Part 1: How to Make a MacOS Big Sur ISO File [11.4]

lse May 26th, 2021

How to make a macOS Big Sur iso from Leonidas Savvides

MacOS ISO Bg Sur 11.x.x

If you do not want to create an ISO – or you have Not a Mac – download ready iso from: BigSur_11.4.iso here …

1

How to Download Full MacOS Installer from Mac Command Line

DOWNLOAD Here Code

1-Followed this:

https://osxdaily.com/2020/04/13/how-download-full-macos-installer-terminal/

softwareupdate --fetch-full-installer --full-installer-version 11.4

# 11.4 is the most recent stable version as of this writing [slides 3-5]

2-Followed this:

https://osxdaily.com/2020/12/14/how-create-macos-big-sur-iso/

In your Applications you must have a “Install macOS Big Sur.app”

[slides 7-8]

3-After CMD Line commands continued
[slides 10-11]

1-First, we must create a temporary disk image:

hdiutil create -o /tmp/MacBigSur -size 14000m -volname MacBigSur -layout SPUD -fs HFS+J

2-Next, mount the disk image:

hdiutil attach /tmp/MacBigSur.dmg -noverify -mountpoint /Volumes/MacBigSur

3-Now we’ll use the createinstallmedia utility that is part of the MacOS Installer application to copy the installer files to the disk image you just created:

sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MacBigSur --nointeraction

4-Unmount/Detach the disk image volume

When finished, we then unmount/detach the disk image volume [slides 13-15]:
1-way
hdiutil detach /Volumes/MacBigSur/
2-way – if 1-way not working
Detach from Disk Utility

5-After unmount/detached the disk image volume continue in the Terminal [slide 17]:

We convert the freshly created macOS Installer disk image file to a CDR file that will appear on the desktop:

hdiutil convert /tmp/MacBigSur.dmg -format UDTO -o ~/Desktop/MacBigSur.cdr

6-Finally, we change the file extension from .cdr to .iso [slide 19]:

mv ~/Desktop/MacBigSur.cdr ~/Desktop/BigSur.iso

7-Conclusion [slide 20]

Now you have an iso file of Big Sur 11.x to use to install macOS Big Sur as VM in Hypervisors like VMware Workstation Pro [Windows/Linux], VMware Fusion [Mac], VirtualBox [Windows/Linux/Mac],…!

Docker vs Hypervisor — Containers vs Virtual Machines

Wednesday, April 21, 2021

Category \ Technology	Docker [Containers]	Hypervisor [Virtual Machines]
Docker vs. Virtual Machines
OS Support and Architecture	No Guest OS, Docker containers hosted on a single physical server with a host OS, which shares among them. Sharing the host OS between containers makes them light and increases the boot time. Docker containers are considered suitable to run multiple applications over a single OS kernel.	Host OS and the Guest OS inside each VM. Guest OS can be any OS, like Linux or Windows, irrespective of host OS.

Security	Providing root access to applications and running them with administrative premises is not recommended in the case of Docker containers because containers share the host kernel. The container technology has access to the kernel subsystems; as a result, a single infected application can hack the entire host system.	Virtual machines are stand-alone with their kernel and security features. Applications needing more privileges and security run on virtual machines.

Portability	Docker containers packages are self-contained and can run applications in any environment, and since they do not need a guest OS, they can be easily ported across different platforms. Also, containers being lightweight [MBs] can be started and stopped in very less time compared to virtual machines	VMs are huge in size [GBs] because each include standalone OS. Not easy moved to a different platform without incurring compatibility issues.

Category \ Technology	Docker [Containers]	Hypervisor [Virtual Machines]
Docker vs. Virtual Machines

Performance	The lightweight architecture of Docker containers is less resource-intensive than virtual machines. Most times one application per Container.	VMs are more resource-intensive than Docker containers as the virtual machines need to load the entire OS to start. One OS in each VM, and usually many apps running in this OS.

Boot-Time	Boots in a few seconds.	It takes a few minutes for VMs to boot.

Runs on	Dockers make use of the execution engine.	VMs make use of the hypervisor.

Memory Efficiency	No space is needed to virtualize, hence less memory.	Requires entire OS to be loaded before starting the surface, so less efficient, more memory.

Isolation	Prone to adversities as no provisions for isolation systems.	Interference possibility is minimum because of the efficient isolation mechanism.

Deployment	Deploying is easy as only a single image, containerized can be used across all platforms.	Deployment is comparatively lengthy as separate instances are responsible for execution

Usage	Docker has a complex usage mechanism consisting of both third party and docker managed tools.	Tools are easy to use and simpler to work with.

Reuse of Resources and Libraries	Docker Containers can reuse Resources and Libraries from other Containers, taking less disk space.	No reuse between VMs, Redundant copies exist, demanding more disk space.

Usually, Organizations are making use of the hybrid approach mostly as the choice between virtual machines and Docker containers depends upon the kind of workload offered.

The best way to search for a Laptop or Desktop Computer

lse October 2nd, 2020

The best way to search for a Laptop or Desktop Computer medium to high priced for a purpose eg Software & Web Development or another item is just to create something for this in a related channel, like a YouTube video, blog article, Presentation, Excel Info/List, an Infographics, or other…

Create something RELEVANT
YouTube video mp4 or/and // eg “best laptops for software development in every budget”
Presentation Pptx or/and
Excel sheet/list xlsx or/and
Blog articles WordPress or/and
?…or another item, just create something in relation to this item, its category, or its usage…

This also the case in case you read a textbook/book especially in Programming
After finish reading a chapter or section, practice examples, do exercises in code by typing scripts and run code in IDE, Emulator, Browser,…etc
In addition, you will get embedded in your head, more what you have read by implementing an App with related programming as the chapter you read or write a guide how-to in programming related in your blog,…

I learn this by creating a YouTube video & Blog post & Presentation [all these] for my blog, about buying a laptop for specific needs[particularly Software Development] in different budgets, I learned a lot about the laptops market – even the laptop market local or online is huge… like many hidden secret models of laptops – were in the market but un-noticed… to me!!!
