If I could upgrade, that would be simple. The computer is too old.

Well and this is not a flippant remark

Time to shop for something newer or New

Explore the Apple Trade-In  Process where the Value of the exiting device could be used against the cost of a new Apple Computer

Notation - Some devices and depending on the computers age may have little to no value at Trade In time.

But at least the device will not arrive to the Land Fill Site and be recycled in a responsible way by Apple

Or Shop Refurbished Apple computers at an Apple Reduced Cost

Yes, I have used this several times over the years

You may want to consider used or refurbished Macs from http://www.macsales.com/

macOS Sonoma is compatible with these computers - Apple Support

So that would mean a 2018 Mac Mini is probably going to be the cheapest option available to you.

To achieve what you want and using " HMRC Basic Tools " ?

According to " HMRC's Basic PAYE Tools " website

macOS 10.15 Catalina was released October 7, 2019 in 2025 ?

Supported operating systems

The following operating systems are supported:

• Windows 10 and 11
• macOS version 14 ‘Sonoma’ and 15 Sequoia’
• Ubuntu Linux version 24.04 LTS and 24.10

sounds like HMRC is telling you to get a new computer.

http://www.express1040.com/ will scan your statements that are PDF of various forms directly into the right part of the of the tax system. You only pay for State tax filing a nominal fee that is under $20 a year. I'm just a happy customer. Works all web based. I used it on Firefox on Monterey which is also available for Catalina.

Have you tried the HMRC website itself directly?

Have you contacted HMRC to let them know your difficulty?

Does HMRC have a system set in place you can use at libraries to file taxes or municipal centers?

It would seem evident what needs to be done - No.

If this computer does not Qualify to upGrade to macOS 14 Sonoma or macOS 15 Sequoia

What do you see would be to solution ?
