macOS Safari Tip – Disable Video Auto-Play


Tech Tip – Opening a web site in Safari and then having a video on the page begin to play is annoying! Of course I can mute it by clicking the speaker symbol in the tab, but the video is still playing – consuming bandwidth and processor cycles, not to mention being a distraction.

I came across a means of disabling video auto-play a week or so ago and tried it. It works perfectly! It does involved you dropping into the Terminal interface but the steps are not difficult. Here are the steps to follow:

  1. Quit Safari if it is running
  2. Open Finder >> G0 >> Utilities >> Terminal
  3. paste/type this command into your Terminal window
    defaults write IncludeInternalDebugMenu 1
  4. Hit return and wait several seconds. You will see the command prompt when it has completed
  5. Quit the Terminal
  6. Launch Safari
  7. There will be a new menu item “Debug”
  8. Choose Debug >> Media Flags >> Disallow Inline Video

Now any video embedded in a web page will no longer automatically play once the page is loaded. They can be manually played if desired.

To make the “Debug” column disappear, repeat steps 1-5 above, but enter into your Terminal window:

defaults write IncludeInternalDebugMenu 0

macOS Tip – Configure Trash to Auto Delete

It is always important to maintain as much free disk space as possible. You might not think about it but your Trash can accumulate quite a bit of disk space. Of course you can, and should, manually clean out your Trash on a periodic basis. However, we can all get absorbed in other things and before we know it, we have let the Trash grow to a significant size.

This is where setting up automatic file removal can be important. To set this up go to Finder >> Preferences >> Advanced. Check the box for “Remove items from the Trash after 30 days”. With this enabled, any files that have been moved to the Trash folder will be automatically permanently removed when they have been there 30 days. Any files less than 30 days old are left untouched.

macOS Tip – Killing a Process


Generally we can use Force Quit to kill a program, but sometimes that won’t work.

I had that case come up yesterday. A window was showing up on my screen for the program, but every time I moved the cursor over it I got the ‘spinning beachball’. The program didn’t show up in ‘Force Quit’, nor did an icon show up in the Dock for the program.

Rather than having to reboot, I was able to terminate the guilty process using Activity Monitor. I opened Utility Monitor by going to Finder ==> Go ==> Utilities ==> Utility Monitor. I scrolled down through the list of running processes until I found the one causing the problem (it actually showed that the process was not responding).


To kill the process, I clicked on it to highlight it in the list, then on the ‘X’ in the top hand corner of the Activity Monitor window. That killed the process and the errant window disappeared from my desktop.

macOS Tip – Keyboard Sequence to Open New Finder Window

I came across this useful keyboard sequence to open a new Finder window. Simply hold down the Option & Command keys, then tap the Space bar. You will get a new Finder window (Or a new tab in an existing window) each time.

I find that I need to open Finder windows often during the day and this simple process makes that just a  little easier.
