(Q) How do I expand the Putty window it is very small by default?
(A) Unfortunately at this time, Putty for Mac does not support resizing an established connection.
What you can do is create another session for your application and set a custom Window size for it by changing the Columns and Rows and then save that for future usage of that application.
I know it is not optimal and hopefully we will be able to support resizing sometime in the future.

(Q) I downloaded and installed Putty but I get a security warning when trying to run it, what’s up?
(A) If you try to open an app that is not registered with Apple by an identified developer you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began.
To override your security settings and open the app anyway:
- In the Finder, locate the app you want to open.
Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
- Press the Control key and click the app icon, then choose Open from the shortcut menu.
- Click Open.
The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
Note: Another way to grant an exception for a blocked app is to click the “Open Anyway” button on the Security pane of System Preferences. This button is available for about an hour after you try to open the app. To open this pane, choose Apple menu > System Preferences, then click Security & Privacy.
Follow the above instructions and Putty should run as expected.
(Q)Where can I purchase Putty for Mac and how much does it cost?
(A) Putty for Mac cost just $15.00 and can be purchased here.
