i’ve used Chezmoi for years now pretty successfully. works on my Mac and Linux machines. it probably could be made to work on Windows. i am transitioning to NixOS, but i’ll probably keep using it anyway, since i still have Macs for work (and because they’re great laptops don’t @ me). the only real downside is that it only works for the home folder, so i have to manually control stuff for /etc, but i generally prefer user configuration for most tools anyway.
i had messed around with Ansible for this in the past, but i didn’t really like it for this use case. it’s been a while tho so it’s hard to say why.
not to pile on, but you might also look at GNU Stow. i decided against it, but it’s there.
I’m not a Mac fan, but I do keep a Hackintosh VM with GPU passthrough to run the occasional XCode and the like or send a text message when I’m too lazy to pull out my iPhone.
I will say that MacOS’s standardized interface is rather nice, though.
On one hand, I did go through heck at one point trying to get the config.plist right to no avail. I then found some guy’s preconfigured OpenCore image made specifically for virtual machines (I usually avoid such things, but as a VM is basically a standardized platform, I’ll take it), upon which my life has been very easy ever since. Passthrough was just a matter of copying my Windows passthrough scripts.
One day, I want to buy a Google Pixel and run LineageOS, but I’m not in the position to do that right now.
I'm writing from [GrapheneOS] (https://grapheneos.org/) right now. I recommend it more over LineageOS as it seemed more polished and profiled. I have OnePlus 7 Pro with LineageOS MicroG though.
For the GPU passthrough, I reused what I did for Windows 10.
After that, I think you have to add a few QEMU flags in the Virt Manager XML (have to find them), but after that, you just download an OpenCore ISO from https://github.com/thenickdude/KVM-Opencore and it pretty much just works (except for audio, which is something I’m working ob. I got a Pulse server running on MacOS once and forwarded it to my Linux sound server over the virtual network, but I haven’t been able to replicate that.) Every few months, they’ll update it with the latest OpenCore.
