    Ok, today I finally got rid of my issue with the LogiOptions not loading on my Mac, with the pesky "extension not signed" error message (and it seems that there is nothing wrong with the extension - read ahead).

    This worked for me, at least under macOS.

    Running latest macOS, latest Photoshop and latest Logi Options for macOS (as of May-18-2021).

    What I did:

    - Closed photoshop (not just minimized)

    - Open Logi Options, go to applications on the top right, scroll over Photoshop and delete it (click the X).

    - Close Logi Options and open Photoshop (will process the removal)

    - Close Photoshop

    - Open Logi Options, got again to Applications, scroll down to "+ Add Application" and add Photoshop back. 

    - Close Logi options and reopen Photoshop to  processes the addition.

     

    It should be working now.

    But what when turn off your Mac and turn it on again? Does it work?

    Still working after a reboot, including side buttons and scroll wheel. I see no reason for it not working.

    It's not a matter of the extension not being properly signed but rather something that changed in the settings or integration. Removing and reinstalling the extension using Logi Control solved the problem, at least for me.

    #####  MAJOR ANNOUNCEMENT  ###### READ THE POST FROM aviegas ABOVE

    I JUST TRIED IT AND IT WORKS, AFTER 6 MONTHS MX 3 THUMBWHEEL NOW CONTROLS BRUSH SIZE IN PHOTOSHOP.

    WELL DONE AND THANKS TO AVIEGAS FOR POSTING A SOLUTION... WHERE DID YOU GET THIS FIX?

    FYI, I am running latest Catalina on a 16" MacBook Pro with Photoshop 24.4.0, Options 5.50.210.
    Logitech support should build the update process to action the same steps with no user intervention.

    I've been plagued with this issue for a few months now, hoping that each new version of Logi Control would provide a fix (ie come with a "properly signed" extension). Googling I found out people fixing "extension signing" issues on Windows by adding hacks the (in)famous windows registry. This prompted me to think that the issue was more a corrupt setting, rather than proper signing of the extension.

    I've examine several plists related to Photoshop and Logitech in search for a clue and after getting nowhere, I thought that a possible solution could be to *completely* remove all references to Logi Control from within Photoshop and reinstall the extension. I tried just reinstalling Logi Control once again and after it still failed I recalled that there could be application specific settings (something wrong in the settings/missing something/etc). Then I had the idea to just reinstall the settings/extension/integration in hope that it would remove any leftover from previous versions and install a settings/extension that was consistent. Had to try a few times to figure out that correct sequence. And boy, I got really happy when it worked!

    This is a common problem in software updates. Some leftover from a particular older version causes the software to fail.

    This is the reason why I always reinstall (clean install) on all my devices on every major version and update on minor ones. I do that on macOS, iOS, iPadOS and even on WatchOS and tvOS (those two are harder to do a fresh install). Windows is even worse (better for frequent fresh installs).

    I have tried this a few times with Big Sur on an M1 Mac mini and I’m still not getting thumb wheel functionality. Can anyone else confirm they are getting it on a similar OS/hardware? Thank you either way, I’m glad some people are getting it to work for them.

    Hi!

    Thanks for the tip, I’ll give it a try tonight.

    But I’m afraid I’m in a slightly different situation as I already deleted the Photoshop app from Logi Options, but the popup is still displayed. I’ll try to enable / disable / enable again and see what happens 🤷‍♂️

    Cheers,
    Didier

    Mac Mini 2018, Big Sur OS, Photoshop 22.4.0, LogiOptions 8.54.147  <<< --- all this soft is clean installed.

    Brush size in PS works OK until restarting Mac. Then it doesn't work anymore!

    Cheers,

    Piotr

    From what I see there are 2 different issues being reported/handled in this thread.

    1-The extension failing to load in Photoshop, causing the error popup when Photoshop starts and no of the supported advanced features work. This is what I was experiencing.

    2-The extension actually loads, but some of the expected functionality will not work, for example, changing the brush size with the horizontal scroll wheel on MX Master 3 mice.

    All I can say is the for me, the procedure that I posted solves problem #1 allowing the extension (and as a consequence the profile) to load.

    As for #2, it can be a real problem in either Photoshop (changing/bug in the API) or a bug in Logitech's extension. I don't own a MX Master mouse, so I can't test it (I use a MX Anywhere 3 - I'm left handed and the MX Master is "leftofobic" :).

    One thing I can suggest to try: double check the assignment of the horizontal scroll wheel in Logi Control. Or reset the defaults (not reinstalling the extension, but just resetting the profile). Remember that this must be done with Photoshop CLOSED, and to close Logi Options before reopening Photoshop (ain't PLISTs a beauty!).

    Hi!

    I just tried again and indeed, it works :)

    In my case, I already deleted the Photoshop profile when it started to fail some months ago, but for some reason Photoshop would still say it can't load the extension upon startup.

    So tonight I enabled the Photoshop profile in Logi Options, ran PS : still not working.

    Then I reached your instructions, aviegas, so I disabled / enabled again the PS profile, and it's now working. I'll confirm it keeps working after the next reboot but I see no reason it would fail now.

    Thanks for the heads up, I'm glad it's finally fixed!

    Cheers,

    Didier

    Oh no! Back to square one now. Aviegas's instructions have worked for so long but I had to reinstall the Logitech, Options app and now, my brush size can't work any more. Any other work around to suggest? Thanks!

    Use new software Logi Options + Beta. After all, my mouse works as expected.

    Thanks. I installed the beta version and the brush size wheel works now, although an error message appears when I open Photoshop. I just click ok to make it go away. I can live with that I guess.

    If the error is the traditional "extension not signed", have you tried "deleting+reinstalling" the Photoshop profile trick?

    With the latest version I started getting the same error once again, and the following the steps described eartly in this thread still fixes the issue, at least for me.

    Thank aviegas. My "extension not signed" error is not going away even when I follow your steps. When I delete the Photoshop profile from LogiOption (or LogiOption+) and want to add it back (after closing, opening, closing and opening steps), Photoshop is in a category called "Predefined Customizations" unlike any other apps that are under "Other Applications". Perhaps this is what is causing the issue as the profile never gets deleted?
