This is a five star app and a 5 star company if you need to respond to frequent questions. The complaints arrive from the fact that the company needs to walk a tightrope to make the product work. Apple is concerned with our security (yay). Texfexpander is trying to make us more efficient. (yay). I have had this app on all my computers and iphones for years. It has saved me countless hours. Just happened to ask customer service a question yesterday about my new Macbook and they responded within a few hours. The keyboard does need full access, but all of them do. This company has a long track record of mac developement. I use it with no concerns. And when it crashes and I need to revert to the standard keyboard it just reminds me how much work it saves me when it is running. The only option is to use the built in keyboard shortcuts, but before you do that make sure and check the apple discussion boards. Some people like me, have had apple shortcuts for years that have synching problems. I have never had a problem with correct textexpander syncing.
