Giới Thiệu · CPU Speed Menu
CPU Speed Menu allows you to switch between the different performance settings
of your computer by a single mouse click. It is no longer necessary to open
System Preferences, navigating to the Energy Saver pane and selecting the
Options item. This is helpful for users who must switch between different
speed settings very often, for example when temporarily performing processor-intensive
tasks. Switching manually to a speed which meets your current needs best
can improve battery load on portable computers, or avoid noise problems with
cooling fans and power supply units on desktop computers.
CPU Speed Menu can be used on all Macintosh computers which support manual switching of processor performance. This includes all portable computers with PPC processors, as well as most G5 systems.
