Finder Sidebar icons for SSDs shows wrong icon

I have the same Issue but with the Icon of the Supercharge Extension, which is also a File Provider Extension.

As soon as I deactivate the extension, the icon is displayed correctly again.

So to me, it looks like this is a bug, because MacOS Tahoe appears to be incorrectly using the icon of an installed extension for all mounts.

I discovered this was due to the sync.com app extension taking over the finder sidebar icons. The simplest solution was to go to system settings/Login Items & Extensions and disable Sync. Others may want to see if this solves the problem for themselves. Clearly this is an issue that devides the responsibility between Apple and the App developers, but I would put the onus of that responsibility on Apple for allowing an extension to just take over all the sidebar icons.

It appears to be a bug in Tahoe that affects apps that have Finder Extensions. Try disabling the Finder extension for the app that's showing up incorrectly under System Settings -> Login Items & Extensions

Some discussion here:

https://community.folivora.ai/t/tahoe-update-some-finder-icons-changed-into-btt-icon/45192

Apparently solved by uninstalling PureRaw and then reinstalling.

Odd, they show as drives for me.

Try relaunching Finder – press and hold the Option key then secondary-click (control-click, two-finger click) on the Finder icon in the Dock, then select Relaunch (bottom option).

For what it’s worth:

“Thank you for reporting the issue where external drive icons in the Finder sidebar are replaced by DxO PureRAW icons after installing macOS Tahoe. The fix is already scheduled and will be included in the update planned for December 9.”

In my case BetterTouchTool is the app that shows up in the Finder sidebar in place of the correct icons.

Simply moving that app to the trash and reopening the Finder window seems to fix it temporarily.

Moving the app back to the Applications directory brings the incorrect icon back.

Deleting the app and re-installing it also brings it right back.

I've also tried deleting the Finder directory in my home Library/Caches folder and restarting Finder. This also doesn't fix it.

The search continues...

Yup, but for me it's BetterTouchTool:

seems like it's a bug in the Finder grabbing some random app icon instead of the volume's own icon. restarting finder, rebooting the Mac, removing and re-adding the icon doesn't seem to help.

I've been reading this thread. Earlier I saw that the icon problem affected different applications, so I concluded the problem was with the OS. I was wrong about that. It appears that each app causing the problem will need its own fix. There are definitely change in the way Tahoe handles icons. (for example, I had to clear the icon cache -- aliases weren't working right.)

Do we assume this quote came from DxO PureRAW...?

I see no reference, no link

is this personal communication with DxO PureRAW you do not say.

But you have to decline the finder extension during the install process.

My fault, I had thought Hookmark was a typo (Bookmark), not a the correct spelling of an extension that seemingly needs to be updated for Tahoe compatibility.
