I have an ancient Mac that I'm looking at wiping when Lion support goes the way of the dinosaur. I still like the idea of keeping it as Mac-like as possible.

Are there any Linux distros that mimic to a very large degree OS X functionality? Interface bears more importance than under the hood development.

    Since its a mac, what processor? If its a PPC model, your needs are going to be VERY different. You can also, reasonably simply hack together a mac-like theme off a basic cli only install. Feb 10, 2014 at 7:25
  • I think that the real question is "which DE/WM is similar to OS X's".

EDIT: Clementine OS is now long dead. Please disregard this answer, and use eOS or something instead.

Clementine OS aims to be as similar as possible to Mac OSX -- it boasts many of the same features, such as expose, and is visually almost the same. It comes from a now discontinued (sold) project called Pear Linux and has an interface virtually identical to that of Apple. Here is a screenshot:

Clementine OS UI

If you just want an Apple-like interface, I think I will go so far as to say that Clementine OS is perfect -- Oops! I just did --, although you may not like the Mavericks-style.

Under the hood, it is based on Ubuntu, so it is nice and stable and has a lot of available packages.

    Clementine OS is no longer available. The German website heise.de posted this headline today: heise.de Feb 7, 2014 at 12:34
  • You can still use the themes and programs on Ubuntu, though. I expect.

  • Screen-shoots present Pear OS Linux which is also unavailable nowadays.

    It seems that Clementine Linux is no longer active and the download link is broken (I was unable to find an updated link)

Elementary Luna OS aims to be as "Mac-like" as possible. It's built for usability and to visually look like Mac OS X.

Etoile is a Linux distro aimed at using the GNUStep project to do system tasks, thus allowing a vaguely similar programming environment to Cocoa. While more similar to NextStep in terms of visual style, it will have some familiarity from a programming perspective.

  • I don't understand why people says that elementary is looking like mac. What is common in between mac and elementary? Is a dock all about being like Mac OS X?

When I first got my MacBook Pro at the end of last year, I thought its UI was very similar to Unity (the default desktop environment in Ubuntu). Now, Unity is not 100% like Mac, but I think it's very close in many ways, especially when compared with most other distros. The top menu bar, the dock, the Settings app, etc. Here's a screenshot:

(I took the screenshot on my Retina display MacBook Pro, and unfortunately, Unity currently doesn't support HiDPI displays yet, so things look a little out of proportion. But I'm hoping that come 14.04 LTS release time, this will have ironed itself out.)

Here's another screenshot, showing the top menu:

Showing the top menu

The top menu style is quite reminiscent of the Mac UI, but with two differences:

  1. There is no Apple menu.
  2. The Alt-Tab task switcher is still window-centric (though windows are grouped by their owning application), not application-centric. This probably won't make a huge difference to you unless you're wedded to the "every application is basically MDI" aspect of the Mac UI.

Update: My boss tells me that Ubuntu 14.04 now does support HiDPI displays! Here's a screenshot of Unity (with Firefox 29 beta, that also supports HiDPI) running on his MacBook Pro 15 with Retina:

Yay, Ubuntu 14.04 has HiDPI support!

(I'll get around to updating the other screenshots soon.)
