Yeah, it doesn't work, at least on my iMac Pro.

I have missed this chime on my iMac Pro! Makes rebooting into Boot Camp my easier!

While we’re at it, Apple, can we get the sleep indicator light and the battery indicates lights back please?

If I have time I will try myself later on.
 
Worked on my 2019 iMac 27". When I bought it earlier this year I had forgot they remove it so when I turned it on the first time my heart skipped a couple of beats when I didn't hear the chime!
 
They should have just added an option in System Pref to turn it on or off.

Exactly, Apple can be so annoying sometimes...
If you want to have every crap in System Pref, then you feel comfortable with Microsoft.
Apple has cleaned up drastically there so you can find everything quickly.
If you're one of the few people who miss that chime (e.g. at night or in public) hopefully you can handle the keyboard and terminal. The sound has been kept by Apple especially for people like you as part of the system.

Enabled on my 2018 MBP. Doesn’t sound right though, it’s an octave or two lower sound than what I remember from childhood with Mac OS X 10.4 and beyond...

Pretty sure you can, but there is no explicit option for it.
I'll have to experiment but I'm sure I achieved it by adjusting the sound effects part of sys prefs. Playing system sounds through internal and setting volumes down - something like that.
Yeah, there might have been an option by muting the sound before you shutdown your Mac. Something like that, but I do remember it was annoying the hell out of me!

To boot silently, just make sure to mute volume before you shutdown/restart, as waquzy said. Your Mac will retain that state on start up.
 
Of all the somewhat questionable design decisions Apple made with the current generation MacBooks, the lack of a start chime was the biggest head scratcher. Most of the design decisions were geared toward making the computers thinner and lighter - but the no startup chime really seemed like a deliberate attempt at iOSifcation of the MBs (since no iOS device has a startup chime).
 
I can confirm this works on the 2018 Mac Mini as well.

I really missed this and am glad it could be re-enabled, because sometimes my display doesn't pick up the video signal right away (or I boot the machine to remote into it without using a connected display at all) so it was helpful to know that I turned the machine on because otherwise it made no sound at all.

Another big semi-recent one was the removal of Toslink optical support from the audio out on the Macbooks and iMacs. Toslink is the most noise-free, highest quality and lowest latency way to connect your computer to an amplifier. I have a 25 foot toslink cable running from my 2015 iMac to my audio system; if it were analog audio the cable would absolutely pick up hum and interference.

This isn't something that costs a lot; it's just an LED pretty much, yet Apple removed it and now we have to use a USB dongle for Toslink on newer machines, all to save a few pennies.

Apple won't tolerate this for long, look for a firmware update soon to eliminate this workaround.
Apple can really loosen up a little bit and bring the fun back to their products. Everything from Apple today is too clean and sleek. All those little things which made a Mac a Mac are gone and the brand has no more character anymore. Good Ivy is gone. I hope it will change for the better.
 
Agreed, sure, but how about headphone port to the left instead of to the right, and an actual line-input port?

Is there a functional reason the headphone port is better on the left than the right? Well, other than that it would be better for your personal setup?

Actual line-in port? When did that exist? As a former recording engineer, I certainly understand that it can be useful to some users... but not widely/universally useful like a mic-in port for a headset.

The first Mac I used for pro audio production was a Mac Quadra 950. PCs in those days did not have internal DSP, which is essential for digital audio production. The audio workstation software was bundled with NuBus cards with four DSP chips and multiple TOSLINK ports to facilitate simultaneous foreground and background processes. We could then choose our own outboard AD/DA converters (we wouldn't have trusted a PC maker to include a pro-quality AD/DA anyway). That's the way it was in the mid-1990s, and when it comes to pro audio input/output, that's still the way it is today.

Rule number one of affordable computing - put the stuff everyone needs inside the box, put the stuff only a small percentage of users need outside the box.
 
Thanks, but what changes should be made in such file to get the Mac boot chime even after resetting PRAM?

In an earlier post I said...It's been a while since I edited the boot.plist...and...I don't have much free time to test it out (Rebuilding Appt), I will try to find a hole in my busy life to find out, I will report here.
I also do not have a recent Mac, but I don't think that will make a difference, it should mute it even on an older mac if I use the reverse kernel flag.
 
...
However, the latest trick - first shared in the MacRumors Forums by BigMcGuire - appears to have a high success rate, although depending on your Mac model, your mileage may vary.
...

Yes, this NVRAM hack has been confirmed to work on MANY 2016+ Macs running Mojave and Catalina (don't know about other versions of macOS).

But first, this new feature was identified over a month ago, at least. If you want to follow along trying to track down the original source, take a look at this thread:
https://mrmacintosh.com/how-to-enable-the-mac-startup-chime-on-your-2016-macbook-pro/#comment-270

Second, there are few more ways that this can be turned off, following any one of these 3 additional ways:
- in Terminal, type sudo nvram -d StartupMute
- reset PRAM on startup (press and hold CMD (⌘)-OPT(⌥)-P-R on startup) (the chime setting does not survive a PRAM reset)
- turn off and pull plug on desktop Macs (which also resets the PRAM; not all models)

Third, someone posted here that there might be a way to update the boot.plist to make this survive a PRAM/NVRAM reset here:
possibly by by trying to put "... “StartupMute=%00” inside kernel flags. "
If anyone has the know-how and can confirm how to make this happen, please to post over on that thread.

This worked for me. I'm using a 15-inch MacBook Pro 2019. If the volume is up to the max, the sound gets a little washed out. I don't care. The thing that the boot chime always did for me was it let me know that a Mac that I was working on had made it through the power on self test (POST). The chime won't play unless the Mac passes the test. I really don't have a problem with the boot chime being taken away, but this was one use for it.
