You may be wondering what more does the macOS 11 Big Sur have to offer you? Well find out for yourself, you even can in Windows, first you’ll need to learn how to install macOS 11 Big Sur on VirtualBox on Windows PC. And don’t worry we will instruct you how to.
Download Big Sur InstallAssistant.pkg (9GB) either inside the virtual machine or on the host on a disk image that will be mounted on the virtual machine. Windows can create and mount VHD disk images through Disk Management.
Use VirtualBox to create an additional disk image that’s has at least 60GB of space. Attach it to the virtual machine and erase it with Disk Utility, formatting it to APFS.
Run InstallAssistant.pkg which creates an “Install macOS Beta.app” in the /Applications folder
Run “Install macOS Beta.app”, select “Show All Disks…” and select the new empty disk.
Allow the installer to complete. When the macOS initial setup starts, shut down macOS with Command-Q

Once you have named your virtual machine and decided upon the RAM Usage it is next going to ask you what Hard Disk you want the Virtual Machine to use. You will see three options, do not add, create or use an existing one. Select “Create a Virtual Hard Disk” with 100GB and browse to where the “macOS 11 Big Sur..vmdk” file was located and then finally click create!

How to see WiFi passwords saved on CatalinaMac
Before showing you how to see WiFi passwords saved on Catalina os x , I want to remind you that it is not possible, at least with this method, to find the key of a wireless network to which the computer has never connected. The Mac need not be connected to it right now. However, it is important that the wireless network has been used in the past, at least once. In addition, as I said, to find the secret combination you need to know the SSID , or the name of the Wi-Fi network.
That said, two methods can be used to view WiFi passwords saved on Catalina os x . The first is the one that uses the Keychain Access software. The second is the one that foresees the use of the Terminal on Catalina os x. There is no difference in the result obtained. Below, find both procedures.
How to find wifi password on Catalina with Keychain Access
If you’re wondering how to see WiFi passwords saved on Mac , the most common tool you can use to find out is Keychain Access .
Once open, in the Keychain sidebar, click System. You will see a list of stored keys. Order by Name with one click. Then, locate and choose the WiFi network of your interest. After opening the dedicated tab, to see WiFi passwords saved on Mac, from the Attributes section, enable the Show password flag.
By doing so, you will see the warning ” Keychain Access would like to make changes “. Type your Username and Password to allow the action. Then, click Ok. If you see another similar warning, confirm your credentials again, and select Allow. At this point, next to Show password you will be able to see the stored WiFi key. Write it somewhere and close.
How to find wifi password on Catalina without Keychain Access using terminal

To proceed, first open the Launchpad , go to Other and click on Terminal . When the command line interface appears, type the following:
Once the command has been written, change the script nome-rete-WiFiI highlighted by entering the name of the WiFi network whose password you want to know. Then, hit the Enter button .
If you typed correctly and if the wireless network was already connected, you will see the warning to allow access to the MetadataKeychain . Click Allow and, if prompted, enter your username and password.
After that, you should see an output containing the stored Wi-Fi password , like this:
password: " WiFi-password "
In some cases, you may not be able to see WiFi passwords saved on Mac because you receive the following error :
security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain.
If you are sure that the name of the wireless network is correct and that the Mac has connected to it at least once, check the quotes in the command. It doesn’t have to be these “ but these ".
In addition to the substance, curiosity: every year the name chosen by Apple for the new version of macOS is eagerly awaited. Will it be Mammoth, Monterey, Skyline or something different this year?
The tradition of naming the major releases of operating systems for their computers dates back to Mac OS X, when Apple began to choose feline names and then, in 2013, move on to names related to California with OS X Mavericks.
Just in 2013, it was discovered that Apple had registered over 20 California-themed brands for future versions of macOS. Over time, some of those brands like Yosemite, Sierra and Mojave have actually been used by Apple for its Mac operating system updates, while many others remain unused and others have been abandoned.
Shortly before WWDC 2019, only the trademarks of the Mammoth , Monterey , Rincon and Skyline brands remained active under Apple’s name . Anyone registering a trademark in the U.S. has 36 months from the approval date to file a usage declaration demonstrating their intention to use that trademark. This “intention” can be renewed every six months before that trademark is put on the market, for a maximum of 6 further renewals before the company loses all rights to that trademark.
In 2019, Apple used the name Catalina which was not present in the previously registered names, but it was an exception and this year the company could return to its original list. In this case, the available names are only three of the four already listed before, given that “Rincon” was abandoned in September 2019 after the 36-month deadline. Mammoth, Monterey and Skyline remain active:
Mammoth probably refers to Mammoth Lakes and Mammoth Mountain, very popular areas for those who love skiing and hiking in the Sierra Nevata mountains. The brand was registered in March 2019 and was renewed in March 2020.
Monterey is a historic city and a popular vacation spot on the Pacific coast. The brand was registered in December 2013, but the authorization did not arrive until June 12, 2018. The last renewal request was made a few days ago.
Skyline probably refers to the scenic Skyline Boulevard that follows the crest of the Santa Cruz mountains south of San Francisco.
So what will macOS 10.16 be called? Mammoth, Monterey and Skyline all seem valid options, but the company could follow the example of 2019 and propose a macOS 10.16 with a totally surprise name. Furthermore, given that macOS 10.16 will still be related to Catalina because it will have few substantial innovations, the name could be connected to this location: macOS Channel Islands (the group of islands of which Catalina is part) or macOS Avalon (the only city in the Santa Catalina island in California).
