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 вЂњTвЂќ 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 areвЂ¦ Delta: Depending on the model of computer you are using, the size of the adapter would be MacBook (60W), MacBook Pro (60W for 13вЂќ, 85W for 15вЂќ or 17вЂќ), or MacBook Air (45W).ДЄpple does not actually manufacture its own MagSafe adapters.

MagSafe adapters of both generations come in three wattage output sizes (and three physical sizes) вЂ“ 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 27вЂќ Apple Cinema Display and 27вЂќ Apple Thunderbolt Display.

MacBook Pro (Retina, 15вЂќ) (June 2012 вЂ“ May 2015)ДЄpple also made a converterВ 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 вЂ“ MagSafe 1 and MagSafe 2. ItвЂ™s likely thatвЂ™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. ItвЂ™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,В 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 вЂњYANKвЂќ 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.В 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.

Apple has dropped FireWire 800 from most of its portable Macs to save space but with Thunderbolt you can simply pick up an adapter and carry on using any FireWire 800 devices you have.From the beginning, the MagSafe was revolutionary. ThereвЂ™s a huge ecosystem of FireWire 800 devices so support for them is still very much required. USB 3.0 however completely obliterates FireWire 800 and, as such, the latterвЂ™s now fast becoming a legacy connection. Compared to someone who is doing a constant 30MPH, theyвЂ™ll be much slower reaching the finish line. Imagine if someone was driving 50MPH for a few seconds then stopping, then 50MPH and stopping again. FireWire 800 is a constant rate - it constantly sends data at 800Mbit/sec. It sends a lot of data at its highest speed before stalling and then repeating it again. USBвЂ™s transfer rate is know as a burst rate. If USB 2.0 was 480Mbits/sec and FireWire 800 was 800Mbits/sec, then surely that would make FireWire 800 just under twice as fast? Actually, FireWire is a lot faster than USB 2.0. LaCie are a popular manufacturer of FireWire 800 storage devices USB 3.0 cables are noticeably different and you can generally tell if a device is USB 3.0 simply by the blue USB connector it will have. Your printer or keyboard will work in exactly the same way.

Not only can you use a USB 2.0 device with a USB 3.0 Mac but a USB 3.0 hard drive will even work with a USB 2.0 Mac. USB 3.0 is still just as versatile and fully backwards-compatible with older USB devices. Some USB 2.0 drives come with a second USB cable that simply has an power connector on the other end if your Mac canвЂ™t provide enough power to the drive. It can also provide more power to devices. Currently, itвЂ™s only missing from the Mac Pro. It first appeared on Macs in 2012 when Apple introduced the new Retina MacBook Pro and updated MacBook Air range. USB 3.0 theoretically tops out at 5Gbits/sec - around 10 times quicker. USB 2.0 can top out at a theoretical 480Mbits/sec.

USB 3.0 is a huge improvement over USB 2.0 as itвЂ™s much, much faster.

USB 3.0 is the latest iteration of the Universal Serial Bus format.
