theos VS Lenovo-ThinkPad-T450-macOS-Catalina

I am pretty sure everything you need is findable on https://theos.dev

i had been using “rootless=1” as per https://github.com/theos/theos/issues/685

The next step is to actually start making tweaks. Install a tool called Theos for your appropriate device. The installation wiki can be found here: https://github.com/theos/theos/wiki, please make sure to follow the appropriate platform instructions. After that, you are ready to start making tweaks, please follow a tweak development guide. (Here's one if you're lazy: https://icrazeios.com/kodey-tweak-guide/)

I followed this fix and that seemed to solve the permissions issue, but now I’m getting this.. lol

You can use Theos to build macOS, tvOS and iOS applications on Windows (through WSL). You won't have every Xcode functionality available to you, the most important one being the interface builder. However, it works quite well in my opinion and I have built a few applications with it.

You need to compile it with theos, if you don't want to do it yourself I can compile it for you later

This is why it's important to get apps from outside of the Apple App Store. Most free software app developers don't seem to distribute ipa files directly or publish via apt, instead opting to only publish source code as free software and then also publish on the Apple App Store. I tried but could never figure out how to compile an ipa file on iOS (Hopefully once this issue is resolve it will be easier.), and I don't have a Mac.

“A cross-platform build system for creating iOS, macOS, Linux, and Windows programs.” - Theos.dev. I’m not sure I’d say it replaces Xcode, because the two serve different purposes, but you don’t need Xcode for tweak development. The difference between the two is that theos is catered specifically for tweak development whereas Xcode is not. That and Xcode is platform specific, as you mentioned.

I know about that https://github.com/racka98/Lenovo-Thinkpad-T450-T450s-Hackintosh-Guide-Opencore and that https://github.com/jsassu20/Lenovo-ThinkPad-T450-macOS-Catalina at least. Will try soon.
