thank you for the opportunity to save a lot of time by installing a bunch of incomprehensible programs!

Great tutorial, man. Thanks for uploading. The link for the command doesn't seem to be right anymore, though. I had to pause the video and manually type the command you had in the Terminal, which is okay for me, but some people might be uncomfortable with that.

idk what im doing wrong but the commands in terminal dont work for me....

Hello @TechLunar
Thank you for this great tutorial!! - I want to do this to install Mac OS High Sierra on my 2017 iMac - running Ventura - in a VMWare virtual environment.
I have the download that I copied to a Thumb Drive from another Mac running OS High Sierra.
Some people say all that is needed is the "InstallESD" File, which I have copied to my Mac Desktop. I also have the "Install Mac OS High Sierra" file that I copied from my Thumb Drive, on my Desktop.
Do I need to save the complete "Install Mac OS High Sierra" file to an ISO --- or -- convert the "InstallESD" file to an ISO in order to attempt to mount it

Thank you for your video!!

Don’t get how you copy and pasted the command

One question. Is some difference between start iso file and end one?

[beautifulandbest]

How can we backup whole mac OS partition to iso file if there will be any issues with hard disk so we can reinstall that iso using bootable USB and get all our data back

[DorianoPaisanoCarta]

Why does the Mac create image files with the .CDR extension and sometimes .dmg extension? What determines that and what are the differences?

[brianschumacher]

Do you know if the ISO would be bootable if I burned it to a DVD?

[rumble]

hdiutil errors out with bus error for me... annoying.

Edit: switching to bash instead of zsh has better error messages. seems my image cannot be attached so it can't convert to iso

[cheavideography]

I have this message every time I tried: attach of disk image failed: 35 how can I fix it?

[ronservice]

Worked just like you said When i add the iso file to Basilisk II and run it I get a message saying the disk is unreadable. I am trying to open old files created in Microsoft Works V2 thru an emulator (Basilisk II). Were am I going wrong?

[deathvai]

im having troubles finding the files for the iso to work. i can download a iso off windows offical website but when i try to run it i get a message saying that i am missing boot up stuff and other things. do you have any links or recomendations of where i can obtain the files?

[southy]

It's not letting me point it toward desktop...no matter how many times I put in the

[Heonsksksmz]

[Prod.BluBeats]
