Free Up Your Mac's Space
Practical tips to clear storage on your MacBook or iMac - from The Mac Space in Marietta, GA
Before You Buy a New Mac
A "disk full" warning doesn't mean your Mac is done. Most of the time, there are gigabytes of files you can safely remove without losing anything important. Follow these steps in order - start with the quick wins, then go deeper if you need more space.
Quick Wins - Free Up Space in Minutes
These are the fastest ways to reclaim storage on any Mac. Start here and you might be surprised how much space you get back.
Empty Trash and Downloads
Right-click the Trash icon in your Dock and choose "Empty Trash." Then open your Downloads folder (Finder > Go > Downloads) and delete anything you don't need. These two folders alone can hold 10-20GB of forgotten files.
Use Manage Storage
Click the Apple menu > About This Mac > Storage > Manage (on newer macOS: System Settings > General > Storage). This built-in tool shows exactly what's eating your space and lets you review large files, optimize storage, and empty trash automatically.
Clear Browser Cache
Safari: Settings > Advanced > Show Develop menu, then Develop > Empty Caches. Chrome: Settings > Privacy > Clear browsing data. Browser caches can quietly grow to several gigabytes over time.
Remove Old iOS Backups
If you've ever backed up an iPhone or iPad to your Mac, those backups could be taking up 5-50GB each. Go to Finder (or iTunes on older macOS), connect your device, and delete old backups you no longer need.
Offload to iCloud
System Settings > Apple ID > iCloud > Optimize Mac Storage. This keeps full-resolution photos and files in iCloud while storing smaller versions locally. Great if you have iCloud storage but your Mac's drive is small.
Clear System Logs
Open Finder, press Cmd+Shift+G, and type ~/Library/Logs. You can safely delete the contents of this folder. These are diagnostic logs that macOS regenerates as needed - they just pile up over time.
Go Deeper - Find the Big Files
If the quick wins weren't enough, these steps help you track down the files that are really eating your storage:
Sort Files by Size in Finder
Open Finder and press Cmd+F. Click "Kind" and change it to "File Size." Set it to "is greater than" and enter 500MB or 1GB. This reveals the largest files on your drive - old movies, disk images, installer files, or forgotten projects that you can move or delete.
Uninstall Apps You Don't Use
Open Finder > Applications and sort by size. Drag apps you no longer use to the Trash. For apps that came with an uninstaller (like Adobe products), use that instead. Some apps take up 5-10GB or more - GarageBand and iMovie alone can use 5-8GB if you never touch them.
Clear Time Machine Local Snapshots
Time Machine keeps local snapshots on your drive in case you need to restore files. These are normally managed automatically, but when your drive is nearly full, they can make things worse. Open Terminal and type tmutil listlocalsnapshots / to see them. macOS will eventually clean these up on its own, but if you need space now, disabling and re-enabling Time Machine clears them.
Optimize Your Photos Library
If you use iCloud Photos, go to Photos > Settings > iCloud and enable "Optimize Mac Storage." This keeps thumbnails locally but stores full-resolution versions in iCloud. If you have a large Photos library, this alone can free up tens of gigabytes.
Check for Large Mail Attachments
Apple Mail downloads and caches every attachment from your email. Go to the Manage Storage tool (Apple menu > About This Mac > Storage > Manage) and check the Mail section. You can delete large attachments without losing the emails themselves.
When DIY Isn't Enough
If your Mac is still running slow or running out of space after cleanup, there might be a hardware solution. Here's how we can help:
SSD Upgrade
Still running out of room? We upgrade Mac SSDs - get 2x or 4x the storage without buying a new Mac. Older MacBooks, iMacs, Mac minis, and Mac Studios can often be upgraded to larger drives. We clone your existing data so everything stays exactly as it is, just with more space.
Diagnostic Service
Mac still slow after cleanup? Could be a deeper issue - a failing drive, low RAM, thermal throttling, or something else. We run full diagnostics to find the real cause and give you a clear recommendation. The inspection is free.
Data Recovery
Accidentally deleted something important during cleanup? Don't panic - and don't write any new files to the drive. Bring it in as soon as possible. The sooner we look at it, the better the chances of getting your files back.
Mac Storage FAQ
Click the Apple menu in the top-left corner, then "About This Mac." On macOS Ventura and later, go to System Settings > General > Storage. On older macOS versions, click the Storage tab in About This Mac. You'll see a color-coded bar showing what's using your space - apps, documents, photos, system data, and more. Hover over each section for details.
The most common reason: you deleted files but didn't empty the Trash. Files in the Trash still take up space until you permanently empty it. Other culprits include Time Machine local snapshots, cached files, and "System Data" - a category that includes caches, logs, and temporary files that macOS manages. If you recently deleted a lot and space didn't change, try restarting your Mac - sometimes macOS needs a reboot to release cached storage.
"System Data" (called "Other" on older macOS versions) includes caches, logs, temporary files, Spotlight indexes, swap files, and Time Machine local snapshots. It's normal for this to be 10-30GB. If it's significantly larger, try clearing browser caches, removing old Time Machine snapshots, and restarting your Mac. If System Data keeps growing beyond 50-60GB and you can't figure out why, bring it in - we can diagnose what's filling up that category.
It depends on the model. Older MacBook Pros (2012-2015), MacBook Airs (2013-2017), iMacs (2012-2020), Mac minis, and the Mac Studio M1/M2 can have their SSDs upgraded to larger drives. Most 2016-2020 MacBook Pros and all Apple Silicon MacBooks have soldered storage that can't be replaced. Not sure about your Mac? Bring it in or give us a call - we'll tell you what's possible for your specific model.
For most people, 256GB is tight and 512GB is comfortable. If you work with photos, video, or music, 1TB or more is worth it. A good rule of thumb: you want at least 15-20% of your drive free at all times for macOS to run smoothly. If you're constantly managing storage and deleting things to make room, it's time to either clean up aggressively or upgrade the drive.
