Slow down with Photoshop 2019

I did this by accident but have now duplicated it on another MacPro... I was having the crazy long opening time for Photoshop 2019 with one specifc file that took anywhere from 22-50 seconds with a cold open of PS2019. This was on a 2010 MP 5,1 12 core 64GB AMD Radeon 7950, cruical 1tb ssd running Mojave in APFS... I wanted to put in a 2TB SSD. Accidentally, the drive was HFS+ format. I cloned Mojave 10.14.6 over with CCC and booted from the 2TB SSD not even looking at the format. PS2019 cold open of the same file... 6.2 seconds!!!! Couldn't beleive it. So, I tried another SSD with a clean instal of Mojave 10.14.6 on an APFS container. PS2019 cold open with my file: 22-28 seconds. I have another MacPro 4,1 (hacked to 5,1) 8 core 64GB AMDRad7950 running 10.14.6, crucial 1TB ssd in APFS. PS2019 cold open with my file time: 22 sec... Made a new clone to a blank ssd formated in HFS+...

Booted. PS2019 cold open with my file: 7 seconds! All around better performance opening and saving large 16-bit psds... Seems better with the GPU also in Liquify and Select & Mask. I haven't compared everything yet... I'm going to stick with HFS+ for now. I have been searching for forums on old 2010 hardware performance with APFS... Not too much info. I have a 2015 MBP i7 quad 16GB AMD RadeonR9-2GB + IrisPro1536. It opens PS 2019 with my file in 6.2 seconds in APFS... Same as the MP 5,1 in HFS+... PS 20.0.6

I've deleted all my prefs following this article and It seems to be solved. I started deleting the heaviest as the article says, but nothing happened, then I deleted all of them and it seems to be working okay. Not super fast but at least I can use a paintbrush again without going crazy.

No change here, basically have given up troubleshooting as 19 seems fine. there is a new version of 20 out, so maybe I’ll take another look, but I can’t waste too much time beating my head against the wall!

Similar problem here - Mojave 10.14.2 with PS CC2019 20.0.2 taking forever with save/open file dialogue to certain folders.

Mysterious and very irritating...

Same here. Photoshop became absolutely frustrating. Trying to use a paintbrush, even on a mask is basically impossible.

If I try to paint, first I get the beach ball, then it disappears, the brush appears again but nothing responds. There's no way to stop the process nor anything.

I've been using Photoshop since mid-90's

I've a presentation today and I don't know how to finish it. I'm typing this message with the brush cursor frozen on a photo.

I am paying for a service that I'm not getting. This is the basic stuff, if Photoshop doesn't work there is no CC.

Opening 19.1.7 takes 7 seconds. Opening 20.0.1 takes 32 seconds.

Opening a 200 mb file with a few layers in 19.1.7 takes 3 seconds. Opening the same file in 20.0.1 takes 60 seconds! (both with the program already running).

Nope, just as bad - if anything it's worse! Takes ages to perform any task, and opening a small file takes 25 seconds.

I'm having this issue also. I've noticed it occurring most of the time when making selections using either magic wand or lasso tool.

Did you update the os to the latest one? this is slowing down the PS as well as AI.

Hopefully will have a patch soon !

Mine is also very slow since I updated it to Mojave.

No, not solved. I re-installed PS 2019, but still the same very slow start-up, and beachball at every edit. Can't crop an image without a hang..
