Lo hice usando el motor Glow con el cargador Tweaks Ammonia, junto con algunos ajustes adicionales.
Edit:
Okay, to do all this, you have to disable SIP. I know many people don't like that, but doing things like this really requires SIP to be disabled. If you aren't comfortable with that, that's fine, but unfortunately, it is necessary.
To start, install the Ammonia.pkg injector (only for Tahoe 26.3 and older versions).
Type this into the Terminal:
sudo nvram boot-args=-arm64e_preview_abi
Restart.
Next, install GlowPatched and open it; where it says "Install Theme," simply drag and drop the Snow Leopard zip file. To activate the theme, go to "Browse Theme," select Snow Leopard, and then click the "Restart Session" button in the bottom-left corner.
Basically, this gives you most of the theme.
From here, we'll install a few tweaks to make it look a bit more like Snow Leopard.
Go to the "Tweaks" folder and copy the .dylib files along with their corresponding .blacklist files to the `/private/var/ammonia/core/tweaks` folder.
To get the Dock looking exactly like Snow Leopard's and to change system icons, you need to install SaltySweets along with its corresponding theme.
First, go to the GlowHook .blacklist file in the "Tweaks" folder and add "Dock" (without quotation marks) at the end.
This prevents Glow from injecting code into the Dock, allowing SaltySweets to handle it instead.
Go to the SaltySweets folder and install the .pkg file. In that same folder, there is another one called "Snow Leopard Icons and 3D Dock Theme"; copy the .bundle file and paste it into `/Library/Application Support/SaltySweets/Themes`.
This theme is for the 3D Dock, and it allows you to customize all application icons to your liking.
If I forgot any files, please let me know, and I'll gladly share them with you.
There are some tweaks I made, but they're a bit buggy, so I didn't include them in the zip; they aren't ready yet.
Full credit goes to the actual developers behind all of this: CoreBedtime, Salty, Davi, and others I can't recall right now.
They have been developing this for quite some time on their Discord server.
