Is Spyder5 working with macOS Mojave 10.14 and higher (and/or with the little older macOS High Sierra 10.13)? I am getting a warning message that Spyder is not optimized for my Mac
You will receive this message when starting a 32-bit application, but the Spyder software works on your macOS High Sierra 10.13 and/or macOS Mojave 10.14 system.
But please download and install the latest Spyder5 software versions 5.8 of your Spyder5 sensor (Spyder5ELITE, Spyder5PRO and Spyder5EXPRESS) from here:
Spyder5EXPRESS: http://goto.datacolor.com/download/s5x100b
Spyder5PRO: http://goto.datacolor.com/download/s5p100b
Spyder5ELITE: http://goto.datacolor.com/download/s5el100b
The Spyder5EXPRESS, Spyder5PRO and Spyder5ELITE software installers are 64-bit versions with native Apple Silicon M1 / Intel Mac support and work up to macOS 13 Ventura.
