Previously authorized software from Apple & recognized developers. Dragged icon to Applications & MacOS dialog box noted that file was downloaded but had no malware. Clicked open and now have PL icon in apps but won’t open. Installed Java v11.jdk but still won’t open. Have any suggestions?

Thanks,
Chris

However, on macOS it is only on Apple Silicon. It does not run on macOS using x86 chips. There is a workaround if needed but the easiest is to go to Sourceforge.net and ProjectLibre download files and download the 1.9.3 version. That will run on the x86 macOS.

You will need to go to Security/Preferences and “allow” installation since it is not coming from the Apple site. We do have a further workaround if for some reason you are having an issue on Mac and it ‘is’ on an M chip.

The option is no longer available in the latest MacOS 15.5. Is there another option?

On Mac, never did not get dialog box allowing me to authorize application to run. On Linux I received warning that Project Libre was not compiled for ARM processor. I finally was able to get 1.9,3 to run on Mac, but would prefer to use most recent version.

Is there another workaround for Mac or Linux?

Dying to use the desktop version but so far no luck!

If you use brew:

brew install harfbuzz
brew install --cask projectlibre

Without brew, you may try your luck here: https://github.com/harfbuzz/harfbuzz

(You may want to start ProjectLibre in a terminal and see to error message)
> /Applications/ProjectLibre.app/Contents/MacOS/ProjectLibre

When you start ProjectLibre in a terminal (not just click the icon), what is the error message?
