At the time of release in January 1985, the Macintosh XL was colloquially referred to as the "Hackintosh", although this name has since been used more generally to describe Macintosh computers assembled from unusual combinations of parts or, after Apple's transition to Intel processors, to denote PCs running OSx86

Upgrades

Because of its roots as a Lisa — and unlike all other Macintosh computers — the Macintosh XL did not use square pixel

History

The re-badging of the XL was a last-ditch effort by Apple to save the poorly selling Lisa which had been usurped by the Macintosh line. After two years of marginal sales Apple was unprepared for the record number of orders placed for the newest member of the Macintosh family.

Discontinued

Despite its relative success, the Macintosh XL was discontinued because it was literally unavailable. Parts had not been ordered to keep the XL in production and once the last of the parts ran out, Apple made the decision to shut down production for good. In 1986, Apple offered all Lisa/XL owners the opportunity to turn in their computer and along with US$1,498.00, and receive in exchange a Macintosh Plus

Sun Remarketing

After Apple dropped the XL from their price list in September 1985, Sun Remarketing of Logan, Utah bought a number of Apple's remaining inventory and continued to sell them under license with their updated version of MacWorks Plus, re-branded as the Macintosh Professional.

Though no new Lisas were available for sale, development continued on MacWorks Plus to support the installed base of Lisas, making them as relevant as their closely related cousin, the Macintosh Plus.

Legacy

The Macintosh XL shares the same legacy as the Lisa before it. However, the increased sales from the emulation of the Macintosh operating system proved that the Macintosh family badly needed a more professional environment which could provide larger monitors, greater memory and more expandability than the Macintosh 512K
