"About This Computer" Mac OS 9.1 window showing the memory consumption of each open application and the system software itself. Historically, the classic Mac OS used a form of memory management that has fallen out of favor in modern systems. Criticism of this approach was one of the key areas addressed by the change to Mac OS X.
It is the earliest Macintosh model that can be used as an AppleShare server and, with a bridge Mac, communicate with modern devices. [3] The Mac 512K originally shipped with Macintosh System 1.1 but was able to run all versions of Mac OS up to System 4.1. It was replaced by the Macintosh 512Ke and the Macintosh Plus. All support for the Mac ...
Because much of the Toolbox is implemented in ROM, alongside the computer's firmware, it was convenient to use as a bootloader environment. In conjunction with resources stored on the ROM chip, the Toolbox can turn the screen gray, show a dialog box with the signature "Welcome to Macintosh" greeting, and display the mouse cursor.
A hidden Hierarchical File System (HFS) disk volume contained in the read-only memory (ROM) includes System 6.0.3. [20] The Mac Classic can be booted into System 6.0.3 by holding down the ⌘ Command+⌥ Option+X+O keys during boot. [20] Some dealers included a software bundle called Smartbundle with the Classic. [21]
A system extension called MODE32 enables access to installed extra memory under System 6.0.8. Under System 7.0 up to System 7.5.5 the SE/30 can use up to 128 MB of RAM. Alternatively, replacing the ROM SIMM with one from a Mac IIsi or Mac IIfx makes the SE/30 "32-bit clean" and thereby enables use of up to 128 MB RAM and System 7.5 through OS 7 ...
Target Disk Mode (sometimes referred to as TDM or Target Mode) is a boot mode unique to Macintosh computers. When a Mac that supports Target Disk Mode [1] is started with the 'T' key held down, its operating system does not boot. Instead, the Mac's firmware enables its drives to behave as a SCSI, FireWire, Thunderbolt, or USB-C external mass ...
A sparse image is a type of disk image file used on macOS that grows in size as the user adds data to the image, taking up only as much disk space as stored in it. Encrypted sparse image files are used to secure a user's home directory by the FileVault feature in Mac OS X Snow Leopard and earlier. Sparse images can be created using Disk Utility.
Disk Copy was used for creating and mounting disk image files whereas Disk Utility was used for formatting, partitioning, verifying, and repairing file structures. The ability to "zero" all data (multi-pass formatting) on a disk was not added until Mac OS X 10.2.3 . [ 5 ]
