While I acknowledge that this machine will no longer receive security updates after Autumn 2028, I’m confident I can adapt (Linux, anyone?)
when that time comes. For my work—reading technical literature, writing, coding, and analyzing data—along with some light photo processing in Pixelmator, I had high expectations from the new iMac. Unfortunately, my experience has revealed some drawbacks.
First, the screen brightness is notably less impressive than that of older iMacs. My SpyderX measured only 490 nits, compared to the 609 nits of the 21.5-inch model. This leads to issues in well-lit environments where I find myself longing for more brightness.
In contrast, the older model performs well across varying lighting conditions. Additionally, the reflective white borders of the screen detract from the focus needed for professional tasks. It seems this design choice aims to make the iMac blend more seamlessly into home environments, rather than cater to professional needs.
Furthermore, the screen does not compensate for the additional workspace provided by a 27-inch iMac. It feels slightly larger than the 21.5-inch model, but my workflow remains largely unchanged. Lastly, the noticeable power adapter, resembling a bulky white brick, detracts from its all-in-one look unless well-hidden.
