Many programs that you don’t need running at startup can slow your system down or make it take a long time to boot. You can use a command-line program with the cheerful name MSConfig to see what’s being loaded, but if you want a more visual, easy-to-understand way to turn off startup items, there’s an app for that: Task Manager’s Startup tab.
Startup items are programs that load during the boot sequence, before the user logs in and can be run by the operating system to provide services, such as virus protection or a firewall. They can also be programs that are started by the user and are launched from a user folder or shortcut.남자소자본창업
Most startup items are shell scripts that can execute a wide range of commands. They must be designed carefully to avoid taking too long to complete their tasks, as any delay in loading the operating system can cause problems. To minimize system startup time, a startup item should only perform a few short tasks and exit. If a startup item must perform lengthy tasks, it should spawn off a background process to perform these tasks. This allows the background process to perform the tasks as fast as possible, without delaying the system startup.
The operating system uses the Requires and Uses parameters of the /Library/StartupItems directory to track the dependencies of its startup items. This is used to prevent startup items from starting up daemons that already have been started by other startup items. However, since OS X v10.4 the majority of low-level services are started by the launchd daemon, so the Requires and Uses arguments are largely irrelevant for these types of startup items.
In addition to the /Library/StartupItems directories, some startup items create their own folder in the user profile directory to store their autoloading scripts and settings. These are typically called the Startup Folder, and you can find them in Finder by using the Go menu or typing /Library/StartupItems into the search box.사업아이템
A lot of Mac apps are set to launch at login, whether they’re checking for malware or syncing data, and this can increase your computer’s processor and memory capacities and slow down its performance. Fortunately, you can disable unwanted login items and get your Mac to load faster at startup with the help of an app like CleanMyMac X.
Note: Editing the registry can cause serious issues with your system and may require a reinstall of Windows. Before attempting any changes, back up your registry by pressing Win-r and entering regedit. If you are unsure about what to do, consult a computing support professional.
