@DavidCarlisle well if fails simply because \ref is robust, so Frank will perhaps break it anyway. And if the kernel had sensible hooks hyperref would perhaps not have to redefine it. So we could blame Frank ;-)
@DavidPurton Using the app Digital Colour Meter, which I think is an Apple provided app despite the “u” in the name, I find R=255, G=255 and B=254. So yes, it's off white. And if I remove [cmyk], it becomes all white.
@DavidPurton Conversion from cmyk to rgb is not very precise with xcolor. I get the same as @HaraldHanche-Olsen, but on my system the app is “Digital Color Meter”.
@egreg The PDF is fine inside. And no problem with Adobe Reader. It's odd that Preview only has problems sometimes. I can reproduce it with just an empty white tikz node too. Perhaps it's just a Preview bug. But it's annoying, since it shows up when printing!
@HaraldHanche-Olsen OK. It must be a general CMYK white issue then, I just didn't notice it with plain text. It's OK that the black isn't black. CMYK 100% K is not the darkest colour that can be printed, so when it gets transformed to RGB via colour profiles it is meant to come out a bit grey. But the whole point of CMYK white is that there is no ink, so you should get the same colour as the page, but this isn't happening.

_kMDItemDisplayNameWithExtensions = "Digital Colour Meter.app"
kMDItemAlternateNames = (

)
[… and so on …]
@egreg ↑↑↑ They cheated with the name
@DavidPurton It's just too bad we can't blame @UlrikeFischer for this one.
Gosh, Preview is worse than useless. (My Linux system suffered catastrophic filesystem corruption, sadly, and I'm stuck with Mac OS until a rebuild things sob). Even though I have a PostScript Printer and PostScript driver installed, it's unable to even print the CMYK black as black! It comes out dark purple…
Actually, maybe I shouldn't be too critical. I think it's a CUPS problem. It uses a PDF workflow which transforms everything through RGB colour space :(. Linux does this too unless I use a PostScript workflow.
@FaheemMitha Yes, Adobe Reader outputs PostScript directly and bypasses the CUPS PDF workflow. I can also use pdf2ps and print the PostScript file directly.
@FaheemMitha It's the second time it's done it actually. I suspect it's due to poor support for Mac hardware. Things have been getting hard to make work with every Linux kernel upgrade and every Mac OS upgrade. It's old hardware now and if it runs out of memory and tends to die and I have to power it off. Sometimes it doesn't make it back...
The first time I lost my system partition, so not so bad. But this time, I lost my data partition. After a manual fsck and repair, I was left with 100000 files and directories in lost and found called #XXXXXXXX :(
And I didn't have a back up for a couple of months :(. Just spent two days trawling though and recovering things. But got just about everything back, which is a plus.
It corrupted so badly that it wouldn't even boot to Mac OS! I had to reinstall that too :(. Oh well. I just bought a new computer.
My MacBook Air is old and nearing the end of its useful life anyway
@DavidPurton Oh, you're running Linux on an Apple machine? What distribution?
I personally don't think Apple machines make much sense. They're expensive, and they're basically locked, as I understand it. So you can't make changes as you want.
@FaheemMitha I think it's more accurate to say that it's more closed, in the sense of closed source – which means it can be harder to figure out why things go wrong when they do. Yes, it is also more locked down, but you can disable most of the protections either temporarily or permanantly if you need to make changes the system normally won't allow. Expensive: Yes.
@HaraldHanche-Olsen, @FaheemMitha, no I run Debian dual boot. No VM. At the time I bought it more than five years ago it was the best value Ultrabook around. It's mostly worked well. But I admit that getting it to dual boot is a real pain.
I getting a ThinkPad this time round. I was tempted by the Dell XPS 13, but it's a fair bit more expensive than the ThinkPad X390 for similar specs. If not as pretty.
@HaraldHanche-Olsen It's a different case for the current Macs. It's currently much too hard to run Linux on them. Too much hardware isn't supported.
@FaheemMitha Oh. Yes, that is a problem. Upgrades are near impossible, which is why I tend to max out my macs when I buy them. Everything except the CPU. For me, it's not worth a small fortune to get a marginally faster CPU.
@HaraldHanche-Olsen Personally, I don't think Apple's products make much sense, which is why I don't buy them. Well, except for a IPod in 2007, which died fairly quickly.
But there seems to be kind of a fetish surrounding them, for some reason.
A different problem when trying to build a PC, which I'm facing now, is that there are so many choices they are bewildering. Plus, having to worry about Linux compatibility.
And it's often not clear what the good hardware is.
@FaheemMitha Well, over the years I have used MS-DOS, MacOS (before OS X), Domain/OS, FreeBSD, Linux (Ubuntu), and finally OS X / MacOS. I've had problems with every one of them. MacOS has given me loads of headaches too, but by and large, I find it sucks a bit less than the others. But of course, what makes sense to you depend on many things: Your computing needs, your economy, your time, and your competence in dealing with problems among thiem. …
… I find that the older I get, the more willing I am to spend money in order to waste less time. (But when I retire, I will have less money and more time, so this may change.)
Yes, It's a good day! I had a very odd error ('Command \sidewaysfigure already defined.') last week after updating all packages of my MacTex installation. If prevented me to use the [newfloat=true] option for minted package. Now, after updating all packages again, the error is gone.
