Ubuntu is a capable desktop operating system, but its default appearance is fairly minimal. With a few community-maintained themes and GNOME extensions, you can give it a polished, macOS-inspired look. This is the result we are working toward:

Install the GTK theme
First, install GNOME Tweaks and Extension Manager:
sudo apt install gnome-tweaks gnome-shell-extension-manager
Next, clone the WhiteSur GTK theme repository. Open the cloned directory and run its installation script:
./install.sh
Install a matching icon theme
For Ubuntu 22.04, download the macOS icon pack from GNOME-Look. Create a .icons directory in your home folder, then move the extracted icon-theme folder into it. Press Ctrl+H in the file manager to show hidden files and directories.
On Ubuntu 24.04, you can instead install the icons from the WhiteSur icon theme repository.
![]()
![]()
Configure GNOME extensions
Open Extension Manager and install the Blur my Shell and User Themes extensions:




Then open GNOME Tweaks from the application menu and apply the theme and icon settings:


From here, adjust the settings to suit your preferences. You may also find these extensions useful:
Apps Menuadds an application menu to the top bar.Dash to Dockprovides a highly customizable, macOS-style dock.Freondisplays system information such as CPU temperature and fan speed in the top bar.Logo Menuadds a configurable logo menu to the top bar.

Add wallpapers and fonts
For a static background, browse the macOS wallpaper archive from 512 Pixels. For a changing background, follow the setup instructions in the Linux Dynamic Wallpapers repository.
As a final touch, you can use Apple’s SF Pro Display font. This community guide explains how to install and configure it on Linux.
