Plugin won't launch

[MEB]

Hi @PGPhoto,
Welcome to Affinity Forums
To what plugins are you referring exactly? Nik Collection 4? It's the exact same thing with Photoshop. If the plugins were NOT optimised for M1 the only way to run them is to force the host app to run in Rosetta mode (emulation).

Nik collection 3 and Topaz Studio 2 run with Capture One.

Hi Meb, thanks. Do I understand correct, you suggest to authorise access to / (root)? - I've been working for 15 yrs als Unix sysadmin and that workflow makes me nightmares.

I tried also the DxO page you suggested and I got (copy & paste of the link you posted below https://help-nikcollection4.dxo.com/install_activate):

(This forum editor urgently needs the ability to resize images 😆)

This plugin thing turns out to be a "crackling nut". - (I have no clue how to translate this into English. In German it's "Knacknuss", an artificial word, put together of "knack/crack" and "Nuss/nut" - Because some nuts suppose to be cracked only very hard, the meaning is a problem hard to be solved).

Hi @Roland Rick,
I will let you know if/when i receive a reply from them.
I have Luminar 4 and Ai here but never tested them with Affinity Photo. Make sure you give Affinity Photo root access: click the Authorise Global button once in Affinity Photo, Photoshop Preferences section, then press the Authorise button again in the Finder window that will open next - you should see a forward slash in the first line in the Plugin Supports Folder section. Remove all the others you may have added there since they are not required if you give Affinity Photo root access). Also make sure you have Allow "Unknown" plugins to be used ticked. In any case i will install and check them myself too.
Regarding Nik Collection, i don't have the latest version (didn't updated to 4 yet) but i know that some Nik Collection 3 plugins do work with Affinity Photo MAS version (Viveza however crashes consistently in the MAS). I don't mind updating mine to check this also.

Meanwhile DxO have installation instructions specifically for Affinity Photo here (scroll down up to the Installing Serif Affinity Photo* section) that may help you out.
