Apple has officially confirmed that the first-generation Magic Keyboard is compatible with the new 12.9-inch iPad Pro. However, the Magic Keyboard might not close completely as the new 12.9-inch iPad Pro is slightly thicker. This essentially confirms that the recent report that made rounds on the Internet saying that the new iPad Pro is incompatible with the older Magic Keyboard was not correct.
Older Magic Keyboard will work with the new 2021 12.9-inch iPad Pro
Apple has posted a new support webpage update that explains how to connect and use a Magic Keyboard with iPad Pro. The company has added an explanation that the iPad Pro is functionally compatible with the first-generation Magic Keyboard, but due to being 0.5mm thicker, it might cause issues with closing the keyboard, especially if a screen protector is used.
The first generation of the Magic Keyboard (A1998) is functionally compatible with the new iPad Pro 12.9-inch (5th generation) with Liquid Retina XDR display. Due to the slightly thicker dimensions of this new iPad Pro, it’s possible that the Magic Keyboard may not precisely fit when closed, especially when screen protectors are applied.
Apart from the slight increase in thickness for 12.9-inch iPad Pro, likely due to the mini-LED Liquid Retina XDR display, there are no other changes in dimensions which means that the magnets should align well between the keyboard and iPad.
The new Magic Keyboard for 12.9-inch iPad Pro not only precisely fits with the tablet, but is also available in a new white color. The keyboard is also backward compatible with previous-generation iPad Pro models from 2020 and 2018.
This issue does not apply to the new 11-inch iPad Pro as its thickness and dimensions are completely unchanged.
The report that the older Magic Keyboard will not work with new 12.9-inch iPad Pro had emerged a few days ago from iGeneration website, as it reported that the keyboard will not work at all.
