BEST ANTIVIRUS FOR MACS — CYBERGUY PICKS 2025
Use a third-party app for deep duplicate scanning
Third-party apps are a great option for more advanced duplicate detection (including photos stored outside the Photos app). If you have antivirus software, some offer a duplicate file finder that detects duplicate images, videos, and files stored on your Mac. Once installed, you can scan your folders, review the detected duplicate files, select the ones you want to delete and click “Remove” to free up space. (We always encourage you to back up your system before doing this if you ever need to restore any files.) Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.
Bonus tip: Clear out old iCloud photo duplicates
If your Mac syncs with iCloud Photos, any duplicates removed from the Mac will also be deleted from iCloud. However, if you keep a lot of photos outside the Photos app, running a strong antivirus software on your Mac storage can help clear space efficiently.
Empty trash
When you delete something on your Mac, it remains in the Trash folder and continues to occupy storage space until you empty the Trash. The Trash does not automatically hold files for a specific number of days unless you have enabled the “Empty Trash Automatically” feature, which can be set to remove items after 30 days. If you need to free up space immediately, emptying the Trash is a good first step.
- Right-click the Trash icon in the dock.
- Select Empty Trash.
- Confirm the deletion by clicking Empty Trash.

Delete unnecessary apps
After clearing the Trash, the next step is to delete unnecessary apps. Unused applications take up valuable storage space and can slow down your system. Removing them will free up space and improve performance.
- Open Finder.
- Click Applications.
- Click and drag unused applications to the Trash icon in the dock.
- Empty the Trash by right-clicking on the Trash icon in the dock and selecting Empty Trash.
- Confirm the deletion by clicking Empty Trash.

Delete the files you don’t need
Take some time to go through your files and delete anything you no longer need. Old documents, large video files, duplicate photos, and outdated downloads can take up a surprising amount of space. If you are unsure about deleting certain files, move them to an external drive or cloud storage before permanently removing them.
- Click the Apple menu.
- Then select System Settings.
- Click General and select Storage.

Always exercise caution when deleting files and ensure you have a backup before making significant changes to your data.
Transfer files to external storage
- Choose the right external drive: Opt for an external hard drive or solid-state drive (SSD) that suits your needs. SSDs offer faster speeds and better durability, while HDDs provide larger capacities at lower costs.
- Transfer files: Connect your external drive, copy your files to it, and verify that all files are successfully transferred.
- Delete original files: After verifying the transfer, delete the original files from your Mac to free up space. Use Finder to move files to Trash and then empty it.
Consider cloud storage
Use services like Google Drive, Dropbox or Microsoft OneDrive to store large files and free up local storage. These services offer automatic syncing and backup features.
