I am using Macro Express 5
Parallels on iMac 2019
MacOS Monterey
Windows 10
The program I am trying to use with Macro Express with is Lightroom Classic V12.1
What I have discovered so far.
I create macros by starting with "capture macro".
I must use "Begin capture in window "Last Active Window"" otherwise I never see the next screen "Start Capture".
Capture process goes fine.
Here is the big deal, and the thing that was really causing me problems. I was using an alt/option key combination to activate the macro (specifically alt-3) . If I did that, I had to hold the activation key (alt-3) down for at least 1/2 to 3/4 of a second for the macro to activate. If I pressed and released quickly, all I heard was a beep. No macro activity occurred.
Lesson learned. Don't use alt/option combination to activate a macro, at least when running on Lightroom Classic.
For what it's worth, I now use ; (semicolon) as my macro activation key, in Lightroom, in the develop module.
Hope this info helps somebody.
