As a software junky who is always downloading new apps to try, one can never be too careful about verifying you’re not installing malware. One step in that process is to verify downloaded files with the checksum provided by the software provider, when they provide one. In the years since I converted to Macs from Windows, I’ve yet to find a simple-to-use, free app to verify those checksums. So, I rolled my own which I have named c3checksum. Yep. You can read all about it and download it here. If you’d like an app that has more options and complexity I also ran across Checksums which looks like an amazing option. I myself have not yet tried it but thought I’d offer it as an alternative to my own simple solution. Enjoy!
