Dark Mode

The option for Dark mode is in the System Preferences app, which you can open from the Dock, your Applications folder, or by clicking the Apple icon at the top of your screen and selecting “System Preferences.” When you’re there, click on “General.” At the top of the window, you’ll see the toggle between light mode and dark mode. Oct 12, 2018 The Dark Mode theme available in modern macOS versions offers a unique visual interface and desktop environment to work in, shifting nearly all onscreen visual elements to dark grays and blacks. For many Mac users, the Dark theme is perhaps the most popular new feature to arrive in MacOS Mojave, Catalina, and Big Sur, and the new user interface. Jun 08, 2015 The Piker-Alpha bootloader can be used to boot OS X 10.11 El Capitan on unsupported Mac Pro models: This approach, using a fork of tiamo’s bootloader, uses a replacement native EFI32 boot.efi boot loader that thunks EFI64 calls from the 64-bit OS X kernel to the EFI32 firmware. Dark Mode, in general, is a system-wide teme followed by most of the mobile and computing Operating Systems to switch the color major color schemes into a dark shade. Whether it be Windows, Mac, Android or iOS, the basic theme for the system UIs and third-party apps are set to white or light-themed shades.

In macOS 10.14 and later, users can choose to adopt a dark system-wide appearance instead of a light appearance. In Dark Mode, the system adopts a darker color palette for all windows, views, menus, and controls. The system also uses more vibrancy to make foreground content stand out against the darker backgrounds.

Focus on your content. Dark Mode puts the focus on the content areas of your interface, allowing that content to stand out while the surrounding chrome recedes into the background.

Dark Mode is an aesthetic choice for users. Users can choose Dark Mode as their default interface style, and may use it at any time of day or in any lighting conditions.

Test your design in both light and dark appearances. See how your interface looks in both appearances, and adjust your designs as needed to accommodate each one. In Dark Mode, see how your designs look when Desktop Tinting is active. Decisions that work well in one appearance might not work in the other.

Adopt vibrancy in your interfaces. Vibrancy improves the contrast between foreground and background colors, making your foreground content appear more prominent. See Translucency and Vibrancy.

Colors

The color palette in Dark Mode includes darker background colors and lighter foreground colors. These colors aren’t necessarily an inversion of their light counterparts. While many colors are inverted, some are not. For example, both light and dark appearances use dark lines to create visual separations between views.

Embrace colors that adapt to the current appearance. Semantic colors (like labelColor and controlColor) adapt to the current appearance automatically. When you need a custom color, add a Color Set asset to your app’s asset catalog and specify the light and dark variants of the color. Avoid using hard-coded color values or colors that don’t adapt.

Ensure sufficient color contrast in all appearances. Using system-defined colors ensures a proper contrast ratio between your foreground and background content. For custom foreground and background colors, strive for a contrast ratio of 7:1. This ratio ensures that your foreground content stands out from the background, including when Desktop Tinting is active. It also ensures that your content meets more stringent accessibility guidelines. At a minimum, make sure the contrast ratio between colors is no lower than 4.5:1.

Soften the color of white backgrounds. If you must use a white background for your content in Dark Mode, choose a slightly darker white that prevents the background from glowing against the surrounding dark content.

For related guidance, including information about color accessibility standards, see Color and Contrast.

Desktop Tinting

Apps running in Dark Mode benefit from Desktop Tinting. When active, Desktop Tinting causes window backgrounds to pick up color from the user's desktop picture. The result is a subtle tinting effect that helps windows blend more harmoniously with their surrounding content. Users who prefer not to have the additional tinting, perhaps because they work with color-sensitive content, can disable this effect by choosing the graphite accent color in System Preferences.

Include some transparency in custom control colors. Transparency lets your controls pick up color imparted by the window background and by Desktop Tinting. That additional color creates a harmony between your controls and backgrounds, which persists even when the desktop picture changes.

Images, Icons, and Glyphs

The system makes extensive use of template images in Dark Mode. A template image is a monochromatic image with transparency, anti-aliasing, and no drop shadow that uses a mask to define its shape. The system also includes many full-color images that are optimized for both light and dark appearances.

Use template images wherever possible. Template images adapt to light and dark interfaces, and they can take full advantage of vibrancy. Full-color images that look good in one interface might look washed out in another. For related guidance, see Custom Icons.

Design individual glyphs for light and dark appearances when necessary. A glyph that uses a hollow outline in light mode might look better as a solid, filled shape in Dark Mode.

Make sure full-color images look good. Use the same asset if it looks good in both light and dark appearances. If an asset looks good in only one appearance, modify the asset or create separate light and dark assets. Use asset catalogs to combine your assets into a single, named image.

Typography

The system uses vibrancy and increased contrast to maintain the legibility of text on darker backgrounds.

Use the system-provided label colors for text. The primary, secondary, tertiary, and quaternary label colors adapt automatically to light and dark appearances. For related guidance, see Typography.

Use system views to draw static text. System views and controls make your app’s text look good on all backgrounds, adjusting automatically for the presence or absence of vibrancy. Don’t draw text yourself when you could use a system-provided view to display that text instead. See NSTextField and NSTextView.

Part 0 – Introduction

Here’s my basic guide for PGP on OS X. The OS in question is OS X 10.9 Mavericks, but it should still work for other versions. As for the tool itself, we’ll be using GPG Suite Beta 5. This is my first time using OS X in… years. If you see anything I’m doing wrong, or could be done easier, feel free to correct me in the comments.

If you’ve done your research, you’ll see it’s not recommended to do anything darknet related on OS X, but I’m not going to go over the details here. You’ve obviously made your decision.

Part 1 – Installing the software

Like I said above, we’ll be using GPG Suite Beta 5. If you’re curious and want to see the source code, you can do so here.

1. Head on over to https://gpgtools.org, and download ‘GPG Suite Beta 5′
2. Open the file you downloaded, you should see this screen. Double click on ‘Install’
3. Follow the installation process. If successful, you should see this screen. You can now close the window

Part 2 – Creating your keypair

GPG Suite actually makes this a super simple process. Just like the Linux guide, we’ll be using 4096 bit length for encryption.

1. Open up GPG Keychain, you should be greeted by this beautiful window
2. Click ‘New’ at the top left of the window
3. You should see a small popup. Click the arrow beside ‘Advanced options’, make sure the key length is 4096. For our purposes, we’ll uncheck ‘key expires’. Put your username where it says ‘full name’, fill out what you want for email, and create a secure passphrase. Check the picture for an example on how to fill it out. When complete, click ‘Generate key’
4. GPG Keychain will begin generating your key. Move the mouse around, mash keys in a text editor, have something downloading. Do random stuff to create entropy for a secure key.
5. annndddddd we’re done!

Part 3 – Setting up the environment

This is where OS X differs from other platforms. The suite itself doesn’t provide a window to encrypt/decrypt messages, so we need to enable some options.

Dark System Alpha Mac Os Download

1. Go into system preferences, open up ‘Keyboard’
2. 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 you can create keyboard shortcuts. We’ll uncheck everything OpenPGP that’s under ‘Text’, and delete their shortcuts. Now we’ll enable ‘Decrypt’, ‘Encrypt’, and ‘Import key’. Create keyboard shortcuts for these if you wish. Check the picture to make sure you’re doing everything correctly. You can now close the window.

Part 4 – Obtaining your public key

This part is super simple.

1. Open up GPG Keychain, select your key
2. At the top of the window, click ‘Export’
3. Give it a name, make sure ‘include secret key in exported file’ is unchecked, and click ‘save’
4. Open your text editor of choice, browse to where you saved the key, open it
5. There it is. Copy and paste this on your market profile to make it easier for people to contact you

Part 5 – Obtaining your private key

Again, super simple.

1. Open up GPG Keychain, select your key
2. At the top of the window, click ‘Export’
3. Keep the file name it gives you, check ‘Include secret key in exported file’, then click save

Keep this file in a safe place, and don’t forget your passphrase. You’re fucked without it!

Part 6 – Importing a public key

This is really easy.

1. Find the key you want to import.
2. Copy everything from ‘—–BEGIN PGP PUBLIC KEY BLOCK—–‘ to ‘—–END PGP PUBLIC KEY BLOCK—–‘
3. Paste it into your favourite text editor, highlight everything, right click, go to ‘Services’, then ‘OpenPGP: Import key’
4. You’ll see this window pop up confirming the key has been imported, click ‘Ok’
5. Open up GPG Keychain just to confirm the key is there

Part 7 – Importing a private key

Again, really easy.

1. Open GPG Keychain, click ‘Import’ at the top
2. Browse to where your key is, click it, then click ‘Open’. It should have a .asc file extension
3. You’ll see this pop up confirming your key has been imported. Click ‘Close’

Part 8 – Encrypting a message

1. Open your text editor of choice, write your message
2. Highlight the message, right click, ‘Services’, ‘OpenPGP: Encrypt’
3. A window should appear. Select who you’re sending it to, sign it with your key if you wish, click ‘Ok’
4. Copy everything, and send it to the recipient

Part 9 – Decrypting a message

Pretty much the same process as encrypting

1. Open your text editor of choice, paste the message
2. Highlight everything, right click, ‘Services’, ‘OpenPGP: Decrypt’
3. A window should pop up. Enter your passphrase, then click ‘Ok’
4. aannnddddd there’s your message

Part 10 – Conclusion

That wasn’t too hard, was it? Like I said in the intro, you shouldn’t be using OS X for DNM activities due to privacy issues, but I won’t go into it. This took forever to complete because OS X is a bitch to get running properly in a virtual machine. A guide for Windows will be coming next week!
