Before updating anything, make a
cloned backup. That's what Carbon Copy Cloner is doing automatically, if you have it running automatically (you have set it to run on a schedule). You can also do this with Superduper, of course. Plus, I hope you are also using Time Machine.
I am running Safari 9.1.2 & should be running a different one?
Yes, you should be using the latest one that will run with El Capitan. That is Safari 11.1.
I have Security Update 2018-001 but should have Security Update 2018-003, yes?
Yes, you should always install the newest Security Update for whatever OS you happen to have.
I have OS X El Capitan, 10.11.6 and should be running OS X El Capitan 11.1, yes?
No. The number after an application (or operating system) name indicate its "age". "El Capitan" started as 10.
11. (it was the tenth major chage to OS X 10) Later, it was updated to 10.
11.
1. Eventually, it was updated to 10.
11.
6. The "10" part has not changed since OS X was invented. The
second number (
11), changes with every major update along with the name (first there were cats: Jaguar, Leopard, Lion, etc., lately it's mountains in California; Yosemite, El Capitan, Sierra, High Sierra, etc.). The
last number indicates how many times the OS X 10.
xx has been updated; OS 10.
11 (El Capitan) ended up with 6 updates, so its last, newest version is 10.
11.
6.
If Gmail works for you, great. Google likes to change colors everyday, sometimes. The changes are purely for aesthetics, Gmail is Gmail however it's spelled or colored. I don't have a gmail account so I can't tell you exactly what the url says, perhaps another member will enlighten us.
All this time --before this issue in my original post above -- and Gmail just magically opened for me.
The question is: How were you
accessing gmail? You can use your Mail.app to access email from any email account you have. I thought that was how you were doing it. If that is true, Mail would automatically show you your gmail messages just like any other email accounts you might have when you started up Mail.
I suggested using Safari (a web browser), since many found Mail had problems with gmail. There is only one "gmail", it is simply an email account. How you view/read/send/store gmail messages depends on what application you use.
Hope that helps.
