Browsers can experience memory leaks , in which they allocate some of your Mac ’s volatile or participating memory board ( RAM ) and do n’t release it when they ’re finished . This can happen in Safari , Chrome , Firefox , and others – Chrome was once a notable memory leaker and has gotten better , but Safari often swells , too .

Find the culprit
The Activity Monitor app takes implicit in arrangement technological data and submit it in a much more friendly fashion . ( Find it inApplications > usefulness . ) In Activity Monitor , I depend primarily to the CPU , Memory , and Energy tab key to figure out when macOS or a single app is slow , or I ’m having peculiar problems with reactivity .
Click a pillar oral sex in each tab to separate by the worst wrongdoer . In CPU , click% CPUuntil the arrow next to it is pointing down . In Memory , tick theMemorycolumn . In Energy , click theEnergy Impactcolumn .
If your Mac is respond poorly , CPU and Memory can help . You might see the app you ’re using or another app using a tremendous part of current C.P.U. bodily function or a lot of store . The chart at the bottom of the window shows overall load compared to available computational power for CPU , and overall retentivity in use for Memory . If macOS needs more memory than it has in the form of RAM , it can swap not - in - use parts of apps and data to the SSD , resulting in eminent “ memory pressure , ” which is color - take in in that tab ’s chart .
Use the Force Quit Applications dialog to kill apps quickly.
The Energy tab can also be a useful tool in identifying an app consuming scads of resource and if you ’re wonder why your laptop ’s battery is drain so quickly .
One eventide my M1 MacBook Air was closely blister to the touch , even though it had been sleep . Checking Activity Monitor led me to a tiny app that had , for no reason , gone out of control . I quit it , and it has n’t tried to practice that much CPU power since .

Restart your Mac
It sometimes seems like Mac users feel that restart their computer is a moral failing , a blight on Apple , or a immense time waster . While I ca n’t absolve Apple of falling short of perfection , I would like to absolve you of shame and disabuse you of concern about clip .
As with Safari , macOS has come a long style in deal with both designed and forced restarts . Typically , most apps store data as you ’re seduce changes or you ’ve internalized the Command - S shortcut to save frequently .
When you select > Restart , you could opt to check over “ Reopen windows when logging back in , ” which automatically reopen all apps when the organization comes back up , almost always restoring you to their previous working state , either because of built - in defaults or because they consult the system - wide taste at > System Preferences > Desktop & Dock(disable “ Close windows when quitting an program ” ) .

That ’s a worthwhile investment if you ’re cursing at your screen or waiting second for actions to complete that should take place instantly .
I have lately run into the point a few clock time with Sonoma ( though not with the very latest update , fortunately ) where something went deeply off - track in macOS . Not only did apps not fully quit when kick the bucket ( normally or via Force Quit ) , but the menu - based restart failed . call up that , in those circumstances , you ’ve got two fallback design if you ca n’t re-start unremarkably . admonition : Both options instantly re-start your Mac , so you may lose unredeemed datum if all your apps have spare their file or ones with unsaved data are unresponsive .
