Low power makes it widely available for laptops and handheld devices, as well as high density storage, servers (such as blade centers). 64-bit processing capability, single instruction multiple data flow design makes it more suitable for multimedia, graphics processing. Apple's desktops, Xserve servers, and other graphics and networking devices are using this processor. Apple Xserve G5, for ex

It is best to comment out the first line because it will use the Home directory of each user as the AFP directory, which will disturb the files in our Home directory. The key point is "options: tm". This option is actually used to make netatalk act as a Time Machine server.

Xcode will give you the ability to create applications such as computing and rendering engines that use a 64-bit memory addressable. This is ideal for applications in datasets that run faster than disk access by accessing data in memory. Xcode will provide you with the tools to build and debug 32 or 64-bit applications for Intel Core i5, i7, and Mac OS X Lion, and to create Fat Binaries with 32-bit and 64-bit execu
Depending on the release notes of the OS X 10.9 Mavericks developer preview, Mac computers that support the current OS X 10.8 mountain lion can support OS X Mavericks. On yesterday's WWDC, Apple did not show which Macs could run the next generation OS X system. Mac computers that specifically support OS X Mavericks include:
IMAC (Models in mid or later 2007)
MacBook (aluminum model in late 2008, early 2009 or later)
Macbookpro (Models in mid/late 2007 or later)
