Be sure not to try launching the app from within bundle. Only launch from LaunchPad, the Applications Folder, or your Dock if you’ve placed it there. If that still doesn’t work, read on...

You can just hit the up-arrow key in the terminal to repeat the last command after the new download, but be sure to delete the bad download first or sometimes the file gets renamed with a ‘-1’ or something similar after it and the command will give you a “no such file or directory” error.

What you did was run a command to calculate the hash of the already downloaded file and then compare it to the one it was supposed to calculate. If they matched, it spat the hash back at you. If they didn’t, it does nothing. A matching hash means your download was complete and uncorrupted. (there really should be a simpler way to do this, I admit)

Adrien,

In addition to the README.txt file on Sourceforge the sha256 hashes are also in the release announcements at https://www.gnucash.org/news.phtml <https://www.gnucash.org/news.phtml> and https://github.com/gnucash/gnucash/releases <https://github.com/gnucash/gnucash/releases>.
