Randomly one day my mac started running very slow and thinking about every command for at least 5 minutes. I can not open any programs or applications on my computer. When I try to open anything, it thinks for a very long time and if anything does happen, it is an alert saying that the program has quit unexpextedly, without the program ever really opening. I can not do anything on itand it has vitrually turned into a very expensive paper weight. I don't know what to do, any suggestions???

    You have 2 possible avenues here.


    1) hardware

    2) software



    I always assume software here first for similar issues.


    I would start cleaning old caches, there are free software around that would clean all your /System/Libraries/Caches

    and your own home directory username/System/Library/Caches

    then all your temps etc.


    Then check to see if your harddrive is not too full. if it is, clean it up, or backup some stuff away.

    Then I would check the harddrive integrity with disk utility. Do a full disk check and check permissions too.


    If you open the activity monitor, do you see something chewing the processors (check the % column).

    if so, make sure you don't run that process.

    If all fails, reinstall macos.

    If it is still slow with a fresh macos installation, you may have a hardware problem.  (take it to a store).
