Please help. Fot some reason my mac won’t recognize any of the DVD-r that I use trying to burn a DVD with Toast. I want to convert an iso file to dmg so I can burn a bootable ubuntu install usb.

And as usual all of the sources that show how to do convert with hdiutil either give different ways, and or, tell you what to do but now how to do it. I realize that any linux nerd would know what they are talking about, but I am confused and do not understand the basic command principles to write commands, file paths etc. Below there are some of the suggestions.

So on my Mac, the ubuntu iso is on my desktop. And that is where I would like the dmg to be placed.

Thank you. P.S. Deva, the battery on the macbook seems to have healed itself...

Would someone please just type out the exact commands I need to put in the terminal to convert the iso to dmg. I can create the bootable usb with the etcher app….and then get the apple laptop running on ubuntu, yeah

hdiutil convert /folder/folder/file.iso -format UDRW -o /folder/folder/file.dmg

Make sure to replace /folder/folder/file.iso with the full filepath of the .iso file. To ensure correct filepath, simply drag the iso file into the terminal window at the point where you'd normally type the filepath.

Step

Open a Terminal window from the Utilities folder.

Step

Navigate to the folder containing the ISO image. For example, type cd Desktop and then press Return.

Step

Type hdiutil convert source.iso -format UDRW -o destination.img and then press Return. Replace "source" and "destination" with their actual values.

• Download the desired file

• Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)

• Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)

Note: OS X tends to put the .dmg ending on the output file automatically.

• Run diskutil list to get the current list of devices

• Insert your flash media

• Run diskutil list again and determine the device node assigned to your flash media (e.g., /dev/disk2)

• Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)

• Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).

• Using /dev/rdisk instead of /dev/disk may be faster.

• If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.

• If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive.

• Run diskutil eject /dev/diskN and remove your flash media when the command completes

• Restart your Mac and press Alt while the Mac is restarting to choose the USB-Stick

Would someone please just type out the exact hdiutil convert command I need to put in the terminal to convert an iso to dmg so I can create the bootable usb to get my apple laptop running on ubuntu.

The iso file is on my desktop, and the output file would go onto the desktop.

I assume that you all are aware of this new publicly available AI, but incase you are not, here is good vid on using it to code...

Well, my excitement with chatgpt has waned: I’ve played around with it for several days asking for terminal commands, most of which have not worked. It seems a lot of the info on the AI is unverified and has a liberal spin.

“Ever since ChatGPT hit the scene at the end of November, the artificial intelligence software program from OpenAI has shown an impressive array of capabilities - from writing computer code, poems, songs and even entire movie plots, to passing law, business, and medical exams. Unfortunately, it's also incredibly woke, and racist….For now, however, people have 'broken' ChatGPT - creating a prompt that causes it to ignore its leftist bias. In December, however, Reddit user /u/walkerspider created "DAN" - which stands for Do-Anything-Now”
