I was bitten by this this week. Tried to reuse my installer to install OS X El Capitan on a MBP without redownloading it over my super-fast 2Mbps internet connection. First, I try to install it by just copying the installer app - "can't be verified". Then I make a bootable USB stick using DiskMaker X - "can't be verified". I run an integrity check on the installer - all good. I then try running `/path/to/Install\ OS\…

super-fast 2Mbps internet connection Don't complain. Even with torrents and 100Mbps fiber, we max out at 1MB/sec here. It reportedly costs 20,000CNY/month (~USD$4500) for an uninhibited 512k connection out of mainland China, if you can get it. (You generally can't.)

Not that that isn't awful, but 2Mbps is 4 times slower than 1MB/s...

This is not related to their release schedule, it has to do with the certificates used to validate software. You can view an explanation of application level code signing here [0] and the concepts also apply to signing OS images. [0] https://developer.apple.com/library/mac/documentation/Securi...

I believe they're saying that it is related to Apple's release schedule because having a hard deadline every year and a fixed feature set for that hard deadline means that you run into problems with quality. I would dearly love for Apple to take a year or two (or, hell, five, I'm happy with the current feature set) and just fix bugs. No new features, just bugs. Do another Snow Leopard release, or three.

I don't know Tim Cook, but I don't think anything will get better under his watch. Certainly, people grow, but his background has been as a "make the trains run on time" kind of guy. So that's probably what he most cares about.

Here are some of his previous jobs[1]:

- 12 years in IBM's personal computer business, ultimately serving as the director of North American fulfillment

- vice president for corporate materials at Compaq

- closed factories and warehouses, replacing them with contract manufacturers

- advance investment in flash memory from 2005 onwards, guaranteeing stable supply

A logical extension of stuff like "fulfillment", "corporate materials", and "stable supply" would be: "release new software on a regular basis". No?

Still, what is the commercial alternative? Win 10? Not for me!

I had a handful of apps I use all the time stop working entirely about a week ago. They were purchased from the App Store but are no longer in the App Store. I am furious. I am willing to bet the expired certificate is the culprit.

> I've had to carefully maintain the .app's myself across a couple Mac's as Apple stopped letting you download things that are no longer in the store. Since when? I always download .dmg's and install them outside of the Apple Store. You have to do this roundabout security measure in Preferences to run them, but they're always runnable...

The whole "old installer" and "bootable disk" has been a pain-point since 10.8 for me. I have done 4 or 5 clean installs for friends in the last 6 months, and I tried to make a 10.10 or 10.11 bootable USB... no go - each time, a new issue. I have ended up every time using my older 10.8 (ML) install USB every time, then just firing off the free App Store upgrade to 10.11.

In newer Mac's (2012 onward IIRC) you can just boot into a net installer, and it goes and fetches the installer from the internet before re-installing.

But if you quickly use sudo .../createinstallmedia to make a bootable usb installer from your annoyingly re-downloaded App store installer, you should be safe from this, shouldn't you? That's what I did when I installed, but I haven't tried to use my usb installer, so I suppose it could have expired too. (edit) Sigh, yes, expired also. Re-downloading...

It uses trusted timestamping servers run by certificate authorities to sign the timestamp information.

Ok, I didn't realize that. But it still doesn't solve the problem of compromising an old certificate and creating a fake signature with your own time.

Expired and compromised are two different things. If compromised, it will be published in a CRL with a reason flag.

Changing the date in the system (and disabling network time) worked well. A quick search led me to this solution, avoiding the whole re-download to please the sentient dictatorial master.

I go back to the days of System Bombs and Unimplemented Trap errors. It was maddening.

Ahh the bomb, a great (Susan Kare) icon: https://en.m.wikipedia.org/wiki/Bomb_(icon) MacsBug was an essential utility back in those days.

I never got around to learning to use MacsBug.

I just stopped running applications that caused too many crashes.

I miss those days dearly. I LOVED being a Mac user during the 1990s.
