How do I get rid of Catalina?

I updated my MacBook Pro 13 inch mid 2012 to Catalina because it was struggling with many websites.

Catalina is horrible. My computer is s.l.o.w.

Can I downgrade to Mojave? Mojave will not download successfully from the appstore. It's probably because Catalina is is horrible and slow.

Before you downgrade you might want to know why your MBP is running so slow on Catalina. Download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.


Copy the report



and use the Add Text button to include the report in your reply. How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report


IMPORTANT:


Before running Etrecheck assign Full Disk Access to Etrecheck in the app's Privacy preference pane so that it can get additional information from the Console and log files for the report:



ALSO IMPORTANT:



Then we can examine the report and see if we can determine the root of the problem.

You have three things working against you here:


1 - WebRoot. There is no reason to ever run any "cleaning", "optimizing", "speed-up" or anti-virus apps on your Mac.  This user tip describes what you need to know and do to protect your Mac: Effective defenses against malware and other threats - Apple Community.   


Uninstall WebRoot according to the developer's instructions: SecureAnywhere Mac You want to know how to uninstall.


2 - You're only running 4 GB of RAM. That's the bare minimum to run the current operating systems. You model can utilize up to 16 GB of RAM. I recommend you get a couple of 8 GB RAM modules from Crucial.com or MacSales.com. You will definitely see improvement.


3 - Time since boot: About 7 days: one should boot more frequently, at least 2=-3 times a week. With an SSD hard drive the boot time is not very long at all. Rebooting cleans out temporary system, cache and memory swap files. Doing so will help with performance and memory usage.

    4 GB RAM - Upgradeable
        BANK 0/DIMM0 - 2 GB DDR3 1600 
        BANK 1/DIMM0 - 2 GB DDR3 1600 
...
    Swap Used: 4.56 GB <<<--- that is a lot of paging to disk

More RAM. Your Mac can support 16GB of RAM. With 4.56GB of memory paged to disk, you are spending a lot of time waiting for code and data to move in and out of the small amount of RAM you have.


    disk0 - SanDisk SDSSDA240G 240.06 GB (Solid State - TRIM: No)

Enable TRIM

https://blog.macsales.com/31619-how-to-execute-trimforce-command-with-your-owc-ssd/

https://www.imore.com/os-https://discussions.apple.com/docs/DOC-8841

SSDs require pre-cleared storage cells when you do a write. TRIM allows the file system to tell the SSD when you have deleted a file, so that the SSD can add that file to the garbage collection queue for pre-clearing. Without TRIM all your deleted files still look like data still in use to the SSD, and that gives the SSD a lot less storage cells to pre-clean and give to you when you write. And because you are doing a lot of RAM paging to/from disk, you are asking the SSD to do even more writes, requiring more pre-cleared storage cells.


Remove the 3rd party anti-virus

Kernel Extensions:
    /Applications/Webroot SecureAnywhere.app
        SecureAnywhere.kext (Webroot Software, Inc., 9.0.10 - SDK 10.14)

macOS provides ample protection. Please read:

Effective defenses against malware and other threats

https://discussions.apple.com/docs/DOC-8841


    Other processes 308.17 % (?)

I do not know what "Other processes" are, but you can use

Applications -> Utilities -> Activity Monitor -> View -> All Processes

to monitor CPU usage and that should give you an idea.


NOTE: If one of the high CPU processes is 'kernel_task', this is the heart of macOS, as well as whatever the SecureAnywhere.kext kernel extensions is doing inside your macOS kernel. So high kernel_task numbers can very well be your anti-virus package.

This is the report (with some personal stuff pulled out). The battery is on my to do list. One thing that worries me is the thing called configuration profiles present. That seems to indicate possible adware or something worse. I wonder if that is HotSpot Shield, a former vpn I used, because it shows up on user profile, and I don't know what it would do that.

Is Catalina incompatible? I’d like for my Mac not to be a brick. But i


f it’s incompatible can I downgrade to Mojave to at least have somethi
