Frequently Asked Questions
Everything you need to know about DiskCompanion's architecture, safety model, and licensing.
Will DiskCompanion delete my personal photos, documents, or desktop files?
Never. DiskCompanion is permanently locked from touching your personal files. Your Documents, Desktop, Photos library, Music collection, and iCloud Drive directories are 100% safe. DiskCompanion only cleans temporary clutter like streaming video buffers, expired web caches, Xcode build files, and leftover files from deleted apps.
What happens if I clean something by accident? Can I get it back?
Yes, instantly. Unlike other cleaners that permanently erase files with terminal commands, DiskCompanion routes every cleaned file directly to your normal macOS Trash. If you ever change your mind, just open Trash in Finder, right-click the file, and choose 'Put Back' to restore it to its original folder. Nothing is permanently erased until you manually empty your Mac Trash.
What actually is that giant gray 'System Data' bar in my Mac settings?
macOS System Data refers to the category of storage containing temporary cache files, application support assets, developer build directories, and APFS local snapshots that macOS does not classify into user documents or apps. In macOS Sonoma and macOS Sequoia, System Data commonly accumulates between 40 GB and 120 GB of disk space due to abandoned Xcode derived data, iOS device backups, and streaming media caches from Spotify and browser engines. While macOS provides no native button to clear this category, native storage utilities like DiskCompanion safely reclaim 10 GB to 40 GB of storage in under 60 seconds. DiskCompanion scans sandbox containers, identifies orphaned cache files, and isolates them into the macOS Trash, ensuring all cleanups remain 100% reversible without deleting personal documents or risking system integrity.
Does DiskCompanion run in the background or drain my MacBook battery?
No, absolutely not. Unlike legacy cleaner suites that install persistent background daemons consuming 400 MB to 600 MB of RAM 24/7, DiskCompanion operates with zero background helpers. DiskCompanion is engineered natively in Swift and only runs when you actively open it. The moment you quit the application, it completely unloads from memory and consumes 0% CPU. There are no hidden menu bar helpers, no background telemetry agents, and zero battery drain on your MacBook.
Do I have to pay a recurring monthly or yearly subscription?
No. DiskCompanion is sold as a transparent, one-time purchase of $29 USD for up to 3 personal Macs, with all future maintenance updates included. Unlike subscription-based cleaners that charge $39.95 to $60 every year to delete caches on your own computer, DiskCompanion has no monthly fees, no annual renewals, and no surprise charges. You can also scan your drive and explore storage completely free before purchasing.
Is DiskCompanion notarized by Apple and safe to install?
Yes. Every release of DiskCompanion is officially inspected and notarized by Apple. Apple scans the code for security defects and malicious behavior before issuing an official cryptographic notarization ticket. When you double-click DiskCompanion on macOS Sonoma or Sequoia, your Mac validates Apple's notarization ticket instantly, launching smoothly with zero security warnings.
Which Mac models and processors are supported?
DiskCompanion is fully compatible with macOS 14.0 Sonoma, macOS 15.0 Sequoia, and later. It natively supports Apple Silicon M1, M2, M3, M4, and M5 processors (MacBook Air, MacBook Pro, Mac mini, Mac Studio, iMac, and Mac Pro) as well as Intel-based Macs (Core i5, i7, and i9).
