After a few years, a Macintosh-native development system was developed.

Later, the same Lisa Workshop was used to develop software for the Macintosh.

During this development process, engineers would alternate between the two OSes at startup, writing and compiling code on one OS and testing it on the other. Indeed, a separate development OS, called Lisa Workshop, was required.
Third-party software: A significant impediment to third-party software on the Apple Lisa was the fact that, when first launched, the Lisa Office System could not be used to write programs for itself. The final revision of the Lisa, the 2/10, was sold as the Macintosh XL. The cheaper and better version of Lisa personal computer was released it in January 1984. More than 100,000 Apple Lisa computers were fabricated and sold in two years, from 1983 to 1885, as the high price, relatively low performance and unreliable Twiggy floppy disks led to poor sales. Besides the packs often busts open and leaks corrosive acid that ruins the circuit boards. Lisa’s real-time clock depended on a 4 x AA-cell NiCd pack of batteries that only lasted for a few hours when mains power were not present. 
In fact one of the Lisa’s most important roles in Apple history was that this computer served as a programming platform for the early Macs. In January 1985, the Lisa 2/10 was renamed the Macintosh XL, and outfitted with MacWorks, an emulator that allowed the Lisa to run the Mac OS. The Lisa 2 cost half as much as the original, replaced the two 5.25″ drives with a single 400 kB 3.5″ drive, and offered configurations with up to 2 MB of RAM, and a 10 MB hard drive. Realizing this, Apple released the Lisa 2 at the same time as the Mac. When the Macintosh came out in 1984 for significantly less money, it eroded the Lisa’s credibility further. At $9,995 it was a plunge few businesses were willing to take. The Lisa had a Motorola 68000 Processor running at 5 MHz, 1 MB of RAM two 5.25″ 871 kB floppy drives, an external 5 MB hard drive, and a built in 12″ 720 x 360 monochrome monitor. Apple promoted the Lisa computer announcing that the machine would increase productivity by making computers easier to work with. Said to be named for one of its designer’s daughters (see paragraph above), the Lisa was the first personal computer to use a Graphical User Interface and it was aimed mainly at large businesses. Decades later, Jobs would tell his biographer Walter Isaacson: “Obviously it was named for my daughter.” (source: Wikipedia about Lisa computer). Privately, Hertzfeld and the other software developers used “Lisa: Invented Stupid Acronym”, a recursive backronym, while computer industry pundits coined the term “Let’s Invent Some Acronym” to fit the Lisa’s name. Andy Hertzfeld states the acronym was reverse engineered from the name “Lisa” in late 1982 by the Apple marketing team, after they had hired a marketing consultancy firm to come up with names to replace “Lisa” and “Macintosh” (at the time considered by Jef Raskin to be merely internal project codenames) and then rejected all of the suggestions. Since Steve Jobs’s first daughter (born in 1978) was named Lisa Nicole Brennan, it was usually inferred that the name also had a personal association, and perhaps that the acronym was a backronym invented later to fit the name. While the documentation shipped with the original Lisa only ever referred to it as The Lisa, officially, Apple stated the name was an acronym for Local Integrated System Architecture or “LISA”. #Mac lisa emulator upgrade#
Screen resolution after this upgrade was 608 x 431.

An optional screen upgrade was available which allowed the Mac XL to use square pixels, for better Mac OS emulation. The Lisa 2 and MacXL used 2 400 kB Sony 3.5″ floppy drives, and both had 10 MB hard drives.
The Lisa included a single parallel port, which was dropped later in the Lisa 2 and MacXL. Price: Original price $9,995 (monitor not included). Display: 12” monochrome monitor sold separately. Possible Expansion:Three internal slots available. #Mac lisa emulator serial#
Ports: One parallel and two serial ports, mouse port. OS: Apple Lisa GUI (Graphical User Interface). With the introduction of the Lisa 2/10, an optional 10 MB internal proprietary hard disk manufactured by Apple, known as the “Widget”, was offered. 
Storage:Two 5 ¼ inch Apple FileWare 5.25-inch double-sided floppy disk drives, known as Twiggy.
