~/Library/LaunchAgents/com.dropbox.DropboxMacUpdate.agent.plist so that
2592000 (a month). Interestingly, mine is
3623, instead of
3643 as the author says.
Mysteriously, this file will be overwritten somehow, removing the write access via
chmod -w does not persist either. In the end, I had to resort to
marking the updater non-executable, restore it right before I want to update myself.
cd /Users/albert/Library/Dropbox/DropboxMacUpdate.app/Contents/MacOS; chmod +x *; ./DropboxMacUpdate -check periodic; chmod -x *
