Streamline has a Mac version that can be downloaded using Safari browser only. Since the package for Mac is new, it's not yet signed with a certificate issued by Apple and requires your permission to be installed:
1. In the Finder on your Mac, locate the Streamline package. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
2. Control-click the app icon, then choose Open from the shortcut menu.
3. Click Open.
The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
Note: You can also grant an exception for a blocked app by clicking the Open Anyway button in the General pane of Security & Privacy preferences. This button is available for about an hour after you try to open the app.
To open this pane on your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click General.
