HomeBrew VS Docker-OSX

Don't worry too much about software, you'll find what you need when the need arises. Maybe install Homebrew, it will come in handy later.

Anyhow, I managed to get to the point where I need to run brew, but I don't have that installed. When I go to the linked site https://brew.sh and try to run the command to install it, I just get "Invalid variable name".

I recommend installing homebrew so you can install/update applications from the command line.

Brew & macports have libvirt & virt-manager that are used to manage qemu via GUI.

To install the Homebrew package manager, see: link

In case you're not not aware of it, virtually all devs on mac use homebrew. I slide nearly seamlessly between WSL and mac depending on whether I feel like using my desktop or laptop at the moment. The differences largely boil down to whether I apt install or brew install things. And as much as I'm loathe to admit it, vscode + vim plugin these days gives emacs + evil a pretty good run for the money when it comes to extensible IDEs.

There’s no practical difference between trusting that a popular GitHub account hasn’t been compromised (see: https://brew.sh) and your distro or other package managers haven’t been compromised when it comes to machine setup. If security is that much of a priority you run your own mirrors and don’t pull from public repositories/registries. IME you want to do that for availability anyways if this is for work. Nothing worse than a failed build for a hot-fix because some package registry is temporarily offline.

Others have offered solutions, but for future reference the actual Terminal commands that failed would be useful; "File not found" sounds like a path error, "Command not found" sounds fixable via Homebrew or Macports

TL;DR, about the section that states software from other UNIX-like OSes is hard to port to MacOS, how about homebrew and macports?

First, you’ll want to install some base dependencies for your operating system. We will use brew 27 for this. If you don’t have brew installed you can do so by running:

There is this project https://github.com/sickcodes/Docker-OSX which allows you to run MacOS on docker. In theory this can be an app in Kasm, right?

To my knowledge, there are two ways to get accelerated graphics in a macOS VM: GPU passthrough, and paravirtualized GPU.

GPU passthrough from a Linux host to a Mac VM is already possible. Even with Docker in the sandwich. Then it’s a question of Docker-OSX being furnished for it.

I believe the GPU passthrough foundation is already there:

PR #132: https://github.com/sickcodes/Docker-OSX/pull/132

”[…] this PR introduces GPU passthrough support. This requires extensive configuration on the host”

—

Then there’s “paravirtualized” graphics. I don’t get the name; as far as I know, this is when the guest OS has a virtual graphics device and a driver for it – with acceleration — and the virtual graphics device is actually served and accelerated like any other graphics-accelerated software by a GPU on the host.

As mentioned elsewhere, paravirtualized graphics are available on mac-host-to-mac-guest, and to my knowledge only mac-inside-mac.

(But the “outside” mac can probably be a virtual machine as long as it has a GPU. Even if it’s a passthrough device. Should be technically possible at least and I would guess that it just works.)

Finally, un-accelerated graphics in a macOS VM are surprisingly fast these days. At least on my Linux machine in qemu-kvm, recent versions of kernel / qemu etc. It’s noticeably slower than having properly accelerated graphics but muuuuch faster than I was expecting from macOS VMs I’ve used before.

Finally, headless access to virtualized macOS goes really fast. Working on a mac VM through mosh-shell is excellent.

You can run it in a container: https://hub.docker.com/r/sickcodes/docker-osx

Full credits go to the BlueBubbles docs and sickcodes for Docker-OSX, all I've done is brushed out things to make the process smoother and faster, I hope!

Anyone from Uber here that works on this? You ever expect a DevPod for iOS developers? I've been toying with idea of doing this in work for our devs on Intel MacBooks, using -> https://github.com/sickcodes/Docker-OSX, which enables local running on iOS devices.

I think it's hampered by licensing though, maybe that's why it's not used or mentioned in this post.

I'm not a mac guy, but there is a github repository for docker images of Mac OS here.
