MagSafe 1 is slightly larger, and was introduced in 2006 along with the original MacBook and MacBook Pro. That’s if we ignore the different wireless MagSafe for iPhone (see above) of course! There are three different versions of MagSafe, conveniently known as MagSafe 1, MagSafe 2 and MagSafe 3. “The surface area of two magnetically attracted halves determines the number of magnetic flux lines and therefore the holding force between them because the holding force is proportional to the contact area between the two magnetically attracted halves.” These clasp together and power is thus provided to the laptop.

The connection between a MagSafe adaptor and the Mac laptop is made using two magnetic halves. This is instead of the more usual clasp/socket technique of inserting the cable inside the laptop. MagSafe on the Mac works by connecting the power socket to a Mac using magnets. The MacBook Air then gained MagSafe charging in June 2022. While still charged via USB-C, the port gained the magnets necessary to make detachment and attachment easy. Then, in 2021, Apple brought MagSafe back to the MacBook with the launch of the 14-inch and 16-inch MacBook Pro. For some time all Mac laptops were charged via their USB-C or Thunderbolt ports. MagSafe was temporarily discontinued on Macs in 2019 when Apple stopped selling the 2017 model of the MacBook Air. The presence of MagSafe on an Apple laptop was a given right up until Apple announced the 12-inch MacBook with no MagSafe adaptor in 2015, choosing instead to power it via a USB-C cable, instead of MagSafe. The MagSafe connector was loved for the fact that it softly disconnected from a Mac if the wire was yanked out, leaving the Mac safely on the desk while only the wire drops to the ground.

Hello again - first, you've answered none of my previous questions - please respond: 1) Go to the first link I provided and tell us which specific laptop you own (there are over a dozen listed) 2) Can you download Coconut Battery to the computer or is the machine completely DEAD regardless of its attachment to a charger and 3) Is the Apple Store (shown in my previous post) in your city still open?Ĭoncerning whether your MacBook is 'broken', the possibilities are too numerous to make a guess - here is a simple chain of potential problems (which may be one or several): AC Power from you wall socket -> Charger (multiple levels) -> Connection to the laptop (and charging electronics) -> Battery -> Computer other than battery - there is simply no way to provide you a definite answer - I'm 5,000 miles away - go to your Apple store, if possible?įinally, Apple's chargers come w/ L-shaped & T-shaped connectors - there are 5 pins (see diagram below from Wiki) - the outer pins are ground, pins 2 & 4 carry power, and the middle pin is for information exchange - the surrounding gray portion is magnetic the outer aspect of the connector carries no charge.

'My MacBook doesn't work', I'm assuming that the machine does not work whether on or off the charger - correct? If so, hard to give advice - I was going to suggest obtaining the free Coconut Battery App which gives stats on the status of your battery (see image below from my MBPro which has a fairly new replacement battery), such as designed capacity and cycles used - BUT, if you can run this app on your MacBook, then provide us w/ the information shown (or a screen capture).įinally, if indeed the computer is 'dead', then have you tried to visit a repair shop or an Apple Store (there seems to be one in your city - second pic below) - Apple could run diagnostics (but don't be surprised if they refuse due to the age of your machine) - maybe time to look for a new laptop? Good luck - Dave

Hello and welcome to the forum! Looking on EveryMac in their 'Lookup' section, the model number above shows MacBooks introduced from 2006 to 2009 (check the link and tell us the specific one) thus, you have an 'old' laptop and the battery, as already suggested, may be the problem (unless replaced) also, I would suspect the computer to work w/ a proper charger attached, so a couple of issues.įrom your last statement above, i.e.
