macOS 10.15.5.

Catalina Mac OS 10.15. was just released on the 26th of May macOS Catalina. It is still in beta but could be downloaded from developer.apple.com if you have a developer account. New features that this update will bring to Mac is a battery health feature that is supposed to reduce the rate at which the device's battery ages. This feature will analyze the charging patterns of the battery and the current state of its health and then control the extent to which it would get charged so as to slow-down chemical aging. This feature can be turned on and off from System Preferences > Energy Saver.

Even though macOS Big Sur version beta 8 is out. In this next post, you will receive information about the latest final macOS version – macOS Catalina. We will tell you about the changes and improvements that have been brought to Mac with this newest operating system and we will also briefly mention some of the more notable features of previous macOS releases.

Additionally, you will learn how to check the current macOS version on your Mac as well as how to upgrade and downgrade it.

The latest operating system for Mac is called Catalina (mac OS version 10.15.5) and it is the sixteenth major upgrade for macOS. As of May 2020, it has become the current operating system for Mac computers. Its name is inspired by Santa Catalina Island, an island located in California's Channel.

Notable changes made with macOS Catalina are the removal of iTunes, the addition of the Sidecar feature, the expansion of the iPhone and iPad Screen Time featureto Mac computers, and others. Additionally, significant changes have also been made to the macOS security. Below, we will have a quick look at each of these improvements:

The CPU and TurboBoost function have been both optimized for an increased battery life. It works by shutting off CPU cores but allowing for a higher frequency rate on working cores to sustain performance.

iTunes has been a part of Mac computers ever since 2001 but with Catalina, it has officially been terminated. Now, with the latest macOS release, instead of iTunes, users will have access to three separate apps that together take over the functions of iTunes. Those apps are Music, TV, and Podcasts.

As for managing your devices, with Catalina, this is done via Finder and not via an app.

This feature allows Mac users who also own an iPad to turn their iPads into second screens for their Mac computers. The Mac screen could be extended to the iPad or they could both show the same content (mirror screen). Sidecar also works with Apple pen, enabling users to use their iPads as drawing tablets.

This is an iPhone and iPad feature that, with Catalina, has been carried over to Mac computers. Screen Time allows you to track the usage of all your Apple devices, providing useful information on how your time is being spent across them.

The Find My app implements the Find My Mac and Find my Friends technology to provide users with the ability to potentially find their lost/stolen device. This technology does this by employing Bluetooth and the help of other devices that are near the lost/stolen one.

One of the biggest changes made that came with Catalina is related to the security of the macOS.

The first improvement is the Read-Only system volume – a dedicated system volume that allows Catalina to run separately from other data, thereby preventing any potential attempts at tampering with system files done by malware and hackers.

Next, the Gatekeeperfeature, which previously only used to check the sources of new apps, now also checks the apps themselves and prevents them from running if it deems them potentially unsafe.

Thirdly, unlike earlier macOS releases, Catalina requires explicit user approval if an app wants to access data stored in the Desktop, Downloads, and Documents folder. Only after the user gives their permission would the app be able to gain access to such data.

One other notable change is that 32-bit apps can no longer be run on Mac computers if the latter have been updated to Catalina, making macOS Mojave the last macOS release that supports 32-bit apps.

Older versions

In this section of the article, we will briefly go over the older macOS releases and the most notable changes they've introduced, starting with the leaser recent one:

Yosemite (10.10) – released on the 16th of October, 2014

Yosemite overhauled macOS's user interface and introduced the Continuity and Handoff features which improved and expanded pairing between iOS and macOS devices. Receiving phone calls and text messages was now possible on either device and so was editing same documents across devices.

Later on, a Yosemite update replaced Aperture and iPhoto with Photos.

El Capitan (10.11) – released on the 30th of September, 2015

This macOS release was focused on system performance improvements and changes to already existing features. Public transport information was made available in the Mapsapp, the Notesapp received interface improvements, and the Metal API performance-enhancing app was officially introduced to macOS.

Sierra (10.12) – released on the 20th of September, 2016

Sierra brought Siri to Mac computers and added several Mac-exclusive features for the app. Improvements were also made to the iCloudapp, which could now store user data from the Desktopand Documentsfolders, allowing syncing of those folders with other Macs that share an Apple ID. Additionally, Sierra website support for Apple Pay through the use of a nearby Touch ID or iOS device for authentication.

High Sierra (10.13) – released on the 25th of September, 2017

Most improvements here were 'under-the-hood' – High Sierra brought improvements to VR support, as well as to apps such as Safari, Spotlight, Notes, and Photos. High Sierra was the first to start using Apple File Systemand it also introduced the successor to the Metal API performance-enhancement application – Metal 2.

Mojave (10.14) – released on the 24 of September, 2018

New features introduced by Mojavewere the Dynamic Desktop, Desktop Stack, and Dark Mode. Several iOS-exclusive apps such as Home, Apple News, and Voice Memoswere also carried over to macOS.

How to check the current version on your Mac

In order to find out what your current macOS version is, click on the Apple menulocated in the top-left corner of your screen and then select the option labeled About this Mac. The current version of your macOS will be shown at the top of the Overviewtab. If it says that your current version is macOS Catalina 10.15.14, then it means that your Mac has the latest stable macOS version. If you see any other version written there, you may want to update your Mac to Catalina 10.15.14 (see below)

How to update to the latest macOS version

To get the latest macOS version, you must open the Mac App Store and search for Catalina. Once you find the Catalina update, click on the download (Get) button and wait for the download to complete. Since the update is nearly 5 GB, downloading it may take a while, just be patient. Once the update has been downloaded, the installer will be launched automatically. To install the update, simply follow the steps from the installer.

How to downgrade macOS version (using Time Machine)

Note that in order to perform this downgrade with the help of Time Machine, you will need to have first created a Time Machine backup disk from when you still had the earlier macOS version. If you have such a backup, here's how to use it in order to downgrade your OS.

Warning: It is highly advisable that you back up any important data you've created or downloaded since your Mac got updated to the Catalina OS. Otherwise, such data would be lost after the downgrade!

• Mac OS X

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.

The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2020 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.

How to Tell Which macOS You Are Running

To find out which macOS is currently running on your Mac, follow these steps:

1. Click on Apple logo in the top left corner of the menubar
2. In the dropdown click on the first item: About This Mac
3. 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

Yahoo News

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 or Big Sur?

While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes.

The first issue is compatibility.

Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM.

After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected.

However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.

The second breaking issue is the lack of 32-bit app support.

macOS Catalina and Big Sur can only run 64-bit apps.

If you wondering whether you should upgrade to macOS Catalina or Big Sur, 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 the 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:

1. Click on Apple logo in the top left corner of the Mac screen
2. Click on About This Mac option
3. Click on System Report button in Overview tab (first one)
4. Scroll down to Software -> Applications
5. 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 (or better High 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 to get 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

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.
