[Interest] Will a Qt 5.x release support macOS 11?

[Ben Haller via Interest]

Hi all.  Just wondering whether there is any plan for any Qt 5.x release to 
support macOS 11.  At present, Qt 5.15 supports only through macOS 10.15 
(https://doc.qt.io/qt-5/macos.html#supported-versions), as far as I can tell, 
and my app built on macOS 10.15 apparently does not run properly on macOS 11 
(so my users inform me).  Since it looks like it will be a little while before 
a Qt 6 release is really solid (I just saw on the list that the first LTS 
release of Qt 6 is expected in September 2021, almost a year from now), it 
would be really nice if macOS 11 were added to the list of supported releases 
for 5.15.  Any chance of that?  I have users who are already on macOS 11 now; 
I’d like to have a better story for them.  Thanks for any info!

Cheers,
-B.

I am also interested in this. We may not be able to move our application to
Qt 6 in quite a while, but would be nice if we didn't have to leave macOS
users who upgrade their OS in the dust.

Our app (built with Qt 5.12) is working fine on 11. Why not get OS 11 
and test yourself?

I can't say anything for the company at this point, but at least report any 
issues you encounter in JIRA.

Builds so far seems to work, though the build process does warn about building 
for an unsupported version.

Gentlemen,
Make sure it works fine both on the Intel CPU and the new Apple M1.

In our case, there are issues on Intel CPU and crashes on M1.

Interesting. If it doesn't work on the M1, isn't that a Rosetta bug? I assume 
you haven't compiled for M1 yet given the Qt support is not released.

[coroberti]

Dear Hamish,
Yes, this is the case.

Some bugs like in webengine (chromium) have been filed,
but it could be there are others.

After getting the new HW, we'll be more knowledgeable.

Regarding the native compilation, it seems that there are good patches already
made by Tor Arne Vestbo, and the folks are compiling successfully:

https://bugreports.qt.io/browse/QTBUG-85279

Take care and the best.

FWIW no issues with my application using QtWebEngine with Qt 5.15.2,
from what I can tell.

People might need to set QT_MAC_WANTS_LAYER=1 though - for me, not doing
that caused the application to hang when opening the (QtWebEngine
default) context menu:
https://bugreports.qt.io/browse/QTBUG-87014

The respective fix didn't make it to 5.15.2:

To be useful I think we also need universal binaries for Qt, and support 
for making our own universal binaries in qmake, macdeployqt etc. I think 
there are also bugs in JIRA for those.


Unfortunately we can't build separate ARM/Intel packages and expect our 
users to know which to install.

Hi Benjamin,

Qt 5 will officially support macOS 11 in upcoming 5.15 and 5.12 patch releases, 
but should work fine already. If you encounter issues with the current releases 
(or preferably after building from git), please let us know by filing bug 
reports. Thanks!

Cheers,
Tor Arne

Correction, 5.15, not 5.12.

You can build twice and use lipo to make universal binaries after the builds 
are done.

Hi Tor Arne,

To clarify: Qt 5.15 will continue to receive patch releases under the
open source licenses until all the planned Qt 5 add-on modules are
migrated/supported in Qt 6, right?

It's not enough.

Bundled frameworks and plugins need to come as universal too.

Patch releases during the LTS part of Qt 5.15's life will be opensourced a 
year after their release. With the exception of security fixes, and the entire 
module of QtWebEngine, which will remain open throughout.

Don't know about the other postponed modules, I don't think any exceptions has 
been made for them so far. You should direct such question at Qt management.

My answer stands.

You can build Qt and your application twice, and use lipo to make universal 
binaries of everything after the builds are done.
