I had a different glitch but this reminded me. I have a 2017 Macbook Pro. About a week ago, the left speaker randomly started blasting odd rhythmic white noise. It stopped after a few seconds, but it appears to have blown the left speaker. I've no idea if this is common, or how to prove it and get a new one, or if I even care to go through the hassle.

Thought this was regarding Macbook Pro speakers being blown out due to audio glitches that was reported last week: https://www.dpreview.com/news/2610969677/some-macbook-pro-ow... (RIP my 2018 Macbook Pro speakers, they sounded great when they worked)

I think I got bit by that last night - working with sound in Mathematica, a simple MIDI tune was playing and then my MBP made a horrendously loud noise. Didn't damage the speakers, which surprised me given how loud it was. Probably the fastest I've mashed CMD-Q to quit a program though.

I'm curious... since it seems like a number of high-profile bugs often tend to be with clock- or date-related things... is there a set of best practices somewhere around creating time-related tests? A complete list of situations to test under?

I'll confess that testing that my software works while a user (or daemon) changes the system clock is something that I don't think has ever occurred to me, and now I'm wondering what other edge cases also haven't occurred to me.

That's a weird glitch, and generally I'm not a fan of apple hardware (I think it's overpriced, that their keyboards suck, that they don't have enough ports, and I don't enjoy working in osx), but this article comes off as almost biblically haughty. Apple should have tests around clock updates affecting external audio quality? I mean, maybe after this bug being discovered, sure, but before, was that a connection that could have been made in a QA engineers mind? Maybe it is, maybe it's fair? I don't know anything about manufacturing hardware, but I just find it surprising.

Like, off the top of my head, the x1 carbon is still loved by most Linux users (that I have encountered) despite the fact that out of the box, sleep literally does not work on it for Linux systems. You have to install a BIOS update. Yet Lenovo doesn't seem to get nearly the attention that apple does for this and the myriad of other mistakes I have discovered with them.

I hope that fix mentioned works! I just changed the time setting now.

I use an iMac pro, I’ve definitely noticed it over the last few weeks, typically when several chrome tabs are open or heavy use it seems. I also noticed it pretty bad when using a Universal Audio Arrow device, and web midi also.

Currently I close chrome and reopen to fix. Happens every 1-2 days.

This happened to me as well a few weeks ago. Same model MBP. Left speaker got blown out. Haven't had time to take it in to Apple yet (my right hand USB-C ports are also dead so I'm overdue anyway). Googling it, it seems we're not alone
