Privacy errors when accessing many websites only occurring for MacBooks on company network
We have a group of five macbooks on a network that is mostly windows. For more than a week, we have been having issues with privacy errors - net::ERR_CERT_AUTHORITY_INVALID on sites we've been using for years. And this error is only occuring on macbooks - pcs are not having the issue at all. Our IT group has been unhelpful in finding a solution, they've been whitelisting the sites one at a time and it's an imperfect solution. We use a lot of web-based tools and Adobe products. Adobe is unable to verify our subscriptions, so it causes interuptions in our ability to use Adobe apps installed on our macbooks.
This issue only occurs when we are connected to the company network - when I'm logged in on home internet, I don't have the issue - even if I'm VPN connected to the company.
Any ideas?
