internet issues with mac OS 10.15.1

I upgraded two iMacs here, both have the same issue. Not only the internet but local connections as well. I cannot connect to the admin page on either my router or NAS units. I didn't update my laptop so I'm able to access the internet with it.

Upgraded to 10.15.1, wish I hadn't bothered. 2019 iMac won't cleanly shut down/restart - hangs and then eventually reports a problem. Browsing via Safari extremely slow.

Worse than Microsoft, and that's saying something.

Hi Luis, thanks for the quick reply. When you say uninstall Intego do you mean permanently? I don't want to be without a virus checker (I've know uninstalled all 32 bit apps I could find, including Toast. It hasn't helped)

I'm having the same issues here having upgraded my 2012 MBP 13" which was running Mojave quite happily.

Strangely Safari (& Firefox/Chrome) loads the Apple.com site at 'normal' speed, definitely doesn't like loading any others at the same speed especially anything like Gmail??!

It doesn't work in safe mode on my computer. After a reboot it works briefly. Almost like a memory buffer, or cache is filling up and not clearing. Once full all incoming data stops. I tried safe boot, disconnecting all my perpetuals The results are all the same. I brief connection followed by a slowdown of incoming data. Then everything stops. Its a real pain, but I could boot off my external HD, and reinstall 10.15 a process I really don't want to have to start. I'll wait until Apple has something to say.

The resolution to this issue has absolutely nothing to do with 3rd party software to blame. Its obvious we were all working 100% prior to the upgrade. The culprit here is captain obvious...the 10.15.1 upgrade. Don't waste your time removing apps etc.........this problem will kick up some serious dust as it affects one of the earths most important resources......the internet and access to it. Take internet away from any human and sh1ts gunna hit the fan. I bet Apple is already onto 10.15.2 in the next 24 hours.

Its a real pain in the *** though.

Hello, I have the same problem of not being able to connect to the internet after the update to 10.15.1. I have been using Intego's Virus Barrier & Net barrier for some time and Luis's comment may have some merit.

I turned off Net Barrier and can now connect to the internet. I turned it back on and can't connect to the internet. I contacted Intego and they are aware and working on a fix. So if you have Net Barrier just turn it off. Virus Barrier is still on. Hope this is of some help.

@LuisSequeria - In an earlier reply you suggested to install Etrecheck, then you say " Do not install intego or other useless stuff." Both Etrecheck and Intego are available in the App Store. Is there any way to know what is useless and what is useful stuff in the App Store ? Is there some rating system somewhere?

Today I upgraded to Catalina version 10.15.1 (19B88) and sudden;y my safari broaswer has slowed to almost a halt in opening the most simplest of pages e.g. Google, this is not acceptable as my Mac is my primary source of income

Same problem. Was on the phone with support for an hour but no solution.

Here's the report. I can't see an obvious problem.

Agree 100%. The 2 things you don’t screw up are internet access and email....

Yes it fixed it, but sitting home I don't need Intego, but it has saved me a couple of times in other countries where the internet is not my home's internet.

It is of course your preference

Me too
