Finder Extension shows incorrect external volume sidebar icons

[shuuiran]

Workaround

This seems to be a bug in macOS. As a workaround you can disable the external volume integration of Keka's context menu in the Preferences. Available in Keka v1.2.3 and later. Still not fixed in macOS 12 Monterey, as reported by @kapitainsky in #938.

Thanks @zhouweiluan!

This is an Apple bug. Workaround is here: https://github.com/knurling/ServiceStation/issues/40#issuecomment-653660235

[aonez]

So seems that this should be fixed by Apple then... I can meanwhile add an option to disable external disk monitoring, ~so the Finder Extension will only be present at external disks that where mounted when the extension started~.

The problem appears when the external volume is assigned in the Finder Extension directoryURLs, I thought it was about NSWorkspaceDidMountNotification and such.

[aonez]

This build has the option to disable the external volumes integration: Keka-appx-volumes.7z

I've tested and this fixes the issue although renders the context menu useless outside the OS drive 😞

Hopefully Apple can fix this soon.

[aonez]

Version 1.2.3 is released now with the option to workaround this issue.

Where did you get the information about "Big Sur 11.0.1 and earlier"?

I am reproducing this issue on Big Sur 11.1 Beta (20C5048l) on a DTK. I don't yet have access to a non-beta install.

I opened a ticket for it in my Finder Sync Extension here: https://github.com/knurling/ServiceStation/issues/51

[aonez]

I meant 11.0 and 11.0.1... Haven't had the change to try 11.1 beta yet. Just changed the descriptions there's no confusion. I've already posted in your previous issue https://github.com/knurling/ServiceStation/issues/40#issuecomment-728856509. Will be creating a feedback ticket for  pointing this issue and yours.

Sadly this error reminds me of https://github.com/aonez/Keka/issues/453, an error introduced in Catalina that was fixed in Big Sur... Hopefully they fix this one in Big Sur and not in macOS 12.0 or whatever they call the new one.

@aonez I also see the same problem with Keka v1.2.9 (4434) on Catalina 10.15.7: when "Show in external volumes" or the Finder extension is enabled, disks other than the boot one are shown as a generic folder icon.

[gingerbeardman]

@lfom please read earlier comments

[aonez]

@lfom just disable external volumes in Keka - Preferences - Finder extension as stated in the main topic of this issue. Thanks!

[lfom]

Yeah, I know the workaround (as I wrote in my previous comment). I just wanted to report that it also happens in Catalina, and also in Mojave by the way, so it is not specific to BS.

[aonez]

Ah thanks @lfom! I did found this in Catalina but did not tested Mojave.

[gingerbeardman]

I can confirm it happens in Mojave.

[Apolsus]

Still happen on Big Sur 11.4 （Mac pro 2020 M1）

[J-Wick4]

Confirmed this happens on Big Sur and corrected it by turning off external volumes in settings.

[lexrus]

I wonder how does Dropbox workaround this issue...

[aonez]

@lexrus Dropbox add an icon to its folder, as I remember. Keka does not add any icon to any folder but macOS renders bad icons to external drives.

[sbarex]

On my system the bug also occurs for the normal monitored folder visible in the sidebar.

[aonez]

@sbarex this will affect all directories (folders or volumes), other than this ones (from Apple's doc):

NOTE The sidebar icons you provide will replace the default folder icons in the Finder’s sidebar for any of the root folders that your extension is monitoring. This icon does not replace the icon for any folders contained by your monitored folder. It also does not replace the icon for any system folders that you may be monitoring (for example, Documents, Desktop, Applications, and Downloads).

So you can simply add parent folder to the Finder Extension list instead of the folder you're adding to the sidebar.

An example:

• Adding /Users/sbarex/Documents/MySidebarFolder to the sidebar
• Adding /Users/sbarex/Documents/MySidebarFolder to Keka's Finder Extension list
• MySidebarFolder has a bad icon

Workaround:

• Adding /Users/sbarex/Documents/MySidebarFolder to the sidebar
• Adding /Users/sbarex/Documents to Keka's Finder Extension list
• MySidebarFolder has the correct icon
