Issues uploading to Vimeo (Your system has run out of application memory??)

Preference Pane: ~/Library/PreferencePanes/MouseLocator.prefPane

Preference Pane: ~/Library/PreferencePanes/Perian.prefPane

Perian has not worked in years, and should not be used.

Open System Preferences, control-click on Perian and choose Delete.

And you have those NASTY things.

Chrome and its keystone things are sworn enemies of video applications, and of general performance in your mac.

Cleanmymac... let's just say that the catchphrase for it is "cleanmymac claims another victim".

Completely uninstall Cleanmymac, following their instructions. It is NOT enough to drag the application to the trash.

See https://chromeisbad.com for an explanation of what the keystone thingies do, and how to completely uninstall.

Then restart your mac, and post a new Etrecheck report.

There are many things installed, probably some of them have been there for years - how else would Perian be there?

There's probably something else involved not just the open applications specifically. That said, is there any reason to keep any of the applications open while running the process. I understand it probably hinders your productivity, but perhaps no more than having to run the uploads multiple times.

I believe Vimeo has a watch folder app in the App Store that will upload file to their servers. So if it can afford to shut down the other applications it would be helpful.

The ErtreCheck Report might well point to some other issue that's a more primary cause of the problem than the applications themselves.

I totally concur with Ian and Luis. Following are instructions which I believe Luis posted a while back on doing a clean install.

1) Make a full backup, preferably two: a Time Machine, and a full bootable clone, on a separate drive. You can use the free version of SuperDuper! to make this clone, or perhaps Carbon Copy Cloner.

NOTE: it is important to have more than one backup, since you're about to erase the main drive

2) Erase and install. I advise you to create an installer on a usb stick, to avoid having to install over the internet (slow).

Instructions here: How to create a bootable installer for macOS - Apple Support  How to create a bootable installer for macOS - Apple Support

NOTE: to erase, start from the usb installer disk, choose Disk Utility and erase the whole internal drive (not just the volumes inside); choose APFS with GUID Partition Map.

4) Quit Disk Utility and start the installation on the now empty drive

5) When asked if you want to transfer information, choose "From another mac, disk or Time Machine backup", and select the backup you made in step 1.

IMPORTANT: Migrate **ONLY** the user accounts (NOT applications, NOT settings, or other files)

6) Install any applications you really need, from the App Store or the respective developers' sites.

Even though this is a rather large upload, I don't see why it would do this under normal circumstances. This is why I asked for an Etrecheck report, so we can see if there is something that might be causing this behind the scenes.

Is it 4K or 1080p?

Even Apple's standard 20,000kbps for 1080p is OTT and unless your movie is high octane action stuff, 10,000kbps should give more than enough quality.

What bitrate was the original footage shot at? There's no point in exporting at more than the original.

If your problem is caused by an accumulation of crud, updating, upgrading or reinstalling the OS will only add further problems to it.

The only solution is a complete erasure of your hard drive and a clean install of the OS. Your computer will then be in the same condition as the day it left the factory.

It's not as big a deal as you may imagine and will probably be quicker in the long run than all the procrastination you are undergoing at present. In fact you could have done it several times over in the time you have been discussing your problems.

The basic reinstallation should only take an hour or so and you don't need to reinstall every app. Just install the ones you require and do the others as and when the need arises.

Needless to say, backup everything of importance before you start erasing the drive.

Crash reports can be understood by engineers, not the normal users here.

Nothing jumps out at me in the Ettrecheck report other than the SoftRAID driver being very old and a slow 480Mb/s USB drive that's connected.

I wouldn't be surprised if CMM did some deep damage that only a wipe and reinstall will cure.

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

All of what Luis said, plus I think it’s time to rebuild your system, clean wipe and reinstall of the system migrating only the users. Reinstall the apps. You’re carrying a lot of stuff that’s loading in the system and not doing, can’t do, anything at all. Disk Warrior is so dead plus everything else.

Reinstall won’t help. Did you give EtreCheck Full Disk Access in Privacy System Preferences? That gives more information.

Forgot to add: after uninstalling the bad guys, it is necessary to delete and reinstall FCP.

Post a current report and we can likely offer some guidance.

You don’t need to wait for the process to complete to run EtreCheck. It’s looking at your system and your software and reporting its current state. It doesn’t do spin dumps or crash reports except noting that they occurred.
