macOS 26 (Tahoe) Scripting Addition support

[Melonchanism]

Currently, yabai-sa does not work on macOS 26. This doesn't really matter for now because there's still months left, but I felt that it needed an issue for tracking at least.

What to you mean by "does not work on macOS 26"? everything?
Because currently the one issue i'm facing is space focus, it's not trigger error, just not work. Everything else i use everyday still work, BSP layout, fullscreen, window swap, send window to another space, ....

Yeah, it works mostly, but script additions cannot change current space.

Ok I edited it to be more specific, mb.

I was able to retrieve the dock spaces pointer using the following pattern:

?? ?? ?? ?? ?? ?? ?? 91 ?? ?? ?? F9 ?? ?? ?? B4 ?? ?? ?? 94 F5 03 00 AA E0 03 17 AA

With an offset of 0x200000.

Notes:
• fix_animation: pointer still works.
• set_front_window, add_space has also been found (though it remains untested).
• The functions dppm, remove_space, and move_space couldn't be found in new binary.

My workflow heavily relies on the focus space command — this is now fixed using the pattern mentioned above.

When loading sa，it's just not working now.

Yep, tried full Mac OS reset just in case, same... disabled csrutils from recovery, and tried setting the boot arg + reboot

ashu@192 ~ % sudo yabai --load-sa
Password:
yabai: missing required nvram boot-arg '-arm64e_preview_abi'!
ashu@192 ~ % sudo nvram boot-arg=-arm64e_preview_abi
ashu@192 ~ % sudo yabai --load-sa

I won't be looking at macOS 26 support for at least a couple of months (Public Beta ~4). Not interested in running a prototype, and don't have the storage to dedicate for a VM version.

[ashupednekar]

Agreed, moved back to sequoia... only reason I had updated was to try out the apple containers thing

Thanks for this start - making my own local edits to support the prototype as it is.

Can you share the basic workflow for tracking down patterns and offsets for these functions?
If you have a list of tools; e.g. IDA/Ghidra, find specific symbols, find a byte pattern that doesn't move much (in a struct?), then record the fixed offset to the pointer?

Has anyone found a temp solution to get it working?

I just rolled back to "good-old" Sequoia.

Temporary solutions won't exist for this kind of app (unless something changes between the betas, then it's not a good temporary solution)
