MacOS – Red box on Finder icon in Dock

findermacos

Please see this image:

I don't know what's going on with that icon, but it has been persistent for the past week. It became like that when I forced the shutdown on my Mac because it hanged up. I've just upgraded to El Capitan when it happened.

I've tried the following:

Reboot
Relaunch Finder
Quit Finder and Dock on Activity Terminal
killall Dock

Nothing worked so far.

Update:

As per user24601's suggestion, I've tried the following:

Turned on magnification. It persists on zoom. Please see image:

Tried to change position. It still persists:

I ended up reporting it as deeeeeeekun suggested. Some of the suggested workaround in the comments were also suggested to me. This is the solution they gave that worked:

1) cd getconf DARWIN_USER_CACHE_DIR

~~2) attach com.apple.dock.iconcache to radar~~

3) rm com.apple.dock.iconcache; killall Dock

I'll update the answer when they give me the reason why the redbox happened.

MacOS – What’s triggering the Finder’s CPU binges

"I wish there was a way to "get inside the Finder's head" and see what it's doing. I've tried running a sample of the Finder process in Activity Monitor, but honestly I don't know what it's doing, much less how to interpret the output."

Taking a sample in Activity Monitor is exactly that: getting inside the Finder's head to see what it's doing. While it may seem like greek, I or others here can interpret it for you. Just post it, or make it available for download or viewing (as they tend to be pretty big).

What version of OS X are you using? In OS X 10.5.x and prior, I believe multimedia content ran within the Finder itself, rather than delegating it off to an agent/helper type process, so then the CPU usage may appear higher. For example, previewing a QuickTime movie might make the 10.5.x-and-earlier Finder spike to 60% CPU, while in 10.6 it might be split to something like 10% CPU for the Finder, 30% CPU to the QTKitHelper background process.

Otherwise, I've sometimes seen the code the Finder uses to calculate the size of the contents of a folder cause temporary CPU spikes. (You'll notice something like TSomething::HFSSizerSomething in the stack trace of a sample). Usually it seems insistent on finishing its calculation even if the view you had open that warranted the calculation has since been closed.

In any case, seeing the sample should help pinpoint the issue along with knowing what context led up to the spike. It'll be easier to explain what taking a sample is doing once we have it in front of us to look at.

MacOS – How to remove the Finder icon from the Dock

There is no easy way to do this, but there is a little hack :)

Navigate to /System/Library/CoreServices/Dock.app/Contents/Resources/
Backup DockMenus.plist
Open DockMenus.plist in your favorite text editor with root access

Find section finder-running and add new sub-section

<dict>
    <key>command</key>
    <integer>1004</integer>
    <key>name</key>
    <string>REMOVE_FROM_DOCK</string>
</dict>

or just Download my version of DockMenus.plist

In plist editor file should look like this:
Open Terminal and run killall Dock.
Right click on Finder icon in Dock - Bingo!

p.s After Dock restart (manual relaunch or mac reboot) you need manually remove Finder icon from Dock
