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 ...

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.

No, your MacBook model cannot be upgraded to a version later than Mac OS X 10.6.8 because of restrictions imposed by Apple. It is highly likely that even if you could install a later version, your system would run unstable and/or slow. Regarding upgrading your hardware, yes, it's possible, but I'd say you'll have a hard time finding parts (other than RAM, ...

Hold alt during startup, you will then be able to boot from something called "recovery partition". When that is booted, in the menu select "disk utility" and try to repair disk and/or volume.

This is normal behaviour for Yosemite for users with FileVault enabled (i.e. Your Mac's primary disk is encrypted). The authentication process is done earlier because without authorisation from the user the OS cannot access the rest of the disk. This is a good thing, and I think you are (mostly) mistaken that it takes longer to boot up — since now you are ...

Your product is still under Apple warranty. Best course of action is to bring it to Apple Store for service. It sounds like hardware problem anyway. Meanwhile you could try some troubleshooting, like start in safe mode and see if it works. Next try logging in as another user to see if it is your user profile related. Also you could delete your airport ...

You could use BootCamp, but that would require you to buy Windows. The next best thing I can think of trying is Wine, which can run (some) Windows programs on a Mac. To check if your program has been tested to work under Wine, check the WineHQ app database. The database may not include a test of your program, so try running your program using WineBottler ...

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 ...

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 ...
