P: Error at loading of ippCV library

I search on /usr/local/opt the missing library designed by the error log and opt directory is not existing on my Mac........

It looks another Library missing ???

Thanks dghazfan. I tried it but still not working with this log :

I noticed that before I made the replacement, the dylib had an alias inside the Frameworks, so I changed the alias to the new one but no change, still not opening

The fix for MACOS can be downloaded from here:

https://www.sendspace.com/file/meab5g

Unzip the file and copy the resulting libopencv_world.4.4.0.dylib file to replace the same file in the Photoshop 2021 installation directory (/Applications/Adobe\ Photoshop\ 2021/Adobe\ Photoshop\ 2021.app/Contents/Frameworks/libopencv_world.4.4.0.dylib).

This fixes the problem an PS runs just fine.
But disclaimer as usual - all this at your own risk.

OpenCV library was taken from official release of OpenCV 4.4.0 on GitHUB (https://github.com/opencv/opencv)

For apple macos users, the FIX is here:

Some where either in this thread or on a related one, there is a post  that includes information from Heise Verlag, a German tech publication, which sheds light on the real underlying issue. As I recall, that post says that the Adobe code is compiled with INTEL compiler that that uses newer or different instruction regarding AVX2 512 which the AMD processors cannot understand, causing it to have to to revert to SSE 4.2 . Search for that post for more accurate detail than I have here. So the answer to @Richard1967L_9jb02bijdrjjo would be that possibly most AMD equipped machines would be the affected ones
 

Out of curiosity, does anyone know how many people/computers/subscriptions are affected by this upgrade?

It seems they hit against quite a few people because of the commonness of the mentioned processors.

I do have a problem here. I erased the older versions and now don't know how to get them back. I'm currently using 21.2.4 and it's not working properly (Rotate is completely inoperable). How do I get back the earlier versions? Anyone know? Especially 21.1.3 (Wasn't that the version everyone was reverting too?).

Help!!

Thanks! It works nice. Guys from Photoshop want us to buy new cpu?! Unbelivable.

@shad0w thank you!!!!!!!!!!!!
