Troubleshooting & messages · Updates and installing
What does "Update couldn't be installed" mean in notifications?
Short answer: An update install was refused; the notification names why (e.g. the app isn't in Applications, or the download failed checks). Your current version keeps working — fix the cause and retry.
Storage Studio tried to install an update and something stopped it. The notification shows the actual reason — common ones are the app not running from your Applications folder, the downloaded disk image disappearing, or the download failing its genuineness check. Your current version keeps working.
Fix what the message names (for example, move Storage Studio into Applications) and try again, or download the latest version from storagestudio.us.
