My iMac has started hesitating when opening programs right away like it did before. Advice?
Computer processes can slow down over time
Over time, computers can start to drag or hesitate during start up, this most often means that there are excessive programs or processes running automatically when you power up the computer. Luckily, it is relatively simple to check out your iMac's start up routine and eliminate any non-essential programs that are slowing you down. By reducing the number of tasks the computer has to perform during its boot up process, you can directly increase its start up speed.
How to delete unneeded programs from your start up process
To review your iMac's start up menu and delete unnecessary processes, follow these steps:
1. Click the apple icon on the top left corner of your screen
2. Scroll down to choose System Preferences
3. This will open your computer system's configuration tools - under the System sub-heading, choose Accounts.
4. Click to highlight your account on the left side of the menu, then click to select the Login Items heading on the right side.
5. Everything that appears in this list is set to launch automatically when you turn on your computer. You can use the up and down arrows or click to select items to remove. To delete an application, first click to select it, then press the delete key on your keyboard.
6. ***Note: the option to "hide" an application is different than removing it from the list. if you choose to hide a program, it will still open at start up, but the process will be hidden from the user.
7. It's a good idea to remove everything that isn't needed, especially if you are interested in improving your computer's start up speed. However, keeping some programs set to automatically launch is a convenient way to pre-program the applications you use all the time.
Clear up some hard drive space
Another software-related tip is to clean up some space on your hard drive. The more space there is, the more flexibility and speed your system can optimize while running processes. You can do this pretty easily by emptying the trash, deleting unused programs, downloads and files, and by archiving old and infrequently accessed data into smaller files. The steps for this can vary among operating systems, so the most effective method is to visit the AppleCare Support pages and check out the advice offered there for your particular operating system model.
Enhance your hardware
In addition to software tweaks, there are also hardware options to increase your computer's speed. For example, adding RAM or upgrading your CPU can really boost your system's performance.
