how to downgrade from safari 13 to 12??

so I've had it with Apple for good. There you set up the browser the way you want to use it, and then Apple shoots the extensions in the browser with an update. I will shoot down Safari and use Firefox from now on. I need the Mac to work. I don't want to constantly have to deal with the operating system like a Microsoft user or Linux freak.

Yes, you're right, I thought you were the OP on this thread. If you decide to troubleshoot Safari 13 instead, have a look here:

Browsers Protection for Safari and Adbloc… - Apple Community

If that doesn't help then I'd suggest creating your own post. You'll get more attention that way and it will be Safari specific.

When I attempt to restore the previous version of Safari, I get an error message "Safari" can't be modified or deleted because it's required by macOS.

Do I have to completely restore a previous TM backup?

my concern is that in doing a complete restore other files that I have made changes to will be overwritten with the previous version.

How can I do a selective restore?

Or would doing a reinstall of High Sierra resolve my problem?

You can't do a selective restore for that. If you do decide to restore you could make a copy of the files that have been overwritten and then copy them back after the TM Restore. I'd assume that TM would also keep the update from today, so you might be able to restore from that.

Same here, Safari13 broke the ability of adding Google accounts to `System Preferences > Internet Accounts`, therefore leaving me without Google Mail, Calendar & Contacts.

Reverting to an older Time Machine backup means I will be loosing 15 days of data, which is a significant loss.

Having the ability to revert to an older version, at least as a dev. would do no harm.

Hey apple, thank you for shutting down all my extensions! And forcing me to use Chrome as default browser, good job Apple :(

What about adding video calls support for Facebook Messenger in 2019 instead of cutting already poor functionality in Safari?

MAKE SURE YOU MAKE A DISK IMAGE CLONE OR BOOTABLE CLONE OF YOUR EXISTING HD ON AN EXTERNAL HD AS A FAILSAFE!

On High Sierra I had this issue and what worked for me was to selectively restore from my Carbon Copy Cloner backup the System Folder, Library and the old version of Safari from before the Safari 13 update. I searched for folders named Safari within my User account and restored those too. All other User data was left untouched.

This may work in Time Machine too but I haven't tried it.

I have bigger problems. By upgrading to Safari 13, all Selenium automated tests for Safari that I've developed are now failing and no one on the internet seem to have a solution yet. Still working on Safari 12 without any issues but since I have upgrade to 13 on my work Mac now I am blocked by this issue. I should have known better since not the first time I have to deal with something like this whenever an update is released. Some are saying reload Mojave to get Safari 12 back , sounds like a risky approach as I wouldn't want to lose data and rebuild from scratch.

Agree with you about Safari. Though you have bigger problems if you’re using Chrome and Facebook.

Apparently, despite the fact that Apple considers Safari to be an "integral part of macOS", they update it EVEN IF you have "Install macOS updates" turned OFF, like I do. (Way to mix your signals, Apple!) I lost half a day's work and the entire weekend restoring from backup because Safari 13 botches extensions and eliminates WebClips -- which is the reason I am NOT upgrading to Catalina, as I still use Dashboard a dozen times a day.

If you restore from backup, be sure to go to Software Update, click Advanced, and uncheck EVERYTHING, even "Check for Updates". Otherwise Apple with screw you over all over again.

To downgrade Safari 13 to Safari 12 is such an easy task. I have done it on two Macs.

I am assuming you are running Mojave or High Sierra but this works with any OS, I have tried it several times.

Safari and other applications are part of the OS and can't be removed or replaced individually.

Take your Bootable USB with your respective OS on it, which you made for each OS as you progressed through OS upgrades...What!! you never made a bootable USB or kept your original install discs for each OS. Oh dear.

For you real clever people who made Bootable OS's, Insert it and boot to it and reinstall you OS. It will install the original OS and leave all your settings as the were including Safari but with the previous version.

Time Machine had good intentions but never really worked the way you want it, data loss, etc, etc.

Thank god for Bootable USB's and Install discs.

Yes , Apple did make a mistake putting out an update for Safari 13 and 12 for High Sierra and maybe other OS's but it is easily fixed without losses.

Use your Time Machine backup to restore to a time before you installed it.

I was able to downgrade by reinstalling from the macOS Recovery Partition. ⌘R option worked like a charm https://support.apple.com/en-us/HT204904

Do you have a complete Timemachine from just before you upgraded Safari?

Then recover that one completely.
