Safari Update to 17.3 Fails With Error. macOS Ventura.

I suspect you may be right about this.

As update, I get the same failure to update Safari on a virgin installation of Ventura on an external ssd. So this is unrelated to any other software but the OS and the hardware, an M2 MBA in my case.

All other updates have gone just fine for the past three months that I've had this machine.

I can also report that Safari 17.3 appears to run just fine if I boot to fresh Sonoma install on an external drive, though I've had no opportunity to run any update(s) under that OS.

Yes! The problem appears to have been resolved by Apple this past weekend and the update to Safari 17.3 is now successful on the M2 platform. 🙂👍🏽

Like you, I found a download source for the installer package and tried a manual update, but no joy here either.

This particular line in the Install log seems relevant, but I'm no coder so what do I know?

❝Failed to run script graftCryptex.sh at /Library/Apple/System/Library/InstallerSandboxes/.PKInstallSandboxManager-SystemSoftware/B3D5B954-830B-4331-8F8C-A1A23A46C866.activeSandbox/OpenPath.H5t716/Scripts/com.apple.pkg.Safari17.3VenturaAuto.XiZ2HB/postinstall line 45❞

After that the installer seems to wrap things up and throw the error message GUI.

I think I'll do an OS reinstall and see if that resolves the problem.

Regarding traction for this issue, I did ship feedback to Apple via this:

Hey, PRP_53, thanks for this.

Though the thread you linked didn't provide a solution, it did prompt some exploration on my part. From my install log I found the location where Software Update was downloading the update from, and with that info was able to download the standalone Safari17.3VenturaAuto.pkg myself. Unfortunately, running the installer manually resulted in the same failure and error message.

The log shows the installer progress and apparently the fail point, too.

I think there's little I can do until this scripting error maybe gets more traction and Apple revises the update package, but I'm not holding my breath.

I could reinstall macOS and try again, and maybe I will do that. But this is just a Safari update and as far as I can tell, Safari isn't broken.

Update:

After reinstalling macOS 13.6.4 which includes Safari 16.6, I ran Software Update again.

Unfortunately I got the same update failure. 🙁

I guess I'm stuck w v16.6 until the next update or until I upgrade to Sonoma, whichever comes first.

I did also run an EtreCheck report, but I see no clear indication of conflicts here.

That's an interesting idea, but I wouldn't know how to give full disk access to a package file.

In any case, though, I assume Apple's installer already has full disk access by the nature of the tasks it is required to perform. To say nothing of the fact that the same installer does the OS updates, and that went off just fine.

Thanks for the idea, though I don't think I'll go down that rabbit hole after taking a quick look on the webz about it. 🙂

And still unable to complete this update today.
