MACBOOK AIR (11-INCH, EARLY 2015), OS X El Capitan (10.11.2)
Hello there, Kali-ka.
It seems you are having issues with your mac not running smoothly or slowly. The following Knowledge Base article provides some great initial steps for troubleshooting:
OS X El Capitan: If your Mac runs slowly
If you find your Mac is running slowly, there are a number of potential causes that you can check.
An app you’re using may require more memory than your computer has easily available. To see how much memory your computer has, choose Apple menu > About This Mac, then check the amount of memory listed in the Overview panel. See the help that came with the app to find out its system requirements.
To find out how to increase your computer’s memory, choose Apple menu > About This Mac, click Memory, then click Memory Upgrade Instructions in the lower-right corner. (Not available on all computers.)
documentation that came with the app to its system requirements.
- To see what processor your computer has, choose Apple menu > About This Mac, then click Overview.
- To see what graphics card your computer has, choose Apple menu > About This Mac, then click Displays. The name of the graphics card in your computer is displayed in the middle of the window.
Your computer’s startup disk may not have enough free disk space. To make disk space available, move files to another disk, then delete files you no longer need on the startup disk.
Quit any apps you’re not using.
If you have problems with your disk, use Disk Utility to verify and try and fix any issues.
Use Activity Monitor to see if a particular app or activity is making a large demand on your Mac.
There are some additional pointers and recommendations in this article as well:
Start by asking yourself basic questions about the issue that will help you describe it:
What is the issue?
When answering this question, be sure to note any alert or "error" messages that appear. Be sure to describe any unexpected hardware or software behavior, and any other details that seem relevant.
Users accustomed to reading logs should review them in Apple System Profiler for any relevant information. If you are not experienced with reading logs, it is generally best to ignore them unless instructed to search for a specific message.
When does it occur?
- If you can identify a sequence of events that lead up to the issue, be sure to document each.
- If the issue seems to occur at certain time intervals, be sure to record the times at which it happens. Does it happen only at certain times (for example, daily at 9:00) or on a periodic basis (for example, every 47 minutes)?
- If the issue occurs so irregularly that you cannot yet describe when it happens, the suggestions below will help you troubleshoot the issue over time by making certain changes, then watching to see if the issue stops.
- If the issue occurs at startup immediately following a third-party software installation, find out what you can do.
- You can also troubleshoot any other issues that occur during startup.
If these suggestions do not resolve your issue, contact AppleCare or your nearest Apple Authorized Service Provider for assistance.
When did the issue start?
Note any recent changes to the computer and its software, since they could affect the issue. Was any new software or hardware installed?
Check documentation
After you can describe the issue, check known documentation sources, searching on key terms you have identified.
If an application program is affected, first check any "read me" files included with it. These may describe known issues.
If the issue is with a third-party product, check the manufacturer's or publisher's website for information about the issue.
Up-to-date software and firmware?
As a general rule, make sure you are using the latest versions of Apple and third-party software for best compatibility. Also make sure your computer's firmware is up-to-date.
Is it a software or hardware issue?
Pay attention to important clues.
- If the issue seems specific to a certain application or Mac OS X feature, troubleshoot software before hardware.
- If the issue occurs as the computer starts up--unless the computer does not turn on at all-- troubleshoot software before hardware.
- For other issues, or when software troubleshooting does not produce a resolution, use the rest of this document.
Thanks for reaching out to Apple Support Communities.
