OSx86 (from the names OS X and x86) is a collaborative hacking project to run the operating system on non-Apple personal computers with x86 architecture on x86-64 processors. The effort started soon after the June 2005 Worldwide Developers Conference announcement that Apple would be moving its personal computers from PowerPC to Intel microprocessors. A computer built to run this type of is also known as a Hackintosh, from the word "hack" and the name of Apple's main model of computers, Macintosh. Hackintoshed notebook computers are also called "Hackbooks".〔 (【引用サイトリンク】title=What is Hackintosh - For Beginners and Noobs )〕 The Apple software license does not allow to be used on a computer that is not "Apple-branded". The legality of this form of tying is disputed by companies such as Psystar, Bizon computer, PearC and MacPC who have attempted to release products using Mac OS on non-Apple machines. However, while the methods Apple uses to prevent from being installed on non-Apple hardware are protected from commercial circumvention in the United States by the Digital Millennium Copyright Act (DMCA), specific changes to the law regarding the concept of jailbreaking has thrown such and similar circumvention methods into a grey area when carried out by end-users for personal use. ==Legal issues and Apple objections== Apple does not authorize the use of the Mac OS on any x86 PC other than the ones it has developed itself. The company used technical means (although not the Trusted Platform Module, or TPM, as has been widely mis-reported〔("'TPM DRM' in Mac OS X: A Myth That Won't Die" )〕), to tie Mac OS to the systems it distributed to developers after announcing its switch to Intel's chips.〔("DMCA axes sites discussing Mac OS for PCs" )〕 The EULA forbids installations of on a "non-Apple-branded computer".〔 On July 3, 2008, Apple filed a lawsuit against Psystar Corporation for violating this restriction, among other claims. Apple claimed Psystar "violated the Digital Millennium Copyright Act (DMCA) by dodging copy-protection technologies Apple uses to protect ." Apple employs technological protection measures that effectively control access to Apple's copyrighted works. Specifically, Apple charged Psystar with acquiring or creating code that "avoids, bypasses, removes, descrambles, decrypts, deactivates or impairs a technological protection measure without Apple's authority for the purpose of gaining unauthorized access to Apple's copyrighted works." This brief revealed that Apple considers the methods that it uses to prevent from being installed on non-Apple hardware to be protected by the Digital Millennium Copyright Act (DMCA). On November 13, 2009, the court granted Apple's motion for summary judgment and found Apple's copyrights were violated as well as the DMCA when Psystar installed Apple's operating system on non-Apple computers. A hearing on remedies was set for December 14.〔 On January 14, 2009, the Gadget Lab site of ''Wired Magazine'' posted a video tutorial for installing on an MSI Wind netbook, but removed it following a complaint from Apple. Textual instructions remain, but include an EULA violation disclaimer. On May 15, 2012, the case Apple vs. Psystar Corporation finally ended. The court ruled that Psystar has "violated Apple's exclusive reproduction right, distribution right, and right to create derivative works.",〔(【引用サイトリンク】title=Court refuses request to review Psystar case )〕 putting an end to the case. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OSx86」の詳細全文を読む スポンサード リンク
