NSRunningApplicationでアプリケーションプロセス情報を取得

AppleScriptで他のアプリケーションプロセスの情報を取得するには、OS標準装備のSystem Eventsに対して、

tell application "System Events"
	set aProp to properties of process "Safari"
end tell
--> {has scripting terminology:true, bundle identifier:"com.apple.Safari", file:alias "Macintosh HD:Applications:Safari.app:" of application "System Events", creator type:"sfri", subrole:missing value, entire contents:{}, selected:missing value, application file:alias "Cherry:Applications:Safari.app:" of application "System Events", orientation:missing value, role:"AXApplication", accepts high level events:true, file type:"APPL", value:missing value, position:missing value, id:909534, displayed name:"Safari", name:"Safari", class:application process, background only:false, frontmost:false, size:missing value, visible:true, Classic:false, role description:"application", maximum value:missing value, architecture:"x86_64", partition space used:0, short name:"Safari", focused:missing value, minimum value:missing value, help:missing value, title:"Safari", accepts remote events:false, total partition size:0, description:"application", accessibility description:missing value, enabled:missing value, unix id:3386}

などと操作することになります。ただし、System Eventsがつねに使えるわけではありません。

Mac App Storeに出すアプリケーションの中だと、些細な用途に他のアプリケーションを呼び出そうとしても、よほどの理由がないかぎり通りません（リジェクトされます）。Dark Mode/Light Modeの検出に安直にSystem Eventsを使おうとしてリジェクトされた経験があります。

そこで、他のサービス（shell commandとか、Cocoa Frameworkとか）を経由して機能を呼び出すことになります。まったく同じことができるわけではありませんが、１つの目的に対して複数の方法を用意しておくのはセオリーです。OS側でバグを作られた場合の回避策とか（正しくないOSバージョンを返してくるmacOSがありました）、目的に応じて利用に制限がかかる用途（まさにMac App Storeがそれです）があるためです。
