I have been using an Mac since I bought a Macbook in 2008. We did buy a new PC a few years ago because every now and then we come across something that requires a PC, but neither my wife or I use it very often, since she began using a Mac a few months before I did. In 2011, I bought an iMac, which is the computer that I used most of the time now. I still have the Macbook and, because my iMac is so big and heavy, I sometimes take the Macbook when I'm traveling, since it is a 13-inch laptop that is easier to carry around. When I used PCs, it seemed that every couple of years, Microsoft would come up with a new version of Windows that wouldn't work well on my old computer, so I'd have to buy a new one, or programs that I needed would come out with upgrades that required an upgrade of Windows. I could upgrade my version of Windows only a few times before a new version would come along that would slow things down too much for my PC. I haven't seen that happen with my Macs. Upgrades to the Mac OS are either free or only a few dollars, and they either make the machine run better or the only change is whatever new stuff they might have added to the OS. Upgrades to Mac apps or programs are also usually free or inexpensive except for programs that also have versions for a PC. I haven't had very many problems with my Macs. My Macbook works as good now as it did when it was new. I have doubled the RAM in both my Macbook and my iMac because they usually come with very little, for some reason. However, lately my iMac has been acting up. A Mac has a beachball looking thing that spins around when the computer is trying to do something that takes a while. I think I can remember that Windows has something similar but I don't remember what it looks like. Anyhow, there are times when I'll be typing something into a text editor or somewhere, then I'll look up and see that it had entered only the first few words of text, and the beachball is spinning around. Plus, when I try to shut the iMac down, sometimes the menu bar at the top will disappear and my desktop will disappear, but the app shortcuts at the bottom remain, and it never shuts off. The beachball isn't spinning so it's not trying to do anything. In fact, I can even open up any apps that are included in the shortcut bar. But in order to shut the computer off, I would have to force-close it. We drove to Portland so that I could bring it into the Apple Store, as they told me they could fix it. But when I got there, they ran it through diagnostics and told me that it was definitely not a hardware problem. Only the fix that they had in mind was to wipe everything out and reinstall the OS, and they wouldn't mirror my data for me so that it could be reloaded. Sorry, but I have too much stuff on my computer. Most of my apps can be easily reinstalled through the app store but I have several that I use all the time that I bought outside of the app store, and my installation keys are stored in a variety of places, including old emails, in text folders, in my Notes app, and who knows where else, and I am sure to come across something that I need that I can no longer use. Then there are years worth of data, web site creation files, photos, images, etc. I don't want to spend days just trying to get my computer back to where it was before, minus the spinning beachball and the problem shutting it off. So I dropped it off at a third-party computer service place in Bangor, since they will mirror my drive for me, and add everything back on top of the new installation of the OS. If it's a software problem, as Apple insists, then it has to be in the OS because it occurs after I have closed everything else down. That should fix everything. Meanwhile, I am stuck with my tiny little Macbook.
