• **Standalone without input signal** ( _OSX Mojave_ )
**ISSUE:** “ _I cannot use the standalone app because my signal doesn’t get into the software for some reason. It recognizes my interface, and the TEST button also sends out the signal just fine_ ".
Maybe, the app doesn’t have access to the microphone.
Please, do the following to consent for apps to use the microphone:
**1)** Select System Preferences from the Apple menu.
**2)** Click the icon labeled Security & Privacy.
**3)** Click the Privacy tab at the top.
**4)** In the left-hand column, click on either Camera or Microphone to manage app permissions. 5) Tick the boxes next to apps for which you’d like to grant access to the mic or cam.
• **PACE delayed startup** ( _Windows 7-8-10_ )
**POP-UP MESSAGE:** “ _Software Component Unavailable: A background component required for iLok License Manager seems to be unavailable. If rebooting does not fix this issue, please visit and download and run the latest License Support installer_ ”.
There seems to be another service ( _t_ _hat is slow to get started_ ) that ILM waits for. If ILM doesn’t get the needed service in time it doesn’t run and you get VST authorization errors.
To check for this problem go to **Administrative Tools/Services/** and see if " **Pace License Services**" status is " **running**". If not running then that is the problem.
The quick fix is to double click or right-click and select Properties then change " **Startup Type**" from " **Automatic**" to " **Automatic (Delayed Startup)**". This causes the PACE service to wait a while before running.
