how to install safari 11.0 into iMac OSX 10.9.5
I would like to install Safari 11.0 into my iMac (OSX 10.9.5).
Safari now is 9.1.3.
My proof reading of a manusript for publication runs only on Safari 11.0.
I have just accidentally installed Safari 12.1.1 free from a sight but when I try to run it the computer rejected by saying that it is from an unknown site. I was my mistake in two parts; it must be 11.0 exactly to run the proof and I should not have trusted the site. Now I don't know how to uninstall it. It is another story.
If I may go back to the important question. Can I install Safari 11.0 safely ?
I have plenty of hard disk space about 850 GB out of 999 GB.
I would appreciate your advice and guidance.
