The MacBook Air, released in 2008, was the first Macintosh to not include a SuperDrive after it became standard across the line.
Unlike tray-style disc holders which have an inner guide ring, slot-style drives will not work with MiniCD or MiniDVD discs (8cm diameter instead of 12cm) unless an 8 cm optical disc adapter is used and extraction of the disc is difficult, requiring tweezers, use of a card with double-sided sticky tape, or complete disassembly of it. Apple never offered a Blu-Ray drive or supported playback of the format.
DVD-RAM support, notably, is absent though it can be unofficially enabled on some drive models. SuperDrives featured 6–24x write speeds and supported the DVD±R, DVD±R DL, DVD±RW, CD-R, and CD-RW formats along with all normal read-only media. The early 2001 release of the Power Mac G4 was the first Macintosh to include a SuperDrive. Once the use of floppy disks started declining, Apple reused the trademark to refer to the optical drives built into its Macintosh models, which could read and write both DVDs and CDs.

The SuperDrive is not supported in Mac OS X, not even on the few Old World ROM machines that can officially run OS X. The end of the SuperDrive coincides with the demise of Old World ROM Macs with the advent of the New World ROM machines, Apple stopped offering internal floppy drives on all models.

The PowerBook 1400 series also had a floppy drive module, but was incompatible with the other PowerBooks. The feature was dropped throughout the lineup during 1993–94. The drive as mounted on PowerBooks lacked the auto-inject feature of Apple's initial desktop SuperDrive implementation, requiring the user to manually insert the disk all the way into the drive. The PowerBook 190 series, PowerBook 5300 Series, PowerBook 3400c, and original PowerBook G3 shared the same interchangeable floppy drive module as a standard feature. Wallstreet) had an optional floppy drive module. The last model to include one was the beige Power Macintosh G3 series, which was manufactured until January 1999. Every Macintosh and PowerBook introduced from 1988–97 (with the exception of the PowerBook 100, PowerBook Duo series, and PowerBook 2400c, which offered a proprietary external floppy drive as an option), had a built-in SuperDrive floppy drive. The first Macintosh model to include a SuperDrive floppy drive was the Macintosh IIx (1988).

These two models can be upgraded via the M0244 upgrade kit (which replaces the IWM disk controller with the SWIM) and gain full use of the SuperDrive. The next two models to be released (Macintosh II & Macintosh SE (1987)) also shipped with that controller a SuperDrive connected to them will behave as an 800 KB drive. The SuperDrive cannot be used with the original four Mac models (Macintosh 128K through Macintosh Plus), as their disk controller (IWM) doesn't support high density. The controller card as well as the external Superdrive were discontinued in June 1994.
While the external drive worked on both Apple's product lines, it was mainly intended for use on the Apple II series, for which Apple introduced in 1991 a slot-based interface called the Apple II 3.5 Disk Controller Card for Apple IIe and II GS computers so they too could use 1.40 MB storage and read/write MS-DOS. Introduced in 1988 under the Trademark name FDHD (Floppy Disk High Density), the subsequently renamed SuperDrive was known primarily as an internally mounted floppy drive that was part of the Macintosh computer however, an external version of the drive was manufactured that came in a Snow White-styled plastic case. This was made possible as the SuperDrive now utilitized the same MFM (Modified Frequency Modulation) encoding scheme used by the IBM PC, yet still retained backward compatibility with Apple's variable-speed zoned CAV scheme and Group Coded Recording encoding format, so it could continue to read Macintosh MFS, HFS and Apple IIProDOS formats on 400/800 KB disks.

This drive was also capable of reading and writing MS-DOS formatted disks and FAT12 file formats, using PC Exchange or other software, unlike the 400 KB and 800 KB drives.
This replaced the older 800 KB floppy drive that had been standard in the Macintosh up to then, but remained compatible in that it could continue to read and write both 800 KB (double-sided) and 400 KB (single-sided) floppy disks, as well as the then-new high-density floppies. The term was first used by Apple Computer in 1988 to refer to their 1.44 MB 3.5 inch floppy drive. Internal SuperDrive floppy drive on a Macintosh LC II
