Why convert PKG to ISO?
A flat .pkg is a XAR archive with an installer payload, a Bill of Materials, an XML manifest, and optional install scripts that Apple's Installer.app runs with elevated privileges. An ISO is a byte-for-byte copy of an optical disc in ISO 9660 or UDF format. Wrapping a .pkg inside an ISO does not change how the software installs, and no operating system expects to find a macOS installer inside a disc image in that form.

7-Zip FREE
Open the .pkg as a XAR archive in 7-Zip to read its internal files - payload, PackageInfo XML, and Bill of Materials - without executing the installer.

.pkgin an ISO does not make the software installable on any other platform; the Mac binaries inside still require macOS to run. - If you want a distributable disk image of macOS software for archival, the native macOS format is
.dmg, not ISO.
