August 30, 1990: A 112-page confidential Apple memo lays out what the company must do to make the Macintosh division a marketplace contender.

The internal memo comes from Dan Eilers, Apple’s vice president of strategy and corporate development. He boldly says Apple must consider four strategies: licensing Mac OS, licensing both the Mac’s operating system and hardware, creating a spinoff brand for the Macintosh, or starting a totally new company to combat the growing threat of Microsoft’s Windows.

August 5, 1997: Apple gets into a standoff with Power Computing, a maker of Macintosh clones. It marks the beginning of the end for Apple’s mid-’90s strategy of licensing the Mac operating system.

“If the [Mac] platform goes closed, it is over,” predicts Power Computing CEO Joel J. Kocher of Apple’s strategy. “[It’s] total destruction. The kiss of death.” Of course, things don’t turn out exactly like that for Apple…

April 27, 2008: Psystar’s first Mac clones ship to customers. The new Open Computer means that, for the first time since the mid-1990s, there’s no need to assemble a “hackintosh” to run OS X on a non-Apple computer.

Unlike previous clone Macs, however, these low-priced computers don’t come with Cupertino’s blessing. Naturally, a fight ensues.

March 27, 1995: The first official Macintosh clone launches, as Radius releases its high-end System 100 Mac.

Made by a company founded by several notable Macintosh alumni, this marvelous machine kicks off the era of clone Macs in grand fashion — before things take a turn for the worse.

January 31, 1998: Mac clone-maker Power Computing goes out of business, having auctioned off its office supplies and computers.

Apple bought out Power Computing, once the fastest-growing PC company of the decade, the previous year. As a result, Power Computing shareholders receive Apple stock as a replacement. As it turns out, that may not have been a terrible deal.

January 4, 1995: Apple signs a deal with third-party Mac accessory-maker Radius, allowing the company to build Macintosh clones.

Radius is the second company to license the Macintosh operating system. (Power Computing did the same thing a month earlier.) However, Radius will become the first licensee to bring a clone to market when its System 100 ships in March 1995.

The new 11.6-inch MacBook Air is extremely netbook-like in dimensions, if not in specs or price, but if that $999 tag doesn’t do it for you, the gadget sweatshops of China would be happy to sell you a Hackintoshable MacBook Air clone for just $260, right down to the official Apple logo.

We posted yesterday that Apple and Psystar had reached a partial settlement in their age-old legal conflict over Psystar’s manufacturing and marketing of PCs with OS X pre-installed. The only thing up in the air was exactly how much those Hackintoshing upstarts from Florida would end up having to pay.

Now the number’s out, and it’s not pretty: Psystar has agreed to pay Apple $2.67 million dollars in damages.
