The best Mac antivirus software in 2020. By Paul Wagenseil 20 November 2020. Bitdefender makes the best Mac antivirus software, but Kaspersky and Norton aren't far behind. The Best Mac Antivirus Protection for 2020. Despite what you may have heard, your Apple computer is not immune to malware. We test the top contenders to identify those offering the best Mac. There's also VirtualBox which is free and open source but much harder to setup and use. We think Parallels is the best way to run Windows on your Mac in 2020 for its ease of installation, speed, and the way it conveniently allows you to switch between macOS and Windows instantly. Apple OS concept redesign ( ux, ui, product, augmented reality, operating system, windows, apple, ios, safari, music, finder, design, motion, animation, 3d).This is a concept that I had in mind for a long time.

Windows, macOS – which one do you want to use today? On a traditional setup, you're stuck with one or the other. But with virtual box, you actually have macOS on a Windows PC.

It's the freedom that computer users have enjoyed with Linux and other operating systems.

But Apple has made it difficult to install their operating system on anything other than their own hardware. All of that is changing, and Virtual Box is responsible for it and the rise of the Hackintosh.

New to hackintosh? Learn more about it in our what is hackintosh? overview.

Note: A lot of people will be able to get a mac virtual machine one Windows running smoothly, but sound doesn't seem to work well. That's really not an issue because you'll still be able to access all of your apps and software.

I also recommend that you have access to a real Mac. You might be able to find some distributions of the High Sierra ISO online, but there is always a risk when downloading from an unofficial source. Instead, borrow a Mac from a friend, or use your own and download the High Sierra OS from the App Store.

Everything You Need to Get Started with Installing macOS on VirtualBox

Before we go through the steps on how to install macOS on Virtual Box, let's get everything together that you'll need to get started.

  1. Open up your Mac
  2. Go to the App Store
  3. Type in 'High Sierra'

You'll want to search for your desired operating system (we'll be using High Sierra), and Download it.

Note: You'll need a decent computer to be able to run Virtual Box. Your computer will need to meet these minimum requirements:

  • Dual core processor
  • 4GB Ram or higher
  • 64-bit

If your computer doesn't meet these requirements, you won't be able to run macOS properly. You'll be able to download VirtualBox from the official website. I'm not going to go through the installation process, as the website will have all of the information you need to be able to install VirtualBox.

I do recommend that you read all of the documentation and ask any questions that you have in the community section of the website.

VirtualBox 6.0 was just released, so it's definitely a great time to get started with your own macOS.

Extract macOS Sierra

Make sure you've downloaded High Sierra, and then you'll want to run a few commands from your terminal . You'll be able to open the terminal at: Applications > Utilities > Terminal. Once inside of the terminal, you'll want to run the following commands:

Go to your desktop and rename the file, removing the '.cdr' extension. You need this extension to read '.iso' for it to work properly.

You've successfully created your own ISO file so that you can bootup your macOS.

The next step is to copy the file over to your Windows machine (using a large USB drive seems to work best). This file will be mounted in your virtual machine later on in the article, so it's very important that this step is completed successfully.

Creating a mac Virtual Machine on Windows

You'll want to create a virtual machine, and this is really easy. You'll open up VirtualBox and click New. You'll want to have the following parameters selected or entered before clicking Next.

  • Name: High Sierra
  • Type: Mac OS X
  • Version: Mac OS X (64-bit)

Pay attention when selecting the version because you may find that High Sierra is offered as a version when you go to install it. But if it's not, you can just choose the settings I listed above and they should work fine.

You'll then be proceeding through all of the settings.

When you come up to the RAM setting, you'll want to be generous. VirtualBox requires a minimum of 4GB or RAM to run, but the more the better.

Why?

You'll want to provide at least 4GB to your macOS, or 4096MB to be precise. A general rule of thumb is that if you can spare it, supply more RAM to your virtual machine. RAM will allow the operating system to put more information into memory and retrieve it faster.

For better overall performance, supply as much RAM as you can.

The next steps are also important, and they'll include:

  • Hard Disk: Choose the 'Create a virtual hard disk now' setting.
    • Choose VDI when choosing the hard disk type.
    • Choose Fixed Size instead of Dynamic for added speed.
    • Set the size of the drive to at least 25GB.

You'll now have your virtual machine using the RAM and disk space properly, and you'll have to work your way through a few screen prompts before having everything setup properly.

Configuring Your VirtualBox to Run macOS High Sierra

We've made a lot of progress so far, and now it's time to configure your virtual machine properly. You'll see in the main window of VirtualBox that 'High Sierra' is listed. Click on this and then click on the 'Settings' button.

You'll want to go to 'System' and make sure that the following are unchecked on the Motherboard tab:

  • Floppy
  • Network

Click on the Processor tab and make sure that you have 2 or more CPUs set for your virtual machine.

The next few settings are rather simple:

  • Display: Video Memory with a minimum of 128MB
  • Storage: Click 'Empty' and then click on the CD at the top right. Choose your High Sierra ISO file

Now you'll need to click 'Ok,' and save all of the changes you've made. Close out your VirtualBox now.

Apple is very strict on the system that their operating system runs on, so it's very important that you do your best to configure your virtual machine in such a way that it tricks the installer to thinking you're on a retail machine.

We'll now be going into the Windowscommand prompt.

You'll do this by:

  • Clicking the Start Menu
  • Typing 'Command Prompt'
  • Right-clicking on the Command Prompt desktop app
  • Choosing Run as administrator

It's very important to follow all of the following command prompts exactly. Your goal is to run each command, one by one, hitting the Enter button and waiting for the command to complete successfully.

Remember that VirtualBox needs to be closed before running these commands, or it won't work properly.

You have to make sure that the virtual machine is properly named 'High Sierra' for this method to work. If not, you'll be able to go back and make changes to the name to get everything to work properly.

Once all of the commands are completed, and there are no errors, you'll then be able to open up your VirtualBox and get macOS High Sierra installed properly on VirtualBox.

It's a long process, but we're almost done with your installation.

Running VirtualBox and the macOS Installer

You've almost learned how to install macOS on VirtualBox entirely, and we're on the home stretch. You'll want to open up your VirtualBox and then click on your virtual machine that you set up earlier.

Now, click 'Start.'

There will be a lot of information displayed on the screen as everything starts running. I recommend stepping away from the machine and letting it run for a few minutes before coming back. Some errors can hang for 5 minutes or longer.

If you've done everything properly, you can be confident that the installer will boot properly.

You'll eventually be presented with the option to pick a Language. If you've reached this point, you're doing very well and are almost ready to run your macOS.

The next steps can be followed:

  • Choose your desired language, and click
  • Click 'Disk Utility' and then
  • Click 'View' and then 'Show All Devices.'
  • Click on your empty virtual drive that has been setup and click 'Erase.'
  • Choose the following settings:
    • Name: Macintosh HD
    • Format: Mac OS Extended (Journaled)
    • Scheme: GUID Partition Map
  • Click 'Erase' and close Disk Utility when the process is complete.
  • Click 'Reinstall macOS.'
  • Click 'Continue.'

You'll come up to one point where you'll be asked to choose a hard drive, and you'll want to select the Macintosh HD partition that you just created with the Disk Utility.

We've successfully copied all of the files on the virtual machine, but we're not done just yet.

Exit your virtual machine and then go back to your virtual machine's settings. You'll need to change up your Storage settings. Click on your ISO for High Sierra in the 'Storage Tree.' You'll click that CD icon just like we did earlier and then choose 'Remove Disk from Virtual Disk.'

You need to do this to unlink the ISO from your virtual machine.

Start up your virtual machine and you should come across a black screen with the EFI Internal Shell. You'll want to look for FS1. If this is listed in yellow, click on the virtual machine and then type fs1: and hit the Enter button.

You should be in the fs1 directory.

Type in the following commands:

  1. cd 'macOS Install Data'
  2. cd 'Locked Files'
  3. cd 'Boot Files'

Now we'll run the installer by running: boot.efi and hitting enter.

If everything goes well, you'll come across a graphical installer and will just have to work through the prompts. The virtual machine will reboot eventually and then you'll need to go through the settings and the rest of the setup process.

Soon enough, you'll be right inside of macOS, where you'll be able to start using your mac virtual machine on Windows.

Having a virtualbox mac OS is the easiest method of using mac as and when you need it. In addition, using virtualbox is far less complicated than the dual boot hackintosh method we have looked at previously.

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. How to get mw2 for free on mac.

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

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.

Mac os 2020 update

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. Free download jw player latest version for windows 7.

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.
