Had a patron who accidently manually removed Cisco VPN from Apple computer, but when they tried doing re-install, said program was installed.
Need to remove the package manually using Terminal:
pkgutil --pkgsYou'll locate the package in the list of all packages installed....
com.cisco.pkg.anyconnect.vpnThen it's just a simple matter to tell the package DB to forget it with....
sudo pkgutil --forget com.cisco.pkg.anyconnect.vpnThe majority of the students in my law school have Apple laptops, and I try to help them fix the basic issues:
No matter how much internal storage your Mac came with, you always want to keep at least 10 percent of it empty to make sure your Mac runs smoothly.
Open the Apple menu and select About This Mac > Storage to find out how much storage you're currently using. This shows you a breakdown of the file types taking up your storage, including System, Documents, Photos, and more.
If you don't have much free space, click Manage to see what you can do about it.
Also, check out our guide on creating free space on your Mac for the best space-saving tips. We'll show you how to uninstall old apps, find and delete large files, and move your documents to the cloud.
Activity Monitor is built into macOS and shows you which apps and processes are using your computing power. If your Mac feels like it needs a tune-up, you can use Activity Monitor to find out which apps are slowing it down.
Launch Activity Monitor from the Utilities folder in your Applications, or by searching for it with Spotlight (Cmd + Space).
Then use the CPU tab to find apps or processes using a large percentage of your CPU. You can also use the Memory tab to see which apps and processes are using your RAM.
If you find an app or process using more power than it should, highlight it and click the Stop Sign icon to close it down. Make sure you only close processes you're familiar with to avoid damaging macOS.
Is your Mac slow to boot up? You might have too many applications opening at startup. Go to System Preferences > Users & Groups and select your user account. Then click the Login Items tab to see a list of everything that launches whenever you log in.
Highlight the apps you don't always want to open and click the Minus (-) button to remove them. This doesn't delete the app from your Mac; it only stops it launching automatically when you log in.
4. Run a Scan for Malware
Your Mac is less likely to become infected with malware than a Windows PC, but it's not impossible. In fact, if you don't follow best practices it can still be easy to infect your Mac with malware by mistake.
Download and install Malwarebytes---the best antivirus software for Mac---to run a scan on your Mac. You don't need to keep this app open all the time; just run a scan using the free version every now and then to give your Mac a quick tune-up.

Over time, your Mac builds up caches of files from various applications and websites that it uses to load content faster. Unfortunately, these caches sometimes get so large---20GB or more in some cases---that they become more of a hindrance than a help.
You can safely empty the caches from the Library folder in Finder. After you do so, some apps may appear slower as your Mac builds the caches up again, but before long your Mac will run better than before.
To clear the caches:
