I tried to save a window arrangement but when I open iTerm it opens two windows:
- one with my saved arrangement
- one with no arrangements
How can I make iTerm2 remember my Window/tabs layout?
First create some profiles and then use Command - Option/Alt - Shift H (H is for horizontal split; or swap in V for vertical split). It will show you a list of your profiles and you can then add those to your split. This short video shows how: iterm2 Profiles and Window Arrangements.
This was answered on superuser by another user and the solution worked for me.
Turn off prefs>general>open default window arrangement, and turn off system prefs>general>close windows when quitting an application.
