Roon quits at launch

[Eric_Zakim]

I am having a similar problem: Roon quits as it is opening. I receive an error message stating:

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason" ‘-[NSOpenGLContext pixelFormat]: unrecognized selector sent to instance 0x618000230120’

I have no idea what this might mean. I tried redownloading Roon, restarting, clearing out the file folders (as per Patrick’s fix above). Nothing seems to ameliorate the problem.

I am running Roon on a MacMini running OS10.9.5. The Roon website states that the OS should work, but I’m wondering whether Apple’s move to 64-bit only might be a source of the problem.

I should say that the problem surfaced suddenly a couple of weeks ago. Nothing changed on the computer. It is singularly devoted to running Roon and not used for anything else.

Any suggestions?

Hi @Eric_Zakim,

Welcome to the forum!

I am running Roon on a MacMini running OS10.9.5

MacOS 10.9 is no longer a supported MacOS version on Roon, please see:

Roon core on mac crashes at startup

Hi @Tony_Withers, I met with our development team to discuss this. It looks like there is an incompatibility with some of the new features we are using on Mac OS 10.9. The team is looking into options, but they also noted that we will likely need to be dropping support for this version in the near future to ensure that everything works properly as we have a very small number of Roon users on 10.9. If you’re able to upgrade to at least Mac OS 10.10, that would be our recommendation to get this…

If you are able to upgrade to a newer MacOS version, that should help with this issue.
