Vim can't scroll in iTerm2

Question

My vim can't scroll in iTerm2 even set mouse=a has added in .vimrc file.

Within tmux, however, vim's scroll function works correctly.

What's wrong with my vim?

how do you scroll? mouse? arrow keys? or `hjkl`? or `ctrl+?`? — Jason Hu, Aug 19 '15 at 19:04
Please run `vim --version` from the command-line, or in Vim, enter :version and provide output. — Valery Viktorovsky, Aug 19 '15 at 19:21
On a side note, using the mouse to scroll is an antipattern in both Vim and tmux, and nullifies the advantages of using such tools. — zool, Aug 22 '15 at 09:28

Recent versions of vim support the "SGR" protocol, you can add code bellow to your .vimrc:

set mouse=a
if has("mouse_sgr")
    set ttymouse=sgr
else
    set ttymouse=xterm2
end

I had the same issue, and Valery's answer did not work for me. What did work is checking the "Enable mouse reporting" box under Profiles > Terminal in the iTerm preferences.

It is likely that you can accidentally disable this which does break scrolling in Vim – aubreypwd Oct 26 '22 at 17:29
