Description
Application icons no longer appear after updating to MacOS 26.0 (25A354) Tahoe.
@viktor-kyarginskiy-staffbase @Neo-cpu761
if we copy the app to a user directory (e.g. ~), will the app icon be displayed correctly?
I copied an app to my Downloads folder, but that didn’t help:
For comparison, here's the same app in Finder:
Also, the icon in DC isn't completely blank. In fact, if you look closely, you can still see a faint silhouette. From that, I would conclude that that missing permissions are probably not the root cause.
@viktor-kyarginskiy-staffbase @Neo-cpu761
can you test it on macOS 26.1?
previously, macOS 26.0 seemed to have been found to have many minor problems.
@rich2014, It's partly fixed, but not fully. Please compare the screenshots below:
DC:
Finder:
@rich2014 I guess it is better to use NSPNGFileType and TPortableNetworkGraphic instead NSBMPFileType.
@alexx2000
- i don't guess its is the reason. as shown in the screenshot below, the Icon in /Applications is very clear (48x48). I guess it is a problem with TMenuItem/ImageList of the LCL.
I guess it is better to use NSPNGFileType and TPortableNetworkGraphic instead NSBMPFileType.
- i can open /Applications without any problem. could you please help to check the exception mentioned by @Neo-cpu761 ?
- I cannot reproduce this problem too. It is hard to say in what case an exception might arise there.
Yes.
It woks for me!
Many thanks!

@alexx2000
blur icons in "Open With" menu fixed:
- fixed in LCL/TMenuItem, and Cocoa/TCocoaWSMenuItem
- fixed in DC (13cf4d3)
@rich2014, It's not fixed.
When going to /Applications, there's still an exception: Error_new.zip
And the 'Open with' menu looks slightly different, but still not okay:

@rich2014
which model of Apple computer do you have? which monitor?
Mac mini 2023 with M2 Pro, Apple Studio Display
do you have a lower resolution display to test?
No, I haven't.
I've just set the resolution to 1280 x 720 under Settings (but still with my Studio Display), but both issues ("Open with" and exception in /Applications) still occurred.
@Neo-cpu761
on the contrary, you can try the highest resolution.
after setting, you need to restart the DC.
@Neo-cpu761
if we copy the app from /Applications to other user directory (e.g. ~), will the app icon be displayed correctly?
on the contrary, you can try the highest resolution
Same result: Wrong icons in "Open with" and exception in /Applications
if we copy the app from
/Applicationsto other user directory (e.g. ~), will the app icon be displayed correctly?
No. There will be an exception when going to that other user directory containing the app.
@rich2014, Here are the error logs from the latest snapshot:
The zip file also contains the logs generated by Apple after I had to shut down DC (pressing the Abort button actually did not close DC).

@Neo-cpu761
thx.
now we can basically determine that the exception accessing /Applications is caused by an image processing issue.
please test snapshot (12398) later.
