That said, if you are a tech enthusiast or a virtualization user (e.g., running macOS on VMware or VirtualBox on Windows/Linux), here is a practical review based on the converted ISO version of macOS High Sierra 10.13.6.

How to Get a Safe ISO (Self-Create)

If you still need a legitimate ISO for virtualization:

Download “Install macOS High Sierra” from Apple’s support site (if you purchased it before).
Use Terminal commands to create a bootable .cdr image, then rename to .iso.
No third-party download required.

Troubleshooting & Limitations

VMware/VirtualBox graphics acceleration – Limited; install VMware Tools or VirtualBox Guest Additions.
APFS boot issues on real HDDs – 10.13.6 is stable, but older firmware may need a firmware update.
ISO not booting – Ensure ISO is hybrid (UEFI+BIOS). Use createinstallmedia method for best results.
App Store no longer offers High Sierra – Apple removed it; obtain from Purchases tab or a trusted backup.

Part 8: Step-by-Step – Installing High Sierra 10.13.6 from USB (No ISO Required)

For Mac users who have the official .app:

Use the createinstallmedia command (Part 3 above).
Plug USB into target Mac.
Restart and hold Option key.
Choose “Install macOS High Sierra” from the boot picker.
If the Mac has an unsupported drive (e.g., NVMe on older MacBook Pro), you may need third-party patchers (like dosdude1’s High Sierra Patcher) – but that’s another article.

For VM users with your own ISO (created in Part 4):

In VMware, create a new VM → Guest OS: Apple macOS 10.13.
Mount the ISO as DVD drive.
Boot and install normally.
