I've been trying to download the Mastercontroller mod on a 2023 Macbook, because the mod is downloaded as a zip file when I open the file in return I get a blank document. Any Mac users with the mod who were able to bypass this?

Right-click the .zip and select Open With > Archive Utility. That should give you a .package file, which you don't need to open or alter further.

Where you say what you get from unzipping is a blank document, do you mean that it has a file size of zero or that its icon is a generic blank document one but the file size is around 1 MB?

The latter is totally normal and the package file will still work if inserted into the correct Framework. The file icon has no impact on the performance of the package file.

Yeah the file is around 1 MB. I thought it was the Mac system could have been doing something wrong thank you!
