Hi Folks, I am trying to build an electron app on a Mac with MacOS 10.10.5 Yosemite. I have been able to sign the app bundle. Am trying to notarize it now but I find that the --notarize-app option is not available. I suspect this is because of an older version of altool. 2 Questions: A) Can I notarize an app on OS 10.10.5? B) If yes, how can I update only altool? I tried to download a higher version of Xcode command line tools but I can't install it. Am stuck, so any help will be much appreciated. Regards, Arun
