Mac mini SSD upgrade (Apple-documented facts)
Published: Updated:
Scope. This page lists only storage and memory facts published in Apple Support tech specs and Apple’s Mac mini memory article. It does not include teardown DIY steps, third-party module guides, or “how we upgraded one.” If you need more capacity after purchase, Apple’s documented path on these pages is to choose storage when configuring the Mac, use external drives, or use Apple / authorised service — not a Lab how-to.
Short answer
Apple publishes SSD capacity as a configure-to-order option on each Mac mini generation’s tech specs. For Apple silicon Mac mini (M1 2020, 2023, 2024/M4 and later listed on the memory article), Apple states that unified memory is integrated into the M-series package and cannot be upgraded after purchase. Apple does not publish a user “install a larger internal SSD” procedure for those models the way it still documents RAM swaps on much older Intel minis (Upgrade or install memory in your Mac mini).

Storage options Apple lists (configure at purchase)
Capacities below are Apple’s listed SSD options / configure-to-order maxima from each generation’s Support tech specs. Apple’s footnotes: 1GB = 1 billion bytes, 1TB = 1 trillion bytes; actual formatted capacity less.
Mac mini (M1, 2020)
From Mac mini (M1, 2020) tech specs:
| Apple listing | |
|---|---|
| Default SSD | 256GB |
| Configurable to | 512GB, 1TB, or 2TB |
Mac mini (2023) — M2 / M2 Pro
From Mac mini (2023) tech specs:
| Chip | Default SSD | Configurable to |
|---|---|---|
| Apple M2 | 256GB | 512GB, 1TB, or 2TB |
| Apple M2 Pro | 512GB | 1TB, 2TB, 4TB, or 8TB |
Mac mini (2024) — M4 / M4 Pro
From Mac mini (2024) tech specs:
| Chip | Default SSD | Configurable to |
|---|---|---|
| Apple M4 | 256GB | 512GB, 1TB, or 2TB |
| Apple M4 Pro | 512GB | 1TB, 2TB, 4TB, or 8TB |
The same 2024 page’s “Configure to Order” section repeats those SSD tiers for apple.com configuration (M4: 512GB / 1TB / 2TB; M4 Pro: 1TB / 2TB / 4TB / 8TB, alongside memory and Ethernet options).
Memory (RAM) — Apple’s upgrade statement
Apple’s memory article groups Mac mini (M1, 2020), Mac mini (2023), Mac mini (2024), and later M-series entries listed there together:
“Memory is integrated into the Apple M-series chip package … and can’t be upgraded. You can configure the memory in your Mac mini when you purchase it.”
(Upgrade or install memory in your Mac mini)
That statement is about unified memory, not about publishing an SSD replacement guide. We quote it because many “Mac mini upgrade” searches conflate RAM and storage; Apple’s documented after-purchase rule for memory on these models is “configure at purchase.”
What Apple does not document here
- Apple’s Mac mini Support tech specs do not state whether the internal SSD is soldered or a user-swappable module on M1, M2, or M4.
- Apple’s memory article does not provide SSD removal steps for Apple silicon minis (it only details RAM procedures on older Intel generations, and “can’t be upgraded” for M-series memory).
- Therefore this Lab page omits any DIY internal SSD swap instructions and omits soldered-vs-modular claims from teardowns or forums.
If you need a larger boot volume than you ordered, options that stay within Apple’s published material are: choose a higher SSD tier when buying, add external storage (USB/Thunderbolt drives — see Apple’s Mac storage docs for your macOS version), or contact Apple / an Apple Authorised Service Provider about service parts.
External storage (related)
For moving files onto USB / external drives from Apple devices, Apple documents connectors and formats in the iPhone guides we summarise separately: How to save iPhone photos to a flash drive. On Mac, use the Mac User Guide sections for connecting storage devices for your macOS release (linked from Apple Support).
FAQ
Can I upgrade Mac mini M4 SSD myself according to Apple? Apple’s public tech specs list M4/M4 Pro SSD sizes as configure-to-order options (2024 specs). Apple does not publish a user SSD-install guide for that model on the memory/support pages cited above. This page does not add unofficial steps.
Is Mac mini memory upgradable on M1 / 2023 / 2024? No — Apple says unified memory is integrated into the M-series package and can’t be upgraded; configure it when you buy (Apple).
