+====Developer Cannot Be Verified====
+You have downloaded an application and you are sure that it is safe to run on your machine.  However when you run it, you are presented with the error ''PROGRAM cannot be opened because the developer cannot be verified.''
+The site [[https://www.lifewire.com/fix-developer-cannot-be-verified-error-5183898]] has several suggestions, that I have copied here.
+These include looking for a newer or alternate version of the application.  But I think most useful is:
+  - Open Finder
+  - Locate the app you're trying to open
+  - Control-Click (or right-click) the app
+  - Select Open
+  - Click Open\\ //this should let you open it easily in the future//

+====View hidden files and folders in Finder====
+In Finder, go to the directory, and then: ''Command-shift-.''\\
+Repeat to re-hide stuff.
+====Reset Networking====
+I found that NordVPN was not working correctly and their support said to reset the MacOS networking.  On my iMac running Catalina, I did the following to effect this:
+  * In Finder, go to /Library/Preferences/SystemConfiguration
+  * Locate these three files and rename them (like add XXX to beginning of file name -- ''preferences.plist'' to ''XXX preferences.plist'')
+    * <ff serif>com.apple.airport.preferences.plist</ff>
+    * <ff serif>NetworkInterfaces.plist</ff>
+    * <ff serif>preferences.plist</ff>
+  * Reboot the computer
+    * From apple in upper left, choose Reboot
+    * If this fails, start terminal and enter command ''sudo shutdown -r now''
+====Eject USB Stick/drive Issues====
+If you try to eject a USB drive and get message "drive wasn't ejected because one or more programs may be using it" here's some things you can try.
+Suppose drive is called DD1.\\ (You would run these commands in Terminal.)
+===What processes are using the drive?===
+''sudo fuser -u /Volumes/DD1''
+===Info about the process===
+Suppose the command above returns process ID 129.\\
+''ps -fp 129''\\
+A process with /System/Library/ in the path is a system process.  If it's in /Applications/ then it's likely a third-party app.
+===Command that started the process===
+''ps aux | grep 129''
+===Parent of the process===
+''ps -o ppid= -p 129''
+===If the process is something 'mds'===
+A process with ''mds'' in it means it's a Spotlight app.  To temporarily exclude the drive from Spotlight,\\
+''sudo mdutil -i off /Volumes/DD1''\\
+or\\
+System Settings > Spotlight > Spotlight Privacy\\
+Click + and select DD1, and add it to the list.
