1. Open Finder, continuously click Command+↑ several times until the you can see the disk icons without redirecting.
2. Choose the display type you want, e.g. icon (Command + 1), list (Command + 2), column (Command + 3), then press Command + J at the same time or click the pinion to open “View display options”.
3. Adjust the display size you want.
4. Open Launchpad – Others – Terminal, type “sudu find / -name .DS_Store -exec rm {} +” in and press Enter. Provide your account password if you’re prompted, then press Enter and wait.
5. When Step 4 is finished, click the apple icon in the upper left corner and select “Force Quit”.
6. In the window of Force Quit, select “Finder” and click “Restart”.
