Subject: Custom Folder Icons (PNG) Disappeared and Cannot Be Re-applied in macOS Tahoe 26.4
sir:
Hello,
I am writing to report a persistent issue I’ve encountered after updating to macOS Tahoe 26.4.
The Problem:
Before the update, I had several folders with custom PNG images set as icons. Immediately after the 26.4 update, all these custom icons disappeared and reverted to the default blue folder icon.
What I’ve Tried:
1.I tried to re-apply the PNG images using the standard "Get Info" (Cmd+I) method.
2.I copied the image from Preview and tried to paste it onto the folder icon in the Info window, but it simply does not show up or revert back instantly.
3.I have tried restarting the Finder and the system, but the custom images are still not appearing.
Device Details:
OS: macOS Tahoe 26.4
Processor: 3.2 GHz 16-Core Intel Xeon W
Is this a known bug in version 26.4? If anyone has found a fix or a workaround to restore custom folder icons, please let me know.
Thank you.
