Update on macOS Sonoma, AltJIT, and what's next (Patreon)

Hey Everyone!

We want to give a quick update on what we’ve been working on recently. As you may be aware, iOS 17 and macOS Sonoma changed some things AltStore relies on to work properly. Thankfully, these issues are all fixable, and while we plan to have updates available soon, this is where we currently stand:

First, iOS 17 changed the “developer disk” process used by libimobiledevice to communicate with iOS devices over WiFi. AltServer uses libimobiledevice to enable JIT, which is why AltJIT is not yet supported. The good news is the open-source community has already reverse-engineered a fix, and we’ll release an update to AltServer once it’s implemented.

As for AltServer’s Mail plug-in, we’ve confirmed with Apple that Mail plug-ins will not be supported on macOS Sonoma. However, we have discovered a new workaround that we plan to release closer to Sonoma’s public release, but in the meantime you can disable SIP to continue using AltStore by following these instructions: https://twitter.com/altstoreio/status/1666173037732044801?s=20

Please be aware that disabling SIP removes important security protections and should be used with caution. We recommend waiting to update for this reason.

Because these fixes won’t be ready until later in Apple’s beta cycle, we decided to work on some much needed fixes for Delta in the meantime — primarily related to iOS 17 compatibility and Delta Sync. This should address many of the most commonly reported sync errors, and we hope to have a beta ready in the next couple weeks.

Thanks for your patience while we work on these fixes, and if you have any other questions please leave a comment!

Best,

Riley + Shane
