LMMS Won’t Open MAC-expert needed!

Anything that doesn't fit into other topics goes here!

I know that this isn’t really the place for complaining about bugs, but whenever I open the latest LMMS alpha as of now, it just doesn’t work. It doesn’t open.

I am using MacOS 12.7.6 (Macbook Pro, 8GB of RAM, Early 2015) and I really need help with this :(

I am out of my comfortzone, i know nothing about MAC. I have edited the caption, then we just have to hope for some MAC-user to chime in..
However there is one thing i do know, and that is that APPLE blocks free apps, and that users need to unblock apps that are not Apple-approved :

Run the following command to mark the application as safe before running:

Code: Select all

sudo xattr -d -r com.apple.quarantine /Applications/LMMS.app

Is it that?
Otherwise i can only refer to what is standards in relation to computers:
1) Shut down and remove plug from wall. Wait 2 mins and reboot.
2) Use what ever fault-tool you have in MAC and test the installation.
3) Backup, De-install, delete current install, and download the correct 1.3 for your OS:

I’ve done the quarantine thing, but the error is an unsupported OS. Apparently is requires MacOS 13.7, of which I have 12.7. I’ve tried using other DAWs like Waveform (audio was laggy) and Bandlab. (Bandlab is… Bandlab) I’ll test the 10.13 version when I have the chance.

Edit: I have tested the 10.13 version, and it still does not open. I have no idea what to do.

I will ask the only one i know uses MAC, if he have time to look at this.

Hmm... that's really odd that it just won't launch and that it says it's an unsupported OS. I wouldn't expect our nightly releases to work on Monterey, but I'd expect stable and alpha to launch just fine on Monterey. I assume you're downloading from our official website: https://lmms.io/download#mac

I can't remember if Monterey had the quarantine flags by default. I would right Click-->Open on the older OSs.

I would recommend deleting LMMS from your Applications folder and then copying in stable or alpha. Right Click --> Open I think will bypass the Gatekeeper nonsense. If that doesn't work you can try to launch it from terminal to see if there's some usable error message:

Code: Select all

/Applications/LMMS.app/Contents/MacOS/lmms --version

Sometimes the terminal will offer more info. If it just says something like "terminated", it could still be Gatekeeper and need those quarantine flags removed.

Now it just says “LMMS quit unexpectedly”.

That's odd... can you try to move your .lmmsrc.xml file and try again?

Code: Select all

mv ~/.lmmsrc.xml ~/.lmmsrc_bak.xml

it worked!!!

yippee! I just have one question. Does stuff like Sitala and Numa Player work with LMMS?

Plugin support is still very limited currently. If you can get Carla working, you may be able to load them through Carla. Sorry for the runaround, we do support some plugin formats, but currently limited on developers to get them tested and working on mac.

So… how do you get Carla on MacOS then?
