# Start the VM, make sure that CDROM with datastore ISO (Catalina.iso) is connected |
# Disable the Network boot option in vSphere BIOS menu. Restart VM |
# Installer should start. You should choose Disk Utility, and initialize the VMware Virtual SATA Hard Drive Media |
# (since keyboard ain't work - using existing `Untitled` name) |
# Wait util installer completes. VM will not boot. Shutdown VM, change Guest OS profile back to `Other:Apple macOS 10.14 64-bit` |

- Option 1 – The Apple Script – Creating macOS Install Media on a USB drive. After downloading the right file from the Apple App Store: Now Apple is not totally ignoring the end user when it comes to making install media – it’s well hidden (in my opinion) in this Apple Knowledge Base article. The Install application would have been much more user friendly experience, if Apple would have.
- I have Mac OS X Mountain Lion as Application Bundle file. Burning the application to a disk is just like a data disk compilation on Nero. How do I convert this application bundle into ISO image so.
Webcams for mac. Thanks! This actually worked with macOS Catalina 10.15.4 Build 19E287 and VMware Fusion Professional Version 11.5.3 (15870345). The Fusion vm showed the Apple logo and booted straight into Recovery Mode. |

An ISO file contains optical disc file system and contains elements that would be written in optical disc. It comes with .iso extension but sometime .img extension is also used in some cases like Microsoft Dreamspark.

It is sector by sector copy of data.
What is ISO FILE
The full form of ISO is International Organisation for Standardization. The ISO name is taken from ISO 9660, used with CD ROM media but it contain a UDF(ISO/IEC 13346) file system ( used for DVDs and Blu-ray Discs). Most of the operating systems like Unix, Linux and Mac OS have built in capability to mount an ISO. Most of the emulator uses .ISO file to create image of CD. Emulator like PCSX2, Dolphin use .iso to emulate Wii and GameCube games and Playstation 2 games respectively.
Benefits of ISO file
- It is the program file which is neatly copied in a single file and it is used to distribute large program over the internet.
- It is used to create backup of CD or DVD because it creates the exact copy carry, and converts all the data with bits from the disc. Whenever the file is copied, it lacks the header file but when iso file is created it covers all the things including the header file.
Softwares used to create iso file
- ISO Recorder
- Magic ISO
- Power ISO
- Any to ISO

We have so much in Mac that would make it easy for us to convert an ISO file to DMG and DMG file to ISO and also no additional software is required. Although there are some processes that would be used to convert the DMG file into ISO file in Mac OS X.
The first process is by using opening disc utility , the second process comes with the command line and the third via different software.
Opening Disc Utility
This is a powerful technique. We should be careful while doing this because by our single mistake it would easily wipe out data from some of our discs. So be cautious.
