Mac Os X For Intel X86

admin



A community of users running Mac OS X on x86 hardware. Mac OS X 10.7 'Lion' was the first version of OS X to drop support for 32-bit Intel processors and run exclusively on 64-bit Intel CPUs. The server edition, OS X Server, was architecturally identical to its desktop counterpart, and included tools to facilitate management of workgroups of OS X machines, and to provide network services. System calls aren't considered a stable API on Mac OS X; instead, you always go through libSystem. That will ensure you're writing code that's portable from one release of the OS to the next. Finally, keep in mind that Mac OS X runs across a pretty wide array of hardware - everything from the 32-bit Core Single through the high-end quad-core Xeon.

3. The microarchitecture of Intel, AMD and VIA CPUs: An optimization guide for assembly programmers and compiler makers
This manual contains details about the internal working of various microprocessors from Intel, AMD and VIA. Topics include: Out-of-order execution, register renaming, pipeline structure, execution unit organization and branch prediction algorithms for each type of microprocessor. Describes many details that cannot be found in manuals from microprocessor vendors or anywhere else. The information is based on my own research and measurements rather than on official sources. This information will be useful to programmers who want to make CPU-specific optimizations as well as to compiler makers and students of microarchitecture.

5. Calling conventions for different C++ compilers and operating systems
This document contains details about data representation, function calling conventions, register usage conventions, name mangling schemes, etc. for many different C++ compilers and operating systems. Discusses compatibilities and incompatibilities between different C++ compilers. Includes information that is not covered by the official Application Binary Interface standards (ABI's). The information provided here is based on my own research and therefore descriptive rather than normative. Intended as a source of reference for programmers who want to make function libraries compatible with multiple compilers or operating systems and for makers of compilers and other development tools who want their tools to be compatible with existing tools.

ForwardCom: An open standard instruction set for high performance microprocessors

This is a proposal and discussion of how an ideal instruction set architecture can be constructed. The proposed instruction set combines the best from the RISC and CISC principles to produce a flexible, consistent, modular, orthogonal, scalable and expansible instruction set for high performance microprocessors and large vector processors.

The ForwardCom instruction set has variable-length vector registers and a special addressing mode that allows the software to automatically adapt to different microprocessors with different maximum vector lengths and make efficient loops through arrays regardless of whether the array size is divisible by the vector length. Standardization of the corresponding ecosystem of ABI standards, function libraries, compilers, etc. makes it possible to combine different programming languages in the same program.

Test programs for measuring clock cycles and performance monitoring

Test programs that I have used for my research. Can measure clock cycles and performance monitor counters such as cache misses, branch mispredictions, resource stalls etc. in a small piece of code in C, C++ or assembly. Can also set up performance monitor counters for reading inside another program. Supports Windows and Linux, 32 and 64 bit mode, multiple threads.

For experts only. Useful for analyzing small pieces of code but not for profiling a whole program.

  • This version of Mac comes with an interesting feature called time machine. It allows the user to back up the deleted or replaced by another version of the file. Time machine does not make bootable copies of backed up the volume, it does not backup encrypted FileVault home dictionary until the user logout. It also does not back up to Airport Disc hard drives but this issue is been resolved on March 19, 2008 update.
  • It doesn’t the support classic application.
  • It comes with a total of 18 languages.
  • It comes with Alexa voice to voice over and the Apple company assured that it is the most natural and understandable voice yet.
  • A quick look is available which allows us to view the document without opening them in external software.
  • An updated version of photo booth is introduced which allow us, user, to record video with real-time filter and blue/ green screen technology.
  • It offers Objective-C 2.0 runtime, which has new features such as garbage collection

System requirements for this new version for Mac OS

To enjoy this version of Mac OS X, there are some basic requirements for a system like:

  • If we are talking about the processor then we need an Intel processor or PowerPC of G5 or G4 (867 MHz and faster).
  • The DVD drive, internal or external for installation of the operating system.
  • Minimum of 512MB of RAM is required for the proper functioning of the system. Additional of 1Gb of is recommended for development purpose.
  • Minimum of 9 GB of the disc is required.

These are the features required for the general purpose.

For some features specific requirements in the Mac are :

  • Time machine application needs an additional hard drive.
  • For boot camp, a Mac with Intel processor and Windows XP service pack 2 or Windows Vista is required.
  • 1.8GHz PowerPC G5 is required for the DVD player for improved de-interlacing.
  • An insight camera (external or built-in), USB video class camera or Firewire DV camcorder, an Intel or PowerPC G5 processor is required for the photo booth.

To get this latest version of Mac

If we set our mind to upgrade our Mac with latest features then we have to upgrade our pc with Leopard 10.5. The ISO file is available on the official website as well as on the apple store. We have to decide what type of installation we require because it comes with three types of installation: Upgrade, Archive and Install, Erase and install.

Archive and install take the middle ground method. This installer moves all your data in one folder and then create a clean installation of OS X 10.5 Leopard. This method allows the user to get all their existing data including the user account. Installation of Leopard OS in the Mac, you have to boot from the Leopard install DVD.

Installation process step by step:

  • First, we have to insert the OS X Leopard install DVD into Mac DVD drive.
  • After that an install Mac OS X on display on the screen and we have to double click it.
  • Click the restart button when the install Mac OS X open.
  • Enter the administrator password and press the OK button.
  • Mac will restart and boot from the installation DVD. Restarting from the DVD take some time, so be patient.

How To Get Mac OS Leopard on your Mac

Snow leopard comes with no option other than upgrade, but with few extra steps, we can perform erase and install. The ISO file is available at the Apple official website and also on apple store. For installation, there are some system requirements like

  • An Intel Mac because it doesn’t support older PowerPC Macs.
  • At Least 1GB of Ram is required to run the Snow Leopard.
  • It requires 5GB of free space for installation in the system.
  • A DVD drive is also required.

After gathering all the requirement, now it’s time to install the Snow Leopard in PC

  • Prepare the PC for installation like backup data, repair drive errors and disc permission.
  • Insert the Snow Leopard install DVD into the DVD drive.
  • Then after double click the install ‘Mac OS X’ icon.
  • Click the continue button after opening the Mac OS X Installer.
  • Select the drive which has already OS X 10.5 installed.
  • Click the customize button if we want to change anything to package.
  • When we are ready to install with default application then click the install button.
  • Enter the password and click the ‘OK’ button.
  • Copy the core file and restart.
