iMac slow to wake

This is minor but make help overall performance. When I look at:

• Launch Agents
• Launch Daemons
• User Launch Agents
• Internet Plug-ins
• and 3rd Party Preference Panes,

I see a number of items that are much older than your iMac going back to 2007, likely the result of using Migration Assistant (and one reason I don't use MA). As the macOS gets newer, there is increasing evidence that very old apps and processes can slow the system.

One known to do this is DivX, which you have, and yours is date-stamped 2007!

Good rule of thumb: If you use it, keep it updated. If you don't, dump it.

Some third-party apps may not have been updated in a while but it is still worth checking.

Uninstall both Sophos & Trusteer antivirus apps. It’s a miracle your Mac runs at all with that installed. Mac OS does not benefit from not does it require ANY third party antivirus apps. If simply kept up to date and otherwise left alone Mac OS is extremely secure!!! Locate the the developers uninstall instructions for Sophos and Trusteer and Mac OS should become stable.

Third party av apps have the exact opposite effect a user desires, the make make Mac OS slow and unstable and add ZERO benefits.

Yes, download the app Find Any File and do a search for the word Trusteer and delete all files. When you deleted Sophos did you use the developers instructions??

Good work. :)
