I hope the following suggestions are helpful to you in dealing with your slow computer. Often times there is a specific cause and other times any of the following actions may be helpful. They are “maintenance” steps which are often ignored.
· It is important to occasionally restart a Mac. Ideally, once a week or more often. This does some system cleaning.
· Regularly clearing the history of your browsers can help as all the data is stored in RAM. Clearing frees up RAM for system use. You have sufficient RAM installed but you still want to use it wisely.
· If your computer is set to startup with too many apps that will slow down the startup process.
· Some programs use a lot of RAM. (Like many Adobe apps and the Chrome browser.) When using them, close any other apps not being used.
· Doing a restart in the safe mode can clear a number of problems. This is done by holding down the Shift key at start up. This process can take up to ten minutes while the computer is doing its maintenance and cleans the cache. You may then restart normally.
· It is also a good idea to run the Disk Utility app. If it reports some issues, then rerun it repeatedly as needed until the final report is ok.
I hope these suggestions are helpful and enable you to speed up your computer.
