IORegistryClone VS yabai

First of all make sure you have a backup of your current EFI then try some patching. Then grab a copy of IOReg and open it. Search for iGPU entry and locate entry (eg. AppleIntelFramebuffer@0 in my case) with a child “display0” it controls the physical display. Select that entry (eg. AppleIntelFramebuffer@0) and on the right panel locate connector type. Then check if it’s set to “00 08 00 00” or not. (This is the connector type for HDMI). If not then. Leave it as it is (in case of laptops it is mostly 02000000). Then open your config.plist in propertree and head to DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0). Then add these entries here (Don’t touch anything already present there just add these) “framebuffer-patch-enable = 01000000”, “framebuffer-conX-enable = 01000000” and “framebuffer-conX-type = 00080000” [IMPORTANT: make sure X in conX is the number you’ll find in the ending of AppleIntelFramebuffer@ which you located previously and make sure it has a child “display0” this is important (in my case=0)] and save the config.plist and reboot. Your HDMI port should be working now. Not 100% sure about it but it works most of the time.

IORegistryClone - Utility to browse IO registry with a GUI interface, it can be useful for patching features such as CPU power management, USB mapping, etc

Do you have IORegistryExplorer ?

It exists! Check out [yabai](https://github.com/koekeishiya/yabai), which is nicely paired with [skhd](https://github.com/koekeishiya/skhd).

I have a 49 inch CRG9 and the best recommendation for window management is Yabai (https://github.com/koekeishiya/yabai) along with skhd (https://github.com/koekeishiya/skhd). Yabai is a greedy window management solution that tries to fit opened applications in given space and skhd let's you easily jump between those using keyboard shortcuts. This has massively improved my ultrawide experience.

Only disclaimer is, configuring yabai has a slight learning curve.

Want something free that's better than tiling on Windows? Yabai.

Here it is. There is no visualization of the stack, which apparently Stackline in the other comment supports, but I don't tend to need that. Just being able to move between the windows is good enough for me.

I use Yabai on my Macs without SIP enabled. Here’s a list of the features that absolutely require SIP to be disabled: https://github.com/koekeishiya/yabai/issues/1863

But you don’t need to disable SIP just for tiling.

> there's still a ton of tinkering and tweaking you need to do to get Yabai really working correctly

This is pretty much true of basically every tiling window manager on Linux, too.

For me, using Nix-Darwin for MacOS and NixOS has drastically simplified my tiling window manager setup after initially doing the work to figure out my ideal config.

SIP is a feature that protects you from malicious actors with root (admin) access on your device. After they've encrypted your photos and drives and changed your passwords, it prevents them from making your machine unbootable by deleting or altering system binaries. As a side effect of this protection, you give up certain freedoms to customize your system.

For instance requires SIP to be disabled.

This is disproven by the fact that Yabai [1] can instantly swap spaces with SIP disabled.

If you find the native window management lackluster (like I do), you can install a window manager like Amethyst, or yabai, veeer, or many others.
