Rogue Macro--Name Changed Automatically
When I type "Chuck" my computer changes it to "Mark." When I type the diminutive of Charles that rhymes with Farley, I get "the Markster." I don't type those names very often, but it sure is annoying and invasive. It happens on my iMac in Mail, TextEdit, Texty or Pages. It doesn't happen in Terminal. Where do I look for this bug?
iMac 27″, macOS 10.15
