Can’t open ProjectLibre on M1 Mac

ProjectLibre 1.9.8 runs on Linux, Windows and macOS. 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.

“You must allow the installation under Security/Settings as it does not come from the Apple website.” This no longer works. The option is no longer available in the latest MacOS 15.5. Is there another option?

i also fail to run 1.9.8. it seems to be install but failed to run. Now running 1.9.3, and will love to get the latest version 1.9.8. Any workaround?

Hey
Same here. Got a mac M2 chip and it wont open. Any ideas? Thank u

I’m on an M4 Mac and can’t open ProjectLibre – the app is in my Applications folder but when I double-click nothing happens. Dying to use the desktop version but so far no luck!

Same for me, but was easy to fix: I had to install “harfbuzz”.
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

I’m having the same issue. Have a M4 MacBook Air and downloaded latest version, but unable to open or run program. Solution needed please.

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

Had issues with getting Project Libre to run on my Mac, like everything would download fine but nothing would happen when I tried to open. A lot of suggestions about changing security preferences but these are all out of date as you can no longer change these, but also these are irrelevant to what needs to happen.

You need to download Homebrew in order for it to run on your Mac. I am not super technical but I tried to open Project libre in Terminal, then pasted the code and error into Chat GPT and had it analyze what to do. It provided me with the entire code I needed to run to install Homebrew and then once I downloaded it fully, I reopened Project Libre and it worked.

If you are able to download Project Libre fine, and it just won’t open or do anything, this is what you need to do.

Hello it works after several test :
1 install Homebrew in console
2 copypast code

brew install harfbuzz
brew install –cask projectlibre

3 install Projectlibre

Hola buenas , en mi ordenador Mac Book pro de 2021 tampoco me deja abrirlo después de instalarlo , si alguien sabe como solucionarlo , y explicarme los pasos para solucionarlo

Error message needed please

Here’s a (hopefully) more complete description of the error that I (and I suspect others) are experiencing:

Hardware: Apple M2
OS: Mac OS 14.6.1 (Sonoma)

Steps to reproduce, starting with a machine that does not have ProjectLibre installed but that *does* have homebrew installed.

$ brew install harfbuzz
  ...
$ brew install --cask projectlibre
  ...

Please let me know if I can provide additional information

Hi @all
any news? I have the exact same issue on my Mac with Tahoe 26.2

Many thanks for any help.
Kind regards
Nic

after installing homebrew and harfbuzz it worked for me too.
Dont forget to add the path. Follow exact the instruction and read carefully your message after installing homebrew
many thanks

Hey folks, I’ve got Homebrew installed and installed harfbuzz.

However, while trying to install ProjectLibre(1.9.8), I get these errors:

$ brew install –cask projectlibre

Hello same here, I downloaded and it doesnt open…is there any fix ?

I first installed projectlibre using brew install --cask projectlibre and after read the post 4035 I installed harfbuzz using brew install harfbuzz. Then I just opened the projectlibre app from spotlight and it worked.
