MuseScore 3.6.2 on macOS - black screen on startup and when opening scores
S1 - Blocker
I'm using musescore 3.2 on MacOs 10.
It's working fine.
When I try tu upgrade to musescore 3.6.2, I get a black screen when launching, and musescore gets frozen.
It does not even open properly.
Unable to launch musescore 3.6.2 on MacOs 10.
Try reverting MuseScore to factory settings, if need be via command line (check the handbook for details)

I tryied via the command line, and I got an error message "image not found" (see attached screenshot).
And I still get a black box opening, that I eventually manage to close by clicking randomly in it.
But it pops up several time. Not very comfortable.
Those messages are probably harmless.
That black box might be the telemetry dialog, Esc should dismiss that.
The error message is abut JACK - an audio library - and my guess is that isn't related. The black screen is more likely a dialog box being displayed using OpenGL, and your display driver may not support OpenGL properly. Try updating your drivers. If there are no better versions available, it can also work sometimes to set the QT_OPENGL environment variable to something that works better. See #297956: MuscScore CRASHES on startup for more info.
Meanwhile, though, hitting Esc should close the dialog, and it won't come back unless you revert to factory settings again - it's asking for permission to send telemetry data, and Esc says "no", and that setting is remembered.
Ok. Esc works fine for the first window. And it does not appear again.
But I get another black window when I open a score. Then again, Esc works. But it happens each time I open a score.
No big deal though.
Presumably an older score (pre-3.6), so MuseScore is now displaying a dialog telling you about compatibility options. You can disable that dialog in Edit / Preferences / Import.
Realistically, there may be other elements of the UI depending on Open GL as well. So best to update your display driver or otherwise solve that problem for real.

Ok thanks for the help. Unfortunatly my MacBook Pro is too old for the latest OS. So I'll stick my my current config and use the Esc key if needed.
A few other users have reported a similar issue. I have linked the threads to this issue. Can you please provide your exact macOS version and MacBook Pro model year?
If this is not a Blocker, then what is?
Sincere apologies. Did not change it a second time. That was what the browser had when I did the Title change. You are correct, this is

No problem ;-)

It's a MacBookPro 2012. Running with MacOs 10.14.1
Thanks. That version of macOS is supported on MuseScore. According to Macs and max macOS versions your particular model supports up to 10.15, not that it should make a difference, but if one of the suggestions is to update your display driver, updating to a newer version of macOS may achieve that.
On the first screenshot, in Terminal, I see "reference error: globalStyle is not defined". That is crucial information: that means that there is an error in the QML code for those dialogs. Therefore, the dialogs won't load correctly. We would need to figure out though why "globalStyle" is undefined only on some Macs, and why it does not cause problems with the Palettes (those are also QML).

I tried but although my MacBookPro is supposed to handle an update, it was complete mess, I had to revert to my current config. It took me a full day and I lost the files I had not backed-up. So I'll stick with the black screen, no big deal.
