If anyone eventually updates and doesnt have problems, please let us know. I haven't touched the update because I know there are problems. My machine is only just about working properly after the previous update and I really dare not do this one. I also have a PC and due to the updates that have been put out by Mac, I tend to use the PC for most of the time now. Don't know who is supposed to check this stuff works properly, but at the moment, its just sitting on the back burner and I guarantee I won't be updating any time soon.

You are very welcome

More importantly is the previous Owner " Stepped Up " and did the right thing

An aside to all this of you allow me.

Having upgraded 1 machine from macOS 11 to macOS 12 to macOS 13 to macOS 14 and finally to macOS 15 - No issues

Upgraded 1 machine from macOS 13 ro 14 and to 15 - Not Issues

UpGraded yet another machine from macOS 14 to 15 - no issues

The latest M4 Mac Mini from Sequoia 15.0 to every additional update and sitting a Sequoia 15.3.1

The only real problem I have is which machine to use at any given time

I really do not understand why some people have issues.

Guess I am just " Lucky "

I think not
