xattr -cr extracted/Payload/YourApp.app Now we’ll wrap that .app into a disk image using hdiutil (the built‑in macOS disk image tool).

If the app crashes immediately, check Console.app for architecture errors – some iOS apps are compiled only for arm64 but require Mac Catalyst entitlements. “App is damaged and can’t be opened” This usually means Gatekeeper is blocking it. Override temporarily with:

sudo spctl --master-disable # turn off assessment (not recommended long-term) Or simply right‑click the app in Finder and choose – then confirm the warning. The app launches but the window is tiny (iPhone size) That’s normal. On a Mac, iOS apps run in a scaled window unless the developer added Mac‑specific size classes. You can force full‑screen mode via Cmd + F or use a tool like Rectangle to resize. What about Intel Macs? iOS apps do not run on Intel Macs (unless the developer compiled a separate Mac binary). This DMG will only launch on Apple Silicon machines. Automate It (One-Liner Script) Save this as ipa2dmg.sh :

chmod +x ipa2dmg.sh ./ipa2dmg.sh YourApp.ipa Converting an IPA to a DMG is straightforward once you understand that an IPA is just a zip containing a .app bundle . The real challenge isn’t the conversion – it’s whether the iOS app will behave well on macOS.

While iOS apps are distributed via .ipa (iOS App Store Package) and macOS apps often live inside .dmg (Disk Image) files, converting between them isn’t a simple “rename the extension” process. However, with a few terminal commands and a basic understanding of macOS app bundles, you can package an iOS app for direct installation on a Mac.

If you’ve ever built an iOS app that also runs on Apple Silicon Macs (or you’re dealing with legacy enterprise deployments), you might have asked: “How do I turn my .ipa file into a .dmg?”
