OS X Lion installer 'cannot be verified' after download. After downloading the OS X Lion installer from the Mac App Store, some people are finding the installer cannot be verified and will not run.
Whenever Apple releases an update for High Sierra, many Mac users will rush to download it. Because of that, Apple’s servers slow down. Thus, your first course of action should be to check the System Status page of Apple and see macOS Software Update to find out if there are problems. How to Install Mac Software 1. Double-click the application file you've downloaded from the Internet. If you get an error message that says the program 'can't be opened because it wasn't downloaded.
Most savvy computer users know that it's important to be vigilant about where they download software from, but few stop to verify that the file they received is the file they were supposed to receive. This can be a critical final step in preventing malware infections of the sort we saw with Transmission.
Developers often post checksums or hashes alongside the download links for their projects to facilitate this kind of verification. Broadly, a checksum is the result of a mathematical calculation run on a particular file — if the file hasn't been altered, the checksum you calculate will match the checksum provided by the developer.
It's still not clear exactly how the infected download made it onto Transmission's website, but those who received it early in the process have reported that the bad file's checksum didn't match the checksum provided by the Transmission team. If they had verified the checksum before installing, they would've known something was amiss.
It's worth mentioning that this is not an infallible process: if a website is compromised, the attacker could've easily changed the checksum as well. Still, it's a useful — and very quick — precaution to take.
Important note: For most people, files will be automatically placed in their downloads folder. To access this folder in Terminal, use ~/Downloads.
SHA-1 is the checksum format used by Apple, among many others. To find the SHA1 checksum of a file, open a Terminal window and enter the following:
If your file is called Paint.dmg and it's in the Downloads folder, it would look like this:
The result should look like this:

SHA1(/Users/username/Downloads/Paint.dmg) =07272d863ab77113e38e6ce3878c2162feb4893e
The series of letters and numbers in the result is the checksum: just compare it to the checksum provided by the developer.
Another popular checksum is SHA256, the kind used by Transmission's team. To verify it on a Mac, use:
Verifying an MD5 checksum
MD5 is no longer recommended as a checksum hash for security reasons, but some legacy programs may still use it. To verify:
