Mac pointer won't let go — iMac

Well to be honest I haven't seen a system with this much wrong in awhile! Below is what the report indicates:

• This machine has multiple antivirus apps installed. Clearly you have or had multiple antivirus apps installed. I can see evidence of Kapersky AV which is really nasty stuff that can cause similar issues as you are experiencing. Not to mention it makes Mac OS appear slow, unstable and just buggy.
• TuxeraNTFSUnmountHelper This is a hack that allows you to share an external HD with a Windows machine. It is also dangerous and potentially damaging to Mac OS.
• CocktailSchedule This is ancient maintenance app that is today worthless. It should have been uninstalled years ago.
• silentcleanserver This is some type of cleaning app.
• Kaspersky Lab Clear evidence that left over pieces of the Kapersky AV app was installed.
• Torrent Torrents are most often used for downloading unpaid for apps. This is extremely dangerous as they also pass along malware not to mention if you are using it for that purpose, that is simply theft. There are some legitimate uses for a torrent, however they are pretty rare though.

Also, you apparently do not seem to care about your data as there is zero evidence you have ever backed up the computer. This is a 100% guarantee you will lose data. At the very least you should be using Time Machine to backup and safeguard your data.

My suggestion is that you do an erase and install and start over again. This will wipe out everything on the computer! Then while in the Recovery Partition you can install Mac OS and install your third party apps.

Good luck.

Please follow the advice in Organize files in folders on Mac - Apple Support

If you continue to have a problem, please restart the computer in Safe Mode and then restart normally and retest.

By the way, do you have any of the following third party apps installed:

1. Antivirus apps
2. Security apps
3. Cleaning apps
4. VPN apps
5. Maintenance apps

Don't copy things willy nilly onto an External Hard Disk, to backup please use Time Machine. If you are not familiar with Time Machine please click Back up your Mac with Time Machine for how to do so. It is incredibly easy and only requires an External Hard Disk. For an External Hard Disk I'd recommend a OWC Mercury Elite Pro due to their reasonable cost, high reliability and OWC service. They are a US company so if you are not in N.America they will ship, however shipping can be expensive. For that reason, they have dealers all over the world. If you need to find a list of overseas dealers let us know.
