Hi, I purchased a refurbished Macbook Pro a week ago. It gets lag and freezes everytime I type too fast or open many tabs at once. What should I do? Thank you!!

Which applications exhibit this behavior?


Does this occur for a different user, e.g., Guest? How to test an issue in another user account on your Mac.


Does this occur after starting up in Safe Mode?


Consider the possibility of a third party software conflict.  EtreCheck can be used to investigate what is installed.

I agree with @fyip. Unless you purchased the refurb directly from Apple, then you should definitely backup the computer and erase the physical drive and reinstall macOS if you haven't done so since you acquired the laptop. You never know what the previous owner did to the software on the system. If you migrate your data from a backup, then do not migrate any apps or settings just to be safe since you don't want to migrate any settings from the previous owner.
