Check out MacBook Pro, iMac Pro, MacBook Air, iMac, and more.Mac Pro is a series of workstations and servers for professionals that are designed, developed and marketed by Apple Inc. The cost of replacing these depends on where you're based, where you purchase from, and whether you buy a new, used or refurbished logic board.If the above troubleshooting does not stop iPhoto from freezing after editing photos. The only logic boards guaranteed as compatible with the Mid 2012 13' Unibody MacBook Pros are either the 2.5Ghz (core i5) as you have now or the 2.9Ghz (core i7) unit also used for this model.Reviews initially were generally positive, with caveats. Thunderbolt 2 ports brought updated wired connectivity and support for six Thunderbolt displays. It had up to a 12-core Xeon E5 processor, dual AMD FirePro D series GPUs, PCIe-based flash storage, and an HDMI port.The iMac, Mac Mini, MacBook, and MacBook Pro had moved to an Intel-based architecture starting in January 2006, leaving the Power Mac G5 as the only machine in the Mac lineup still based on the PowerPC processor architecture Apple had used since 1994. In June 2005, Apple released the Developer Transition Kit, a prototype Intel Pentium 4-based Mac housed in a Power Mac G5 case, that was temporarily available to developers. It has up to a 28-core Xeon-W processor, eight PCIe slots, AMD Radeon Pro Vega GPUs, and replaces most data ports with USB-C and Thunderbolt 3.The first generation of the Mac Pro featured an aluminium case that was derived from that of the Power Mac G5, with the exception of an additional optical drive bay, and a new arrangement of I/O ports on both the front and the back.Apple said that an Intel-based replacement for the 2003's PowerPC-based Power Mac G5 machines had been expected for some time before the Mac Pro was formally announced on August 7, 2006, at the annual Apple Worldwide Developers Conference (WWDC).
Check 2012 Pro For Hardware Issues Mac Pro IsOriginal marketing materials for the Mac Pro generally referred to the middle-of-the-line model with 2 × dual-core 2.66 GHz processors. Apple's previous machine aimed at this market, the Power Mac G5, has up to two dual-core processors (marketed as "Quad-Core"), but lacks the storage expansion capabilities of the newer design. Additionally, the codecs used in these applications are generally processor intensive and highly threadable, which Apple's ProRes white paper describes as scaling almost linearly with additional processor cores. Although the high-end technical market has not traditionally been an area of strength for Apple, the company has been positioning itself as a leader in non-linear digital editing for high-definition video, which demands storage and memory far in excess of a general desktop machine. The Mac Pro is in the Unix workstation market. As such, the name "Mac Pro" was widely used before the machine was announced. Image for screensaver for mac os sierraLike its predecessor, the Power Mac G5, the pre-2013 Mac Pro was Apple's only desktop with standard expansion slots for graphics adapters and other expansion cards.Apple received criticism after an incremental upgrade to the Mac Pro line following the 2012 WWDC. Post revision, the default configurations for the Mac Pro includes one quad-core Xeon 3500 at 2.66 GHz or two quad-core Xeon 5500s at 2.26 GHz each. The system could be configured at US$2299, much more comparable with the former base-model dual-core G5 at US$1999, although offering considerably more processing power. The newer LGA 1366 sockets utilize Intel's QuickPath Interconnect (QPI) integrated into the CPU in lieu of an independent system bus this means the "bus" frequency is relative to the CPU chipset, and upgrading a CPU is not bottlenecked by the computer's existing architecture.The original Mac Pro's main memory uses 667 MHz DDR2 ECC FB-DIMMs the early 2008 model uses 800 MHz ECC DDR2 FB-DIMMS, the 2009 and onward Mac Pro use 1066 MHz DDR3 ECC DIMMs for the standard models, and 1333 MHz DDR3 ECC DIMMs for systems configured with 2.66 GHz or faster CPUs. A 64-bit EFI firmware was not introduced until the MacPro3,1, earlier models can only operate as 32-bit despite having 64-bit Xeon processors, however this only applies to the EFI side of the System, as the Mac boots everything else in BIOS Compatibility mode, and operating systems can take advantage of full 64 bit support. The 2006-2008 models use the LGA 771 socket, while the Early 2009 and later use the LGA 1366 socket, meaning either can be removed and replaced with compatible 64-bit Intel Xeon CPUs. While electrically the FB-DIMMs are standard, for pre-2009 Mac Pro models Apple specifies larger-than-normal heatsinks on the memory modules. With a simple installation of a single FB-DIMM, the peak bandwidth is 8000 MB/s (1 MB = 1000 2 B), but this can increase to 16000 MB/s by installing two FB-DIMMs, one on each of the two buses, which is the default configuration from Apple. Notably, due to its FB-DIMM architecture, installing more RAM in the Mac Pro will improve its memory bandwidth, but may also increase its memory latency. The cards have 4 DIMM slots each, allowing a total of 32 GB (1 GB = 1024 3 B) of memory (8 × 4 GB) to be installed. Various 2.5-inch SSD drive capacities and configurations were available as options.The Mac Pro was also available with an optional hardware RAID card. A case lock on the back of the system locked the disks trays into their positions.The Mac Pro also supported Serial ATA solid-state drives ( SSD) in the 4 hard drive bays via an SSD-to-hard drive sled adapter (mid-2010 models and later), and by third-party solutions for earlier models (e.g., by an adapter/bracket which plugged into an unused PCIe slot). Adding hard drives to the system did not require cables to be attached as the drive was connected to the system simply by being inserted into the corresponding drive slot. A set of four drive trays was supplied with each machine. The hard drives were mounted on individual trays (also known as "sleds") by captive screws. 2009 and later Mac Pro computers do not require memory modules with heatsinks.An example of a Mac Pro's hard drive trayThe Mac Pro had room for four internal 3.5" SATA-300 hard drives in four internal "bays". However, the two extra SATA ports were unsupported and disabled under Boot Camp.The 2008 model had two PCI Express (PCIe) 2.0 expansion slots and two PCI Express 1.1 slots, providing them with up to 300 W of power in total. The extra SATA ports could be put into service through the use of after-market extender cables to connect internal optical drives, or to provide eSATA ports with the use of an eSATA bulkhead connector. It had a total of six SATA ports – four were connected to the system's drive bays, and two were not connected.
