Hi, I am experiencing a persistent crash when trying to open Lexicon 1.11.14 on an officially supported Intel MacBook Pro 16-inch 2019 (i9 processor) running macOS Tahoe 26.6.2. I have confirmed that I downloaded the correct AMD64 Intel build. I have already cleared application caches, stripped the quarantine flags, and even tried forcing an ad-hoc codesign, but the app fails to launch. When running the executable directly via the Terminal, I get the following error: `dyld: Library not loaded: @rpath/Electron Framework.framework/Electron Framework` `Reason: tried: ... (slice is not valid mach-o file)` `zsh: abort` Note: I did restore user data from a Time Machine backup originating from an Apple Silicon (M4 Max) Mac onto this Intel Mac, though `printenv | grep DYLD` returns no active overrides in the terminal environment. It seems the dynamic linker under Tahoe is misidentifying the Electron framework slice inside the AMD64 build. Any assistance or a link to a previous build (like 1.11.13) to test would be greatly appreciated. Thank you! ---

I have no heard any other reports from intel macs so i think this is probably an issue on your mac only. Did you delete Lexicon, re-download, move to Applications and then start it normally? ---

I already did that and the problem persists, I never had this issue before. can you provide the previous build (like 1.11.13) to test it? thanks in advance! ---

There was no major change there so that won’t make a difference. But can you check your crash reports? `~/Library/Logs/DiagnosticReports` and mac logs? see if anything lexicon related is in there. You can upload here if you prefer: [http://upload.lexicondj.com](http://upload.lexicondj.com) Just make sure to link this thread ---

What are you using to unzip the download? Maybe that breaks it, try using the Apple utility to decompress it. The build is fine so that’s not it, something is breaking it on your machine ---
