Why does Mosaic require this permission?
If you wish to use the Window Capture facility in Mosaic you will also need to grant access to Screen Recording, which allows Mosaic to capture the contents of a window to an image. This is the only thing Mosaic uses this permission for and if you don't use this facility in Mosaic you do not need to grant permission. If you choose not to grant permission Mosaic will silently fail when you attempt to capture a window.
How do I give Mosaic permission?
When you first start Mosaic you should be presented with the following dialog asking you to provide permission:
To grant permission you should use the following steps:
- Click Open System Preferences
- When the System Preferences window opens it will display the Screen Recording section
- Click padlock icon and enter your Admin Password to allow you to make changes
- Ensure Mosaic is ticked in the Screen Recording list
- When prompted choose to Quit Mosaic
- Re-open Mosaic from the Applications Folder
What if I don't see this dialog, or I have previously clicked "Deny"?
If you haven't seen / noticed the questions above when running Mosaic, or you saw them and clicked "Deny" before realising they are required, you can still give permission to Mosaic by following the instructions below:
- Click the Apple icon on the status menu
- Select System Preferences... from the drop down menu
- Click the Security & Privacy icon
- Click the Privacy tab
- In the list scroll to and select Screen Recording
- Mosaic should be listed one the right. Ensure the checkbox next to Mosaic is ticked, and if it is already ticked, first untick it and then retick it to force macOS to update the setting
What do I do if Mosaic is not listed in the Screen Recording preferences?
macOS only gives an app a single chance to request permissions, if it has been removed for any reason the system will not add it again automatically. In this case to add Mosaic again you would need to reset the permissions for apps, and the system will prompt you for Mosaic and other apps to provide permissions again. If you have not yet attempted to use the Window Capture functionality in Mosaic then Mosaic will not have requested permissions, if this is the case drag any window to the Window Capture extra to trigger this and you should be either prompted to provide permission, or Mosaic should appear in the Screen Recording section of the Privacy options. If Mosaic is still not displayed you can reset the system permissions to force macOS to detect Mosaic again.
To reset permissions so that Mosaic is detected again:
- Quit Mosaic if it is running
- Open Spotlight by clicking the magnifying glass icon or pressing CMD + SPACE
- Type "Terminal" and double click the Terminal application when you see it listed in Spotlight
- In the terminal window type "tccutil reset All" and press enter
- Re-open Mosaic from the Applications folder
- When Mosaic opens you should be asked for permission for Mosaic to use Input Monitoring again and Mosaic should also appear in the relevant sections of the System Preferences after it has requested permissions.
