A notifier that warns you when macOS is about to crash.

crash-percent.js

// This is JXA, i.e. you can't run it with plain `node`. Use `osascript` or the Script Editor.
// I recommend exporting it to an `.app` and running it at login if you have my same issue.
// Requires this script: https://gist.github.com/LoganDark/b8c74e14c06b77e6f16d4492c5bda928

// CONFIGURE crashPercentScript in run() to point to your script. Make sure to chmod +x to make
// it executable.

function getCrashPercent(app, script) {
	return +/\d+/.exec(app.doShellScript(script).split('\r')[0])[0]
}

function run() {
	const crashPercentScript = '/Users/LoganDark/.bin/crash-percent'
	
	const app = Application.currentApplication()
	
	app.includeStandardAdditions = true
	
	console.log('Displaying startup dialog')
	
	app.activate()
	
	const result = app.displayDialog('Corruption notifier has been started.\r\rYou will be notified of your system corruption every 5 minutes once corruption exceeds 90%.', {
		withTitle: 'Info',
		buttons: ['OK'],
		defaultButton: 'OK',
		timeout: Infinity
	})
	
	console.log('Waiting for corruption to exceed 90%')
	
	while (true) {
		console.log('Getting corruption percent...')
		
		const crashPercent = getCrashPercent(app, crashPercentScript)
		
		console.log('Corruption percent is ' + crashPercent)
		
		if (crashPercent >= 90) {
			console.log('Corruption >= 90%!')
			
			break
		} else {
			console.log('Corruption is fine... for now')
			
			delay(5)

	}

Hi, this app stops responding as soon as I click OK on the first notification, what should I do?

@Patrik-svobodik Sorry for taking so long to respond, but it's not supposed to respond or bring anything else up until system corruption reaches >90%.

Once it does that, it will pop up a window.
