The Macintosh LC 500 series is a series of personal computers that were a part of Apple Computer's Macintosh LC family of Macintosh computers, designed as a successor to the compact Macintosh family of computers for the mid-1990s mainstream education-market. The all-in-one desktop case is similar to the then recently introduced Macintosh Color Classic, but the LC 500 series is considerably bulkier and heavier due to its much larger screen and a bulging midsection to house the larger electronics, including a 14" CRT display, CD-ROM drive, and stereo speakers.
The LC 500 series included four main models, the 520, 550, 575, and 580, with the 520 and 550 both using different speeds of the Motorola 68030, and the 575 and 580 sharing the 33 MHz Motorola 68LC040 processor but differing on the rest of the hardware. All of these computers were also sold to the consumer market through department stores under the Macintosh Performa brand, with similar model numbers. The LC models, in particular, became very popular in schools for their small footprint, lack of cable clutter, and durability. The Macintosh TV, while not branded as an LC, uses the LC 520's case (in black instead of beige) and a logic board similar to the LC 550. The compact Color Classic series shares many components, and is able to swap logic boards with the early 500 series machines.

The Macintosh LC 520 was introduced in June 1993. The case design was larger than the compact Macintosh models that precede it, due in large part to the significantly larger screen and CD-ROM drive.
The LC 520 got its start as a design project codenamed "Mongo". Following the success of the Color Classic, The Apple Industrial Design Group (IDg) began exploring the adaptation of the Color Classic's design language, dubbed Espresso, for a larger display version that would also include a CD-ROM drive. However, IDg hated the design so much that they permanently shelved the final concept. In 1992, Apple CEO John Sculley demanded a large-screen all-in-one design to fill out his market strategy in less than 6 months. Over IDg's objections, Apple's engineering team retrieved the shelved design and promptly put it into production. Because IDg universally detested the design, they immediately began the redesign project that would become the Power Macintosh 5200 LC series less than two years later.Kunkel, Paul. AppleDesign: The work of the Apple Industrial Design Group, with photographs by Rick English. New York: Graphis, 1997, p.243
The LC 520 has been described as if you "take an LC III and graft on a 14{{pprime}} Trinitron monitor along with stereo speakers". The logic board of the 520 is broadly the same as the Macintosh LC III, with a Motorola 68030 CPU and an optional Motorola 68882 FPU.{{cite web | url=https://lowendmac.com/1993/mac-lc-520-performa-520/ | title=Mac LC 520 (Performa 520) {{pipe}} Low End Mac | access-date=September 12, 2022 | archive-date=September 12, 2022 | archive-url=https://web.archive.org/web/20220912024621/https://lowendmac.com/1993/mac-lc-520-performa-520/ | url-status=live }}
Peter Lewis of New York Times praised the LC 520, writing that its $1,599 price point is "perhaps the best value in the entire Macintosh product line ... it would be very difficult to put together a Windows-based PC with the same features for that price, and Windows computers are usually much less expensive than Macs". He regretted the computer's unavailability in the United States outside schools. Lewis also noted that the unit's 40-pound weight would make it difficult to carry home at night.{{cite news

}} While Apple did not rule out offering it to non-educational customers, MacWEEK wrote that the timing of the LC 520's release coincided with purchasing timelines for schools, and that the decision to market the computer exclusively to the education market was part of a strategic shift to move the LC brand away from retail.
The LC 520 was discontinued in February 1994, when it was replaced by both the faster but otherwise essentially unchanged Macintosh LC 550 and the new, 68LC040-equipped Macintosh LC 575. Apple sold upgrade kits for the LC 520 that brought it to the same specifications as the LC 550 or 575.

The Macintosh LC 550 replaced the LC 520 in February 1994. The Performa variants were introduced earlier, the 550 in October 1993 and the 560 in January 1994, and remained available for more than a year longer, until April 1996.
The main difference between the 550 and the 520 is the faster 68030 CPU, clocked at 33 MHz instead of 25 MHz, with the bus speed also increasing from 25 to 33 MHz. Unlike the 520, the optical drive was a bare-CD tray-loading type which did not require a caddy. The logic board in the 550 is essentially the same one used in the Macintosh Color Classic II, an upgrade to the original Color Classic not available in the United States. Apple also offered the same upgrade package for the 520 to the LC 575 logic board.{{cite web |url=http://docs.info.apple.com/article.html?artnum=17055 |title=Macintosh Family: Upgrade History |archive-url=https://web.archive.org/web/20020905064353/http://docs.info.apple.com/article.html?artnum=17055 |archive-date=September 5, 2002 |work=Apple }}
Two Performa variants were introduced, varying only in the software bundle that was included. The 550 included only consumer applications. The Performa 560 was called the "Money Edition" owing to a partnership between Apple and Money magazine.{{cite web

The Macintosh LC 575 was available from 1994 to 1996. It retains the "all-in-one" case of the LC 520/550, but uses the LC 475's architecture with a Motorola 68LC040 CPU (at a speed of 33 MHz instead of 25 MHz) and a tray-loading optical drive. It also included a high density floppy disk drive. The CPU clock is sometimes given as 66 MHz, since the clock signal is of that frequency - however, the processor itself only runs at 33 MHz. The LC 575 also introduced the comm slot, which was included in most later LC models as well.
In May 1994, a set of Performa variants were introduced: the Performa 575, 577 and 578.{{cite magazine

The LC variant was succeeded by the Macintosh LC 580 on the lower end or the PowerPC-based Power Macintosh 5200 LC models at the higher end. The Performa variants were sold until the 580 was discontinued.
This model is a favorite motherboard donor for those wishing to upgrade the Color Classic to a faster class of processor. Apple also offered an upgrade path in the form of a PowerPC Macintosh Processor Upgrade.

The Macintosh LC 580 was sold from April 1995 to May 1996. Like the LC 575, it is built around a Motorola 68LC040 processor, running at 33 MHz. However, instead of using the same sized, SCSI-only, logic boards based on the LC 475/Quadra 605 like the LC 575, the 580 uses the larger logic board of the Performa 630. This meant a few changes, most of them leading to lower prices, but also lower performance: Most notably, the hard drives of the 580 were IDE drives instead of SCSI drives. Also, the video RAM was no longer mounted on a SIMM, but used 1 MB of the 4 MB of main RAM soldered to the motherboard. Lastly, the Trinitron display of the 575 was replaced with a cheaper shadow mask screen, causing a slight change in the plastic case surrounding the CRT. One benefit of this change was the ability to accommodate the same video capture and TV tuner cards designed for the Performa 630. This allowed LC 580 users to watch and record video, essentially performing the function of a television as well as a computer.

Apple also offered an upgrade path for the 580 in the form of a PowerPC Macintosh Processor Upgrade. The 580 can also be upgraded with the following logic boards: 5200 LC, 6200, 5260, 5300, 6300, 5400, 6400, 5500 and 6500.
