Found a working way to refresh all my apps: using shortcuts!

I am experiencing this error on iOS 17.3. I installed the dependencies through Xcode with /Applications/Xcode.app/Contents/Developer/usr/bin/python3 -m pip install -U pymobiledevice3==2.30.0 construct==2.10.6

Happens to me on ios 17.2.1

[RockChinQ]

Same issue, running iPad OS 17.3.1 on iPad Air 5. Using AltServer on MacOS Sonoma.

[hyhcrh]

Same issue, running iPadOS 17.3 on iPad Pro 2022. Alt server is installed on macOS Ventura.

Also having this happen , blew away my homebrew and fully reinstalled brew environment according to instructions.. making sure I have OpenSSL3 and the proper versions of the pymobiledevice/construct tooling:

brew install openssl@3 python3 -m pip install pymobiledevice3==2.30.0 construct==2.10.69

Running macos 14.4.1 (23E224) on an M3 mac (arm) / iOS 17.4.1

From my mac I selected "enable JIT" for UTM.. it asks for my mac password.. works for a couple of seconds.. and then dumps this:

same here iPadOS 17.5 (21F5048f) and Alt Server on Sonoma 14.4.1 (23E224)

[psiberfunk]

@shanegillio anything on this ? Kinda game breaking..

[shinmorisawa]

bro same problem with ipad air running 17.2 with sonoma. :/

[cgorms]

Same here on 17.5 RC

[wandbrandon]

same here, 17.5

[ChristianKilduff]

facing same issue

[SpyterDev]

I was facing this same error, I'm on Mac OS 14.4, the target device was a iPad gen 9 on iOS 17.5.1 also the xcode (15.4) python version was 3.9

[tonycoco]

Just run the Python yourself.

This hardly seems like a good solution to the core problem: The app has a menu item that's just plain broken on many macs. I'm not quite sure why the issue is getting ignored.

[aabdellah]

any workaround available to use the menu item?

Thank you very much, the comment in your gist helped to resolve the issue:

If you're using AltStore you can just make sure you install the dependencies to the Python install that Xcode uses:

/Applications/Xcode.app/Contents/Developer/usr/bin/python3 -m pip install -U pymobiledevice3==2.30.0 construct==2.10.69 qh3==0.15.1

I just uploaded a video on youtube showing how to enable JIT on iOS 26 using Stik Debug. Watch it here: https://youtu.be/5F5GDwRHAec
