pboard quit unexpectedly - Copy/Paste broken in High Sierra
Last week while giving a lecture to a group of engineers I got this notification that pboard quit unexpectedly. I dismissed it, but it is reappeared multiple times. Also I suddenly am unable to paste anything! 😮 This is not just an irritation.
I did a web search and it seems others have had this problem, but no lasting solutions have been found. I did an OS reinstall, which seemed to work, but the problem came back. I've tried resetting PRAM and SMC with no improvement.
HELP!!!!
I am using encrypted disk and FLASH.
I need suggestions on what to try next. I am giving lectures and teaching using this machine to large groups of professional engineers, so this is going to look bad if I cannot illustrate software due to inability to cut-n-paste.
