Spinning beachball stalling login and slowing down my iMac

I have an Retina 5K iMac 2017 running macOS Ventura 13.7.8

When the iMac boots up I will get an initial spinning ball once I select a login user I will get another spinning ball for several minutes before I can enter in the login password. Then after the login password. I will get another spinning ball before the system finally comes up. Some of these spinning balls take 15-20 minutes before progressing to the next login step, with the last one taking about 30 minutes. After doing some research in this community I downloaded EtreCheck Pro (power user package) so I am including the report in the hopes that someone can offer a solution.

Thanks.

Yes, it is called "BrickMyMac" around here, just due to the amount of times we have seen those problem. There is a simple rule to keeping your Mac running optimally and that is never install any:

  • Cleaners
  • AntiVirus
  • VPN - Unless you a a specific reason to "tunnel" into a work servers, and even then you would be given the settings and VPN to use for their purpose. They do not offer you any security and the opposite is true that your security and privacy are more at risk.


The problematic files that have been installed are:

  • PC Matic
  • iBoostUp
  • CleanMyMac 2
  • CleanMyMac 3
  • CleanMyMacX
  • ProteMac
  • TunnelBear
  • All Unsigned files as noted in the report.


Your drive performance is also suffering due to the weight of all this activity and your write speed should be showing well over 1000 MB/s instead of the 703 MB/s. The SIMBL Scripting addition has crashed 408 times and launches on every startup showing it was installed in 2011.


It is due to all the bloat and the difficulty and time it would require to uninstall these files that erasing and starting over would be recommended. If you do have a backup, that may be useful for your data files, but you would not want to restore Applications that would put you in the same state with their files appearing in your System Launch folders.


I would be willing to assist without doing the Clean Install, but you would need to realize that it may still be a futile effort and just a waste of time. The System Extensions can be very difficult to remove, if even possible, due to them now being baked into the OS from a previous install many years ago when the file system was not locked. Having a backup would still be necessary as you may find that an unintended file is removed and the OS will be trashed. It may help get you back to a usable computer, but not nearly as efficient as a clean install.

Deleting it does not undo the damage it is capable of inflicting. Neither does reinstalling macOS. I know from experience. It can be done, but it's not worth the effort. It can take a day just to determine what's wrong.


By all means try everything short of that though, and creating a TM backup is an absolute must before doing anything else.


I didn't get into the other troublemakers Mac Jim ID enumerated, which can be removed. "Cleaning" apps on the other hand are destructive. Once installed and used, the damage is done, and there is no "undo" short of restoring a TM backup created prior to using it.
