I am required to use macos for work but I am having a hell of a time getting my frames to move to the right places in macos, I’ll post snippets from my init.el and hopefully someone can recommend fixes. I use emacs-plus from homebrew and I have a 4k external monitor that is positioned to the left of my laptop monitor. This is the output of (display-monitor-attributes-list)
;; (((geometry 0 0 1440 900)
;; (workarea 0 0 1440 900)
;; (mm-size 286 179)

Problem 1 (solved probably)
helm frame did not pop up in the correct location, I think I’ve figured it out but I’m not sure if it’s the ideal solution

Problem 2 (here be dragons (please help))
Whenever I lock my laptop my main emacs frame ends up on the laptop monitor still sized for the 4k external display I use making it unusable, to ameliorate this I bound the following to C-$ but it doesn’t seem to always work, it seems to maximize on the monitor macos chooses the frame is on instead of on the monitor the frame should be on based on it’s position. When I unplug the monitor and call this function it completely fucks up and moves of-screen and I have to delete the frame and open a new one.
The ideal solution would be not having to use a function at all and instead have macos not fuck up the position of my frames when I lock the pc.
(global-set-key (kbd "C-$")
(defalias 'maximize-frame-on-display
(lambda (&optional arg)
"maximizes frame on a chosen display"
(interactive "P")
(let* ((available-displays (display-monitor-attributes-list))
(display-info (mapcar (lambda (display)
(cons (format "%.1f" (cadr (assq 'workarea display)))
(cadr (assq 'workarea display))))
available-displays))
(sorted-info (sort display-info (lambda (a b) (< (cdr a) (cdr b)))))
(chosen-left (if arg (completing-read "Choose display: " (mapcar #'car sorted-info)) (caar sorted-info)))
(selfr (selected-frame)))
(set-frame-parameter selfr 'left `(+ ,(cdr (assoc chosen-left display-info))))
(set-frame-parameter selfr 'top 0.0)
(set-frame-parameter selfr 'fullscreen nil)
(set-frame-parameter selfr 'fullscreen 'maximized)))))
To make this stranger the following works and always places new frames on the left monitor as it should
(setq default-frame-alist '((ns-appearance . dark)
(ns-transparent-titlebar . t)
(width . 0.5)
(height . 1.0)
(user-position . t)

Problem 3 (kinda solved but I would like something more elegant) macos doesn’t seem to have tiling so I had to make some functions for it, is there a package so I can use that instead?
