When a Mac Update Leaves Things Broken: Troubleshooting After a macOS Update
A recent macOS update can sometimes leave your Mac feeling more like a headache than a help. Here’s how to troubleshoot common issues like printer failures, mail glitches, and login problems without resorting to a clean install.

After a macOS update, it's not uncommon to find yourself facing unexpected issues. From printers that refuse to cooperate to email applications that won’t send, these glitches can disrupt your daily routine. At The Nerd Network, we often receive calls for help after updates, and we’re here to walk you through some practical steps you can take before booking a visit.
Troubleshooting Printer Problems
If your printer suddenly goes silent after an update, the first step is to check the connection. Ensure that it's plugged in and connected to the Wi-Fi network. Sometimes, a simple restart of the printer can resolve the issue. If your Mac no longer recognizes the printer, go to System Preferences > Printers & Scanners. Remove the printer and add it again. This might fix any communication issues caused by the update.
If these steps don’t work, you might need to visit the printer manufacturer's website to download the latest drivers. This is especially important if you have an older printer that might not have automatically updated drivers compatible with the new macOS.
Addressing Mail Application Glitches
Another common issue post-update is the Mail app acting up. If you find it crashing or not sending emails, start by quitting the app completely and reopening it. If problems persist, navigate to Mail > Preferences > Accounts and check that your account settings are correct. Sometimes, re-entering your password can do the trick.
If you’re still having trouble, consider rebuilding your mailbox. Go to Mailbox > Rebuild while in your inbox. This can help clear out any minor corruption that might have occurred during the update.
Fixing Login Issues
If you're having trouble logging in after an update, it could be related to your user account or password settings. Start by ensuring that Caps Lock is off and that you're entering your password correctly. If you’ve forgotten your password, you can reset it by clicking the question mark next to the password field on the login screen.
If the login issue continues, boot your Mac into Safe Mode. To do this, restart your Mac and hold the Shift key until you see the login window. Safe Mode disables unnecessary files and can help you troubleshoot further.

If you’ve tried these troubleshooting steps and things are still not working, it may be time to get some expert assistance. Sometimes, issues can be more complex and require hands-on attention. That’s where The Nerd Network comes in. We’ll come to your kitchen table or workspace, assess the situation, and get everything back up and running without the need for a clean install.
