The truth is: because the two systems are fundamentally different. But there are workarounds.
With the introduction of M-series chips, modern Macs use the same ARM architecture as iPhones. ipa to dmg
An archive format (essentially a renamed ZIP) used for iOS/iPadOS apps. It contains the application bundle ( .app ) within a "Payload" folder.
DMG files are not archives in the same sense as IPA; they are disk images that macOS treats like a virtual hard drive. Double‑clicking a DMG mounts it, revealing its contents. Dragging the enclosed .app to Applications installs the software. | Step | Action | Technical Operation |
Method 1: The Manual Extraction and Packaging Route (Recommended)
Developers often package iOS builds into DMGs for clean, read-only storage on local servers. | | 4 | Packaging | Use hdiutil
unzip app.ipa -d app_extracted mv app_extracted/Payload/*.app . codesign -f -s "Apple Development" MyApp.app hdiutil create -format UDZO -srcfolder MyApp.app MyApp.dmg
Since .ipa is a zip archive and .dmg is a disk image, the conversion is effectively a process of and re-packaging .
Double-click the .zip file to extract it. You will see a folder named Payload .
