Some iMac and MacBook users noticed issues with Ethernet. Apple Mac security update should solve this bug and fix connectivity [here is how to fix MacBook Pro storage problems]. The problems have been reported by different users for a while so the Cupertino-based giant had to react and confirm the problem was real.
The ‘fruit’ giant even offered a support document that describes the problem and explains how to fix it. Users who installed the update offered by Apple assured that their Ethernet port refused to work. The same situation was on some iMac and MacBook models. Users couldn’t understand why the software blacklisted driver but this caused Enternet connectivity to quit working.
Fix for Security Update Macs Offered by Apple
Since a lot of users hurried to install the update brought by the iOS giant, their machines were affected. Apple pulled the update but it was too late for many users. Here is how to solve the issue right now:
Step 1. Press Option on your computer.
Step 2. Choose System Information from Apple menu.
Step 3. You need to expand software section [by the way you can chat on iPhone without internet connection].
Step 4. Choose Installations option.
