Not familiar with actual Macs, but I did install OS X plenty of times on PCs. Can't you just change time on your machine, install it and then change it back? I'm sure OS X can be installed offline.
The article mentions this as a solution, yes.

Re: Previously Downloaded OS X Installers No Longer Work
#12Apple has been getting sloppier and sloppier over the past 5 years or so. For instance, even if you have selected "automatically set my timezone based on my location", it won't update unless you actually open the date/time preferences panel every time you change zones.
worked for me flying from uk to mainland europe, and back.

#13Under windows, when I sign a binary, I also have the option (well - it's more like a strong recommendation) to time-stamp the signature.
That way, windows can check whether the signature was made during a time when the certificate was valid. This means that when your certificate expires, you won't be able to sign new binaries, but at least the existing ones continue to work.
This is something Apple should really consider implementing - even just for the sake of archival of old OS versions that people might still want to install for nostalgias sake.

#14Completely by-the-by, but I couldn't help but notice the small advertisement at the bottom for Smile PDFPen[0]. I'm using uBlock Origin, but this wasn't blocked by it, presumably because it's unique to this site, and is indistinguishable from the rest of the content. However, it's very unobtrusive, doesn't track me at all and has no influence on the actual content of the article, so I have no problems with it being here.
This makes me wonder if there could be a set of guidelines that could be formulated for acceptable advertising on websites...?

How is this relevant?

Does Microsoft co-sign the binary or something? If not that feature seems like it would defeat the purpose of expiring certificates.

#17I 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\…
Apple is just awful about providing meaningful, useful errors. The worst is AirPlay. When it fails to connect, which is about 33% of the time, there's nothing. It doesn't even pop up a generic alert, it just silently (or not so silently, if you're playing music) reverts to local playback.
Many other examples abound. Most errors at least provide a message, but one so generic as to be useless.

How does this help? In order to provide any security you would need to limit the time from signing, which would be very similar to just issuing the certificate for that much longer. There is no way to verify that the binary was actually signed at that time.

#19It kinda seems like Apple has set out to prove that having a release schedule that is date and feature driven at the same time is not a good idea.
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.

Encountered the exact same issue. But all kind of weird bugs turned up in the older version of App Store, to the point where I had to re-format the drive. And the Apple forums are absolutely no help. took me 3 hours to do something that should have been trivial..
