my imac is getting really slow and locking up
My iMac running latest software runs really slow and is constantly locking up. Particularly Google Chrome and Apple News. I keep programs up to date and don’t have high CPU usage programs running. It get to the point where my only option is to do a hard shut down with the power button. Even then a reboot takes 5-10 minutes. Is this thing cooked or is there a way to “defrag” like a PC. I have plenty of storage and really only use this device for internet and basic household use/storage. I also have an external hard drive attached that we use for photos and backups
