imapSyncGUI v0.1.0

First public Windows x64 installer for imapSyncGUI.

• First public Windows x64 NSIS installer (unsigned).
• The application bundles the imapsync runtime; end users do not need Perl, imapsync, Strawberry Perl, or any other runtime installed.
• The installer is currently unsigned, so Windows SmartScreen / Microsoft Defender may show a warning.
• If the file was downloaded from this official GitHub Release, you can choose "More info" -> "Run anyway".

Note: this is an unsigned build; no Authenticode certificate is applied.

imapSyncGUI v0.1.0 — E2E Test Build 3

imapSyncGUI v0.1.0 — E2E Test Build 3

Pre-release end-to-end test build from the current verified main branch.

• Commit: 411dae35a571a7e190d43f6be80a342ec4875a52 (TASK-014)
• Included fixes:
  • macOS arm64 Net::SSLeay / OpenSSL portability — the bundled runtime's
    OpenSSL dylibs are now embedded in the PAR archive and referenced via
    @loader_path, so the runtime no longer depends on Homebrew OpenSSL
    (/opt/homebrew) at run time (ADR-018).
  • Improved migration failure UX — typed failure categories, a concise
    user-facing failure message, and raw loader diagnostics moved to a secondary
    "Technical details" section.

imapSyncGUI-0.1.0-mac-x64.dmg	Intel (x86_64)	55e240123ef5d66f3e666d7eb8a02ecbc6ba3db00164b2f8440bd16492bbe16a

The arm64 DMG comes from the successful native Apple Silicon CI run
(https://github.com/marijustechin/imapsyncgui/actions/runs/34590679495) and was
independently checksum- and architecture-verified. The x86_64 DMG was built and
verified locally on macOS x86_64 (runtime validation, host-isolation self-test,
and packaged smoke test).

Status

• Unsigned / not notarized. The .app is ad-hoc signed only; macOS
  Gatekeeper will require manual approval on first launch.
• Not production-ready. This is an end-to-end test build.

imapSyncGUI v0.1.0 — E2E Test Build 2

imapSyncGUI v0.1.0 — E2E Test Build 2 (DMG, ad-hoc signed)

Pre-release build for clean-machine end-to-end verification (TASK-010). This is
not a production release.

Which file do I download?

Pick the DMG that matches your Mac. The filename always names the architecture.

Your Mac	CPU	Download
Apple Silicon (M1/M2/M3/M4…)	arm64	imapSyncGUI-0.1.0-mac-arm64.dmg
Intel Mac	x86_64	imapSyncGUI-0.1.0-mac-x64.dmg

How to check (no technical knowledge needed):

• GUI: Apple menu → About This Mac. The "Chip" line (Apple silicon) or
  "Processor" line (Intel) tells you which.
• Terminal: run uname -m:
  • arm64 → Apple Silicon → download the arm64 DMG
  • x86_64 → Intel Mac → download the x64 DMG

Downloading the wrong architecture is a common cause of "the app is damaged"
errors — please verify the architecture before launching.

Signing / notarization

• The app is ad-hoc signed but not Developer ID signed and not
  notarized (no Apple Developer Program credentials).
• A Gatekeeper warning is expected on first launch. The normal user action is
  System Settings → Privacy & Security → Open Anyway (or Control-click → Open),
  depending on the macOS version.
• This release fixes a packaging defect in v0.1.0-e2e.1 where the arm64
  bundle was only linker-signed, causing Gatekeeper on Apple Silicon to
  misreport it as damaged ("move to Trash") instead of showing the normal
  "unidentified developer" approval flow.

Installation (no terminal required)

1. Download the correct DMG for your Mac.
2. Open the DMG.
3. Drag imapSyncGUI to Applications.
4. Launch it from Applications.
5. If macOS blocks the app, use the normal Privacy & Security approval.

Checksums

SHA256SUMS.txt accompanies this release. Verify with
shasum -a 256 -c SHA256SUMS.txt.

Runtimes

The bundled imapsync runtimes are self-contained; the end user needs no
Homebrew, MacPorts, Perl, CPAN modules, or Rosetta.

• x86_64: official imapsync_bin_Darwin_x86_64 (imapsync 2.314).
• arm64: self-built PAR::Packer binary (imapsync 2.324).

Build

• Source commit: 2a06298dfcf3667a3c2f2265211881f2be371a6c
• pnpm verify passes (192 tests).
• x86_64 DMG built on the developer's x86_64 macOS 14.8.7: hdiutil verify
  passes, DMG mounts, app copied from the DMG retains x86_64 architecture,
  packaged smoke passes, app launches.
• arm64 DMG built by native arm64 CI (macos-15 arm64 runner): hdiutil verify
  passes, DMG mounts, app copied from the DMG retains arm64 architecture,
  packaged smoke passes, app launches.

imapSyncGUI v0.1.0 (E2E test build, unsigned)

imapSyncGUI v0.1.0 — E2E test build (unsigned)

Pre-release build for clean-machine end-to-end verification (TASK-010). This is
not a production release.

Signing / notarization

• Unsigned and not notarized (no Apple Developer Program credentials).
• On first launch macOS Gatekeeper is expected to block the app or warn about an
  unidentified developer. The normal user action is System Settings →
  Privacy & Security → Open Anyway (or Control-click → Open), depending on the
  macOS version.
• Signing/notarization is optional, client-funded release hardening.

Runtimes

The bundled imapsync runtimes are self-contained; the end user needs no
Homebrew, MacPorts, Perl, CPAN modules, or Rosetta.

• x86_64: official imapsync_bin_Darwin_x86_64 (imapsync 2.314).
• arm64: self-built PAR::Packer binary (imapsync 2.324, Perl 5.44 embedded).

Build

• Source commit: d810921ef32f74a57316a5a97b7cb5b6e425fcbd
• pnpm verify passes (183 tests).
• x86_64 packaged smoke test passes; arm64 native CI workflow passes
  (runtime validation + host-isolation self-test + packaged smoke test + launch).

Notes

• The arm64 artifact is rebuilt per CI run and is not byte-reproducible across
  runs (embedded build timestamps), so its SHA-256 reflects this exact build.
