Since Catalina I have been getting daily freezes, where the entire operating system locks up. I can still move the cursor around and audio keeps playing as well, but everything else is completely frozen.

I got a similar question earlier, and I think the answer to that one should apply here as well: https://news.ycombinator.com/item?id=23086849

I just had a MBP fixed (it was quick!) due to it swollen up one day. It would not lie down flat on a table and the trackpad was useless. Obviously could not close the screen either. How common is this?

Very. It has happened to me so many times that now whenever I travel I always take a set of pentalobe screwdrivers with me so I can remove the back plate of my MBP when (not if) this happens to avoid structural damage.

There's nothing wrong with throttling in itself. Pretty much anyone will prefer a performance hit to a spontaneous shutdown. Where Apple got in trouble was that they were doing it secretly . Now days they still do the throttling, but you can go into battery status and it tells you if the battery is delivering peak performance or not.

It actually gets worse in Apple's case. They were doing it secretly, which is bad enough, but they were also denying warranty repairs to throttled phones (since policy was to only conduct the repairs once an arbitrary "health" metric fell below a certain point, and the throttling kicked in first). This meant your options were to either deal with the crap performance, or void your warranty by installing a third party…

> "your options were to either deal with the crap performance, or void your warranty by installing a third party battery."

Or pay Apple a not-entirely-unreasonable fee to get them to replace the battery ($49 IIRC?), a bit more than the third party price but perhaps worth it for peace of mind.

Oh damnit, damnit. I've been having those on 10.15.4 too, was really hoping they'd fixed it on this one. It's really profoundly upsetting to spend $3,500 on a brand new computer by the most reliable major manufacturer in the industry and still have daily damn kernel panics.

> by the most reliable major manufacturer in the industry You might want to revisit that. If you are looking for reliability, ThinkPads are way better.

Also a product long past it’s glory days. Ditched my less than year old X1 Carbon to get a 16” MacBook Pro because it was randomly dying while purporting to have 25% battery left.

I don't even let my screens turn off anymore; these days I get this weird thing where after waking the monitors up the monitor does not get a signal, but if it is plugged in, the mouse jumps around at like 2fps on the main display as if there's some weird interrupt denial of service going on. To fix this, I have to restart just to use my monitor again.

External display wakeup problems have been an issue on many generations of MacBook Pro going back to PowerBooks (even with Apple displays). Very annoying!

I experienced this issue using an HDMI to DVI adapter from my 2018 Mac mini to a Dell Ultrasharp display. After purchasing a replacement cable that didn't remedy the problem, I discovered that it's a known issue.

The fix was to use a USB-C -> DisplayPort cable (using DisplayPort via USB-C alternative mode). It appears that the HDMI port can't be used with a DVI converter. DVI ports have been replaced by DisplayPort, HDMI, and DisplayPort for some time but it was still a disappointment.

This is an admission that their upgrade rates for Catalina are bad. Between the now-customary list of new bugs and the 32bit massacre, the Vista comparison clearly struck a chord. It would have been so much easier to just keep shipping the 32bit compat layer.

If MS wanted to kick Apple in the shins they should get the Github Actions runner to support Mojave (right now it only supports Catalina). Would help me stave off upgrading myself and users for a few more months.

It's crazy that even dot releases are a full 3.6G download

I "asked HN" about this recently but unfortunately it has not received much attention. Maybe now there are people around who know what exactly happens during an update? https://news.ycombinator.com/item?id=22688198

Not an expert in how the update process works, but the update certainly contains all the changed files, of which there is usually a lot. (I would think this is every project that has had a source code change internally…) There are number of shared- and kext-cache related things that also run afterwards.

Looking forward to seeing whether this contains a microcode or OS patch to fix what appears to be an Ice Lake CPU bug: https://youtrack.jetbrains.com/issue/JBR-2310 Read the whole thing. It really appears as if there is a virtualization-escaping CPU-crashing bug in Ice Lake (10th generation) Intel chips that was discovered because it exclusively crashes when used with Jetbrains IDEs. Sounds unlikely, yes, but serious…

Self-reply: no, it apparently does not. Microcode rev is the same and the issue is still there.

TL;DR: Jetbrains IDEs all crash on the 2020 Air, which has a 10th gen Ice Lake CPU in it. Sometimes it brings down the OS. Doesn't happen at all on older Macs. At first I and everyone else thought it was a MacOS or maybe graphics driver bug.

Then the plot thickened...

I tried it in a Parallels Linux VM, and it crashed and brought down the entire host. Not the VM, the host. This should not be possible.

Then someone reported that it also afflicts a Microsoft Surface model with the same generation CPU.

So given that it escapes VM isolation and occurs on multiple OSes and hardware, it really appears as if this is an Intel CPU bug being triggered by some exotic pattern of instructions being generated by the JVM.

I must also add that nothing else crashes on this machine. Nothing. I've run multiple OSes in concurrent VMs, done heavy work, run GPU stress tests, and it's rock solid... unless I fire up CLion or GoLand... then kaboom.

No I'm not the only reporter. No it's not (insert mundane thing here). Read the whole thread I linked above.

Do macOS users like pain? In a Wired article, Ziff Davis editor Matthew Rothenberg put it plainly:

"It's like a B&D (bondage and dominance) relationship. There needs to a psychosexual analysis of the Mac community."
