Update Photoshop

Unfortunately, it seems Adobe lets Photoshop 2026 (ps ver 27.8) install on macOS Ventura 13.7.8 even though it does not work and the system requirements don’t list Ventura as supported. We experienced this for ourselves on a 2017 iMac running macOS Ventura 13.7.8

What year is you iMac?

Have you checked to see if you can update to a newer version of macOS?

I am a Windows user, but as far as I understand,the minimum system requirements for Photoshop v27.x is Mac OS 14.x as shown in the attached link :

​@JohanD you can install version 27 alongside version 26, so you can have the 2 versions installed at the same time
