System Extension Block Message with High Sierra 10.13
when installing mac software downloaded from bc
When installing software downloaded from Boston College for the first time on a Mac with High Sierra 10.13 or higher, you will get an extension block alert after installation (see Figure 1 with example from Sophos & Figure 2 with an example from Cisco).
If you get an alert like one of these (see Figure 1 & 2), do the following:
- Within 30 minutes after installing the software, open System Preferences.
- Double-click Security & Privacy.
- On the General tab, click Allow next to "System software from developer 'software_name' was blocked from loading." (see Figure 3 with example from Sophos)
Note: You may need to click the lock on the bottom left before you can make these changes.
