In the middle of 2012, Apple changed from the MagSafe 1 to the MagSafe 2 power adapter. They went back to the T-shaped power plug, but made the body of the connector thinner, and wider and increased the length of the strain relief. There was a class-action lawsuit against Apple and their MagSafe connection back in 2011, and Apple replaced older T shape MagSafe 1 adapters with L-shaped units.

However, here at OWC, we still see many damaged or worn-out MagSafe 1 cables with strain relief failure when we purchase used computers for refurbishing. The “L” shaped connection was supposed to help alleviate this issue, and it did somewhat. After repeated misuse, the cable would wear out and short out or even break out of the connector’s body. Still, problems persisted, and users were more likely to pull on the cable rather than the connector of the MagSafe to disconnect it from the computer. Apple changed the shape of the plug to be an “L” shape in 2008 with the release of the new MacBook Air systems to work better with their sleek new body lines, and it had the benefit that it reduced the strain on the cord and made it less likely to separate at the connection to the MacBook Air.Īpple continued using the T-shaped cord connection with the MacBook and MacBook Pro models until 2010 when they switched to having the “L” shaped cord style for all models.

While it was very effective, it did have some shortcomings, the connector would fail at the cable strain relief, and many users were plagued with issues such as this. The original MagSafe 1 power adapters made in 2006-2007 connector used a “T” shaped plug to connect the computer to the power adapter. Over the past 15 years, a few companies have produced them under contract for Apple and they are… Delta: Depending on the model of computer you are using, the size of the adapter would be MacBook (60W), MacBook Pro (60W for 13”, 85W for 15” or 17”), or MacBook Air (45W).Īpple does not actually manufacture its own MagSafe adapters. MagSafe adapters of both generations come in three wattage output sizes (and three physical sizes) – 45W, 60W, and 85W. If you had a newer model MacBook Pro with MagSafe 2, you had to be able to adapt that connector to use the display properly. This was very handy since Apple also included MagSafe 1 charging capability with their 27” Apple Cinema Display and 27” Apple Thunderbolt Display.

MacBook Pro (Retina, 15”) (June 2012 – May 2015)Īpple also made a converter to be able to use MagSafe 1 connections with a MagSafe 2 computer.

MagSafe 2 was in use from June 2012 until June 2017. MagSafe 1 was in use from January 2006 until June 2012. MagSafe adapters came in two different types – MagSafe 1 and MagSafe 2. It’s likely that’s where Apple came up with the idea for MagSafe, since MagSafe is derived from a magnetic power connection that deep fat fryers used to keep dangerous accidents from happening in the kitchen, and it certainly has saved many a MacBook in its history from damage. It’s rumored that Steve Jobs himself used to visit department stores and walk the aisles looking at the different manufacturers and their industrial designs. Or, worse yet, a broken power port on their laptop and having to replace or repair it from a simple mistake like forgetting to unplug when getting up and feeling that terrible “YANK” as the cord was pulled out of the wall or computer. I am sure that many computer users remember the pain of a bent power cable. It held them firmly, providing a secure connection to the computer. But in case of an accidental disconnect, such as somebody tripping on a cord, it would break away from the body of the computer and safely disconnect without damaging either the connector or the computer if it was pulled off of a desk. Instead of having to physically plug a cord into the computer to charge, its magnetic connection locked the power pins in place. From the beginning, the MagSafe was revolutionary.
