After the Creative Cloud desktop app updated to **6.11.0.479** (2026-10-15), every install of our hybrid UXP plugin (`.ccx` with a `.uxpaddon`) on macOS 26.6 comes out broken in one of two ways: - **A.** `PluginsInfo/v1/premierepro.json` records the plugin as `$systemPlugins/root/External/_` — a folder that does not exist — so Premiere logs _Failed to open the manifest.json_ and shows no plugin, although the files were copied correctly under `Plugins//External/`. - **B.** The installed tree is `root:wheel` **744**. The `.uxpaddon` still loads (dlopen only reads), so the panel starts, but every bundled helper executable fails with _permission denied_ when the plugin spawns it. The same `.ccx` installed fine 20 times before the update (755, record under ``). The logs show why: the ExMan elevate server no longer launches (`launchElevateServer failed`) and Creative Cloud falls back to `launchAIviaAUS`, an installer worker that runs with **root’s own environment** (uid 0 in the system `EMCL.log`) instead of impersonating the requesting user. Same CC version on **Windows is not affected** : there the UAC worker keeps the user’s name and inherited ACLs. Workarounds: `chmod -R a+rX` + fixing the record by hand; or installing into the **user tree** (`$localPlugins/External/…`), where the hybrid plugin loads with no elevation at all — verified. Questions for Adobe: should the AUS-launched installer impersonate the requesting user (HOME, umask) as before? Is there a supported user-level install target for hybrid `.ccx` plugins? ---

@birdofscript Thanks for reporting the issue. I’m trying to reproduce the issue at my end. To help with the investigation, could you please share the logs collected using the **[Adobe Log Collector tool](https://helpx.adobe.com/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-log-collector-tool.html)** and send them to neearora at adobe dot com. Additionally, please share your **email ID** _via DM,_ so that we can schedule a session to look into the exact steps to reproduce the issue. This will help us gather the necessary details and investigate the issue further. ---

Thanks for looking into it. I have emailed you the Adobe Log Collector output from the affected Mac, two Premiere UXP logs the collector skipped (they hold the “Failed to open the manifest.json … Plugins/root/External” lines) and the full technical report with the verbatim log excerpts, with Bruce in copy. I can reproduce it on demand, so a screen recording of the exact steps is available if useful; my address is in that email for scheduling.
