The latest Apple iMac assumes the ultra-thin design of its predecessor, but makes replacing the CMOS battery a little easier. RAM or SSD upgrades are still not possible, but at least the connections and the stand can be replaced.

A new M3-based model of the Apple iMac was introduced the end of October, which reportedly delivers 35% faster CPU performance and 65% higher GPU performance. The new chip was also accompanied by upgrades to Wi-Fi 6E, Bluetooth 5.3 and up to 24GB of memory.

The 24-inch, 500 nits bright 4.5K display and the 11.5 millimeter thin housing were adopted directly from the previous model. iFixit has now disassembled Apple's latest all-in-one to see if there were any other innovations hidden inside. The design has hardly changed; the display is glued directly into the case as usual, so users have to cut through the adhesive to get inside and may have to replace the adhesive to reattach the screen.


Most of the space behind the display is taken up by the speakers, with the stand attached to the middle of the case. An annoying aspect is that in order to replace the stand with a VESA mount, the screen first has to be removed from the housing, which makes this process much more complicated than necessary. The mainboard, which is downright tiny by desktop standards, is located in the 'chin' under the display.

As usual with Apple, neither the SSD nor the RAM can be replaced and are firmly soldered to the Apple M3 mainboard. On the other hand, replacing the two fans, the Thunderbolt ports or the CMOS battery is relatively easy, although the new model only has one battery instead of the previous model's two.
