(High Sierra) Dock Icons get missing at all the time

Hi Rashdude,

I hope it's not too late:

The "Menu" mentioned is the menu you'll see when your currently active app window is Finder.

From there, click on "Go", then press "Option" on your keyboard to make the "Library" item appear.

I hope that'll help you.

Go to your applications folder, select ( do not open ) the app in question, bring up the get info box for the app ( I use command i ). Click on the icon at the top of the window and copy, click on the icon under the preview portion of the window and paste. Close the window and click on the dock icon of the app.

YES!

The LOL Game app - not the Launcher, but the actual game - is always the first app to show this erratic behaviour!

This might be a good hint for the bug-hunt. I will check this with the Riot player support.

Anyway - can you give any further details?

This did not work for me. "com.apple.dock.extra.plist" was not on the list, but "com.apple.dock.plist" was. Removed it (sent to Trash), emptied Trash and rebooted. Still had the problem (only with two programs, Malwarebytes and FinalDraft, but I use them both regularly and they looked the same.) The solution that worked was from TA_Allen (see below). Drag the icon from Applications to the desktop. Then drag it from there to the dock. Then delete the offending generic. (Thanks TA_Allen!)

Sorry TA_Allan (spelled you wrong in my previous rave of your post, my bad)

Yours is both the simplest and only solution that worked for me. I do have a weird arrow pointing to the new (proper) icon (telling me it's a copy?), but I'm much happier to immediately recognize my most-used applications. Gracias! (btw: my mac genius husband, who is totally blind and whose mantra is "for crying out loud, stupid sighted people, open your eyes" obviously couldn't care less about the generic icons. He's my go-to for most techie quirks, but for this one I had to crowd source.

Thanks to all of you for taking the time to share your fixes.

While this is entirely a possibility that the LOL game app triggers this, there should be no way any single app can completely wreck the operating system's icon cache/subsystem. I'm still hoping for Apple to provide any sort of acknowledgement of this issue.

I only had the com.apple.dock.plist file. I found it by going to Finder --> Library --> Preferences

After deleting this file, and restarting, the logos in the doc all reappeared correctly.

note: The default Apple Apps (like pages, numbers, facetime, photos, etc) will all be back in your dock, so you'll have to re-remove them and shuffle the icons around. But this process worked for me.

I would perform what many here don't like but always gives me a stable and reliable machine every time I apply an update, minor or major: deep and complete cache cleaning with (in this case) Sierra Cache Cleaner.

HTH.

Yes, the same thing starting happening on my 2015 MacBook Pro today. The dock icons for Safari, Excel, and Evernote all changed to generic icons.

I found the easiest solution is to remove the application from the dock and re-add it.

Command+Shift+G

I had the same problem after upgrading to High Sierra. I tried many of the fixes here, but the thing that ultimately fixed it was rebooting in Safe Mode.

The following will do the trick:

Run NVRAM / PRAM see this article How to reset NVRAM on your Mac - Apple Support

This worked automagically for me as well.

• Restart in Safe Mode (hold down the "s" key while restarting)
• Login to your account
• Restart normally
