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 ready
This 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
