The MacBook Neo starts with 256 GB of storage, and like every Apple silicon Mac, that storage cannot be upgraded later. 256 GB is enough for many people, but it fills faster than the number suggests, and the “storage almost full” warning tends to arrive months after purchase, not on day one. Here is where the space goes and how to keep it.
Why 256 GB feels smaller than it is
- macOS takes its share first. The system, its recovery data and System Data use a sizeable part of the disk before you install anything. Check yours in System Settings, General, Storage.
- macOS needs free space to work. Updates, swap and caches all need room. A Mac with only a few gigabytes free gets slow, and large macOS updates may refuse to install until you clear space.
- Some things grow quietly. Photos and iCloud Drive keep local copies, Messages keeps every attachment, and apps cache more the more you use them.
The Neo has 8 GB of memory, so it moves memory to the disk (swap) sooner than a Mac with more. That swap needs free space, which is one more reason to keep a healthy margin on a small disk.
Where the space usually goes
In rough order of how often it is the culprit:
- Photos. A Photos library with full-resolution originals is often the largest single item.
- Downloads. Installers and files you opened once.
- Messages attachments. Years of photos and videos from chats.
- iPhone backups, if you back up your phone to this Mac.
- App caches, which rebuild as you use apps.
- Developer tools, if you code: Xcode alone can take tens of gigabytes.
The settings that free the most, for free
These are built into macOS and cost nothing:
- Optimize Mac Storage for Photos. In Photos, Settings, iCloud, choose Optimize Mac Storage. Full-resolution originals stay in iCloud and the Mac keeps smaller copies. Needs enough iCloud storage for your library.
- Optimize Mac Storage for iCloud Drive. In System Settings, click your name, then iCloud, and turn on Optimize Mac Storage (under iCloud Drive on recent macOS), so files you have not opened in a while live only in iCloud until you need them.
- Empty the Trash automatically after 30 days, from the Recommendations in Storage settings.
- Keep Messages for one year, not forever, in Messages Settings, General, if you do not need old chats.
A monthly ten-minute routine
- Sort Downloads by size and delete what you no longer need.
- Check System Settings, General, Storage for the largest categories.
- Find the largest folders with a tool that sizes everything at once. Our guide on what you can delete says which folders are safe.
- Remove apps you have not opened in months, along with their leftover files.
- If you back up your iPhone to the Mac, delete backups of devices you no longer own.
Should you get an external drive?
For a small disk, an external SSD is the cheapest extra space. It suits large media libraries, video projects and archives. Keep apps and your active work on the internal disk, which is faster and always there.
Is 256 GB enough?
For browsing, email, documents, streaming and a moderate photo library kept in iCloud, usually yes. If you edit video, keep a large music or photo library locally, play big games or develop software, plan for an external drive from the start.
How DiskAtlas and Kempt help
DiskAtlas shows the whole disk as a map, labels what each folder is and whether it is safe to clear, and moves nothing until you review the list. On a small disk, its largest-items list is usually all you need. Kempt does the monthly routine above in one place: safe-to-clear caches, old downloads, idle developer projects and leftovers of removed apps, each with a reason it is listed. Only what you tick is cleared.
