My Mac (desktop)
I understand that the program I am using (captain) is out of date. The blog shows a series of system updates (called other things) which I never saw or understood that I needed to change to.
Also, it keeps telling me that some browsers won't work.
1) I do not know if this means I should update one program at a time: 11.0, 11.2. 11.4 etc... until I am fully up to date or if I should skip to the most recent (that sounds scary - like some items will be missed or interrupted).
2) Do these programs apply to any mac or only those after a certain year (like with a bigger memory or faster something.. .)
3) Does it cost anything and how do I backup my computer to an portable g-drive before I make any changes?....
I am at a loss and I wish I could say I knew more, but I don't and please don't judge if you think this information should be simple or self-explanatory. I just need solid guidance without any tricks to make me feel inferior or which will not produce the desired result, Please (w/sugar).
Also, I do not know what Java is or does and why it's disallowed or whatever - so I cant tell if I need it still or not.
