I installed GPGTools on my iMac, and then tried to decrypt gpg files that I created on my other machine. I am able to decrypt the gpg files on my Linux Mint machine and even on an MS Windows machine. But on the iMac, they won't decrypt. I am trying to decrypt using Terminal: gpg -d filename.gpg It seems to decrypt the files a bit, but terminates before writing the output file. Any advice?
