Can't open Safari because its being updated
Had recent OS update on MAC and Safari will not open. All attempts to open generate the following message: " Can't open Safari because it's being updated". Restarted MAC, with no change, and last OS update in April 2019 shows complete. MAC is from 2009 and runs MAC High Sierra.
Any ideas on how to resolve?
Thanks!
iMac, macOS 10.13
