Is it Problematic?

AppleSpell checks spellings for all kinds of applications including third-party software.  Although there are a few exceptions, one of which is Microsoft Office Suite. You are not required to manually start the AppleSpell as it starts along with your OS boots up. This application will be always running in the background and there is nothing to be alarmed of. It is a very light program and It generally does not consume much of the computing resources, although some users have reported that AppleSpell has been eating a lot of processing power and memory, because of which their system is slowing down. We will now go through a few troubleshooting methods to fix such problems.

Some fixes for AppleSpell High CPU and RAM consumption.

  1. Disabling your Autocorrect and Spelling correction feature. You have the choice for disabling this feature for all of the programs or you can disable it for specific programs. Go to your Keyboard settings by:
    opening the System Preferences >Keyboard>Text> 
    And uncheck Correct Spellings Automatically.
