Need a RAM upgrade for your Mac mini (2018)? We carry out this work in-house at our London workshop, with a fixed quote before we start.
The A1993 uses two DDR4 SO-DIMM slots, supporting up to 64GB. To reach them we slide out the logic board. We fit matched, tested modules; this is a very worthwhile upgrade on an 8GB machine.
About this model: The 2018 space grey Mac mini (A1993) has Intel processors, the T2 security chip, soldered storage and socketed SO-DIMM memory. It was sold until 2023, so plenty are still in service.
Signs it needs a RAM upgrade
- Memory pressure
- Slow with multiple apps
- Faulty module
- Memory not recognised
How we do it
We read your exact model identifier first, because Mac memory is fussy about speed and type, and the wrong module can cause beeps at start-up or random crashes. We fit matched pairs where the model benefits from dual-channel memory.
After fitting we run an extended memory test and check that the full amount shows in System Information, so there are no surprises later.
At a glance
| Years | 2018–2023 |

| Storage | Soldered to the logic board |
| Memory | Socketed, upgradeable |
| Power / charging | Internal mains power supply |
Before you bring it in
Open Activity Monitor and look at the Memory tab: if Memory Pressure is often yellow or red, more RAM will help. Screenshot it and bring it along.

We give you a fixed quote for your exact model after a free initial assessment, before any work starts. All prices are subject to inspection, and nothing is done without your approval.
Questions we’re often asked
Will I lose my files?
No. We clone or back up your data before any upgrade and check everything is in place afterwards.
Is it worth upgrading this model?
For most owners it is. An upgrade costs a fraction of a new Mac, and we’ll say plainly if your particular machine has other faults that make it a poor investment.
Do I pay if you can’t fix it?
No. If the repair isn’t possible, you don’t pay for it, and the free initial assessment costs nothing.
