Question about memory


rcently mac become slow. slow. gets little twirly rainbow scrolling webpage. or typing. in activity monitor says have have 450 mb free memory... normal? , can - except add on more?
 

os x utilise ram possible best performance. don't worry that. there's different issue.

try checking hdd smart data ensure it's not corrupted. other 'passed' means need new hdd. you can download smart utility here.

if smart utility comes clean, try verifying volume in disk utility. if there issues, you'll need repair through recovery partition (please quote if need assistance).

if disk utility comes ok (basically, no red writing), can try restarting mac option 'reopen windows when logging in' disabled. this prevent background memory leaks/software conflicts reopening.

if still doesn't make positive impact, , none of above troubleshooting steps have indicated issue, try:

- ensuring os up-to-date
- repair disk permissions in disk utility & restart
- reset nvram/smc

speak soon.
