With Slow Keys on, you need to press a key for a longer period of time for it to be recognized. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer cursor. There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.

From the Input flag menu, choose Show Keyboard Viewer. If the keyboard is connected and detected by OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit or any text application , and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer. Butterfly keys use a butterfly mechanism that's different from the scissor mechanism used for traditional keyboards.

It's called a butterfly mechanism because the components underneath the key resembles a butterfly's wings, with a hinge in the center rather than overlapping like a pair of scissors. Apple swapped to a butterfly mechanism to make a thinner keyboard, which is possible because each key moves less when pressed so less space is needed. The keyboard provides a satisfying amount of travel and stability when each key is pressed, but unfortunately, the thin butterfly mechanism can get jammed up with crumbs, dust, and other particulates, resulting in keys that don't press properly, keys that skip keystrokes, or keys that repeat letters.

Keyboard failure is an in Apple's notebooks because replacing the keyboard requires the entire top assembly of the computer to be replaced, which is not a cheap repair. Which Macs are affected? All MacBook models have the potential to experience keyboard issues because the MacBook was the first machine to get a butterfly keyboard. All , , and and inch MacBook Pro models are vulnerable to failure despite some generational changes Apple has made to the keyboard with different models, which we'll explain more below. It's not yet clear if the models are vulnerable due to component updates. Apple's MacBook Air uses the same butterfly keyboard that's in the MacBook Pro, which has also been the subject of some failure complaints on Reddit and the MacRumors forums, but full data is not yet available as these machines have only been available since October and most complaints have focused on the MacBook Pro.

It is a problem that seems to be related to dust, crumb, and small particulate exposure, with some complaints of heat issues, that affects a portion of MacBook, MacBook Pro, and MacBook Air owners. According to Apple, only a "small percentage" of Mac users have experienced problems with the butterfly keyboard, but anecdotal claims and the high visibility of the issue have resulted in a public perception that most butterfly keyboards fail.

This isn't true as some people have keyboards that are fine, but any modern Mac notebook's keyboard has the potential to experience issues. What has Apple done? Apple in June launched a keyboard repair program for MacBook and MacBook Pro models equipped with butterfly keys, and in May , the program was expanded to encompass all MacBook, MacBook Pro, and MacBook Air machines equipped with a butterfly keyboard, including the new models.

The third-generation butterfly keyboard has a thin silicone barrier behind each key, which was put in place as an ingress-proofing measure to prevent dust from getting in the keys. The silicone barrier on the third-generation MacBook Pro keyboard, via iFixit There was hope following the launch of the third-generation butterfly keyboard that it would cut down on failures, but as a recent report from The Wall Street Journal pointed out, the MacBook Pro is still prone to keyboard issues. Apple in a statement apologized, but did not outline specific repair options or future keyboard plans.

We are aware that a small number of users are having issues with their third-generation butterfly keyboard and for that we are sorry. The vast majority of Mac notebook customers are having a positive experience with the new keyboard. It's possible machines with updated butterfly keyboards will fail less often, but MacBook Pro and MacBook Air owners have still been reporting issues, which is something to be aware of before making a purchase. We haven't heard as many reports about the new keyboards as we have with other older butterfly keyboards, but the problem hasn't been solved entirely and more data is needed to determine the effectiveness of the membrane in the third-generation keyboards.

Keyboard Differences - Switching to the Mac: The Missing Manual, Mavericks Edition [Book]

What about MacBook Pro models? Apple in May debuted new MacBook Pro models with additional improvements to the third-generation butterfly keyboard.

Certain keys on Mac keyboard wont work

The MacBook Pros have keyboards built with a new material that Apple claims will significantly cut down on the keyboard failures that users have seen. Apple has not provided specific details on the material change in the updated butterfly keyboard. According to an iFixit teardown , Apple has made changes to the membrane that covers the keyboard switches. There are also subtle changes to the metal dome over each key switch, perhaps designed to alleviate problems with durability, bounce-back, or other issues.

According to Apple, MacBook Pro and MacBook Air machines that experience keyboard failures will be able to be upgraded with this new upgraded third-generation butterfly keyboard. Older machines that do not use the third-generation butterfly keyboard will not be able to be updated with the technology. What do I do if my keyboard fails? Now that all butterfly keyboards are covered, customers with an affected machine will have no problem getting a fix. Apple is prioritizing MacBook and MacBook Pro keyboard repairs and requiring Apple retail staff to perform the repairs in store rather than sending machines off to a repair facility, which takes days.

Apple is now aiming to offer next-day turnaround time MacBook and MacBook Pro keyboard replacements, which should improve the inconvenience of repairs. In some cases, if you get a large crumb underneath a key, a key will feel locked in place. There are occasions where you can wiggle the key to break up the crumb and get it working again, and Apple also recommends cleaning out the keyboard with compressed air.

What will Apple do next? Public sentiment about the butterfly keyboard and the overall performance of Apple's notebooks is growing worse, which is not surprising as Apple has been releasing machines with keyboards that can potentially fail since Apple made an effort to improve the situation with the MacBook Pro models, but given the negativity toward the butterfly keyboard, Apple could be planning on more significant design changes for future MacBook Pro models.

Good news: both the new MacBook Air and the new entry-level inch MacBook Pro models introduced today have the same third-generation butterfly keyboard design with an updated material as the higher-end MacBook Pro models introduced in May, we've confirmed directly.

Apple apologized for the issues in March, but it continues to insist that a "small percentage" of customers are affected. Apple has not elaborated on the new material, but the repair experts at iFixit completed a teardown of the MacBook Pro and discovered a "subtle change" made to the silicone membrane covering the keyboard switches. Whereas the membrane in the MacBook Pro is "semi-opaque" and "feels like silicone," iFixit said the cover in the model is "clearer and smooth to the touch. Despite the new material, Apple has added all MacBook Air and inch MacBook Pro models, including today's refreshed entry-level configuration, to its keyboard service program — hopefully out of an abundance of caution.

This means any MacBook Air, inch MacBook Pro, or any Mac with a butterfly keyboard that experiences keyboard issues such as sticky or inconsistently responding keys qualify for free repairs from Apple for up. Apple analyst Ming-Chi Kuo believes Apple will do away with its controversial butterfly mechanism keyboard in future MacBooks, beginning with a refreshed MacBook Air later this year.

In a report obtained by MacRumors, Kuo says Apple will instead use a new keyboard design based on scissor switches, which should provide better key travel and durability than the more failure-prone butterfly keyboard. There have been successful developments in the new scissor keyboard. The new keyboard could improve the typing experience by offering longer key travel and durability by adopting glass fiber to reinforce the keys' structure. Kuo believes a new scissor switch keyboard will also be used in the MacBook Pro, but not until Perhaps tellingly, Kuo made no mention of the inch MacBook Pro he has previously suggested Apple will launch later this year.

Though the butterfly keyboard is still thinner than the new scissor keyboard, we think most users can't tell the difference. Furthermore, the new scissor keyboard could offer a better user experience and benefit Apple's profits; therefore, we predict that the butterfly keyboard may finally disappear in the long term. Apple's butterfly keyboards are highly controversial and have been called out as one of the company's worst design decisions due to their penchant for failure due to small particulates like crumbs or heat issues.

Apple today announced the surprise launch of new 13 and inch MacBook Pro models, which are the fastest Mac notebooks ever at the top of the line. The updated machines feature Intel's 8th and 9th-generation processors, with high-end models featuring eight cores for the first time.

The new inch machines are using updated quad-core processors, with the 6 and 8-core options limited to the inch models. Aside from new processors, the updated MacBook Pro machines continue to feature the same design, despite rumors that Apple would introduce a 16 to There are some internal updates, though. Though not mentioned in the press release, The Loop confirms that the new machine has an updated keyboard. The new keyboard uses a new material that Apple says will cut down on the failure problems that users have seen.

While Apple says the vast majority of its customers are happy with the keyboard, they do take customer complaints seriously, and work to fix any issues. To address the problem, Apple said they changed the material in the keyboard's butterfly mechanism that should substantially reduce problems that some users have seen.

Apple did not explain what the "new materials" in the butterfly keyboard are, but said that the update will significantly cut down on issues like double key presses and missed key. Apple today extended its Keyboard Service Program to all MacBook, MacBook Air, and MacBook Pro models equipped with any generation of its butterfly mechanism keyboard, not long after apologizing over the issues. This means MacBook Air, MacBook Pro, or just-announced MacBook Pro models that experience keyboard issues such as sticky or inconsistently responding keys now qualify for free repairs up to four years after the original purchase date worldwide, regardless of warranty status.

Apple has indicated that most MacBook and MacBook Pro keyboard repairs will be required to be completed at Apple Stores until further notice, rather than being shipped to an off-site Apple repair center, according to an internal memo shared with Apple Store employees last week and obtained by MacRumors. Apple's memo, titled "How to support Mac customers with keyboard-related repairs in store," advises Genius Bar technicians that these keyboard repairs should be "prioritized to provide next-day turnaround time":Most keyboard-related repairs will be required to be completed in store until further notice.

Additional service parts have been shipped to stores to support the increased volume. These repairs should be prioritized to provide next-day turnaround time. When completing the repair, have the appropriate service guide open and carefully follow all repair steps.

Apple did not provide a reason for this change, but the company is known for customer satisfaction, so it could be trying to speed up the process a bit to alleviate frustration. The turnaround time for MacBook and MacBook Pro repairs shipped to Apple's off-site facilities has typically ranged between three to five business days, and sometimes longer, so next-day turnaround would be much more convenient for customers if Genius Bars can actually fulfill that ambitious timeframe.

Shortly after the MacBook and MacBook Pro were released with lower-profile butterfly mechanism keyboards, complaints began to emerge about "sticky" keys causing repeating letters and other inconsistent behavior during. Last year, Apple introduced new MacBook Pro and MacBook Air models with a redesigned third-generation butterfly keyboard that was meant to address issues with sticking and non-responsive keys.

However, as noted by The Wall Street Journal's Joanna Stern, some customers are continuing to experience these issues. Third-generation butterfly keyboard on MacBook Pro via iFixit In a statement, an Apple spokesperson acknowledged the issues and apologized:We are aware that a small number of users are having issues with their third-generation butterfly keyboard and for that we are sorry.

Apple added that affected customers should contact the company for support. Unfortunately, while Apple initiated a service program offering free repairs of affected MacBook and MacBook Pro models with first- and second-generation butterfly keyboards, the latest MacBook Pro and MacBook Air models with third-generation butterfly keyboards do not qualify at this time. Stern wrote her column without using the letters E or R as a clever way of illustrating the problem — there are toggle switches to turn each letter back on.

Humorously, there are also toggle switches to read the article with double E's or double T's, as repeating letters are one symptom of the sticky keys. In an internal document obtained by MacRumors last year, Apple said the third-generation keyboard has a silicone membrane under the keycaps to "prevent debris from entering the butterfly. Apple is exploring a new keyboard design that could eventually replace its butterfly switch MacBook keyboards and finally solve the problem of "sticky" or inconsistently functioning keys.

Issues that Apple has acknowledged can occur with some current MacBook keyboards are widely believed to be caused by dust or other particulates getting lodged in the butterfly mechanism underneath the keycaps, which are shallower than those on previous-generation MacBook and MacBook Pro keyboards with traditional scissor switch mechanisms. In its MacBook Pro models, Apple quietly introduced a thin silicone membrane underneath keyboard keys, which is an attempt to solve the issue of dust and crumbs from getting stuck. But a new patent suggests the company is researching a totally new approach to the way keyboards are designed that could eradicate the problem for good.

Patent and Trademark Office and first spotted by AppleInsider, the patent application called "Computer with keyboard" describes a keyboard that replaces movable keys with a glass sheet that includes raised sections to designate the tactile location of individual keys. When a raised key section is pressed, the keyboard detects the input pressure for that key and processes as a typical key press.

The concept differs from the featureless plain of a virtual onscreen keyboard because the raised sections allow the user to feel where their fingers should rest in relation to the individual keys. Raised glass key concepts from Apple's patent application The patent describes how. Following the release of the new MacBook Pro models, iFixit last week tore apart the inch version and discovered the presence of a new silicone membrane underneath the keyboard's butterfly keys that Apple internal documents have since confirmed has been added to prevent dust and other small particulates from causing key failures.

To give us a better look at the new third-generation butterfly keyboard included in the new machines and how it works, iFixit has done a much deeper dive, exposing the keyboard to debris to test it out. On the MacBook Pro keyboard, the dust settled at the edges of the membrane, leaving the butterfly mechanism of the keys protected. The same test was performed on the MacBook Pro keyboard, demonstrating less protection. Lo and behold, the dust is safely sequestered at the edges of the membrane, leaving the mechanism fairly sheltered.

The holes in the membrane allow the keycap clips to pass through, but are covered by the cap itself, blocking dust ingress. The previous-gen butterfly keys are far less protected, and are almost immediately flooded with our glowing granules. With a combination of a lot of dust and aggressive typing, the dust did penetrate the membrane-covered key clips, hitting the top of the switch, suggesting that there's still a small potential for failure.

While the. It has been an eventful few weeks for MacBook Pro keyboards. Last month, Apple finally acknowledged that a "small percentage" of MacBook and MacBook Pro models with butterfly switch keyboards may experience issues with "sticky" or inconsistently functioning keys, and launched a worldwide service program offering free repairs of affected keyboards for up to four years. The issues are widely believed to be caused by dust or other particulates, like crumbs from a sandwich, getting lodged in the butterfly mechanism underneath the keycaps, which are shallower than those on previous-generation MacBook and MacBook Pro keyboards with traditional scissor switch mechanisms.

Then, last week, Apple surprised us with the release of new MacBook Pro models, which feature an "improved third-generation keyboard for quieter typing," according to Apple's press release. Apple never publicly confirmed if the third-generation keyboard addresses the issues that prompted its service program. It didn't take long for the repair experts at iFixit to open up the latest inch MacBook Pro with Touch Bar and discover a thin silicone membrane underneath each key, which they said is clearly to prevent "contaminant ingress," or, in other words, to prevent dust and crumbs from getting stuck under keys.

Then, just hours ago, MacRumors obtained an internal document from Apple, distributed to its network of Apple Authorized Service Providers, that clearly acknowledges that "the keyboard has a membrane under the keycaps to prevent debris from entering the butterfly mechanism," as many. In an internal document distributed to Apple Authorized Service Providers, obtained by MacRumors from multiple reliable sources, Apple has confirmed that the third-generation keyboard on MacBook Pro models is equipped with a "membrane" to "prevent debris from entering the butterfly mechanism.

The procedure for the space bar replacement has also changed from the previous model. Repair documentation and service videos will be available when keycap parts begin shipping. While the U. Be careful not to tear the membrane.
