Sierra is Spanish for saw and is the name of Apple’s latest operating system OS 10.12.
However, it is not for everybody. It has lots of gotchas that will cost the unwary in time and money.
When you upgrade, it moves your entire Document folder to iCloud. One, the Document folder may contain more data than you have room for in your iCloud account. Two, you will have to always have access to the web to access your data.
The first is not a big problem in that Apple will ask you to upgrade your iCloud space. In my case, 50GB cost me 99 cents a month, automatically taken out of my checking account.
The second can be a really big problem if you either work offline a lot or have limited wireless service. Although I did the upgrade at a coffee shop, I think home usage added a couple of GBs in only a day or two.
My current plan is for 15GB per month and I generally use about 8GB. It used to be rather simple to calculate total prices, but it seems that AT&T is making calculations even more obscure. I gave up for now trying to calculate the cost of unlimited service.
At least I have a nearby AT&T store. I plan to stop by soon for a power-cord gadget. I’ll ask if they can help me calculate the true cost to a significant upgrade.
I think I have all the really important, current “Document” data moved off iCloud and accessible without an internet connection. Now the next question is how do I back that data up to iCloud at my convenience.
P.S. I found out that the latest Epson software for my printer is valid for older operating systems. The list only gives the latest two OS’s but another page shows it would work for several older OS’s. Sigh!
