MacOS 15.0. Changing size of brush, eraser tool, ... does not work anymore with mouse right click.

[DirkD]

Since updating my Mac OS to version 15.0 (Sequoia) I can't change the size of brush, eraser tool, etc... anymore with a mouse right click. I used this way for many years already, but it does not work anymore since updating to OS 15 (Sequoia) two days ago. Also the other shortcuts don't seem to work anymore. 
I am using PS 25.12.0.
I then have to use the brush preset picker in the top horizontal toolbar.  And here another issue comes up. The options appear behind the open image, so I still cannot change the brush size without dragging the image out of the way, or make it smaller.  
Some of the other items in the top horizontal toolbar (tool preset picker, opacity, flow, ...) open behind the image also. 
I did a search but could not find any info about these issues (yet).

@DirkD can't help with the brush issue as I'm on Windows and not experiencing that problem, but have a look at this thread in relation to the second issue

@DirkD From the PS Team - "MacOS Sequoia got released to public on 16th Sept. Photoshop 2024 is yet to receive an update for compatibility with macOS Sequoia. "

@Kevin Stohlmeyer I was on a chat with Adobe support this afternoon. The PS update should arrive somewhere in October and hopefully these issues will be solved. Fingers crossed.

@Ged_Traynor Thanks for pointing me to that thread. 
Application Frame is greyed out in my case.
Anyway, I chatted with support and will wait for the next update in October. We'll see what happens.

The Option+Control+Left click and drag left or right to change the brush size works here with macOS Sequoia 15.0

on a 2022 Mac Studio.

The reason that Window>Application Frame is greyed out is most likely Enable Native Full Screen is checked in Photoshop 2024>Settings>Workspace

Perhaps a reset of the Photoshop preferences will fix the keyboard shortcut issue:

@Jeff Arola Thanks Jeff! Yes, resetting the prefs fixed the shortcut problem. 
And also, unchecking Enable Native Full Screen fixed the greyed out Application Frame and this solved the problem of the tools that were hiding behind the image. I don't like the cluttered screen because of this action but it's what it is for now until Adobe fixed the issues. 
Thanks again!
