  3. The Original Mac OS Demo - YouTube Behold, one of the first ever versions of Mac OS (first known as Macintosh System Software) that was released in 1984. I will be demoing this vintage softwar.
  1. Lashbrender Demo Mac Os Catalina
  2. Lashbrender Demo Mac Os Pro

Every major version of Mac OS X macOS has come with a new default wallpaper. As you can see, I have collected them all here.

Lashbrender Demo Mac Os Catalina

The playable Kerbal Space Program demo, version 0.18.2. Note that this file is for the Mac OS X based operating systems only. This new demo is based on KSP 0.18.2, so it has all the newer systems, with several restrictions, of course.

While great in their day, the early wallpapers are now quite small in the world of 5K and 6K displays.

10.0 Cheetah & 10.1 Puma

The first two releases of Mac OS X shared the same wallpaper. The sweeping blue arcs and curves helped set the tone of the new Aqua interface.

10.2 Jaguar

Jaguar took the same Aqua-inspired theme but added some depth and motion to things. In my head, the trails streaking across the screen were from a set of comets.

10.3 Panther

While Panther inflicted Macs everywhere with Brushed Metal, its wallpaper stayed on brand, refreshing the original 10.0 image.

10.4 Tiger

Many consider Tiger to be the best “classic” version of Mac OS X. While that may or may not be true, it is my favorite Aqua-inspired wallpaper.

10.5 Leopard

Complete with a revised, unified user interface and shiny new Dock, 10.5 broke the Aqua mold. As such, Leopard was the first version of OS X to break from the Aqua-themed wallpaper. It ushered in the “space era” of OS X wallpapers, which was used heavily in the new Time Machine interface as well.

10.6 Snow Leopard

The “no new features” mantra for Snow Leopard didn’t ban a new wallpaper, thankfully. This starscape is still one of my favorites.

10.6 Snow Leopard Server

The server version of Snow Leopard came with its own unique wallpaper that is a real treat:

10.7 Lion

Lion kept up the space theme, this time showing off the Andromeda galaxy. The space nerd in me likes the idea, but the execution of this one leaves dead-last on my list of favorites.

10.8 Mountain Lion

Just like Snow Leopard before it, with Mountain Lion, Apple opted to clean up and revise the existing theme as opposed to changing directions for what would be a less-impactful release of OS X.

10.9 Mavericks

Lashbrender Demo Mac OS

Mavericks marked the beginning of Apple’s “California location” naming scheme for Mac releases. The wave depicted looks as intimidating as the ones in the famous surfing location.

10.10 Yosemite

Yosemite brought another UI refresh to the Mac, making things flatter and more modern. The wallpaper ushered in a new era based on … well … mountains.

10.11 El Capitan

Named after a breathtaking spot in Yosemite National Park, El Capitan was a clean-up year after 10.10.

10.14 Mojave

No more mountains! Mojave brought a new system-wide Dark Mode, and the OS shipped with two versions of its default wallpaper to match. Users could even have macOS slowly fade between the two background images over the course of the day.

10.15 Catalina

macOS Catalina brought big changes to the Mac, including the ability to run iPad apps natively, opening the platform up to a much larger number of developers than ever before. Catalina shipped with multiple variants of its default wallpaper, and the ability to shift between them as time progresses throughout the day:

macOS Big Sur

This version of macOS is such a big deal, Apple changed the version number to 11.0. It will be the OS that brings support for Apple Silicon-powered Macs, and features a brand new design.

With Messages for Mac, you can send unlimited messages to any Mac, iPhone, iPad, or iPod touch that uses iMessage, Apple's secure-messaging service. iPhone owners can use it for SMS and MMS messages, too.

Set up iMessage

iMessage is the Apple messaging service you get automatically with your Apple ID.If Messages asks you to sign in, use the same Apple ID that you use with Messages on your iPhone and other devices. It's usually the same Apple ID that you use for iCloud, the iTunes Store, the App Store, and the account you created when you first set up your Mac.

Learn what to do if you get an error when trying to sign in to iMessage.

Have a conversation

  1. Click the New Message button at the top of the Messages window.
  2. Type the recipient's name, email address, or phone number, or click and choose a recipient. If they're in your Contacts app, Messages finds them as you type. To start a group conversation, just add more recipients.
  3. Type your message in the field at the bottom of the window, then press Return to send it.
    • To include emoji, click .
    • To include an image or other file, just drag or paste it into the message field.
    • To include an audio recording, click and record your message.
    • To add other items, such as Memoji stickers, GIFs, and message effects, click the apps button .
  4. After starting a conversation, click the Information button (or Details) in the upper-right corner of the window to take actions such as these:
    • Use FaceTime to start an audio call or video call .
    • Share a screen .
    • Hide alerts, so that you aren't disturbed by notifications about the conversation.
    • Share your location temporarily or indefinitely, or send your current location. You can also see the recipient's location—if they're sharing their location with you.
    • See all of the photos and files that were exchanged in the conversation.
    • Customize the group, such as by changing the group's name or photo, adding members to the group, or leaving the group. If the group has four or more members, you can remove members: Control-click the member's name, then choose Remove from Conversation.

New in macOS Big Sur

macOS Big Sur introduces new features to improve conversations:

  • Pin a conversation to the top of the conversation list so that you can quickly get to it. Just Control-click the conversation to open a shortcut menu, then choose Pin.
  • Help bring your message to the attention of a group member: Either click their name after you type it, or include the @ symbol before their name: “@Jocelyn, see you then!” When you mention someone, their name is highlighted in the message, and they will receive a notification letting them know they’ve been mentioned.
  • Create an inline reply to a specific message in a conversation: Control-click the message to open a shortcut menu, then choose Reply. Or click a bubble to select it, then press Command-R.

  3. Click a Tapback to add it to the message bubble.

Here's another way to add a Tapback: Click a bubble to select it, then press Command-T.

You can also use Siri to send, read, and reply to Messages. Examples:

  • ”Send a message to Susan and Johnny saying I'll be late' or ”Tell Johnny Appleseed the show is about to start” or ”Text a message to 408 555 1212.”
  • ”Read the last message from Brian Park” or ”Read my new messages.”
  • ”Reply that's great news” or ”Tell him I'll be there in 10 minutes.”
