This is an old question, but just in case someone stumbles on it and is specifically worried about the privacy implications of Notification Center, the answer is YES, OS X does keep a log of notifications on disk. The format is an sqlite database, and it can be found inside this folder: /Library/Application Support/NotificationCenter.
fixed Mac OS X users lost administrator access. Posted on.Filed under: Technology Tags: mac So several people are reporting trouble with Leopard when after upgrading or e.g. Shutting down by just holding the power button all users have lost administrator access they might have had before. Random Access Memory is a temporary storage medium that your Mac's CPU uses for fast access to data it's processing. The CPU can access data contained in RAM much faster than it can data held on.

Now click the menu marked ‘Utilities' and choose ‘Terminal' and a terminal window will open. On your terminal type 'csrutil status'.

Note: HFS is not supported in Mac OS X.
HFS (Hierarchical File System), also known as the Macintosh StandardFormat, is a volume format introduced in 1985 to replace MFS(Macintosh Filing System). Unlike MFS, which was designed for the 400kilobyte (KB) floppy disks used in the Macintosh 128K and 512K models,HFS supports a directory (i.e., folder) tree and much larger volumes(i.e., disk partitions or drives). Each folder may contain up to32,767 files; volumes on recent OS versions and computer models may beup to two terabytes (TB). Files may be as large as twogigabytes (GB) in size.
There are two kinds of blocks on an HFS volume: logical andallocation. Logical blocks, the basic storage units of a drive, arealways 512 bytes. The size of an allocation block (whichconsists of one or more logical blocks) depends on the size of thevolume. Because HFS uses a 16-bit address to store and locate data,regardless of its size, a volume cannot have more than 65,356allocation blocks. This has two ramifications:
- An allocation block can store information for only one file, sothe absolute maximum number of files on a volume is 65,356.
- The larger a volume is, the larger its minimum file size will be.
To determine the allocation block size of a volume, and thus itsminimum file size, use this formula:

In this case, no matter how small a file is, it will always beallocated at least 16KB of space. As a general rule, large HFSvolumes, especially if they contain numerous small files, accumulatemany wasted logical blocks. For this reason, Apple developed HFS+, amore advanced disk format compatible with Mac OS 8.1 andhigher.
