I recently updated to Sequoia 15.3.1 and now tmux isn't displaying the command prompt format I've set on my .bash_profile. I have to manually source .bash_profile every time I open a new session. Anyone know what the problem is? It didn't used to be like this.

I am using tmux on macOS. As the number of repos that I am working with increases, the number of tmux windows increases as well. Just yesterday, I run into the issue that I am not able to open more than 127 tmux windows which breaks my whole workflow. create window failed: fork failed: Too many open files can't find window: 128 can't find window: 128 The workaround that I found does not work sudo sysctl -w kern.tty.ptmx_max=511 What do I need to configure to open more than 127 windows in tmux?

When I try to ls the ~/Downloads folder on my mac I get a ls: Downloads: Operation not permitted error. My user does have rwx permissions on the folder. I can look at the folder just fine in finder. I use tmux in iterm2. The issue does not exist when I use terminal.app. It does work if I start tmux in terminal.app, regardless of which terminal emulator I use to control tmux. iTerm.app already has Downloads folder permissions in Security & Privacy settings. What is the reason for this?

I have a late 2013 MacBook Pro running iTerm2. I don't have tmux installed on it, but I use tmux on the remote Linux host I frequently connect to via ssh. When tmux is displaying a **vertical split** and I use the trackpad to select text, the selection is automatically limited to just one pane. That's exactly how I want it. I have recently begun using a 2018 MacBook Pro. Using the same iTerm2 version (3.2.9), and the same remote tmux session, text selection spans the entire window width instead of staying in a single pane. What setting controls that behavior? I'm aware I can hold Command+Option to select a _block_ of text, but that's not what I'm after. I'm looking to select, for example, a sentence that starts mid-paragraph and spans multiple lines. Block selection doesn't allow that.

I have some AppleScript, to bulk export URLs and titles of tabs from my browser. It used to work, from iTerm (and Terminal, and Script Editor). ***I keep my terminal as long-running sessions in tmux that survives application restarts.*** - It no longer works from iTerm, on a slow timeout, it returns ... got an error: Application isn’t running. (-600). - In Terminal, I'm prompted for "access to control" the app, and then it works. - In Script Editor, it works. **How do I re-prompt for appropriate "application control" access for iTerm?** *It's unclear which setting is needed. I already provide "Full Disk Access" among others. The existing approval may have started failing after an update to the OS, or after the application underwent an update.* Relatedly, can I use some System level tool to see all entitlements by application, instead of by entitlement? It's frustrating to try to guess which additional newly created permissions concepts are required to continue using scripting bridge functionality. --- I've explicitly upgraded the application, still fails. In hopes of resetting the preferences entitlements-application mapping, I could delete iTerm, install it again, and see if that prompts me again.

When running tmux in a terminal window, I can get the usual terminal mouse behavior by holding down the fn key. When using an external keyboard, I do not have a fn key. How can I map this behavior to another key, such as ctrl?

I have searched around and the closes thing I could find to my issue is this: https://stackoverflow.com/questions/23848061/cannot-get-delete-key-to-work-with-tmux-and-osx I am running multiple versions of OSX and macOS and I am using iTerm2. When I go into a tmux session my delete key does not work. I also try to use Ctrl+H and Ctrl+?, which those are not doing anything for me. In iTerm preferences->keys, I have delete sent to ^H. In preferences->profiles->keys, I also have the box checked, Delete key send ^H.

I'm using tmux over iTerm2 in Mac OS 12.5. I have such directives in tmux config file: # resizing panes using Ctrl-Alt-arrows without prefix bind -n C-M-Up resize-pane -U 2 bind -n C-M-Down resize-pane -D 2 bind -n C-M-Left resize-pane -L 10 bind -n C-M-Right resize-pane -R 10 bind -n C-M-k resize-pane -U 2 bind -n C-M-j resize-pane -D 2 bind -n C-M-h resize-pane -L 10 bind -n C-M-l resize-pane -R 10 # switch panes using Alt-arrow without prefix bind -n M-Left select-pane -L bind -n M-Right select-pane -R bind -n M-Up select-pane -U bind -n M-Down select-pane -D C-M-{h,j,k,l} and M-{Left,Right,Up,Down} are working as expected, but for some reason C-M-{Left,Right,Up,Down} are not working at all. But on Windows machine under WSL the same config works fully as expected. Is it some kind of global Mac OS keybinding? But looks like it does nothing. Is there a way to make it work for tmux?

I moved from just using zsh to using zsh inside tmux. As my terminal is iTerm2 for both combinations. I have the following lines in my .zshrc to enable jumping words on a bare zsh command line using the ALT+arrow keys: bindkey 'C' forward-word bindkey '[D' backward-word Sadly this is not working inside my tmux session. > How can I jump words back and forth also in tmux using ALT + arrow > key? What I tried so far: 1. set-window-option -g xterm-keys on [1

When inside a tmux session on the local computer, a command: open "https://www.google.com " opens a url in the default browser. However, when trying to open a file using an app: open -a Preview ./picture.png open produces no error message, but fails to open the file. When I replicate the same command in Terminal app, picture.png opens as expected in Preview app. I have read about a similar problem here: "open" command doesn't work properly inside tmux , however, my problem is different as there is no error output and also, reattach-to-user-namespace is now obsolete. Anyone knows how to troubleshoot this?

When I start a new tmux session (macOS 11.5.1, iTerm2 3.4.10, zsh 5.8, tmux 3.2a) with tmux new, my terminal has no colors, it just displays everything in grey tones. But when creating a new window or split window, the colors are there right from the beginning. Also, when I already started a session and I create another one with tmux new the colors also work from the beginning. When I close every session, and open another one, it displays everything in grey tones again. This is my .tmux.conf, maybe there is something wrong with it?

I recently started using tmux, I rely on visual bells (see Preferences -> Appearance -> Tabs -> Show new-output indicator) in iTerm2 to let me know when processes start/finish. When I start a tmux session in a tab of an iTerm2 window and then change focus, after a minute or two, the 'blue dot' appears in the tab. Nothing has happened in that window. I suspect that this is due to some behind the scenes activity (e.g. keeping the session alive?) Question : 1. How do I keep visual bells in iTerm2 while stopping tmux from issuing these extraneous bells?

I am quite happy with the Terminal changes in El Capitan (see e.g. [this question](https://apple.stackexchange.com/questions/208384/changes-to-terminal-in-el-capitan)) . However, i can't figure out how to enable copying to system clipboard from within Tmux. For instance, now that I am able to select text within Tmux properly by mouse, how can i copy selected text to clipboard as well, in addition to Tmux's own buffer? I have the following in my tmux.conf: setw -g mode-mouse on set -g mouse-select-pane on set -g mouse-resize-pane on set -g mouse-select-window on setw -g mode-keys vi bind-key -t vi-copy 'v' begin-selection bind-key -t vi-copy 'y' copy-selection I tried modifying the last line to bind-key -t vi-copy 'y' copy-selection \; copy-pipe "pbcopy" but it didn't really work. Would be grateful for suggestions! Thanks!

I'm using iterm2 together with tmux and I need the function keys. Ever since I got the TouchBar Macbook Pro and upgraded to HighSierra, the F4 key became disfunctional in iTerm2 and emacs. - The F4 key is used to cycle through the open tabs in tmux forwards - The F3 key (cycle backwards) and in fact all other F keys work as expected - The F4 key worked before the HighSierra / Touchbar upgrade. I used Time Machine to migrate, so no configuration changed. - The F4 also does not work with on an external Magic Keyboard, indicating a software / mapping issue. I suspect that some change in High Sierra makes macOS not pass the F4 key on to applications, but I'm not sure. I have checked that no system wide keyboard shortcut is assigned to F4. What else could I check? Update: The issue can be confirmed with the keyboard viewer , a program that allows to display all keys pressed. It clearly confirms that all keys except F4 are registered by the system while F4 is not.

i spent some time yesterday trying to figure out how i can bind a _double tap_ -esque key binding for tmux, and made some progress, but still incomplete. i am hoping to maximize/minimize a pane within a tmux window by double tapping the shift key. even better if i can granularly map it to the left shift key and have double tapping the right shift key perform a different key binding. while doing some research on how to do this i came across this unix/linux stackexchange q&a . the person who asked that question is essentially asking the same thing i am but on a gnu+linux platform and not a darwin+bsd platform ie. macos. in that _unix/linux q&a_ the op who provides the accepted answer recommends using _xcape_ to map a custom binding for xterm (if i understand correctly), and i believe _xcape_ is tied to X11 window manager, and i'm using Alacritty as my terminal emu along with Aqua as my desktop environment, so i don't believe using _xcape_ is a viable solution on macos. i am aware of karabiner-elements for setting custom key mappings on macos, which i have done for several keys, but i don't think i'd have to set that up (but could be wrong) as this binding is specific to my term emu. it seems either my tmux mappings are not correct or alacritty is not passing the mapping to tmux in order to perform the mapping. this is where things get confusing for me. a couple of things i have tried within my tmux.conf

set-option prefix2 "f11" # WORK!!!
bind-key "f11" resize-pane -Z # double tap f11 (requires holding fn key on mbp keyboard)

when i set the prefix2 with the below setting

set-option prefix2 "C-S-M"
bind C-S-M display "ctrl+shift+meta pressed"

i do **not** see the message flashed within my tmux status bar. i have other key bindings in tmux that use the shift key with arrow keys, so i know it's not a problem with the shift key, so i'm confused as to which program i don't have configured properly. i have my [alacritty.yml][lnk2] config file hosted within my dotfiles repo, and my tmux.conf is hosted within the same repo but i have pasted the important parts above. please excuse my ignorance if i'm forgetting something trivial.

When running iTerm2 / Tmux, I have this cursor: but when I hold the alt/option key, I have this cursor: what is the difference?

I have a couple of executables that I need to call, and within them some OpenCV functions are called, requiring camera access. If I run the executable locally on Terminal from my machine, everything works as expected because I have given Terminal camera access. However if I run the same executable through ssh, or within a tmux window, then the OpenCV function fails as it is not given camera access. It is the same for other command line programs that need camera access, like for example imagesnap. I have noticed that if I run a "screen" or "tmux" session on my machine locally, and then access it remotely over ssh, the camera access works, but if I create the session over ssh, and afterwards access it locally, it does not. Is it possible to give tmux/screen/ssh camera access? There was some talk about this here - https://apple.stackexchange.com/questions/377131/how-can-i-permit-ssh-connection-terminal-programs-to-access-camera - but in the end the proposed solution didn't actually fix the problem, and it was just a workaround that works in specific cases.

I want to set up iTerm2 to pass scroll events to tmux, so I can trivially enter (and exit) scrollback mode for whatever pane is active. Is this possible to do with iTerm2, or automation of some sort, or ...?

I use vim to develop Perl code on a remote Linux box running Debian Jesse. The machine is a virtual machine running in VirtualBox. I use ssh and then issue a vim command to start editing the file. I've been experimenting with tmux on the remote machine to see how I like it. But I cannot for the life of me figure out how to copy and paste text between vim instances in two different tmux panes. I'd prefer to be able to use both the mouse and vim-like keystrokes (yy, dd p) to do this. I've tried just about every recommendation out there for trying to get this to work but I haven't gotten anywhere. I'm running El Capitan. Is there a definitive answer out there for getting this to work?
