Speed up your PC in minutes
Sometimes your computer may display an error code indicating that the dmg checksum is invalid. This problem can have several causes. It is possible that your download has been corrupted. I would recommend deleting the recently downloaded file and trying to download it again. If you are still having this problem, you can try downloading this file using a different ISP.
Why is my disk image file showing invalid checksum?
About the development potential. a disk image file is usually the sum of all parts of that file. The program then checks the sum to make sure that the specified sum is indeed an image. If it is missing, it will report ” “invalid checksum”. If you downloaded it from a website, something might have been corrupted during the download and I suggest you try again.
Apparently no one has responded so far. To log in again, just ask a newbie question.
What does a checksum error mean on a Mac?
A checksum error indicates that the file left behind by Apple is different from the file received on your computer. This usually means that the file type was corrupted in transit. But it could also indicate the right hardware issue with your computer and/or somewhere on your network.
