Photoshop v20.0+ slow on macOS Mojave

[Lorenzo Schiff]

Hi

i have an Imac with i9, Vega 64, 32gb DDR4 ram and a ssd as hard disk.

Photoshop v20.0+ have huge delays for any task (from a simple brush usage to complex filters).

It's just unusable:

- to open a raw from camera raw to photoshop it takes 20 seconds

- to make 20 brush clicks into a mask it takes 8-10 seconds

- to open a filter windows it takes >5 seconds

Every damn task takes several seconds to be completed and in the while all the macOS starts to be very slow (like into a bottle-neck).

The rainbow wheel is omni-present.

I already tryed every single fix in this community (privacy fix, performance check, ecc...) but the only solution is to install the latest v19 release.

How is this possible?

Is the support alive in this forum?

Hi There,

Sorry to hear about Photoshop's slow performance on macOS Mojave, could you please let us know the exact version of Photoshop you're using? 

Also, have you tried deselecting "Use Graphics Processor" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

You may also try optimizing the performance of Photoshop by following the steps mentioned here: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

Regards,
Sahil

The versions i have issues is any >20.0

(in this moment i'm trying the 20.0.6 20190724.r.80)

deselecting "use graphics processor" doesn't change the issue.

Applying every single step in the link you posted, doesn't change the issues.

I already tryed everything already explained in this forum. And like many other users, there is no public fix to this issue.

To be 100% clear:

I use the same, exact, preferences of version v19.

The version 19 works like a charm, the 20+ is just unusable at all.

Hello?

[Lorenzo Schiff]

Any REAL support here?

Does support team exist or are they just bots?

No ticket system = no proper support at a scale as large as Adobe/Photoshop.

Have you tried resetting your Photoshop preferences

Using the Adobe cleaner tool

I'm not a Mac user but I have no issues with performance on Windows 10 with Photoshop CC 20.0.7

Photoshop v20+ works like a charm in my 300€ laptop (windows 10).

I already resetted the preferences under mac.

Sorry but I can't be of much help as I mentioned I use Windows only, maybe try contacting Adobe Customer Care
