Image by via FlickrBefore I start this article, let me say that I'm not a big "make your Ubuntu desktop look like a Mac" kind of guy. I don't use a dock. I don't have an Apple icon on my top panel. I pretty much use straight Gnome. I even like the spatial view someitmes.
There are plenty of people who want the Apple desktop experience, though, and I'm going to tell you how to get it. No, I don't mean pixel-perfect themes. I mean the stuff that counts. Usability. There are three main elements to Apple's usability on the basic desktop: a dock, menus on the top panel, and a launcher. Lucky for us, Ubuntu 9.04 Jaunty makes all these pretty easy.
Let's start with the launcher, which in OS X is called Quicksilver. In Ubuntu, we have a worthy competitor in GNOME Do. It's already in the repositories and at version 0.8.1.3. Installing just means clicking this link. When you are finished, Press ALT-F2 and type "gnome-do" or launch it from Applications > Accessories.
When the two-panel (and rather ugly) application appears, click on the arrow in the upper-right corner to open the Preferences box. In the General tab, you'll want to set Gnome Do to start automatically and to hide on launch. Next, you need to enable some of the many plug-ins available for Do. Changing "Show: Official Plugins" to "Show:All Plugins" will give you many more choices. I suggest you enable the Tracker search, Google Apps, , micro-blogging (Twitter and Identi.ca), IM, browser, note, and music player plugins as a start. Some of these will require some configuration with user names and passwords.
Gnome Do appears with a press of the super or Windows key and the spacebar simultaneously. Instructions for using it are on the .
Avant Window Navigator for this because it's quite a looker, but I'm going to recommend that you use the built-in dock in Gnome Do. You will need a compositing window manager in order to enable the dock. If you have Visual Effects enabled in Preferences > Appearance, then you are OK.
If you can't enable effects, you aren't out of luck yet. Metacity (Gnome's default window manager) can do compositing, though it's turned off by default. Hit Super-space to start Gnome Do and type "gconf-editor" and ENTER to launch the GConf editor. Under Apps > Metacity > General, put a check next to Compositing Manager and close the application.
To enable the dock, access the preferences in Gnome Do and change the theme to "Docky" in the Appearance tab. Bam! You're finished with the dock.
Another important aspect of OS X usability is the top menu, which conforms to Fisk's Law about where it should be placed. Personally, I have trouble getting used to it, but there's no doubt it's easier to hit than a menu on the window. Getting a top menu for GTK+ used to be the hardest part of this process, requiring patching and compiling, then later it was easier but required downloading and installing using force overwrite. These days, Gnome2-GlobalMenu has its own repository and is easy to set up. Add the following repository to Software Sources or manually in /etc/apt/sources.list
gnome-globalmenu. Remove the menu and quick launchers on your top panel, right click and add the global menu and a normal ubuntu menu if you like.
Choose a theme like Dust Sand, and you're done. There's no real reason to move the traffic lights to the left, but you can if you want to by using the GConf editor and changing the "button Layout" under Apps > Metacity > General.
