Here is the Terminal command (in MacOS or Linux command line interface) to view the most recent ten and all subsequent lines written to the Veil debug log.

tail -f ~/.veil/debug.log

In MacOS your wallet data folder is by default in a different folder, so please try:

tail -f ~/Library/Application\ Support/Veil/debug.log


You can exit the display of debug log text by using Ctrl+C on the keyboard.

If you are using the GUI (graphical user interface) wallet (veil-qt) then there is a button to launch your default text editor with the debug.log file. The only reason I don't recommend using this button in Windows is because for most people the default Windows text editor is Notepad.exe, which is not at all good at opening (potentially) huge text files. 



To reveal this button (to open the debug log file) simply click on the gears (settings) icon in the right hand side tab bar and then click on "Advanced options" revealing the "Information" tab of the Debug Window.


Please note: The above screenshot is from a TESTNET wallet. That is not a real 2.3 million Veil.
