Imagine if your next Mac cost you only $300, and ran faster than any G4
or G5 you've ever used.
That future may already be unfolding: Hackers have found a way to bypass
a chip designed to prevent the Mac OS from running on non-Apple PCs,
which are often cheaper than Macs.
Some of the hackers are running the tweaked version of the operating
system on their PCs natively. Others are using the system with VMware,
which allows the Mac OS to support more PC hardware.
Hackers and curious computer users this week have been downloading the
tweaked Mac OS X for PCs, nicknamed "OSx86," from the BitTorrent
file-distribution system.
OSx86 is designed to run on Apple Computer's next generation of
hardware, which some call "MacIntels" and others "MacTels" because the
machines will run on Intel microprocessors rather than the PowerPC
processor used in current Macs. The hacked version of OSx86 is based on
pirated software, which came from copies of the operating system sent to
participants in the Apple Developer Connection. The ADC participants
also received MacIntel computers for testing and development.
Now the hacked version of OSx86 is running on Dell laptops and other PCs
with Intel and AMD microprocessors.
"Mileage varies depending on what kind of hardware you're using, but it
(OSx86) is working on several PCs," said "Mashugly," a college student
majoring in communications who manages the OSx86 Project, a community of
developers interested in the new operating system.
No one knows exactly why OSx86 appears to be running faster on the PCs
than the Mac OS does on today's Macs.
"To be honest, we're not sure," said a hacker nicknamed "cmoski," who
said he works for a large software company. "Some in the Pentium camp
want to say, 'Because a Pentium is faster, of course,' some want to say
(Intel chip architectures are better than Apple's) and some in the
PowerPC camp just want to say that it isn't full OS X (running on the
beta systems)."
The hacked OSx86 bypasses a chip, the Trusted Platform Module, or TPM,
that is intended to prevent the system from running on ordinary PCs.
"We have even gone so far as to remove the TPM kernel extension called
AppleTPMACPI.kext entirely," said cmoski.
The impact of the OSx86 hack on Apple's hardware brand could be severe.
The hack shows that Steve Jobs' company will be turning out machines
indistinguishable from any other PC, or "white box," said German hacker
Michael "mist" Steil.
"Apple wants to avoid the word getting out that (MacIntels) are just
PCs, and that (OSx86) works on PCs," said Steil.
Steil made a name for himself hacking Microsoft's Xbox game console. He
has seen the hacked OSx86 running on a PC, and has been watching the
conversations at the OSx86 Project website. But he said he is not
hacking the operating system himself.
The problem with this hack is that it is based on illegal software,"
said Steil. "You have to start by downloading pirated software."
The hackers are also writing software extensions so they can run their
Wi-Fi cards and other non-Apple gadgets with the Mac OS.
"We have been working on many areas of the operating system," said
cmoski. "Some are working on developing kernel extensions (the OS X
equivalent of drivers) for our favorite hardware. For example, one
driver that I am involved with is for the Broadcom wireless chipset."
Companies such as Microsoft and Intel originally laid the groundwork for
the TPM. The companies insist the chip is meant to verify trusted
computers on a network and prevent malicious code from running on PCs.
Apple would not comment on this story or on its intended uses for the TPM.
But critics have called the TPM an anti-competitive device that stifles
innovation. They suspect the company may use the chip to keep unwanted
third-party software off its machines. Others doubt Apple would take
such a hard line with developers.
"Apple is a better company than Microsoft in general," said Bruce
Schneier, a security expert, author and CTO of Counterpane Internet
Security. "So, it's hard to attribute these nasty motives to them. But
those are the risks."
Microsoft, through its participation in the Trusted Computing Group,
laid the groundwork for the TPM "as a way to shore up its monopoly,"
said Schneier.
Apple could use the TPM, which stores digital encryption keys and
certificates, to block third-party iTunes plug-ins from running on
MacTels. (Apple currently plays a cat-and-mouse game with plug-in
developers by having its software look for known unauthorized code.)
Such a move would help Apple and its partners secure short-term gains in
market share for its iPod, which meshes tightly with iTunes and the
iTunes Music Store.
Apple employees appear to have been trying to listen in on IRC
discussions among OSx86 hackers, according to hackers citing the IP
records from their IRC channels.
The hackers suspect Apple wanted to demonstrate the weaknesses of TPM
security, and may have plans to license its operating system to PC
makers eventually.
"Perhaps Steve Jobs wants to be able to tell Apple shareholders, 'Hey, I
tried,' before he licenses the operating system (to other
manufacturers)," said Mashugly.
It seems like getting around the TPM wasn't that hard, according to a
hacker nicknamed "parch," who said, "Apple could have made the lock
heavier."
I should try it out, I would like apple OS and keep my PC as I can not
afford a Mac, but would like a reliable OS ;)
