How to add Trash to sidebar

the icon is only a "folder" with a "?" next to it

note: You can control click on that question mark folder> Remove from sidebar; and try again (below)

Easy enough to do.

From your home folder in Finder, press the three keys shift command period(.)

This will show the hidden folders including the ./Trash

Here you can drag the Trash folder to the sidebar.

Pressing that key combination will re hide hidden folders

I control-clicked the folder with the ? mark and removed it from the Sidebar.

I then shift-command-. to find the hidden files and found the Trash folder (with the icon showing as a folder). I then dragged this folder to the Sidebar and it shows up as a "document" icon (paper with the upper right corner bent down) with a "?" next to it.

You can drag anything into the sidebar.

You are not in your Favorites>home user folder. Do not drill down, Not the Macintosh HD, not the MacBook Pro

But your folder with your name in the side bar, with the icon of a house.

If you do not see your Home folder in the Sidebar, add it via Finder>Preferences>Sidebar

You can also get to your Home folder from Finder>GO>Home

After much trial and error and disabling SIP etc—

it appears the ~/.Trash folder in the High Sierra does not beautiful land in the sidebar with the Folder named Trash.

For the mean time anyway you are stuck with ? It is still functional however just not as elegant.

Sorry it used to be a no brainer.

You can however still drag it to the Finder tool bar for easy access in the Finder window if that helps.

With the hidden folders showing—

The trick here remains the same, holding the command key and drag & drop:

addendum: I see now the ? in sidebar becomes non functional once the Finder relaunches—anyway .

FWIW, I don't believe you can add the Trash to the sidebar.

Yes. Drag any other folder to the sidebar as a test and report back your results.
