Keyboard Problems - Not a Blue†oø†h issue

I have a late 2013 iMac 21 inch, running 10.13.6 High Sierra. For several mon†hs, perhaps longer, I have been plagued by a poblem I †hough† was with my wireless keyboard, or the Blue†oo†h connection. As yop can see, the keyboard fails †op recognize certain characters and generates other strang ones. It some†times doesn't recognize a ke¥ s†rose at all, and all I hear is a †hump sound indicating a problem. The underline above was no† intention†ional. 


So, seeing as how I occasionally have signal problems wi†h my Blue†oo†h headphone connection, I †hough† I† was †he Blue†oo†h. I bough† a wired keyboard and I have the very same problems wi†˙ that one. Therefore, this must be a problem wi†h my iMac and no† a Blue†oo†h/keyboard connects†ion issue. 


I could use some help here. Any clear, detailed oganizd suggestions on how †ø †roubleshoo† the problem? My iMac is way pas† its warranty and I'd like tø see what I could do on my own beforeI shell ou† money for repair.


Thanks - Steven

Boot into Safe Mode (How to use safe mode on your Mac - Apple Support) by booting with the Shift key held down and check there to see if the problem persists.  Reboot normally and test again.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following; 
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts 
• Deletes font caches, kernel cache, and other system cache files

Steven,


Have you done the basics in Troubleshooting wireless mouse and keyboard issues ? Please use that as your starting point, go through all the steps (yes even if you have before) and if you still have a problem, please reset the SMC 2-3 times back to back with all USB peripherals disconnected.


Instructions for SMC Reset


If the problem persists, please let us know and we have some more steps you can try.

Do the Safe Mode restart as OT suggested and then restart normally and test. If that does not fix the problem please do the following for us.

I know you may not believe this. I tried a few of the things people suggested - not a new user - like turning settings on or off. I could find nothing at all. Both wired and wireless was the same. I am typing this on exactly the same system. as before and everything works perfectly well. I have no idea what I did to accomplish that. If you look at my first post, you can see the difference. I cannot imagine what suddenly fixed itself.
