how to check mac storage

To check storage on a Mac, open the Apple menu, go to System Settings (or About This Mac on older versions), and view the Storage section for a visual breakdown of used and available space.

Basic method: System Settings

This is the easiest way on modern macOS (Ventura, Sonoma, Sequoia):

• Click the  Apple menu in the top-left.
• Select System Settings.
• In the sidebar, click General → Storage.
• You’ll see how much space is used, how much is free, and a bar showing categories like Apps, Documents, System Data, and more.

On some older macOS versions:

• Click  → About This Mac → Storage to see a similar bar and numbers.

Finder methods (quick checks)

If you like using Finder, there are a couple of handy options.

• In Finder, select Macintosh HD in the sidebar, then press Command + I (or right‑click → Get Info) to see capacity, used, and available space.

• If your disk shows on the Desktop, click its icon and press Space to open Quick Look and see storage info at a glance.

These give a general overview and are good for quick checks.

Disk Utility for more detail

Disk Utility shows each disk and volume, which is useful if you have external drives or multiple partitions.

• Open Finder → Applications → Utilities → Disk Utility.
• Select your startup disk (usually Macintosh HD) in the sidebar.
• On the right, you’ll see total capacity, used space, and free space.

This is more technical but reliable for confirming what’s actually available.

Terminal method (for power users)

If you’re comfortable with the command line, Terminal can show all volumes at once.

• Go to Applications → Utilities → Terminal.
• Type df -h and press Return.
• Look for the line with /System/Volumes/Data; the “Avail” column shows how much space you have left.

This method is precise and works even when some graphical tools are slow or glitchy.

How to check what’s using space

Once you know you’re low on space, you can see what’s taking it:

• In System Settings → General → Storage, look at the colored bar and categories (Apps, Documents, Photos, System Data, etc.), then click each category for cleanup options.

• Some guides suggest sorting Documents by large files and cleaning Downloads, videos, and old message attachments to reclaim space quickly.

TL;DR: For most people,  → System Settings → General → Storage is enough; use Finder, Disk Utility, or Terminal only if you want more technical detail or have multiple drives.
