Google Calendar, Calendar, and SmartDay are probably your best bets out of the 4 options considered. 'Allows subscribing to public calendars through web client' is the primary reason people pick Google Calendar over the competition. This page is powered by a knowledgeable community that helps you make an informed decision. Apple Calendar (already included on Mac OS and iOS) This standard app combines iCloud, Google and Exchange calendars and can be very useful for those who have several accounts. Calendars can be divided into categories and marked with different colors. You can also sort calendars by location: work / home / travel and etc.
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:
- 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 or Big Sur?
While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes. If you have old 32-bit apps, they will not run in the new OS.
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:
- 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 (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.

Success relies on organization, and a calendar is one way that helps many people stay on track, meet deadlines, and organize their events. Apple’s built-in calendar app, iCal, is a go-to for scheduling - you can invite other attendees to events, link to maps, set notifications, and add events using natural language (if you type, “meeting with Joe at 2 pm Friday” and iCal will auto-create the calendarized entry).
However, greater functionality is required for scheduling many projects and events. Perhaps you need to access calendar information on multiple devices that aren’t all Apple products. Maybe you want to keep an editable to-do list inside your calendar app. There’s also the possibility that you just want an alternative to what comes standard on a Mac. Below you’ll find a roundup of the top calendar apps for Mac, as well as iCal add-ons so you can manage your schedule your way.
