Frequently asked

The questions we hear most. Don't see yours? Email us.

Does Holm send my photos to the cloud?
No. Holm is local-first: it copies and organises your photos and videos onto drives you own. Nothing is uploaded, and there's no subscription. Optional, anonymous usage analytics are off by default — you choose whether to turn them on.
Which Macs does Holm support?
Holm runs on macOS 14 (Sonoma) and later, on both Apple Silicon and Intel Macs.
What file types can Holm import?
Photos (JPEG, HEIC, PNG), camera RAW (ARW, CR3, NEF, DNG, RAF, ORF, RW2), and video (MP4, MOV, INSV, and more). RAW + JPEG pairs are kept together automatically.
What does "verified" backup actually mean?
Holm doesn't just copy your files — after writing each one, it re-reads the copy and compares a SHA-256 checksum byte for byte. Only once every copy on every drive is verified whole does Holm tell you it's safe to eject the card. Your originals are never touched before a verified copy exists.
A drive is unplugged and some days show "connect drive" — is something wrong?
No — that's expected. Holm remembers everything in your libraries even when a drive is offline, so the calendar still shows those days. A tile that reads "on drive X — connect to view" just means the file lives on a drive that isn't plugged in right now. Reconnect that drive and the thumbnails come back on their own. If a shot is mirrored to more than one drive, connecting any one of them is enough.
How do I report a bug or request a refund?
Email [email protected] with a short description and your macOS version. For bugs, attaching a diagnostics report (from Help & Feedback in the app) helps us a lot — it's redacted and never includes your photos. Purchases made on the Mac App Store are refunded by Apple via reportaproblem.apple.com.
