Safari Upgrade causes problems with many websites

I would be very cautious about downloading a Safari installation package from any non-Apple website. The downloads sometimes contain adware/malware. If you want to download from a non-Apple website, I suggest you do a backup, preferable 2 separate ones on 2 drives before downloading. That gives you a way to recover, should it be necessary.

Thank you. I was hopeful. But unfortunately that did not resolve the issue, even after a restart. And for the record, I'm also having a problem with Apple Mail now. Contents of message window is not rendering.

Carsten275,

You are a hero. Thank you. This link to a Safari install file worked perfectly. I was going crazy trying to troubleshoot this. Bless you!!

I had just installed High Sierra 2 days ago, and activated Adblock Plus Control Panel. This problem just started today with every website I tried to open in Safari. Safari working perfectly now.

Deep thanks,

Karen

carsten275's solution worked for me on High Sierra, thanks a lot.

How did you obtain the links to these packages?

Are they referenced on any Apple support page?

As useful as these fix package are, people should refrain from installing random packages referenced on a forum without knowing who's distributing them and what is their supposed purpose.

Download is from Apple's website so it's probably safe, but we don't know much more than that for now.

This worked for me too! Thanks so much. I've had this same problem since upgrading to Safari 13.1 a month ago. Just curious where you sourced this download? I couldn't find any Safari downloads in the apple store.

Thanks again!!

I'm running running Mojave (10.14.6) and Safari 13.1 and I'm seeing a lot of sites that I work on, not loading images or Safari is running super slow. I've never had a problem with Safari on my iMac. I guess I'll be using Chrome for awhile until Apple can fix whatever is broken. Sigh.

I am a long time Apple user and reader of these forums but rarely post. After reading many forums and threads and being stumped by the Safari 13.1 javascript error for nearly a month, I just wanted to say thanks for this carsten75. It worked for me on High Sierra and the troubled websites are now working again.. I was just about to do the OS reinstall as many have recommended but am glad I had one more search for topics on this. The Safari reinstall from Apple on the link you posted (it's on page1 of the thread) installed just fine and I can now cross this off my tech fix to-do list. Thanks again.

Meanwhile the link on page 2 is deprecated for 13.05 due to the new safari version 13.1:

Only for Mojave - as already posted on the first page: http://swcdn.apple.com/content/downloads/02/03/061-61260/wpceq4s7wuww8z0v8ukjmx4r9dfelkma2f/Safari13.1MojaveAuto.pkg

But keep in mind some Mojave users could not solve the problem by reinstalling Safari.

I have the same issue with Safari as described above in the thread. It seems that these updates broke Safari and the comments above indicate a re-install to fix the issue. I am new to working with MAC OS and Safari.

Can someone point me to the Safari install download? Also would I need to uninstall Safari first or can I install over what is there?

Thx for the assistance.

So if I understand you correctly, there is no fix for 13.1.1?

I'm using High Sierra and my problem only started when I upgraded to High Sierra and to Safari 13.1.1 - Ironically, I can't even access this very site using Safari - had to switch to Chrome, grrrrr.

After 2 long calls with Apple and trying many different things, I was left with having to re-install OS X 10.13.6 and then notified I need to update Safari to 13.1.1 (1st installed this OS X and Safari 10 days ago and many problems since, e.g. can't get into iCloud). Today, after the re-install and latest Sara version update, the problem persists! Am so very frustrated.

My next step is to try updating to Mojave and hope for better Safari performance (my iMac can't handle Catalina). If you have any insights into Mojave installation, I'd appreciate it.

Are you suggesting installing a package intended for Safari on High Sierra, on other versions of MacOS that are having this problem? Personally I'm on Mojave. What about Catalina?
