Planning a MacBook upgrade? Before you buy RAM or an SSD, you need to know whether your MacBook’s components are actually replaceable. Apple has progressively soldered more components over the years, and since 2016, virtually every MacBook has non-upgradeable RAM and storage. Here is a complete list of every MacBook model and what’s soldered versus replaceable.

| MacBook Pro 14″/16″ M4/Pro/Max | 2024-2025 | Soldered | Soldered | Latest generation. All memory and storage soldered. |
What is “Unified Memory” and Why Can’t It Be Upgraded?
Apple Silicon MacBooks (M1 and later) use a technology called unified memory. Unlike traditional computers where RAM sits in separate sticks plugged into slots, unified memory is physically part of the processor package itself.
The RAM chips are mounted directly on the same substrate as the CPU, GPU, and Neural Engine. This gives Apple Silicon incredible memory bandwidth (up to 800GB/s on the M4 Max) and power efficiency, but it means the memory literally cannot be separated from the processor.
This is fundamentally different from older Intel MacBooks where RAM was soldered to the logic board as a cost/design choice — with Apple Silicon, it’s an architectural necessity.
Alternatives When You Can’t Upgrade
External Thunderbolt/USB-C SSD: The fastest and most practical way to expand storage. A Thunderbolt 4 SSD delivers 2,800MB/s read speeds — fast enough for video editing directly from the external drive.
SD card semi-permanent storage: MacBook Pro 14″/16″ models have an SDXC card slot. A flush-fit 1TB SD card like the Samsung PRO Plus adds permanent storage that doesn’t stick out.
iCloud and cloud storage: Offload photos, documents, and old files to iCloud. The “Optimise Mac Storage” feature automatically manages local space.
Sell and rebuy: If you genuinely need more RAM, the only option is to sell your current MacBook and buy a new one with more memory. Apple’s resale values are strong, so the net cost may be less than you think.
Our Top Recommendations

Is the SSD soldered on MacBook Air M3?
Yes. The MacBook Air M3 has its SSD storage soldered directly to the logic board. It cannot be upgraded, replaced, or expanded internally. Use an external USB-C SSD for additional storage.
Can I upgrade MacBook Pro M4 RAM from 16GB to 32GB?
No. The MacBook Pro M4 uses unified memory that is part of the processor package. RAM cannot be upgraded after purchase. You must select 16GB, 24GB, 32GB, or higher at the time of buying.
Which is the last MacBook with upgradeable RAM?
The mid-2012 MacBook Pro 13″ and 15″ Non-Retina models (A1278 and A1286) are the last MacBooks with standard SODIMM RAM slots. They can be upgraded to 16GB using standard DDR3L modules.
Can a repair shop upgrade soldered MacBook RAM?
In theory, microsoldering specialists can sometimes replace soldered NAND chips, but this is extremely risky, voids any warranty, and is not recommended. For Apple Silicon Macs with unified memory, it is physically impossible as the RAM is inside the chip package.
Should I buy 8GB or 16GB MacBook Air?
We strongly recommend 16GB for any MacBook purchased in 2024 or later. 8GB will feel constraining within 1-2 years, especially as macOS and apps become more memory-hungry. Since you cannot upgrade later, spending the extra £200 upfront is worthwhile.

Final Thoughts
The era of upgradeable MacBooks is over. Every MacBook made since 2016 has soldered RAM and SSD that cannot be changed after purchase. The key lesson: buy more RAM and storage than you think you need today, because you’re stuck with it for the life of the machine. Use external storage for expansion and our compatibility checker to find the right accessories.
