Support

macOS requires you to turn on file system extensions yourself:

• Open Volmora and click Open System Settings…, or open System Settings manually.
• Go to General › Login Items & Extensions, then click the ⓘ button next to File System Extensions.
• Turn on Volmora and click Done.

Volmora shows the extension status in the app, so you can confirm it’s active.

• NTFS (Windows) — read and write. Volumes open read-only by default; writing is enabled after you confirm it.
• ext2, ext3 and ext4 (Linux) — read-only.
• XFS (Linux) — read-only.

APFS, Mac OS Extended, exFAT and FAT drives are handled by macOS itself. Volmora lists them for convenience, but they never need the extension or a purchase.

Only supported filesystem features and clean volumes are accepted. Volmora does not unlock encrypted volumes, assemble Linux storage stacks such as LVM or RAID, or repair filesystems and replay recovery journals. A supported format name alone does not guarantee compatibility with every volume.

Btrfs, SquashFS and ReFS are being evaluated for future support. They are not available. Broader XFS compatibility is also on the roadmap.

The current build targets macOS 15.4 or later. Runtime testing so far has covered macOS 26.6.2 on Apple silicon; older macOS versions and Intel Macs still require qualification before we claim support. Check the final App Store listing when available.

Volmora uses Apple’s FSKit framework. You enable the file system extension in System Settings, but do not need to run the app as root, install a privileged helper or enable Reduced Security.

• Check in Volmora that the extension is enabled and that you have an active plan.
• Check whether the drive is listed in Volmora and whether it reports an unsupported format or a mount error.
• In Finder, open Settings › Sidebar and make sure External disks is checked.
• Before reconnecting or changing a cable, normally unmount every volume on that physical device. Never disconnect a mounted volume or a failed session just to retry.

If it still doesn’t mount, export diagnostics (see below) and send them to us.

NTFS: volumes open read-only by default to protect your data. Enable write access in Volmora and confirm it when you need to change files on the drive.

ext2, ext3, ext4 and XFS: these are read-only in the App Store edition. You can browse, open and copy existing files, but cannot modify the source volume. Premium does not enable an unsupported write mode — copy a file to a writable destination before editing it. Experimental Linux write functionality in separate development builds is not a feature of this edition.

The sandboxed App Store edition cannot manually remount an already attached physical device. This action shows instructions; it does not mount anything. For removable devices, normally unmount all volumes first, then reconnect so macOS can attempt automatic mounting through the enabled extension.

A purchase confirms access to supported features, not that a volume has mounted. Check the actual status in Volmora. If unmount fails, stop using the volume and preserve diagnostics rather than disconnecting it.

Turn on Show disk images in Volmora’s Settings. It is off by default. This reveals attached images; it does not attach image files or add support for unknown formats.

Recognized supported images can offer Mount read-only. If an image needs reconnecting, normally unmount its volumes and detach it before reopening it. Do not detach a mounted or failed session.

• On Windows, always use Safely Remove Hardware before unplugging the drive.
• Windows Fast Startup and hibernation can leave a drive in an unfinished state. Fully shut down Windows (or turn off Fast Startup) before moving the drive to your Mac.
• If Windows reports problems, preserve a backup before considering repair using the originating system’s tools. Volmora is not a recovery or repair utility.

Use normal unmount or eject and wait for successful completion. Every volume on the same physical device must be unmounted before disconnecting it. A single volume’s successful unmount does not prove that the whole device is ready to remove.

If unmount fails, close applications using the volume and preserve diagnostics. Do not force-disconnect or treat an emergency detach as a clean unmount.

Open Volmora’s Settings and click Export… next to Export diagnostics. Volmora describes the included information — volume names, device identifiers, disk space, app and macOS versions, logs and session status — and asks you to confirm. The exporter does not copy files from your drives or upload the archive automatically. Review the archive for sensitive names or paths before choosing to email it. See the Privacy Policy for details.

• 7-Day Pass — one-time purchase, access to supported features for seven days, does not renew.
• Monthly and Yearly — auto-renewing subscriptions.
• Lifetime — one-time purchase with no expiry.

These are the planned purchase options for release. All plans unlock the same supported features; none adds write support to a read-only provider. Check availability and current local prices in the app’s purchase screen when the release is available.

Make sure you’re signed in to the App Store with the same Apple Account you used to purchase, then choose Restore Purchases in Volmora. Purchases are tied to your Apple Account, not to a specific Mac.

Subscriptions are managed by Apple. Open the App Store, click your name, then Account Settings › Subscriptions › Manage, or go to apps.apple.com/account/subscriptions. You keep access until the end of the current billing period.

Refund requests are handled by Apple at reportaproblem.apple.com. You are also welcome to contact us for technical help; contacting support first is not required.
