Realistically most Mavericks-capable systems with built-in displays, other than the early aluminum iMacs and Santa Rosa Core 2 MacBooks, have LED back-lighting which isn't going to noticeably dim with age or be affected by on/off cycling. If you're driving a CRT/plasma/CCFL-LCD monitor then you have option of increasing the lifespan of the display phosphor ...
That $600 rate is less than Apple charges for a liquid damage overhaul at the repair depots. That repair is around $900 for the Air and 13 inch models and $1200 for 15 inch models. Since the keyboard is integrated within the housing, it's like taking the engine, chassis and all parts out of a car and building it up new in a new frame. The labor time and ...
The old days keeping as much RAM free as possible are gone. The new RAM management from OS X, use all available memory, but also manages it so that you get maximum performances. If you look in the Activity Monitor- memory, you will see things like Memory Pressure, Compressed among other information.
You'd probably had a lot of compressed memory in your 4GB days. Now, with 8GB, you're not nearing your limit yet so your computer doesn't see a need to compress anything. If you ever hit 7.99GB, you'll start building up compressed memory again. (I recently went from 4GB to 10GB, and I'm currently using 9.97GB but only have 7.1MB of compressed memory.)
There are potentially a few things happening here. When a computer runs out of available RAM it starts swapping or paging data out of RAM to files on your hard disk. When your Mac was previously saying that it was using 3.98GB of 4GB it could also potentially have had a lot more data loaded but part of it swapped out to your hard drive. You can find these ...
I think of it as the "lawyer's light bulb", or the equivalent of "objects in this mirror may be closer than they appear" [which I actually thought was a joke when I saw it for the first time] Leaving a light bulb on 24/7 will shorten its life, as it won't last as many years compared to if you just used it an hour a day. This is, however, a 'fake' analogy, ...
The Kanex USB 3 adapter would not work with USB 3 external hard drives that I bought it for so I had to return it. Make sure the place you buy it from has a decent return policy.
For all it's worth, I have ran the command line in Terminal with a few devices. iPhone 4: iPhone: Version: 3.20 iPad 2: iPad: Version: 2.10 I have a 3GS somewhere but I can't find right now. I'll edit my answer if/when I find it. My wife has a iPhone 4S and a friend has a 5, I will try to also update once I get to run it.
