Trying to install SX3 on Mac to convert old files but get "The disk you attached was not readable"

I urgently need to access my old .ARR and .ALL files. I am using Cubase 11 with a license on MacOS Sonoma and I downloaded the Cubase SX, but the Mac is not reading it. I get the following message The disk you attached was not readable by this computer.
Can someone please help?
Thank you

You’re trying to run Cubase SX in 2024? Was there even an Intel version of Cubase SX on the Mac? You might need to find a 25-year old computer.

a Windows can machine can install and run SX fwiw.

Hi,

No, there wasn’t. Cubase SX was PowerPC only. The first Mac Intel sorted version was Cubase 4.

In that case, he might be able to find a Mac capable of running Rosetta, but even that would have to be an ancient computer. Steve’s right, he might be able to open it with a windows version of Cubase SX.
