So what issues do you have with 10.11? Because I don't see anything to complain about. Then again, I also didn't see anything troubling in 10.10, 10.9 and 10.8, with the exception of their ill-fated transition to a new DNS backend, which they later reverted.
A few bugs here and there, yes. Nothing I haven't seen since 10.2, or that's not comparable to the kind of issues I have with Windows 10 or the Ubuntu box I use for development (actually that's far worse, but I digress).
- UI non-responsiveness: it is extraordinarily frequent that I will chord a tab change in Safari or in iTerm2, and the system will not respond for sometimes multiple seconds. It's the same with creating tabs in Safari. ⌘-t or ⌘-{ do not respond.
- Application switching focus failures: ⌘-tab will raise another window, but window focus will not follow. This has caused me to lose work. ⌘-tab, ⌘-w will sometimes close an iTerm2 tab that's behind the Safari window I'm looking at.
- Mouse pointer lag: Probably related to the input lag above, the trackpad will not respond for multiple seconds after I begin touching it. If I "wake" it with a two-finger scroll, it will often lose half the input and instead click.
- AirPlay stuttering: even two ethernet-wired systems will still lose data between them. It's a crappy experience.
- discoveryd: My Apple TV's network name is currently "Apple TV (5)". Macs sometimes do this too.
- Slow laptop wakeup: I almost always have to tap a keyboard key to wake the display after opening my laptops (MBr and MBPr). Almost always. But not always.
That's just off the top of my head. Many of these have followed me between OS X revisions and different hardware. It amazes me that such bugs stick around.
Then I clicked Chrome in the dock, hit Cmd-Q, and watched Safari disappear while Chrome opened a new window. Guess it's not just you.
Ok, for this I can't say much, because every since 2010 or so I've used Chrome in place of Safari. As for iTerm2, I've tried to switch to it several times over the years (later mostly because of Tmux integration) but always found it to be buggy and reverted to the Terminal.
>Application switching focus failures: ⌘-tab will raise another window, but window focus will not follow. This has caused me to lose work. ⌘-tab, ⌘-w will sometimes close an iTerm2 tab that's behind the Safari window I'm looking at.
Hmm, haven't seen this -- and I use ⌘-tab and the ~ variant heavily.
I have seen lagginess in focus when switching full-screen apps use, and I sometimes start typing before that happens. This got a little better in 10.11 though (either faster focus switch or less transition time).
>- discoveryd: My Apple TV's network name is currently "Apple TV (5)". Macs sometimes do this too.
DNS issues I've had (and mentioned in another comment). They tried a transition to a new DNS backend which was buggy. They reverted back to the old one with 10.11 (or sometime in 10.10.x) though and has been OK since then.
>Slow laptop wakeup: I almost always have to tap a keyboard key to wake the display after opening my laptops (MBr and MBPr). Almost always. But not always.
Do see this from time to time (though it almost always works in my case).
Could be a sensor issue though -- not a software thing (the display up sensor not registering, but tap working ok).
Still a total disregard of Fitt's law. Horribly inconsistent keyboard support. Behaviour that should be trivially configurable seemingly set in stone. Still, I think, impossible to cut a file in Finder. However many shots that take, apple can't get WiFi working properly. The transparency is an abomination.
If you want something more 'big picture', I think all the changes introduced over the lifetime of OSX have been a bit piecemeal with no overall, unifying process. For example, full-screen mode gets bolted on, rather than nicely integrated with other window actions. Notifications blossom into a side panel, but there's an overlap with bouncing icons in the dock. Etc. There are some great ideas there, but we could really do with an OS11 that picks the best ones and presents them together, in a clean interface, in which they all belong.
Well, those are not software quality issues. Some of those are design decisions, and have been with us forever, not random accidents: "Cut", for example, has never been on the Mac. Transparency in 10.11 is so lightweight you don't even notice it -- nothing Vista-like about it.
As for "total disregard of Fitt's law" that's not some decline either, as it's not worse or better than it has ever been in OS X.
>However many shots that take, apple can't get WiFi working properly.
Well, that qualifies as buggy software. But I have to wonder.
I've had an iBook, 2 MacBookPros (1 company issued), an iMac, a MacBook Pro Retina (current), 2 iPads and 2 iPhones thus far. And I've travelled all over the US, Europe and in several parts of Asia. I've never had any trouble with wifi, even to non-chain, el-cheapo motels.
The only offender has been my iPhone(s), which indeed I've not been able to connect to 3-4 places (restaurants etc) while traveling, over many hundreds of locations over 8 years. And I can't even know if it was because of the iPhone crapping out, or they using some crappy, third party router.
So I wonder, what are all those wi-fi issues people mention in forums etc.
