Pro Tools failed to launch when S1 network connected (Mac OS 10.15)

[rookiewang]

I’ve just installed two of Pro Tools with Dock/S1 systems. One of them is okay (OS 10.14), but there is a strange issue occurred in the other system (OS 10.15). When the iMac connected to the router (whatever cable or WiFi) for Eucon, I can’t launch PT (or quit) and there is only the spinning beach ball.

If I disconnect the ethernet cable, quit the Eucon, PT will launch successfully, then I connect the cable back, start up the Eucon, and everything works fine.

Here is the systems info :

System A (issue system)
iMac with OS 10.15 Catalina
UAD Apollo X16
Pro Tools 2019.12
Avid Dock x 1
Avid S1 x 2
TP-LINK TL-WR841N WiFi Router

System B (normal system)
iMac with OS 10.14 Mojave
UAD Apollo X8
Pro Tools 2019.12
Avid Dock x 1
Avid S1 x 2
TP-LINK TL-WR841N WiFi Router

I did all the same procedure to installed these two systems, there is only two different between them : interfaces and Mac OS. Does anyone know how to fix this issue? or there is a compatibility bug?

Did you set the Catalina Accessibility Security setting. There should have been a dialog box come up saying how.

Hi Eddie,

Thanks for reply.

There are 4 items setting to “allowed” :

EuControl
iLok License Manager
MC_Client
UA Mixer Engine

Here is the link of the snapshot :

(The system set to Chinese mode, I can take another snapshot in English mode if you need.)



Is that correct? still anything missing?

[EddieJones]

Thats all good. Did you try a complete uninstall of EUCON including checking the box to remove all prefs (Using the installer)

[rookiewang]

Not yet. Will try this and report the result asap.


Thanks.

Hi Eddie,

I've just uninstalled the Eucon (include the user Prefs), trash the Pro Tools preferences, re-installed the Eucon (EUCON_WorkstationUnifiedInstallMac_20_1_0_50_1067 00_.dmg) and reboot it. But the issue is still there.

Anything I can do now?

Regards,

Terence
