If it’s a genuine Apple charger, you should be fine, those are universal. If it’s not (and it’s not unheard of for counterfeit items to be sold on eBay), all bets are off. See for instance Ken Shiriff’s teardowns of iPhone chargers to see what enormous differences there can be among charger designs and their safety: ...

Apple Charges are universal (worldwide) Every charger has a label that has to say something as following: 110-220 Volt (or 100-240 Volt) 50- 60Hz. Then it is a Universal charger. FYI: The USA system is 110 Volt 60 Hz while the European is 220 Volt 50 Hz. And Apple charger covers both systems. And you do not need a expensive converter or some traveler ...

The caffeinate command line utility (built in, at least in Mavericks and Yosemite) does just this. "man caffeinate" for more

Take a single Time Machine backup, just in case. When you wipe the laptop, use the Time Machine drive to selectively (manually) restore certain items. Information and files related to application licensing will most often be located in: ~/Library/ ~/Library/Application Support ~/Library/Preferences

the sluggishness may come from newer O/S upgrades that have degraded the performance of the computer. I say this because Mac O/S rarely has the "bitrot" issues that plague Windows, making it necessary (if not just advisable) to reinstall the O/S every 3-4 years. So if you have kept up with the O/S upgrades that may actually be the culprit. There are also ...

There will be no problem, I've been using mine (both the 85W and the 60W) both in Europe and the U.S. just by swapping the plug, never had any issues.

In case anyone is reading this now, the 13" Retina screens can be put into a higher-resolution scaled mode 1680 x 1050 mode which is still readable. It's the same as the Macbook Pro 17" I used to use, just in a smaller space. This is ample width for using XCode or other IDEs

One way to accomplish this would be to test the performance in a virtual machine configured to represent a more limited processor. Assuming you're using a Mac which came with a pre-installed OS, you'll probably need to buy an additional Mac OS license, but the virtualization can be done for free with VirtualBox, or for a moderate cost with Parallels or ...

There is no safety difference whatsoever. The 3 pin grounded cable goes to a 2 pin connector which then plugs into the adapter. This means that the grounding is not even connected so there is absolutely no difference safety-wise. Main reason is for those places where you have to rotate the wall plug to insert, or you need to insert a grounding pin in to ...

I found problem. The problem seems to first exhibit itself during graphics-intensive tasks like playing games or high-definition video, or running the CPU hot. The display ends up distorting, or going entirely blank, and while reboots make the problems go away for a short period of time, they almost always return later. After the graphical glitches start, ...

Is FileVault (full disk encryption) enabled for your main disk? Because it was in my case, and it proved to be the cause of this error. You can find this setting in System Preferences -> Security & Privacy -> FileVault. During the installation of OS X Yosemite, you can choose if you want to enable FileVault, and it's turned on by default. It's the first ...

Apple sells a "World Travel Adapter Kit" that fits most of the Apple chargers sold in the last five or so years. The kit also includes a USB charger that fits each of the adapters. You can use any Apple charger that fits this kit, anywhere in the world.

Disconnect everything from the Mac and then power it off. Perform recovery according to these steps. http://support.apple.com/en-us/HT4718 If that fails, then you may need support from Apple to determine the version of OS X that shipped with the Mac so you can restore that and start over/restore from a backup once the hardware is known to work. Or it ...

A Macbook Pro USB port will supply power to devices if the Macbook is on or asleep. It will not do so if the Macbook is powered off, completely shutdown. See here for more details on how the power is supplied, it can get tricky: http://support.apple.com/en-us/HT4049

Disconnect from the network and reboot the Mac. Then see if the process can clean itself up. Assuming it is under control, open system preferences and turn off all automatic checks under the app store pane. At that point you can reconnect to the internet and see if things are solid before opening the App Store app again.

You will need to use a computer with 10.6 (snow leopard) or earlier if you want to run that software on a Mac. Maybe a friend has an older computer you can borrow. Or maybe it will work on a computer lab machine. Other Options: 1) Try running it on a Windows PC (I'm guessing backwards compatibility will be better) 2) Virtual Machine. It looks like Snow ...

I remember asking the guy at the Apple store this very question back when I bought my black MacBook 13" back in 2007. From what he said and from what I've read over the years regarding battery health, most of what Apple have stated on the page you referenced is applicable to you. If I could offer some more advice, it would be this. Cycle your battery at ...

GrandPerspective is a great app to visualize the files taking up the most space on your Mac. Next time you want to delete a file, use GP to scan your computer before and after you empty the Trash, and see what's still taking up space.

I had a similar issue with a client's laptop trying to install NI Kontakt Ultimate 10 (~ 330 GB) on a SSD with 400 GB "free" space. Probably TimeMachine local snapshots is enabled on your Mac. Local snapshots are basically backup files stored on your local hard-disk (as opposed to regular ones stored on the external TimeMachine volume). This is a useful ...

You could make a backup using time machine to an external harddrive. When that is completed shut down your mac and reboot it with the alt-key pressed. You will get in a menu where you can choose which drive you want to startup from. When you have os x 10.10 installed you will see the drives "Macintosh HD" amd os x 10.10 recovery. Start you mac from the ...
