Aerial used to automatically update (since version 1.5.0) using the Sparkle framework.
With the introduction of macOS 10.15 (Catalina), things changed for screen savers and Aerial was no longer able to update itself because of the new security restrictions introduced with sandboxing. A temporary workaround was put in place in version 1.8.0 where you could get notified of a new version but not automatically install.
While this worked most of the time, for some users, the update check caused the
ScreenSaverEngineto lose the keyboard/mouse focus, and pressing a key would no longer let you exit the screen saver (pressing
cmd-alt-shift-esccould be used as a workaround). This issue seem to trigger a lot more often in macOS 11 (Big Sur). Due to this, Sparkle was removed from Aerial starting in version 2.0.0 and native support was added using Aerial Companion.
During your first launch you will be able to set up Aerial Companion to keep you up to date the way that you want. Choose whether it checks for an update hourly, daily, weekly, or only when you want to update manually. Run the companion app in the foreground from your menubar, or in the background without any effort from you. Stay up to date with either stable releases or beta updates.
In this repository, I store a manifest file that contains the version number of the latest release, and also the sha256 of the releases. This is generated after Aerial gets notarized for distribution and before I upload a new version on Aerial's releases page.
Periodically, Aerial Companion checks the manifest to see if a new version was released. When you decide to perform an update, the following happens - Aerial Companion uses the version number from the manifest to infer the download link from Aerial's repository (the download links are always of the same format, so version
1.9.2will be available at
https://github.com/JohnCoates/Aerial/releases/download/v1.9.2/Aerial.saver.zip) - The zip file is downloaded to
~/Library/Application Support/AerialUpdater/- The sha256 of the file is computed, and compared to the one from the manifest - The zip is unzipped in place, looking for
