Bug: Synapse on macOS for a user using an External Home Folder

Question

Hi,I have a Mac mini M4 with an internal storage of 256 GB. To reduce my storage cost, I use an external SSD (named ExtSSD in log file) and place my User Home Folder on this external SSD. I have 2 users on my Mac:- BootUser, an useless user on internal storage: /Users/bootuser- Vallevert, my user on my external SSD: /Volumes/ExtSSD/Users/Vallevert I installed Synapse with the official installer, no problem here.When I launch Synapse on BootUser, the software works normally.But, when I launch Synapse on Vallevert, the software returns me a pop-up:“Software not readyThis app is installed for another user.Install it on your account to use it.”Button 1: “Download and Install”Button 2: “Cancel” If I reinstall it, nothing changes, same problem.I found a way to use Synapse on my main user (Vallevert). I go to “/Users/vallevert/Library/Razer/RazerAppEngine” and launch “Razer.app”. This is not a perfect way to use Synapse, but at least it works in a degraded mode. I think the problem is that the app (Razer Synapse.app) tries to load “~/Library/Razer/…”, but in this case “~” = “/Volumes/ExtSSD/Users/Vallevert/“ and Synapse thinks “~” = “/Users/vallevert/”. So it tries to find the code at the wrong path. Version: Razer Synapse 0.1.16 (1)Version 4.0.86.2507101312= latest on 2025-08-01 std-err:2025-07-31 21:24:20.621 Razer Synapse[1560:20133] 2025-07-31 9:24:20 PM: applicationDidFinishLaunching: normalStart2025-07-31 21:24:20.621 Razer Synapse[1560:20133] 2025-07-31 9:24:20 PM: checkAppEngine faild, check pkg installer2025-07-31 21:24:22.641 Razer Synapse[1560:20133] 2025-07-31 9:24:22 PM: checkAppEngine: cancel download synapse. do nothing.
