MuseScore 2.x and SIERRA (iMac OS 10.12)

• Sep 13, 2016 - 04:10

Compatible with Sierra iMac OS 10.12
I have the GM version of Sierra sitting on my desktop.
But this is my most important program (thank you)
IS IT COMPATIBLE with Sierra OS 10.12
Am I going to run into any problems?


We have not received any reports of MuseScore 2.0.3 running on Sierra. I'll report back once we have some news, good or bad.

The first time I started 2.0.3 on Sierra all was well, but now, even after a reboot, the main window is black. The interface is still responding (I can hear notes as I type letter for example), but the music score is black on black.

Setting up a new piece looks fine until get to set the key, and then that window is also black -- so anything to do with the music typesetting is failing in some way?

OK so it turns out that in Preferences->Canvas, the paper colour was set to black. I've set it to white and I'm back in business.

Not sure how that happened -- I haven't been messing with the preferences. Perhaps there's a keyboard chord I typed accidentally? Failing that it must be a bug of some sort?

Anyway, I'm happy once again. Puzzled, but happy.

For me, at least, the canvas paper colour defaults to black every time I start Musescore -- I have to reset it to black every time.

And if I don't reset the paper colour the app quits fine, but when I _do_ reset the paper colour to white, quitting Musescore gets me a "MuseScore quit unexpectedly." dialog.

I can confirm that all is good on my system. Upgraded to MacOS Sierra last night and my previously installed MuseScore (2.0.3) seems to work fine.

I have learned that “computer software is like fine wine – let it age.”

Although Apple is a little better about software quality when they are not racing to have something new to show at “Dub Dub Dee Cee” (WWDC = World-Wide Developer’s Conference), I still don’t install the initial release of any OS.   I wait a few months, then put the installation media onto a DVD or a flash-drive to do the actual install.

For me, MuseScore stopped working after upgrading to Sierra (10.12.1); it gets stuck even before opening any windows or the splash screen. Right-clicking allows me to force-quit.

Here's how it looks when run in the terminal:

$ /Applications/MuseScore\
initScoreFonts 0x7fa084630b40

Running it in lldb and Instruments reveals it's stuck getting the list of printers via Qt/printtool. The Printers preferences app gets stuck as well, indicating this is a system-wide problem. I found one thread describing a problem with a stuck Printers app on Sierra, so this could potentially affect other MuseScore users as well.

Just for the record, here's the call tree .
