You could create a Mac OS 9.x bootable utilities disk, from the OS installation on the hard drive - if you know what you're doing. You'd need a third-party software like 'Toast' to recognize the third-party CD-R/RW burner and write the bootable disk. You'd need to determine which assortment of System Folder files were necessary to copy, to create the abbreviated System Folder on the bootable CD. You can burn data CDs with USB 1.1, but you'll be limited to 4x burn speed - which is slow, but not intolerable. If you can borrow or buy an older USB CD-R/RW drive that's backward-compatible with your iMac's USB 1.1 bus speed, you could accomplish this. The alternative is to check eBay for Norton SystemWorks 1.0 for Macs, which shouldn't be expensive. The disk is bootable and would enable you to run DiskDoctor, and then Optimize the disk. This consolidates/moves all data on the drive and arranges it by file type, and then leaves contiguous free space at the end. You can select to wipe the free space with a security wipe, to remove all traces of your personal data. The average user won't be able to recover it. Otherwise, you could check eBay for a Mac OS (retail) universal installer disk for OS 8.1, 8.5, or 9.x and just reload the software to a newly-reformatted hard drive. If you want to sell it, you may have to spend a little $$ to do so. Considering the negligible value of a working 233 MHz iMac now, you'll likely not make a profit. I suppose that's why so many just remove the hard drive and e-Cycle old computers.

It does not matter whether you use macOS or Windows 10. It's just a matter of time until your device will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it.

This is one of the main reasons you should consider making a macOS bootable USB when your device is working properly. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) aren't working when you need them the most, then you can use a PC to rescue your Apple device. You can use a Windows 10, Windows 8.1, or Windows 7 device to quickly create a USB bootable installation media to reinstall macOS Catalina or Big Sur on your Mac.

In this guide, you'll learn the steps to create a macOS Catalina bootable USB installation on Windows 10, which you can use to reinstall or upgrade the Apple OS.

Requirements

Before proceeding, you'll need the following:

• Broken Mac computer running macOS (version 10.12, 11, or later).
• A trial copy of the TransMac software.
• One high-quality USB flash drive with 16GB of storage.
• Copy of macOS (DMG file).

Create macOS bootable USB installation media

To create a bootable USB drive with macOS, use these steps:

1. Download and install TransMac on the Windows 10 device.

   Quick note: This is a paid software, but it gives you a 15-day trial, which is more than enough time. (If this works for you and you want to support the developer, you can purchase the full version.)

2. Connect the USB flash drive. (If you have any data on the flash drive, remember to make a backup, as everything on it will be erased.)

3. Right-click the TransMac app and select the Run as administrator option.

4. Click the Run button. (If you're using the trial version, wait 15 seconds.)

5. Right-click the USB flash drive, select the Format Disk for Mac option from the left navigation pane.

   Quick note: You want to do this before creating the bootable media because there is a good chance that the drive was formatted using a Windows device. If this is the case, the chances are that it's using an MBR partition, and the USB drive needs a GPT partition to work on a Mac.

6. Click the Yes button to format the drive on the warning message.

7. Confirm a name for the drive. For example, 'macOS bootable USB.'

8. Click the OK button.

9. Click the Yes button.

10. Click the OK button. Kms activator for mac office 2016.

11. Right-click the USB flash drive and select the Restore with Disk Image option from the left navigation pane.

12. Click the Yes button to confirm the erase of the USB flash drive data. Install mac from usb.

13. Click the browse button on the right.

14. Select the .dmg file with the macOS installation files.

15. Click the Open button.

16. Click the OK button.

17. Click the Yes button.

Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, or higher.

Create a GPT partition on USB flash drive

If the USB flash drive is not working with TransMac, it could still be a partition problem. In this case, you may need to redo the entire process again. However, this time you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions.
