The Macintosh XL was a modified version of the Apple Lisa personal computer made by Apple Computer. In the Macintosh XL configuration, the computer shipped with MacWorks XL, a Lisa program that allowed 64K Macintosh ROM emulation. An identical machine was sold as the Lisa 2/10 with the Lisa OS only.

The Macintosh XL had a 400K 3.5" floppy drive and an optional external 10 MB hard drive. At the time of release, the Macintosh XL was colloquially referred to as the "Hackintosh", although this moniker has also been used to more generally describe Macintosh computers assembled from unusual combinations of parts.

Because of its roots as a Lisa—and unlike all other Macintosh computers—the Macintosh XL did not use square pixels. The resolution of the Macintosh XL was 720x364. Square pixels were available via a physical screen upgrade that changed the resolution to 608x431.
