Mac OS Siera PyQt5 QTabWidget Issue - macos

I usually program on windows (at work) or linux (free time).
Now im doing a project for my wife, and she uses a mac.
In this project there is a QTabWidget with closeable tabs.
On windows the close icon appears properly, and as excepted, however on MAC there is no close icon.
When you click far left on the tab title it just closes unexpectedly, because you cant see a close icon, and im not 100% sure why that is.
Anyone seen this before and know of a fix?
Mac is latest Siera os (just updated)
Python 3
PyQt5 (installed with pip3)
Thanks very much in advance

This is caused by a bug which has been fixed in Qt-5.9.2 (see QTBUG-61092).
In the meantime, it should be possible to work around the issue by setting your own icon using a stylesheet. To do this, you would need to use the QTabBar::close-button selector, which is documented in the Qt Style Sheets Reference.

WSLg QtCreator broken menus and no autocompletion

I'm using WSlg with Ubuntu 18.04 on windows 11 and I've installed on it the Qt Creator IDE. Via the WSLg I can easily launch it through the start menu of windows 11.
The issue is that while coding with it I have no autocompletion (ctrl + space shows no menu). Also the right click menu after a while goes nuts and start showing in weird places of the screen until it disappears completely; same for the menus on the top bar.
I attach a picture where I show how the right click menu shows up out of the boundaries.
Anyone encountered this issue and has a solution?
So for now I have found a workaround even if it's not a proper solution.
I was using QtCreator installed via the online installer that Qt Provides. I tried using the version that comes with apt-get and I do not have those issues. Also the windowing is different because is showing the usual gray boxing of the WSLg apps; so might be related to the XWayland server architecture or something similar.
Cons of this are that the QtCreator version that comes this way is not up to date with the latest and will rely on the qt libs you have installed on your wsl (being ubuntu 18 will be qt5 and not qt6, meaning you'll not have QtCreator 8).
Also right not I'm having issue on the ClangCodeModel but I think it's a different issue.

How to verify compatibility of older Xcode on newer MacOS in terminal without opening it

When I was using MacOS 12.5.1, I found out that older version(e.g. 11.3) of Xcodes can't be opened. It's icon became a banned image and can be opened neither by double click nor 'open' cmd in terminal.
So I want to know how to verify Xcode in terminal? Use 'open' cmd is an option but if the target app is available, it will be opened which I don't expect to happen.
I found there is a "Minimum system version" in /Applications/Xcode.app/Contents/Info.plist, but no "Max system version". In my case I wanna to know which older verison of xcode is unavailable on new MacOS. Any help will be appreciated!
Use the excellent Go64 application from St. Clair Software. When you load it and scan, you can then see programs that will not work on your system clearly marked with a strike thru circle:

XCode does not open at all on Mac Mini

I bought an M1 Mac Mini recently and tried to use XCode on it, but it does not open at all.
I tried re-install it and delete ~/Library/Developer directory, it seems nothing works.
This is my first Mac device and if I give more detail about what I mean by 'does not open at all' - it does nothing even if I double click the XCode from Applications directory or the bar at the bottom that has other installed applications showing on it(sorry, I don't know how this is called).
I can see the little grey dot under the icon which means it is running somehow, but nothing comes up on the screen. Then the grey dot goes away after few minutes with nothing happening.
How do I resolve this problem?
Making sure that the application itself is in the right place would be my first approach. Did you download Xcode from the App Store?
Here’s a link to someone with the same issue asking on the Apple developers forum

Go to applications folder, right click, "get info" and then “Open using Rosetta”. Check the box.

Ruby Shoes won't start in Leopard

So I wanted to try doing some easy Ruby GUI programs using Ruby Shoes. I downloaded Shoes 3 for OS X, opened the dmg and installed it to the Applications folder. When I click on the icon in the folder, or drag a source code file to it, the icon briefly appears in the dock and bounces, and then disappears without anything running. So I can't use it. The computer I'm trying to run it on is running Leopard - is that the problem?
Have you tried building shoes 4? You might want to check it out, and check the readme. I can confirm it working on my 10.6 mac, which is about as close to leopard as you can find. Just try the directions for *nix and it should work, as far as I know.

Accessibility broken with Preview.app in OS X 10.8.4?

We have an application that integrates with different programs (among which is the Preview.app) using accessibility. We use the AXUIElementSetAttributeValue function to programmatically select some text in a PDF document using the kAXSelectedTextRangeAttribute. This used to work fine but suddenly stopped on my Mac (nothing seems to happend). My co-worker doesn't have the issue so after trying to figure out the difference I remembered that I had just updated to OS X 10.8.4 while he hasn't. I then read about this update and among the features and fixes was the following:
Improves VoiceOver compatibility with text in PDF documents
This indicates to me that they have fiddled with the area where I am having the issue. My question is now weather this is simply a bug or if it is by design. In the case of the latter, what am I supposed to use in stead?
PS. We tried also setting the selection range using the Accessibility Inspector found under Developer tools in Xcode and it works fine in 10.8.2 but not in 10.8.4, which further indicates that this might be a bug.
This is indeed a bug. I just installed the developer preview of OS X 10.8.5 and the issue has been resolved here. In the change-log it also says that some of the changes in this version regard "PDF viewing and Accessibility".
