A MacBook Pro RAM Upgrade ranges anywhere from 512MB 667MHz in the Original MacBook Pro to 16GB 1600MHz in the 2012 Model 9,2. Some MacBook Pro Memory Upgrades can be tricky. The "Original" MacBook Pro, for example, has a silver bezel around the screen, and runs DDR2-667 memory. The maximum memory that can be installed is 4GB; however, only 3GB will be addressed. Installing 4GB of RAM utilizing the 2x2GB configuration is the best configuration for this machine as it will give your machine a slight boost from the 4th GB, and you will enjoy a boost from installing matched pair modules.
The Processors
With the latest versions of the MacBook Pro you can find on the shelves today, you will find a few different options with the processor. The machines today have a 2.5 GHz dual core Intel Core i5 processor that has a 3 MB shared L3 cache, as well as a 2.6 GHz dual core Intel Core i5 processor. You also have the option of an i7 processor that's a bit faster. They offer a 2.4 GHz quad core Intel Core i7 Ivy Bridge, as well as a 2.7 GHz i7 Ivy Bridge processor.
Again, with the variety of MacBook Pros on the market right now, you will have quite a bit of variety here. The latest Retina models of the MacBook Pro feature SSD hard drives rather than traditional SATA hard drives. The 13" can come in a number of different options, with the standard being 128GB for the 2.5 GHz and 256GB for the 2.6 GHz. With the 17" computer, you will have 256GB for the 2.4 Ghz or 512GB for the 2.7 Ghz.
The latest versions of the MacBook Pro, the Retina Display models, are not able to have RAM or the hard drive upgraded. Thus, it is important for buyers to make sure they are choosing a machine that is going to have the capability to work for their needs until they are ready to buy a new one.
The batteries on the MacBook Pro are able to offer up to 7 hours of wireless web time, and this is true of all of the different Retina Display models out now. They also are able to offer up to 30 days of standby time. The 13" model has a built in battery – 74-watt –hour lithium polymer battery. The larger 15" model has the same type, only it is a 95-watt-hour battery. The 13" also has a 60-watt MagSafe 2 Power Adapter and port, while the 15" has a 85-watt version of the same.
As for the power, the MacBook Pros have a line voltage of 100V to 240V AC, and a frequency of 50Hz to 60 HZ.
You will find a number of connections for your MacBook Pro. They all include the MagSafe 2 Power Port, which is where the magnetic connector that charges the machine will go. They also offer two USB 3.0 ports, two Thunderbolt ports, dual microphones, an SDXC card slot, and an HDMI port. In addition, they have a headphone port. You will be able to use the iPhone headset with a microphone for this port as well.
In addition, they have Wi-Fi capabilities with 802.11n wireless networking capabilities, as well as Bluetooth 4.0.
All MacBook Pros come preinstalled with the latest OS X operating system. In current MacBook Pros, that is Mountain Lion OS. Even though the machine comes with this OS installed, this is not the only one you can use with the laptop. It is also possible to use Windows on the MacBook Pro, as it uses Intel x86. You are able to install 32-bit as well as 64-bit versions of Windows XP, Vista, and 7. However, while it is not "official," it is also possible to install other x86 operating systems, including the popular Linux.
