'The following disk images couldn't be opened' Error
Although not as popular as it was in the past, the disk image is still a common file format used on Mac systems. Its main characteristic is that it acts as a physical disk and can be mounted in Finder. Software developers opt for a disk image format when they want to exert more control over the way their product is presented when the image is executed. One particular error that users can encounter while trying to access a downloaded disk image is 'The following disk images couldn't be opened.' The message signals that the image might have become corrupted, most likely due to problems during the download process.
Dealing with the 'The following disk images couldn't be opened' Error
The first thing to do after seeing the 'The following disk images couldn't be opened' message is to try to download the file again. If redownloading doesn't help and the error is still present then move on to varying the disk image through your Mac's Disk Utility.
- Open the 'Applications' folder.
- Locate and launch 'Disk Utility.'
- Select 'Images' from the menu and click on 'Verify.'
- Navigate to the disk image that is causing the error.
- Select it and press 'Verify.'
- Wait for the process to complete and act depending on the outcome:
If the disk image was verified successfully, then try to mount and open it again.
If the verification failed and redownloading doesn't help, then consider contacting the developer of the application.
