I’ll wait for the Pro… But honestly - the last Airs and Pros are a joke especially while using a second Monitor. The Pro has a known bug and can get pretty slow. The Air - unresponsive as hell if a second monitor is used and u are in a virtual conference with screencast and cam on. We must always look at the price value tag and at that point Apple really disappointed recently. Don’t get me wrong… I am a Dev and i app…

Strange... I frequently dock my M1 Air to a 3840x2160 display and it can easily run my 30+ track Logic Pro session without any perceivable throttling.

Edit: the parent commenter does not have a miniLED iPad. If you have the 12.9” M1 iPad, the ghosting is likely due to the new miniLED backlight which was introduced with that model. This backlight is not static, but tracks to content in order to increase effective contrast (similar to FALD backlights on higher end LCD TVs). If the backlight does not track the LCD content fast enough, there can be ghosting. In additio…

It's on the 11" model, so regular old LCD model, not the new fancy microled.

No issues on my iPad you might want to take it to Apple.

No troll, the fan shutting off was how I knew my app had compiled and I could start debugging. With the M1, I now have to check the cpu usage history occasionally.

Some ideas for playing a notification sound in a script runtime:

Shell

  # system beep; also flashes the screen if you have that enabled in accessibility
  osascript -e 'beep'
  
  # play the sound file given by the file system the path
  afplay /System/Library/Sounds/Hero.aiff
AppleScript

  beep
  
  do shell script "afplay '/System/Library/Sounds/Hero.aiff'"
JXA + Cocoa API

  $.NSBeep()
  
  // search for and play a sound file; the lookup path is defined by macOS
  $.NSSound.soundNamed('Glass').play

I don’t think the marginal utility of doubling computing will diminish any time soon. As we gain more computing power, we just start doing more and more computation heavy tasks that weren’t possible before. For example, VR games are notoriously demanding on today’s hardware, especially if you want to put that hardware in the headset. And many applications get slower over time, not faster, as new features are added. T…

Also old programs had to hyoeroptimize because it either is that or it's too slow. Today the speed of the computer makes it incredibly forgiving.

One of my fav macOS apps is iStat. It lets you keep track of all types of stuff from the menu bar... https://bjango.com/mac/istatmenus/

Or for the free open source equivalent, I like and use Stats:

(Though I really wish it had a more Googleable name...)

Anecdotally, the M1 feels very performant with 8gb (I have MBP and Mini 8gb variants) compared to my 16gb Intel MBP and my 32gb Hackintosh. That said - it’s not magic. 30 tabs in Chrome is a lot if you’re not using a tab suspender extension. But one thing I do notice is that when a Rosetta 2 app is running, the entire machine seems to take a hit. I would check the architecture of your apps and see if you have any x86…

Lol 30 tabs is a lot? I'm running 32 gb ram on windows i7-6700 3.4 ghz on mini ATX and currently have 883 tabs open, using marvelous suspender and few other tweaks, but still have 95 windows opens (1 tab typically alive in each window minimum excluding my suspension blacklist...). Also have photoshop, notion, and a few other apps going and am running smoothly at 40-70% cpu utilization and 85% memory...

Err, same with Android? And every OS ever. That's just standard process isolation. Or am I misunderstanding something?

There’s some deep dive articles on the way the input loop works. But OP is correct, and the reason iOS feels smoother. Android has a lot more UI lag.

I don't think Apple has any special tricks for input loop.

Some Android phones really have input lag, but it is not caused by CPU load. For example, on my phone, there is approximately 100-150 ms lag between tapping the screen and registering the touch. The lag is not caused by CPU load, but by slow touch sensor.

I don't think Apple has any smart code optimization tricks. Either they have a faster touch sensor or just some people believe that if something is made by Apple then it is of a better quality.

Here is a comparison of input lag in games in iOS and Android [1] and it shows similar results: 80 ms between a tap and reaction on screen.

Pre M1, I've always preferred a PC. When I'm using a laptop, especially doing real work, they heat up, the fans go crazy, the laptop is hot to the touch and everything slows down. It almost makes you anxious. You're wondering if it's about to crash or go on fire. I've always kept a Desktop PC on the go for this reason, a well cooled desktop just doesn't have these issues. With a laptop, I always feel like I'm comprom…

I just looked up some benchmarks. Apparently a m1 is 2-4x faster at many tasks than my wife’s gaming desktop from 5 years ago. It’s comparable in many benchmarks to my ryzen cpu as well? What’s the catch?

Most likely her gaming PCs GPU is on par with or exceeds the M1s GPU. That would be the biggest downside in your specific comparison.

You can only use one external monitor

And that's only on the laptops. Two monitors are supported on the Mac Mini.
