DiskMount installation and permissions

简体中文

Before you install

Download DiskMount only from the official GitHub Releases page. Version 0.2.9 is self-contained and does not require Homebrew, Xcode, or a separate anylinuxfs installation.

The current package is signed with the developer's Apple Development certificate, but it is not signed with a Developer ID Application certificate and is not Apple-notarized. A Mac that downloads the DMG from the internet may therefore block the first launch. This Gatekeeper approval is separate from the disk permissions requested after DiskMount starts.

Normal installation

  1. Download DiskMount-0.2.9-macOS26.dmg and its .sha256 file.

  2. Optionally verify the download in Terminal:

    cd ~/Downloads
shasum -a 256 -c DiskMount-0.2.9-macOS26.dmg.sha256

  3. Open the DMG and drag DiskMount.app to Applications.

  4. Open DiskMount from Applications. Its controls remain in the macOS menu bar.

If macOS blocks the app

Do not disable Gatekeeper globally. Use the per-app exception provided by macOS:

  1. Try to open DiskMount once and close the warning.
  2. Open System Settings → Privacy & Security.
  3. Scroll to Security and find the message that DiskMount was blocked.
  4. Click Open Anyway. macOS normally shows this button for about one hour after the blocked launch.
  5. Authenticate with the Mac login password, review the warning, and choose Open.

macOS then remembers DiskMount as an exception on that Mac. On organization-managed Macs, an administrator or MDM policy may still prevent this override. See Apple's Open apps safely on your Mac guidance.

Avoid instructions that permanently disable Gatekeeper or indiscriminately remove quarantine attributes. Download a new copy from the official release if the checksum fails or macOS says the app is damaged.

Permissions after launch

The following approvals serve different purposes:

  1. Administrator authorization: NTFS read/write mounting, stopping its disk service for safe eject, and failure recovery need elevated access. DiskMount reuses a still-valid authorization session and asks again only when macOS authorization has expired. The password is passed transiently to macOS sudo; DiskMount does not store, log, or upload it.
  2. Full Disk Access: enable System Settings → Privacy & Security → Full Disk Access → DiskMount.
  3. Removable Volumes: when macOS shows this switch, enable System Settings → Privacy & Security → Files & Folders → DiskMount → Removable Volumes.
  4. Fully quit and reopen DiskMount after changing either privacy permission.

DiskMount does not format, erase, repartition, or convert disks. NTFS read/write changes only the active mount method.

DiskMount contacts GitHub's public latest-Release API when it starts and when the user manually refreshes. This check sends no disk contents or administrator password, and it never downloads or installs an update automatically.

Commercial distribution status

Version 0.2.9 is a development-signed community release. Warning-free public distribution requires a Developer ID Application certificate, hardened-runtime signing of the app and all bundled helpers, Apple notarization, and a stapled notarization ticket.
