[BUG] kitty-icat not showing image in Tmux on mac

• I have checked the FAQ but the issue is not covered

Description

This was working wonderfully in TMUX, on my M1 mac mini, I switched to an M4 and it does not work.

I raised this here:
#1039 (comment)

User @JoshSald confirms has the same issue, also another M4 in my discord confirmed that has the same issue only with M4

I haven't confirmed with M2 and M3 users, so I assume the issue is only with M4 macs

My config can be found here
https://github.com/linkarzu/dotfiles-latest/blob/main/fastfetch/config.jsonc

I'm using kitty-icat when inside tmux

Here I'm outside tmux just using kitty and it works

Logo (kitty-icat): running kitten icat failed posix_spawnp() failed

This is an interesting error message. Please try if kitten icat --align=left ~/.config/fastfetch/images/link-green.png works for you.

I don't use kitty as my main terminal, I use Ghostty and can't run that there. If I run it in kitty though it works, but I don't use tmux there at all.

Am I able to run it in Ghostty?

[CarterLi]

Fastfetch run kitten icat internally if you use kitty-icat. So if kitten icat doesn't work in your terminal (in your case, tmux in Ghostty), kitty-icat won't work in fastfetch.

• Ok, I figured this out. I had kitty installed and it was working, but for a strange reason it was not in my path, not sure if brew messed up or something.
• So I uninstalled kitty, re-installed it through brew on macOS, and now fastfetch works in ghostty
• So I guess ghostty then must use the kitten somehow, not sure
• So I'm closing this, appreciate it!
• If you have the same issue, make sure you have kitty installed, even if using Ghostty as your main terminal

Please leave a post in the discussion to avoid potential misleading, since the issue have no business with M4 at all.

[rhodes-b]

To give some more clarity (the person asked in the ghostty discord)

Ghostty does support the unicode placeholders part of the kitty image protocol which allows KIP to work in programs like tmux
https://sw.kovidgoyal.net/kitty/graphics-protocol/#unicode-placeholders

To what CarterLi was saying, if you choose kitten icat as the image method it 100% requires that you have kitten
if you just use kitty for the image method you do not need kitten installed.
I'm not sure the kitty image method supports the unicode placeholder though (i've never checked)
kitten obviously supports its since its made to test kitty

[CarterLi]

Fastfetch uses kitten simplily because it's more lightweight and doesn't require a full kitty install.

[linkarzu]

You can get kitten separately if you just use ghostty. Discussion in Ghostty discord
