I'm losing it. I am on the public beta for Tahoe, downloaded most current update yesterday morning, 26.4. Chrome and Firefox aren't loading, and Mac mail isn't working right. Safari seems to be totally fine. I've done all types of troubleshooting, going crazy. Anyone else had issues with this update? It's almost like the connectivity got all screwed up.
Having all types of issues with latest Tahoe version 26.4!!
Culprit. Bitdefender. Problem solved. Hopes this helps some folks.
Accept your own answer. That'll show others there's a solution to this, so they'll be more likely to view this thread and see it 😉
