FCPX Bugs in the time line render files

You did NOT make a clean install. You have stuff that was installed in 2014!

You may have erased everything, but if you then migrated all your stuff, you would have in effect just reverted to the previous state.

Uninstall clamxav, for a start.

Then you have stuff that I would not recommend, like torrent stuff - this is a great vehicle for adware.

I would really do a clean install: erase, install and then migrate ONLY the user accounts.

We need information.

What version of macOS, FCP, what type of media?

Also, many issues could be due to third party software modifications, so please run Etrecheck and post its full report here, using the "additional text" button below your message.

The report says otherwise.

If you did a clean install after that report, please run Etrecheck again and post the new report.

We are not discussing a clean install because FCP is having an issue.

We are discussing a clean install because there are badly written, unuseful or damaging software that can make a system not work as intended; or simply stuff that is too old and does not work well in a newer OS.

It is a good idea to do a clean install at least yearly, at the time of a major OS upgrade. That leaves cruft behind and avoids conflicts between old extensions or daemons. Just about every claim about bugs in a new OS are due to the stuff installed before the upgrade.

The report can help with cleaning up orphan files.

Clean up:

~/Library/LaunchAgents/com.redgiantsoftware.updater.plist

/Applications/Red Giant Link.app

Executable not found

How can this be if there was a clean install? This is certainly not from a user account.

[Running] PowerMate (? - installed 2014-01-22)

Application

/Applications/PowerMate.app

Let me try to clarify: when you migrate the user accounts, then anything that goes into your own accounts' folders will be migrated. This includes the contents of your users' Library folders. So the contents of "user launch agents" will be restored, but not "launch agents" or "launch daemons", because those are in the overall Library folder.

For the record "user launch agents" are installed in ~/Library/LaunchAgents (the tilde means your home folder)

"launch agents" go into /Library/LaunchAgents (no tilde here; this is the main Library that affects every user)

"launch daemons" go into /Library/LaunchDaemons (again, they affect all users).

This does have the potential for creating "orphan" files: all it takes is for something in your ~/Library/LaunchAgents to try and launch an application or service that was not migrated back. Orphan files just do nothing, hence they typically appear under "clean up" in an Etrecheck report.

The extensions are still loading and running. Deleting the apps from the Applications folder doesn’t do much. You clearly did not do a clean install on the new operating system on the new computer.
