052eb912b4cb83efneeds manual clarification.Reason: Investigated Memmy v1.2.3 → v1.2.4 update failure. Verified server side is healthy:
GET https://api.memmy.cn/api/memmy/desktop/latestreturns a well-formed v1.2.4 record for bothdarwin-arm64-cn-signedandwin32-x64-cn-signed, and the OSS DMG/EXE download URLs respond 200 with correct Content-Length/MD5. The literal error "安装更新失败，请稍后再试。" (settings.about.updateInstallFailed) is set from three code paths inupdate-coordinator.tsx: thedownloadUpdatecatch (download/staging failed), theinstallPreparedUpdatecatch (open-installer threw), and the missing-bridge fallback (web only). Combined with "三四次重试均失败", the most probable client-side causes are: (a) macOS stage/install helper failscodesign --verify -Ragainst the v1.2.4 bundle because its signing TeamIdentifier differs from the v1.2.3 install (helper deletes DMG and re-throws, user retries, same loop); (b)codesign -dvon the currently runningMemmy.appcan't produce a TeamIdentifier (translocated bundle / broken sealed resources); (c) WindowsGet-AuthenticodeSignaturepublisher mismatch between installed exe and v1.2.4 installer; (d)/Applications/Memmy.appis missing soresolveMacUpdateDestinationAppPath()returns null. No code changes yet because a speculative fix could regress other upgrade paths on the same release.syzsunshine219 commentedon Oct 28, 2026
This issue has been fixed in v1.2.401. You can download the latest installation package. If you are unable to update, you can download the installation package from the official website and overwrite the existing installation with the latest package
