When you turn on your computer, a lot of apps start running without asking your permission. These programs are called startup items or login items, and they can take up valuable resources, increase your boot time and slow your system down. The good news is that it’s easy to reduce the number of startup items on your Mac. You can do it with the built-in OS X utilities or with third-party software. Getting rid of unneeded apps and services can make your computer faster, run more reliably and use less power.
The majority of startup programs are applications that start automatically. Some are visible as icons in the system tray, such as antivirus or iPod syncing utilities. Others are invisible, running in the background and checking for new software updates. Both types can take up memory and CPU, making your computer more likely to overheat or run slower than it should. In addition, they can add to the startup time of your system and increase its energy consumption.
Many of these apps have on/off switches in their menus, usually under Settings or Preferences, Options or Tools. This is convenient if you are sure you want to disable the app at startup, but it’s not an effective way to get rid of all of them.
If you want to disable an app, you have to remove it from the /System/Library/StartupItems folder and the corresponding /Library/StartupItems/ subdirectories. In some cases, these files are essential for the proper functioning of your machine, so be careful when deleting them. If you are not completely sure that an item is no longer needed, double-check in the Apple Support forums or a search engine before sending it to Trash.
Alternatively, you can use a command-line program to check and disable the hidden startup items on your computer. This program, which was available for Windows prior to Windows 8, is known by the cheery name of MSConfig. 후토마끼창업 However, since Windows 8, you can now find a much more user-friendly and visually appealing way to manage the startup process by using the Task Manager’s Startup tab.
The Startup tab of the Task Manager displays all the programs that will run as soon as you log in, including their status (enabled or disabled) and the startup impact they’ll have on your system. The Startup impact is calculated in terms of how long it will take for your computer to fully boot and how much system memory they’ll consume.창업아이템
Aside from the Startup tab, the Task Manager offers other ways to optimize your computer’s startup sequence. For example, you can delete unnecessary system files from the HKLM registry hive to speed up the machine’s boot times. You can also edit the startup entries within the /etc/boot.d file to modify the order in which these items will load at boot. This file is not recommended for inexperienced users and is best left alone unless you need to make significant changes to the booting sequence.
