May 13, 2020 Download the latest version of Dark Boot for Mac - Enable the black boot screen with white Apple logo on all Macs. Read 5 user reviews of Dark Boot on MacUpdate. Dark Mode is a dramatic new look that's easy on your eyes and helps you focus on your work. Dark Mode uses a dark color scheme that works system wide, including with the apps that come with your Mac. And third-party apps can adopt it, too. Go into system preferences, open up ‘Keyboard’ You should see this window. Click the ‘Keyboard Shortcuts’ tab at the top, then ‘Services’ in the left pane. Scroll down in the right pane to the subsection labeled ‘Text’, and to the OpenPGP options. Here is how to turn on OS X dark theme with this way. First of all, go to 'System Preferences' and click on 'Displays' option. From the three tabs given on the next screen, choose 'Night Shift'. Now, from the 'Schedule' option, either choose 'Sunrise to Sunset' or 'Custom'. Aug 20, 2018 Here’s what you need to do to use white email background with Mojave’s Dark Mode. 1) Click System Preferences from the Apple menu or the Dock. 2) Click the icon labeled General. 3) Click Dark next to Appearance. Doing so shall turn on the system-wide Dark Mode on your Mac. 4) With Dark Mode on, fire up Apple’s Mail app on your Mac.

The Mojave update

Mac is a popular OS that keeps coming up with new updates to improve the user experience. Mojave is the newest update.

The latest benefits of the Mac OS

You will get some handy benefits free of charge. Besides the obvious advantages, there are covert improvements that will boost your Mac.

If you’re a user of Mac OS, upgrading to the Mojave version is the logical next step. The only thing you should worry about is to update your apps, as the old versions won’t work on Mojave.

The most significant changes in the newest version relate to aesthetics. With Mojave, you can mute the colors of the interface, so you don’t find yourself blinded when working at night thanks to the Dark Mode. Furthermore, the Dynamic Desktop feature changes the image on your desktop to match the time of the day.

As an operating system, Mac OS has always tried to make things sleek and minimalist on your desktop. However, in the older versions, the sync between Mac and iPhone led to a lot of clutter. To counter that, Apple added Desktop Stacks to make your desktop organized according to the criteria you desire.

These, and many more features allow Mac users to enjoy an even sleeker operating system. Another thing that draws attention is an improvement in Continuity - the connection between the phone and the computer. In general, the newest version of the operating system brings everything the users loved in the previous versions - only enhanced.

Is there a better alternative?

No. Unless you rely too heavily on old apps without new updates, Mojave is a logical extension of your current user experience.

Where can you run this program?

Mac Mojave runs on Mac computers featuring an OS X 10.8 and later versions.

Our take

This new update took the best features and improved them. There are no obvious drawbacks, Mojave does its job, and it does it properly.

Should you download it?

Yes. If you're a Mac lover, you'll probably want to get OS X Mojave.

Subgraph OS: Adversary resistant computing platform

Subgraph OS is a desktop computing and communications platform that is designed to be resistant to network-borneexploit and malware attacks. It is also meant to be familiar and easy to use. Even in alpha, Subgraph OS looks and feels like a modern desktop operating system.

Subgraph OS includes strong system-wide attack mitigations that protect all applications as well as the core operating system, and key applications are run in sandbox environments to reduce the impact of any attacks against applications that are successful.

Subgraph OS was designed to reduce the risks in endpoint systems so that individuals and organizations around the world can communicate, share, and collaborate without fear of surveillance or interference by sophisticated adversaries through network borne attacks. Subgraph OS is designed to be difficult to attack. This is accomplished through system hardening and proactive, ongoing research on defensible system design.

Hardened kernel built with grsecurity, PaX, and RAP

Subgraph OS includes a kernel hardened with the well-respected grsecurity/PaX patchset for system-wide exploit and privilege escalation mitigation. In addition to making the kernel more resistant to attacks, grsecurity and PaX security features offer strong security protection to all processes running without modification (i.e. recompiling / relinking).

The Subgraph OS kernel is also built with the recently released RAP (demo from the test patch) security enhancements designed to prevent code-reuse (i.e. ROP) attacks in the kernel. This is an important mitigation against contemporary exploitaion techniques and greatly increases the resistance of the kernel to modern exploits that can be used to escalate privileges once an application on the endpoint is breached. grsecurity, PaX, and RAP are essential defenses implemented in Subgraph OS.

The Subgraph OS kernel (4.9) is also built with fewer features to the extent possible producing a widely-usable desktop operating system. This is done to proactively reduce kernel attack surface.

Sandboxed applications

Subgraph OS runs exposed or vulnerable applications in sandbox environments. This sandbox framework, known as Oz, unique to Subgraph OS, is designed to isolate applications from each other and the rest of the system. Access to system resources are only granted to applications that need them. For example, the PDF viewer and the image viewer do not have access to any network interface in the sandbox they're configured to run in.

The technologies underlying Oz include Linux namespaces, restricted filesystem environments, desktop isolation, and seccomp bpf to reduce kernel attack surface through system call whitelists. Subgraph is regularly instrumenting applications and libraries to limit the exposed kernel API to what is necessary for each sandboxed application to function. Many applications only need about one-third to one-half of the available system calls to function, and the Subgraph Oz sandbox framework ensures that the unnecessary system calls cannot be invoked (Oz can and often does restrict system calls to specific known parameters to further narrow kernel attack surface through system calls such as ioctl(2)). Subgraph OS will soon be using gosecco, a new library for seccomp-bpf that lets policies be expressed in a format that is more efficient, cross-platform, and understandable to humans.

Sandboxed applications include:

Web browser
Email client with built-in support for encryption
CoyIM instant messenger
LibreOffice productivity suite
PDF viewer
Image viewer
Video player
Hexchat

Memory Safety

Most custom code written for Subgraph OS is written in Golang, which is a memory safe language. Golang libraries are also often implemented in pure Golang, which is in contrast to other popular languages such as Python. While the Python runtime may be memory safe, the C languages wrapped by so many of the commonly used libraries expose tools written in Python to the same old memory corruption vulnerabilities.

Application firewall

Subgraph also includes an application firewall that will detect and alert the user to unexpected outbound connections by applications. The Subgraph application firewall is fairly unique to Linux-based operating systems and is an area of ongoing development.

Other security features

Subgraph OS is constantly improving and hardening the default security state of the operating system. This includes making configuration enhancements and adding entirely new mitigations.

Additional security features in Subgraph OS include:

AppArmor profiles covering many system utilities and applications
Security event monitor and desktop notifications (coming soon)
Roflcoptor tor control port filter service
Port to new seccomp-bpf golang library Gosecco

Hardened

Subgraph OS is based on a foundation designed to be resistant to attacks against operating systems and the applications they run.

Anonymized

Subgraph OS includes built-in Tor integration, and a default policy that sensitive applications only communicate over the Tor network.

Secure communication

Subgraph OS ships with a new, more secure IM client, and an e-mail client configured by default for PGP and Tor support.
