new venture 13.1 has messed up my computer

Hello marianne9851,

Thank you for reaching out in Apple Support Communities. There are steps available that can help. We recommend to follow these steps:

"Reload the page

To reload a page, choose View > Reload Page, or press Command-R. If you can't reload, make sure that you're connected to the internet.

If you still can't reload:

1. Press Command-Q to quit Safari. If Safari doesn't quit, press Option-Command-Esc to force Safari to quit.
2. Open Safari again and try to load the page. When Safari opens, if it automatically opens pages that you don't want to open, quit Safari again, then press and hold the Shift key while opening Safari. 

Check Safari extensions

If you installed any Safari extensions, make sure that they are up to date.

You can also try turning extensions off. From the menu bar in Safari, choose Safari > Settings (or Preferences). Click Extensions, then deselect the checkbox for each extension to turn it off. Learn more about Safari extensions. 

Check Safari settings

The webpage might not be compatible with one or more browser settings, which you can turn on or off as needed. From the menu bar in Safari, choose Safari > Settings (or Preferences). Then click Websites, Privacy, or Security to access these settings:

• Websites settings. These settings can be configured for specific websites.
• Privacy settings. These settings apply to all websites.
• Security settings. These settings apply to all websites. 

Test with a private window 

A website can store cookies, caches, and other data on your Mac, and issues with that data can affect your use of the website. To prevent the website from using that data, view it in a private window. From the menu bar in Safari, choose File > New Private Window, or press Shift-Command-N.

If that works, use the following steps to remove the website's data, including its caches and cookies. The website can then create new data as needed. If it's a website that you sign in to, make sure that you know your sign-in information before continuing.

1. Choose Safari > Settings (or Preferences), then click Privacy.
2. Click Manage Website Data.
3. Select the affected website from the list shown.
4. Click Remove.
5. Click Done.
6. Open the website again in a non-private browser window.

Install software updates

Install all available Apple software updates, which can include updates for Safari.

Check VPN or other security software

If you installed VPN or other software that monitors or interacts with your network connections, that software could affect your use of the website or the internet. Learn about network issues related to VPN and other software. 

Check network settings

Certain network settings, such as those related to using a proxy server or custom DNS server, can affect access to content on the internet. Even if you haven't changed your network settings, you might have installed software that changed those settings for you.

To find out whether the issue is with the network settings on your Mac, try viewing the website from some other device connected to the same network.

To find out whether the issue is with your network itself, try viewing the website after connecting to a different network.

Resolve other issues

• If Safari appears to be stuck on an unexpected homepage
• If you want to block pop-up ads and windows
• If you deleted Safari and don't have a backup, reinstall macOS to put Safari back in your Applications folder. Reinstalling macOS doesn't remove data from your computer.

If you still need help, please contact Apple Support."

Kind Regards.

My facebook page keeps jumping around and downloading new things all the time so I can't even go on my Facebook using Safari. I have to manually switch to chrome and log in that way. Im so upset. My Mac air seems to be a lemon. This is the third time I have problems with it.

This issue to date only appears on Facebook, whose founder's motto is "Run fast and break things."

I do not think this is an Apple problem.

it is Facebook's problem to cooperate with existing current Browsers. if Facebook finds their new features are causing problems for users, then Facebook need to reach out to Apple to find a solution.

Be sure you let Facebook know you don't like it. Every other site seem to be working just fine, and Facebook was working fine until recently.

It totally screwed up my computer. I can't switch my browser to Chrome. My facebook page keeps jumping around and downloading new things all the time so I can't even go on my Facebook using Safari.
