Safari loads web pages extremely slowly
2019 i9 iMac: Everything seems to run fine EXCEPT Safari. The Apple webpage loads promptly, but every other webpage I have tried to load takes a VERY long time to load--one webpage took over 1:35 to load, while my 2016 MBPro sitting next to it loaded the page in less than 5 seconds--both on my WiFi network. Apple Support had me reinstall the OS--latest version of Catalina--but that did not help. I do have Intego Antivirus on the machine, but it worked fine with Intego AV before--although that was perhaps before the latest update. Even running in safe mode, however, Safari loads pages extremely slowly. Any ideas--could it be the latest OS update does not like the
Intego AV software?
