To use Canon Print Studio Pro, you will need to set Photoshop to open in Rosetta mode.
1. Make sure Photoshop is NOT running.
2. Go into the Applications folder.
3. Open the Adobe Photoshop 2024 folder.
4. Select the Adobe Photoshop 2024.app and Get Info (cmnd + i) to get the Info window for Photoshop. (see figure 1 below)
5. Select the checkbox next to Open using Rosetta
6. Close this window, and then launch Photoshop.
7. The Canon Print Studio Pro plugins will now load.
Please note, this feature WILL eventually be going away when Rosetta is end-of-lifed in a future MacOS Release.
