    1. “However, the reason behind this is, the person who have Mac or iPhone they face any problem in Safari, they move to Google Chrome.

      Instead, they should try to fix Safari complications”

      looool.
      No, they should use whatever works. Safari has no excuse, I’m sorry.

      PS: Yes I miss the handover and shared ios macos tabs too… but, a non-functional browser is a non-functional browser…

      PS2: I am still wasting time with relogins from your fist solution… So you say I should reinstall Mojave… when there are other browsers that work just fine… again: looool

    2. With Windows 7, Google was fast downloading. I have recently switched to an iMac and have been driven mad by the slowness downloading web pages – sometimes it sticks part way through and I get nothing. I switched to Bing – that was as slow. In desperation I tried DuckDuckGo. Pages are downloaded instantly. I have no idea why, but it work, so I’ll stick with it.

    3. Solution 10: how do you reinstall Mojave?
      Thanks

    4. For your information, I have restored Safari normal speed on Catalina by deactivating my Intego Netbarrier suite

    5. I upgraded my MacBook Pro to Catalina a couple of weeks ago and all was good. Today I upgraded my MacAir and I basically can’t connect to the internet using the wifi that I used before to download Catalina and the same wifi that I am using on the Pro to find your website and to send this message. I tried deleting the cache and reopening Safari and restarting but still nada.

      What’s up with that?
