Sorry to read that you're having trouble with the HMRC website. Like many gov (and other) websites the access can be problematic if your computer or browser don't meet minimum requirements.

HMRC website states that Mac compatibility is limited to macOS 14 and macOS 15 - Sonoma and Sequoia.

It also states that Safari is compatible, and I assume only those versions that are supplied with the above OS versions. It also states that Firefox and Chrome browsers are compatible. (I'd pick Firefox over Chrome)

Please see: https://www.gov.uk/basic-paye-tools

As you are running a Mac on macOS 11 Big Sur, it appears that your options are:

• use a newer Mac with a compatible macOS version if possible

• use a PC with Windows 10 or 11 if possible

I would not expect anything less to be compatible with the gov website.

If HMRC support can't help you work out access with your current hardware, then you'll have to change it up or access that info some other way.
