can't attach files with Safari

Great analysis, thank you. Can you share how you reverted Safari back to 14.0 please?

see my reply posted immediately above your comment.............

Hi remlub101.Sorry if I bother you but i have again this problem,i can t unerstand why.Yesterday it was fine. I have the automatic update box checked...that s the reason?

Thank you for that - I feared the worst and you confirmed it!

This problem still exists. Drag and drop works for some things, but it doesn't work in parts of Canvas for example.

I'm using Safari and all of a suden I can't attach docs. from my computer. what can I do?

I cannot attache files using safari to Yahoo email. I've had this problem for a few months and cannot fix it. Many people have this problem with Yahoo and gmail. Why is Apple not fixing this?!!

HI All - I've been having same problem (loading photos up to Ebay)

I've read many of the threads concerning this, and have worked through suggestions.

IT IS NOT A MOJAVE issue as such...following advice above I reloaded Mojave 10.14.6... upload worked fine (using the installed Safari 12.1.2)

IT IS NOT A SECURITY UPDATE issue...following reload of Mojave and Safari 12.1.2, I then in sequence loaded the 2 security updates 2020-005 and 2020-006....again no problem upload worked.

IT IS NOT A MOJAVE SUPPLEMENT ISSUE...... I then added the macOS Mojave Supplemental Update....this introduced Safari 14.0....again no problem uploads continued to work.

IT IS....IT IS....a SAFARI 14.0.1 ISSUE....so finally I added the Safari 14.10.1 update... lo and behold uploads stopped working.

So I have no solution, but my workaround keeps me on Safari 14.0 and therefore functional, 14.0.1 clearly doesn't work with Mojave, and maybe not with Catalina (according to some posts).

Hope this helps... I've logged with Apple Support.

I can confirm that I am experiencing the file upload bug on my MacBook Air and iMac 5k. I am a Web Designer and this bug has impacted me negatively. I'm also quite underwhelmed that there has been no acknowledgement of this issue from Apple.

Is anybody aware of an ETA for any kind of fix?

Looking around this safari forum, lots of people having similar issue here. Guessing it is a bug. Try an alternate browser to confirm this is the issue (Chrome, as example).

Apple have broken Safari with the 14 update on Mojave it seems. Similar functionality on WeTransfer is no longer working either.

Same here. Can't attach files in Safari but can in Chrome.

Can you please fix this asap; the problem started after upgrading to Mojave 10.14.6.

In addition to Chrome, you can also attach files with Firefox.

As mentioned by Clueless-senior "drag and drop" still functions properly in Safari.
