Bank payment won’t work on iMac

[MellowshipSlinky]

For years we’ve done online shopping etc on our Mac desktop, but all of a sudden when you come to send payment it just spins for eternity.
Doesn’t matter what we try to buy - shopping from Sainsbury’s, tickets, etc.

Jump onto the iPad and it works fine so isn’t our internet.
Doesn’t appear to be any updates available for the Mac either (although it’s quite old).

Anything I should do?
TIA.

No there isn’t.
I have one on the iPad though!

Version is Yosemite 10.10.5
No updates available.

It’s pretty old (2007...)

Safari version is 10.1.2


I’ve cleared cookies in the Privacy setting (manage website data) for TSB, should that help?

I suspect the problem is your browser is horrendously out of date, and Apple are no longer issuing updates to it for OS-X Yosemite. Try installing the latest version of Chrome which does support Yosemite.

Great, thank you.

Thanks all
Have installed Chrome so will see what happens
