to Apple or an authorized service provider to have both GPUs replaced for free. The repair program ended on May 30, 2018. Customers who owned Mac Pros with FirePro D300 GPUs also complained about problems, but those GPUs were not included in the repair program until July 2018. Customers with FirePro GPUs not manufactured between those dates have complained of issues including overheating and thermal throttling. It is believed Apple has not enabled a satisfactory cooling fan profile in order to properly reduce heat from the system. Users have had to resort to using third-party apps to manually increase the fan speed to prevent the GPUs from overheating. Lattice tower or rack (2019) In April 2018, Apple confirmed that a redesigned Mac Pro would be released in 2019 to replace the 2013 model. Apple announced this new Mac Pro on June 3, 2019 at the World Wide Developers Conference. It returns to a tower design similar to the Power Mac G5 in 2003 and the first-generation model in 2006. The design also includes a new thermal architecture with three impeller fans, which promises to prevent the computer from having to throttle the processor so that it can always run at its peak performance level. The RAM is expandable to 1.5 TB using twelve 128 GB DIMMs. It can be configured with up to two AMD Radeon Pro GPUs, based on RDNA 1 architecture, which come in a custom MPX module, which are fanless and use the chassis's cooling system. Apple's Afterburner card is a custom add-on, which adds hardware acceleration for ProRes codecs. Similar to the second generation, the cover can be removed to access the internals, which features eight PCIe slots for expansion, making this the first Mac with six or more expansion slots since the Power Macintosh 9600 in 1997. It can also be purchased with wheels and in a rack mount configuration. Feet and wheels are not stated by Apple to be user-replaceable and require sending the machine to an Apple Store or authorized service provider, though tear-downs show the feet are simply screwed on. It was announced alongside the Pro Display XDR, a 6K display with the same finish and lattice pattern. The 2019 Mac Pro is capable of Lights Out Management. It is also the first Macintosh computer to feature 10 Gigabit Ethernet ports equipped as standard in all configurations. After initial reports that the
