MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache[40] and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.[41]
Nov 5 Video Freezes When Tabbed Out Yesterday I "upgraded" to Mojave. While I am playing the game, if I tab out for any reason--be it with the 4-finger swipe to another tab, or any of the launch-type buttons--the game video stops working in the background, and the Beach Ball spins. The audio continues to work, and it seems like the game continues to play, as I often tab out between flight paths, and when i reboot the game, I am at the destination flight path. 15" Late-2014 Retina MBP 10.14 Mojave 2.5 GHz Intel Core i7 16 GB 1600 MHz DDR3 NVIDIA GeForce GT 750M 2048 MB 512GB SSD EDIT: Playing in Windowed Fullscreen Mode.Moleqular24 Nov 5
