The M3 24-inch iMac has received a significant upgrade with the introduction of Apple’s next-generation System-on-Chip (SoC). In a recent teardown by iFixit, the renowned disassembly experts, the internal workings of this sleek all-in-one device were uncovered, showcasing both improvements and challenges.
Apple revamps internal battery of M3 iMac by ditching dual design
1. External design and compatibility
Externally, the M3 iMac retains the razor-thin profile of its predecessor, the M1 version. Its unique design necessitates an external power supply and also houses an Ethernet port. While the thin chassis contributes to the sleek style, it poses some challenges, as users need to contend with an external power supply.
Fortunately, the M3 iMac is compatible with a VESA mount, but the teardown reveals that internal screws must be removed for this feature to be accessible.
2. Internal changes and cooling solution
The teardown demonstrates that Apple has seamlessly integrated the M3 logic board into the thin frame, accompanied by a cooling solution that surpasses the fanless design found in the 13-inch and 15-inch MacBook Air. Despite the slim design, the 24-inch display can be removed with relative ease by disconnecting a few cables, offering a glimpse into the intricacies of the internal components.
3. Challenges and repairability
One notable challenge highlighted by the teardown is the difficulty of using the M3 iMac with a VESA mount. Users must be prepared to disassemble the stand from the rest of the assembly using internal screws, a task that may be daunting for those unfamiliar with the intricacies of the device.
The teardown also reveals multiple cables, screws, and adhesives, making certain components more challenging to access. However, iFixit suggests that, with the right tools and experience, the M3 iMac appears relatively easy to disassemble. Notably, Apple has introduced a single replaceable CMOS battery, a departure from previous models with two cells.
4. Adhesives and repair recommendations
Addressing concerns about adhesives, the iFixit video host recommends using iMac adhesives for reassembly, citing their ease of removal, cutting, and reinstallation. Despite not providing a repairability score, iFixit acknowledges that, with the right tools and expertise, the M3 iMac seems approachable for repairs.
