Mac OS X Tiger Released and Analyzed
bonch writes "Ars Technica has gone under the hood of the Tiger release and offers up detailed impressions on the new OS X update. The review covers everything from interface changes, new kernel updates and programming interfaces, the unification of UNIX system startup services into one service called 'launchd', the return of metadata, to the fact Apple has announced that from 10.4 forward there will be no more API changes. A fascinating read about the technical details behind Tiger and the specific changes that have occurred since Panther's release 18 months ago." Today is the update's official launch day, though some lucky people have had it for a few days already.
Another in-depth review, focusing more on features and less on the OS's underbelly is over at MacInTouch... http://www.macintouch.com/tigerreview/index.shtml
If it's your whole machine that's crashing (i.e. kernel panic) then look to bad or under-spec RAM first, not the OS. OS X machines are very particular about RAM.
Damn those pesky terrorists

I got my copy of Tiger yesterday, so I installed it last night. Dashboard is cool, where I spent way too long adding and removing widgets just so I could watch the ripple effect (I've got a 1.5 GHz PowerBook G4 17" with 1 GB RAM). It's kind of like when everyone spent about 30 minutes doing the Genie effect when they got Mac OS X 10.0 Beta. Random cool things:
1. When it's sunny outside, the sun from the Weather widget spills out above it, gently illuminating the other things on the desktop. That's cool
2. The Address Book widget is fast and makes AddressBook far more usable. Just type in a name, and boom! you have their info.
3. The Calendar widget is next to useless. I thought it would show me my iCal events for the day or something, but no such luck. It just sits there, red and unaware.
4. I find this hard to believe but QuickTime 7 looks much better than QuickTime 6. I watched the large Star Wars Episode III trailer in it, and it appears to look far more detailed! You can actually see Anakin's complexion turning gray when he's talking to Palpatine!
5. Spotlight is really cool. It took about 30 minutes to index, but once it was done. I searched on a few terms. It found emails I wrote six years ago that I forgot I received. It's very fast. Type in someone's name, and in one second, you can see all sorts of stuff about them on your hard drive. Basically, your Mac turns into a giant contact manager (if you've ever gotten one of those PIMs to work where it tracked files, emails, and whatever for contacts). I'm getting used to the idea of using SpotLight to look for a file or application before I even go to the Finder, and it works well. SpotLight has earned its place in a hallowed corner place on the screen.
6. iChat can now display what song you're listening to in iTunes. That's cool, too!
7. The mouse preferences has a place to adjust the sensitivity of the scroll wheel and which to make the primary mouse button (left or right).
8. When Safari can't open a page (like this Ars-Technica page right now), it displays an error page, rather than a slide down dialog box. It's less obtrusive this way.
Insert simplistic political, ideological, or personal proselytization here.
The advantages of this approach are the following:
- All those daemon have shared functionality but different code, this means more code to maintain and more security risks (all those daemon have to run at some point as root). Each of the 'old' daemon also has a different file format, which does not make life easier either.
- Process launch criteria can be a mix of those offered by the 'old' daemons, crond is based on time, inetd on network connections, initd on boot sequence. Launchd 'understands" all those notions.
The example I was given was of starting a backup task on a laptop. The criteria to launch the task would be something like if last execution was more than X days ago and the computer is not running on battery power and there is a network connection and CPU load has been low for some time then launch... Launchd is supposed to have 'adapters' to understand the old file formats.Personally I think this is a good idea, factoring out common functionality and using more reasonable file formats, but of course the old guard will complain that the current set of daemon just works (not on a laptop) and that this was proposed by people who do not understand Unix - who is this Jordan Hubbard anyway? :-)
