Safari update 14.0.1 issue uploading files

@Tumbach you re-installed Mojave ? Guess I'll try that as well ... Thanks

Thanks for your more technically correct set of instructions. I have a fairly new Mac that came with Mojave.

Please follow Eric's instructions.

God bless auto correct - clearly I meant SLEDGE HAMMER

I can drag and drop but not attach.

It'd be handy if there was a simpler way than a full OS reinstall i.e. a terminal command or sumfink.

Same problem here. It's unconscionable that Apple would create such a MESS! Fix it!!! I loosing confidence in Apple products and software. . . sad!

I'm having the exact same issue (Safari update with Mohave 10.14.6) and it's very disturbing. Makes me feel like not doing the updates when offered in the future.

Has anyone found a solution?

hello, i have the same problem too. Apple needs urgent updates. I am using Mojave 10.14.16 and Safari 14.0.1.

After latest Mojave update (10.14.6) today, I can no longer attach documents on email (either gmail or yahoo). I have already quit Safari twice, and shot down and restarted. The problem persists.

Same. Upgraded to Mojave and can't upload anything anywhere in Safari.

High Sierra worked like a charm.

Any updates to this problem??

Frustrating that Time Machine doesn't allow restoring previous working version of Safari :-(

It won't allow me to overwrite the 14.01 with the earlier 14.00 from a Time Machine back up

Tried renaming it / duplicating it / moving it but it seems like its treated like a system file.

How do you do this?

No offense friends... but can anyone tell me how to opt out of this discussion!?

My input is done.

Thanks.
