Why Your .DMG File Is Not Opening on Mac
Some users noted that they cannot open the .dmg file on Mac after updating to Catalina, but there are also those who encountered this error when running an older version of macOS. This means that the problem is not unique to Catalina but it is something that affects the entire macOS system.
Here are some of the possible reasons why some users are having trouble opening DMG files:
- If your Mac is running Catalina, check the version of the app you are trying to open. Catalina no longer supports 32-bit apps. So if you’re trying to download and install a 32-bit app, then you might not be able to install it on Catalina.
- If you have poor or unstable internet connection, it is possible that the file was not downloaded completely, resulting in errors when accessing the file.
- If you downloaded the file from an untrustworthy source, it might be a fake DMG file or it could be loaded with malware.
- It is also likely that the DMG file you downloaded is corrupted. An interrupted download process and malware infection are the two leading causes of file corruption.
Hence, before you start the troubleshooting process, here are some things you need to consider:
- Download the file once again using a different internet connection. Try using a wired connection if possible.
- Scan the file for malware infection, especially if the file was downloaded from an untrustworthy source.
- Download the file from another source. If the app is not available on the Mac App Store, visit the developer’s website and download the installer from there instead.
- If you’re running macOS Catalina, make sure that you are downloading the 64-bit version of the app.
