I’ve had problems updating Local to the new version. I keep getting the following error
Code signature at URL file:///Users/me/Library/Caches/com.getflywheel.lightning.local.ShipIt/update.q5TBYur/Local.app/ did not pass validation: code failed to satisfy specified code requirement(s)
There was a major change in Local version 6.4.3 that required a manual update. You should be able to go to the releases page below and manually download and install the latest version!
