BUT running from Dock or just click ok 'restart' calibre goes to memory leak.

You've wrote in one of your first messages

What I’ve tried:
...
- Installing with the installer and not brew

I'm using the .dmg from the calibre download page and simply copy the app to my Application folder.

It cant be that as I said device scanning happens in its own thread so even if it paused it wouldnt cause slow startup

So it must be something else that makes "Constructing main UI..." to pause after loading the plugin libusb.so...

Update. Direct call stopped working.

I tried to debug I run:
/Applications/calibre.app/Contents/MacOS/calibre-debug -g
then
sample 11568 -file ~/Desktop/calibre_hang_sample.txt

results:

at the moment of snapshot: Physical footprint: 56.6G after only ~17 seconds.

The main thread is stuck deep inside the Qt event loop (QEventLoop::exec → NSApplication run).

QAbstractItemView::dataChanged
→ sipQTableView::dataChanged
→ massive activity in libqcocoa.dylib (macOS Cocoa backend)

QAbstractItemModel::dataChanged
QAbstractItemView::dataChanged
sipQTableView::dataChanged
sipQListView::dataChanged
libqcocoa.dylib
QAccessible::updateAccessibility
QAccessible::queryAccessibleInterface
QAccessibleCache::idForObject

It is doing thousands of Objective-C object allocations (_objc_rootAllocWithZone, NSMutableArray insertions, malloc_type_calloc, etc.) every millisecond.

Is it a Qt/macOS accessibility bridge bug?

So book list is going crazy if i'm understand correclty.

workaround with script stopped working.

i've debugged
/Applications/calibre.app/Contents/MacOS/calibre-debug -g
sample 12345 -file ~/Desktop/calibre_hang_sample.txt

TLDR: calibre 9.8 / PyQt6 / Qt Cocoa backend on macOS 26.4.1 explodes while handling dataChanged updates for a large calibre model.

---

Physical footprint: 86.0G after few seconds ( it can go beyond 100–150 GB before os kills it )

The sample shows exactly where Calibre is dying:The main thread is stuck deep inside the Qt event loop (QEventLoop::exec → NSApplication run).

QAbstractItemView::dataChanged
→ sipQTableView::dataChanged
→ massive activity in libqcocoa.dylib (macOS Cocoa backend)

It is doing thousands of Objective-C object allocations (_objc_rootAllocWithZone, NSMutableArray insertions, malloc_type_calloc, etc.) every millisecond.

this is book list (QTableView ) table going crazy trying to refresh/redraw tens of thousands of rows + thumbnails at once.?

setting QT_ACCESSIBILITY=0 didn't help

Key stack trace pattern
The hot path is consistently in Qt/PyQt model/view update handling and the macOS Cocoa platform layer, especially around dataChanged handling for table/list views.
Representative stack path:
QApplication::notify
PyQtSlotProxy::qt_metacall
pyqtBoundSignal_emit
emit_QAbstractItemModel_dataChanged
QAbstractItemModel::dataChanged
sipQTableView::dataChanged
QAbstractItemView::dataChanged
libqcocoa.dylib
_objc_rootAllocWithZone
_xzm_xzone_thread_cache_fill_and_malloc
The second sample, even with QT_ACCESSIBILITY=0, still shows the same model/view/Cocoa allocation pattern:
emit_QAbstractItemModel_dataChanged
QAbstractItemModel::dataChanged
sipQTableView::dataChanged
QAbstractItemView::dataChanged
libqcocoa.dylib
_objc_rootAllocWithZone
_xzm_xzone_thread_cache_fill_and_malloc
There are also accessibility-related frames present in the sampled call graph:
QAccessible::updateAccessibility
QAccessibleEvent::accessibleInterface
QAccessible::queryAccessibleInterface
QAccessibleCache::idForObject

It is definitely accessibility related. Check the accesibility settings on your machine, Qt does not play nice with macOS accessibility.

serrnovik · 05-05-2026, 06:03 AM

Thank you for your help. That was a very useful hint.

I don't have anything special in accessibility settings. Option + ⌘ + F5 (Accessibility Shortcuts panel)- > nothing selected.

So i went to disable third-party apps using Accessibility one by one.

�� After turning off alt-tab.app calibre starts in 2 seconds.

So i'll just disable alt-tab for now.

Very not obvious issue.

KevinH · 05-05-2026, 05:34 PM

Given tab functionality to shift window focus is built into Qt and given you can enable it in MacOS with no alt-tab.app accessibility app needed, using a alt-tab.app with any Qt app on MacOS is probably not a good idea at all.

See MacOS System Settings -> Keyboard, then turn on "Keyboard Navigation".

This works quite well with all Apps (Qt or not) I have tested so far on my MacOS machine.

I've installed macOS Tahoe 26.5 and a driver update for my cyberJack Chip card reader and now calibre starts without any delays...

KevinH Sigil Developer Posts: 9,669 Karma: 6774048 Join Date: Nov 2009 Device: many	Given tab functionality to shift window focus is built into Qt and given you can enable it in MacOS with no alt-tab.app accessibility app needed, using a alt-tab.app with any Qt app on MacOS is probably not a good idea at all. See MacOS System Settings -> Keyboard, then turn on "Keyboard Navigation". This works quite well with all Apps (Qt or not) I have tested so far on my MacOS machine.

serrnovik Member Posts: 11 Karma: 57290 Join Date: Oct 2025 Device: ipad	workaround with script stopped working. i've debugged /Applications/calibre.app/Contents/MacOS/calibre-debug -g sample 12345 -file ~/Desktop/calibre_hang_sample.txt TLDR: calibre 9.8 / PyQt6 / Qt Cocoa backend on macOS 26.4.1 explodes while handling dataChanged updates for a large calibre model. --- Physical footprint: 86.0G after few seconds ( it can go beyond 100–150 GB before os kills it ) The sample shows exactly where Calibre is dying:The main thread is stuck deep inside the Qt event loop (QEventLoop::exec → NSApplication run). QAbstractItemView::dataChanged → sipQTableView::dataChanged → massive activity in libqcocoa.dylib (macOS Cocoa backend) It is doing thousands of Objective-C object allocations (_objc_rootAllocWithZone, NSMutableArray insertions, malloc_type_calloc, etc.) every millisecond. this is book list (QTableView ) table going crazy trying to refresh/redraw tens of thousands of rows + thumbnails at once.? setting QT_ACCESSIBILITY=0 didn't help full logs: https://gofile.me/7yvch/j8iSF5e8S https://gofile.me/7yvch/teUqQvy0x Key stack trace pattern The hot path is consistently in Qt/PyQt model/view update handling and the macOS Cocoa platform layer, especially around dataChanged handling for table/list views. Representative stack path: QApplication::notify PyQtSlotProxy::qt_metacall pyqtBoundSignal_emit emit_QAbstractItemModel_dataChanged QAbstractItemModel::dataChanged sipQTableView::dataChanged QAbstractItemView::dataChanged libqcocoa.dylib _objc_rootAllocWithZone _xzm_xzone_thread_cache_fill_and_malloc The second sample, even with QT_ACCESSIBILITY=0, still shows the same model/view/Cocoa allocation pattern: emit_QAbstractItemModel_dataChanged QAbstractItemModel::dataChanged sipQTableView::dataChanged QAbstractItemView::dataChanged libqcocoa.dylib _objc_rootAllocWithZone _xzm_xzone_thread_cache_fill_and_malloc There are also accessibility-related frames present in the sampled call graph: QAccessible::updateAccessibility QAccessibleEvent::accessibleInterface QAccessible::queryAccessibleInterface QAccessibleCache::idForObject

kovidgoyal creator of calibre Posts: 46,254 Karma: 29630732 Join Date: Oct 2006 Location: Mumbai, India Device: Various	It is definitely accessibility related. Check the accesibility settings on your machine, Qt does not play nice with macOS accessibility.

serrnovik Member Posts: 11 Karma: 57290 Join Date: Oct 2025 Device: ipad	Thank you for your help. That was a very useful hint. I don't have anything special in accessibility settings. Option + ⌘ + F5 (Accessibility Shortcuts panel)- > nothing selected. So i went to disable third-party apps using Accessibility one by one. �� After turning off alt-tab.app calibre starts in 2 seconds. So i'll just disable alt-tab for now. Very not obvious issue.
