Mac OS X is finally finished, with Apple confirming that it's officially moving to macOS 11 with the newly announced Big Sur update after almost 20 years of OS X (or macOS 10.) That means that. Everything Apple just announced at WWDC 2020: iOS 14, MacOS Big Sur, new Mac chips Apple silicon is real and the company's stoked about the new chips. But for some, the updates to Siri, Memoji. All University Mac users are strongly advised to upgrade from OS X Yosemite operating system to macOS Sierra (v10.12.6), as soon as possible, as Yosemite is no longer supported by Apple. The upgrade will help to ensure that Macs have the latest security, features, and remain compatible with other University systems. Launched in October 2019, macOS Catalina is Apple's latest operating system for the Mac lineup. Features include cross-platform app support for third-party apps, no more iTunes, iPad as a second.

This guide will help you become familiar with Mac OS X — the operating system of every Mac. In just a few, short steps, this article will teach you everything you need to know to get started with your Mac.
Mac OS X — The Basics
Mac OS X is the operating system of your Mac. It's the basic system that enables your Mac to work. All the files, folders and programs are handled by Mac OS X as well as internet connectivity, battery consumption and more.
As a Mac user, you will encounter Mac OS X in many different forms:
- When viewing the desktop
- When you're browsing through files
- Through the Mac's search function (called 'Spotlight')
- Through the application bar (called 'The Dock')
- As the system that runs your applications
…and much more. Mac OS X is always there in the background, making sure your Mac runs smoothly. By learning more about Mac OS X, you will become a more efficient and confident Mac user. Let's get started!
Mac OS X — An Overview
The home of your Mac is the desktop. Think of it as a physical desktop – a place where you may temporarily spread out your work while performing a task.
For example, you may put an image from the internet on the desktop, make some modifications, and then drag it into an email. Just remember, while the desktop is a great workspace it not a good place to store files long-term since it quickly gets messy — again, just like an actual desktop.
Let's have a look at the other things you see in when you first turn on your Mac.
The Dock
In the bottom of your screen, you should see 'the Dock' — a bar with convenient shortcuts to your favorite applications. If you don't see it by default, try moving your cursor to the bottom of the screen and it should pop right up.
The icons in the Dock are just shortcuts. You can add or remove icons from the Dock without affecting the actual applications.
To add an application shortcut to the dock, you can use Launchpad, which is a complete overview of all your applications. You can probably find Launchpad in the left part of your Dock. Click Launchpad to view all your applications, then drag any icon into the dock to create a new shortcut.
Another way to add shortcuts to the Dock is to find the Application file (in the Applications folder) and drag it to the Dock. This requires some familiarity with browsing through files.
To remove an item from the dock, just drag it out and hold it over the desktop. After a second or so, a 'remove' label shows up. Release the icon and the application shortcut is removed from the Dock.
Menus
At the top of the screen you will see some menus. These menus change depending on what application you are using at the moment.
If there is ever anything you want to do in a certain application, try to find it in these menus.
Menu extras
Look at the top of your screen. To the right of the menus you are most likely to see a few symbols.
These little icons are mostly used to quickly edit your Mac's settings. Rather than having to open System Preferences, you can change the settings using Menu extras.
To change what Menu extras are visible, open System preferences. Click a preference pane and look for the checkbox that lets you choose if you want the specific Menu extra to be visible or not.
Users
Mac OS X offers a really nice way to switch between the different user accounts on the Mac. Near the upper right corner of your screen you will find your name. Click it and a list of all the users on the computer will appear.
Now, just click another user in order to log in to his/hers account (password may of course be required).
Spotlight
If you look at the upper right corner of your screen, you will see a small magnifying glass. This is Mac OS X's search function. It is called Spotlight. To read more about it, click here.
Dashboard
Mac OS X has a great thing called Dashboard where you can run mini-applications called widgets. Read the article about it, Dashboard is awesome.
Which Mac operating system is the best is a topic of numerous debates among Apple fans.
Since the mission of this blog is to refute myths and legends around Macs, it's time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.
TLDR; The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2019-2020 it is macOS Catalina. However, users that need to run 32-bit applications on Mac should not go with Catalina because it only supports 64-bit apps. Also, older Macs would benefit if upgraded at least to macOS Sierra because this is the earliest operating system for which Apple still releases security updates.
Update: On WWDC 2020 Apple announced a new macOS Big Sur, which is said to have the biggest UI redesign and the biggest Safari update. New Safari will run 50% faster than Chrome and use less battery. It also has new limitations: Big Sur will require at least MacBook Pro late 2013, MacBook Air 2013, and Mac Mini 2014 or later to run. Big Sur will be released in the fall of 2020.
How to Tell Which macOS You Are Running
To find out which macOS is currently running on your Mac, follow these steps:
- Click on Apple logo in the top left corner of the menubar
- In the dropdown click on the first item: About This Mac
- The first line in the Overview tab is the name of the current OS.
What Version of OS Can My Mac Run?
Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations.
For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.
Check below to know exactly what version of OS your Mac can run.
Which OS is Best for my Mac
Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.
Should I Upgrade to macOS Catalina?
While personally I like macOS Catalina and have it installed on my MacBook Pro, Catalina comes with serious breaking changes. If you have old 32-bit apps, they will not run in the new OS. macOS Catalina and newer can only run 64-bit apps.
If you wondering whether you should upgrade to macOS Catalina, first verify that you don't have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after upgrade.
For instance, I had to remove uTorrent after upgrade. And I didn't know that uTorrent is 32-bit!
How to Know If App is 32-bit or 64-bit
To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:
- Click on Apple logo in the top left corner of the Mac screen
- Click on About This Mac option
- Click on System Report button in Overview tab (first one)
- Scroll down to Software -> Applications
- Find the app and check Kind
Which macOS Should I Use
If you have an older Mac which is not eligible to upgrade with some latest software or hardware, I'd suggest upgrading at least to Sierra for the following reasons:
- Sierra is still supported by Apple, and it gets security updates
- APFS file system is available
- It supports Siri
- Significant security improvements
The most important point when choosing the best OS is the ability getting security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page.
For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan's end of life date was August 2018.
Snow Leopard Myth
I know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.
Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn't want to switch to new versions, because the old one was rock solid.
I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs.
After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.
How to Update to the Latest Version
There are two ways to update to the latest OS version on Mac:
- From the Software Update section in System Preferences
- Use a download link
Using Software Update
Apple Operating System Names
This is by far the best option, but it only available if you have Yosemite, or later OS installed already. If you enabled automatic updates, then Mac will inform you that the next macOS is available.
Just open System Preferences, go to Software Update and click on the Upgrade Now button.
This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here.
For instance, my the latest version for Mac Mini 2012 is Mojave, I can't install anything newer than that.
Using download links
For older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.
After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade.
