In Mac OS X 10.2, the internal codename "Jaguar" was used as a public name, and, for subsequent Mac OS X releases, big cat names were used as public names through until OS X 10.8 "Mountain Lion", and wine names were used as internal codenames through until OS X 10.10 "Syrah".
This caused numerous short circuits, which required hours of costly diagnosis and hand rework to fix. Apple designed a new circuit board with more layers and normal-width traces. The new logic board was laid out by one designer on a huge drafting board, rather than using the costly CAD-CAM system used for the previous board, and the new design ...
Battery: A 3.6 V 1/2AA lithium battery, which must be present in order for basic settings to persist between power cycles, is located on the logic board. Macintosh SE machines which have sat for a long time have experienced battery corrosion and leakage, resulting in a damaged case and logic board. Some SE models feature a board-mounted battery ...

The iMac is a series of all-in-one computers from Apple Inc., sold as part of the company's Mac family of computers. First introduced in 1998, it has remained a primary part of Apple's consumer desktop offerings since and evolved through seven distinct forms.
Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.
[3] [4] On the other hand, a failure to do so will result in a different outcome where a different sound will be heard in place of the startup chime. This would either be the Chimes of Death (for most Old World ROM Macs made from 1987 to 1998) [ 5 ] or a series of simple beep codes (for Macs made from 1998 onwards). [ 6 ]
An analog board is a circuit board that contains the majority of analog circuitry in certain Apple Macintosh computers. The analog board was one of two circuit boards within many early Macintosh computers, including the Macintosh 128K/512K/Plus, Macintosh SE series, and Macintosh Classic series. The analog board contained several capacitors, a ...
