Valid Download of Mac OS X 10.4.11
After much hesitation, two or so years ago I updated to OS Catalina. Then I learned that a critical app for me, Hyperstudio, would not run on Catalina. I contacted the company but they did not aa Catalina-compatible version of Hyperstudio. To date, no compatible version of Hyperstudio from them.
I can create a partition on my Mac (iMac (Retina 5K, 27-inch, 2017) to host Mac OS X 10.4.11 (Mojave) to host the software. I have been all over the Apple website, buy every download of Mojave will not open on my computer. What can I do.
Thanks.
iMac 27″ 5K, macOS 10.15
