La suppression de Dashboard
Some of those features were an easy fit, but others were very difficult to add to the file system without breaking backwards compatibility. One particularly scary example is the implementation of hard links on HFS+. To keep track of hard links, HFS+ creates a separate file for each hard link inside a hidden directory at the root level of the volume. Hidden directories are kind of creepy to begin with, but the real scare comes when you remember that Time Machine is implemented using hard links to avoid unnecessary data duplication.
Listing the contents of this hidden directory (named "HFS+ Private Data", but with a bunch of non-printing characters preceding the "H") on my Time Machine backup volume reveals that it contains 573,127 files. B-trees or no b-trees, over half a million files in a single directory makes me nervous.
That feeling is compounded by the most glaring omission in HFS+—and, to be fair, many other file systems as well. HFS+ does not concern itself with data integrity. The underlying hardware is trusted implicitly. If a few bits or bytes get flipped one way or the other by the hardware, HFS+ won't notice. This applies to both metadata and the file data itself.
Data corruption in file system metadata structures can render a directory or an entire disk unreadable. (For a double-whammy, think about corruption that affects the "HFS+ Private Data" directory where every single hard link file on a Time Machine volume is stored.) Corruption in file data is arguably worse because it's much more likely to go undetected. Over time, it can propagate into all your backups. When it's finally discovered, perhaps years later when looking at old baby pictures, it's too late to do anything about it.

Chanceux. Un des rares. Mon iMac Retina à moi pédale dans le beurre, c'est l'enfer, même avec toutes les clean install et mise à jour. Yosemite, une pourriture maudite, et iMac Retina, une machine pas si point du tout, avec un très bel écran mais sorti trop viteJ'ai un iMac Retina, pas de soucis particulier. Peut être est ce la seule machine vraiment au top avec ce systeme, vu que les deux sont sortis ensemble?
