internet issues with mac OS 10.15.1

If the issue is the same as for me it would be really easy to check. Open Netbarrier the go Netbarrier > Preferences and toggle the protection switch "off". See if the problem goes away, it did for me. Since then Intego has released an update that solved the problem. I have protection toggled back on everything is working normally.

Hi @philipfromnorthridge

Best thing to do is scroll through all the answers here first - there are some really helpful guides. Certainly helped me with exactly the same problem.

Here's what I gleaned / did:-

• Checked if could connect via any browser (default browser is Safari, I also use Chrome & Firefox - mostly couldn't connect via any browser, and on those occasions when I did the connection / page load was so slow as to be painful [couple of mins for each load])
• Opened a WebPage Igonito in Chrome - still same issue
• Tried manually disabling installed "Addons / Extensions" - still same issue
• Rebooted Mac into Safe Mode (to see if any 3rd party App was interfering with connectivity) -
  • To load your Mac in Safe Mode, press and hold the Shift key while it boots. You can stop holding the Shift key when you see an Apple logo and progress bar. To leave Safe Mode, just reboot your Mac without holding the Shift key.
  • My Mac booted fine into Safe Mode and connectivity was perfect. This told me the problem was with a 3rd party App - in this case my Intego Security - but other people found a problem with other security software - it was the Firewall and fortunately Intego issued a fix within days of the macOS 10.15.1 release date.
• Updated all 3rd Party Software and try connecting again in "Normal" mode. When issues persisted, tried disabling the 3rd party software one by one to identify the culprit. Eventually identified Intego NetBarrier to be the problem and after multiple reporting an urgent fix was issued a few days later.
• Hope that helps!
• I usually wait a week or two before Installing Updates unless they comprise a Security Fix, and Google for Identified Issues & their fixes - didn't this time but will know better next time! Had to roll back to 10.15 via Time machine pending Intego Fix which wasted half a day's work o.0

Intego have told me that they are aware of the problem and are working on a fix. They'll e-mail me as soon as they (or Apple) have a fix.

The fix is actually simple. Do not install intego or other useless stuff.
