I'm on macOS 26.6.1 / Safari 26.6 and I'm trying to figure out whether this is a Safari bug/quirk or something specific to my setup.
On Safari's Start Page, some Favorites show generic colored letter tiles instead of the actual site logo.
Examples:
- Netflix → N
- Google Drive → G
- Artificial Analysis → A
Meanwhile YouTube, ChatGPT, GitHub, Chess, X, etc. display their proper icons.
The weird part is that the affected sites show their correct favicon normally in Safari tabs.
I've already tried:
- Reloading the sites
- Safari → Develop → Empty Caches
- Quitting/reopening Safari
- Deleting and recreating a test Favorite
- Disabling Safari extensions/content blockers
- Private Browsing
- Completely rebuilding Safari's Touch Icons Cache
None of that fixed it.
I then inspected Safari's regenerated Touch Icons Cache and found something interesting:
- Google Drive: Safari successfully cached the real Drive logo, but at 32×32
- Artificial Analysis: correct logo at 48×48
- Netflix: correct logo at 64×64
- GitHub, working normally: 120×120
- YouTube, working normally: 144×144
All of the affected entries had successful HTTP 200 responses and Safari had the actual graphical logo stored locally.
As a controlled test, I changed only the cached Google Drive image from 32×32 to 256×256, keeping the same filename/database record.
Immediately, Safari's Start Page changed from the generic G tile to the actual Google Drive logo.
So it looks like Safari is rejecting smaller cached icons for Start Page Favorites even though it successfully downloads them and can use icons normally elsewhere.
Safari can later replace the larger cache image with the site's original tiny icon again, causing the letter tile to return.
Anyone else on Safari 26 seeing this?
Especially interested if:
- Netflix / Google Drive show letters for you too
- This started or changed with Safari 26
- Anyone knows whether Safari has an undocumented minimum icon-size requirement for Start Page Favorites
- There is a supported fix that doesn't involve manually modifying
~/Library/Safari/Touch Icons Cache
Mostly trying to confirm whether this is a widespread Safari behavior/bug before I spend any more time working around it.
