The pentalobe security screw[1] (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, but not limited to, Apple in their products.[1] Pentalobe screws were adopted by Apple starting in 2009, when they were first implemented in the 15-inch MacBook Pro. They have since been used on other MacBook Pro, MacBook Air and iPhone models. Apple attracted criticism upon the introduction of the pentalobe screw; it was seen by some as an attempt to lock individuals out of their devices.[2] However, since then, inexpensive pentalobe screwdrivers, manufactured by third parties, have become relatively easy to obtain.[3]

Pentalobe screw sizes include TS1 (0.8 mm, used on every iPhone after and including the iPhone 4), TS4 (1.2 mm, used on the MacBook Air and the MacBook Pro with Retina display), and TS5 (1.5 mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for the Torq-set screw drive.

MacBook Pro[edit]
The first Apple product to include pentalobe screws internally was the Mid 2009 MacBook Pro 15-inch model. Three pentalobe screws were used to attach the battery to the internal frame. A 1.5 mm flat-blade (slotted) screwdriver could easily remove these screws, which were originally mistaken for 5-point Torx screws.[4] This was the only internal usage of pentalobe screws; all following MacBook Pros use the 'Tri-Wing' security bit to attach the battery to the internal frame, or else have glued-in batteries.
Pentalobe screws reappeared in the mid-2012 version of the MacBook Pro. Eight 3 mm and two 2.3 mm pentalobe screws were used externally to attach the bottom plate of the case to the internal frame.[5] The late-2012 version of the 13-inch MacBook Pro was the first 13-inch model to have pentalobe screws; several were used externally in a similar fashion to the 15-inch mid-2012 MacBook Pro.[6] None of the three 17-inch models of the MacBook Pro have used any pentalobe screws.
MacBook Air[edit]Tool Used For Screws In Bottom Of Macbook
The MacBook Air has seen more extensive use of pentalobe screws than the MacBook Pro. All five versions of the 11-inch MacBook Air (late-2010, mid-2011, mid-2012, mid-2013 and early-2014) include eight 2.5 mm-long and two 8 mm-long external pentalobe screws.[7] The last five versions of the 13-inch MacBook Air (late-2010, mid-2011, mid-2012, mid-2013 and early-2014) use eight 2.6 mm-long and two 9 mm-long pentalobe screws.[8] Pentalobe screws have been used only externally on MacBook Air models.
Third-party manufacturers have marketed a variety of 5-point screwdrivers that fit pentalobe screws on MacBook models since pentalobe screws first appeared externally in the late-2010 MacBook Air.
Huawei[edit]Tool Used For Screws In Bottom Of Machine
Huawei used pentalobe screws for the Huawei P9, a decision criticised by Kyle Wiens writing for Wired, because using pentalobe screws instead of standard screws like Torx, makes electronics more difficult to repair.[9] Its successor, the Huawei P10, also used pentalobe screws to secure the back cover to the phone.
Tool Used For Screws In Bottom Of Macbook AiriPhones[edit]
The original iPhone had no screws holding the body together. The iPhone 3G and the iPhone 3GS had two #00 Phillips screws next to the 30-pin Dock Connector.
Pentalobe screws were first used in the iPhone 4. At first, #00 Phillips screws were used; however, many iPhone 4 models now have pentalobe screws.[10] The screws used are slightly smaller than a Torx TS1, about 0.8 mm. If brought in to an Apple Store for repair, iPhone 4 models with #00 Phillips screws, if any, are replaced with 0.8 mm pentalobe screws.[11] Third-party manufacturers rushed to produce screwdrivers that would remove 0.8 mm pentalobe screws after the iPhone 4's release in June 2010. These inexpensive, easily purchased drivers will remove pentalobe screws quite easily. Many are sold as 'kits' containing a 5-point driver and Phillips #00 screws, in order to replace pentalobe screws with easily removable Phillips screws. Most other security screwdrivers will strip the miniature heads, effectively locking the user out of their device.
All iPhone 4S models contain identical pentalobe screws to those found on the iPhone 4. The iPhone 5 has very similar 0.8 mm pentalobe screws, but the screws have longer 3.6 mm shafts.[12]
Sizes and measurements[edit]
Although there is no (known) official standard naming scheme, the size is commonly known as P-sizes. TS-sizes are sometimes used, but leave room for mixing up with regular Torx sizes. The following P and TS sizes are used by iFixit.com, and PL sizes by Wiha, a German tool company:
These pentalobe, 5 point heads are not to be confused with Torx Plus Security heads which have 6 points.

I'm replacing the RAM in a 2011 MacBook Pro, something I've done before on other machines. Vmware tool for mac os sierra. I got all the screws from the back case off apart from one that sits in the corner on the end by the screen hinge.
After trying with a variety of screwdrivers I cannot get the screw undone, and have now stripped the head of the screw. Any ideas how I can get this screw out?

Whichever method you follow, be very, very careful. The worst case scenario may require drilling the screw out.
Try placing a wide rubber band on the screw and use a slightly bigger screwdriver. Instead of a rubber band, you could also try with a piece of cloth (anything that can provide more grip and change its shape a bit).

This is what i ended up doing, after taking it to the apple store and them battling with it for an hour to no avail - i tried this approach listed on IFIXIT - which didnt work out entirely to plan, but still achieved a similar result.
I bought off amazon this Dremel but the cutting disks where to large for the screw, after searching for fine metal cutting disks i decided that id just use the stock one that came with the Dremel, which i believe is for wood, but anyway.
My approach was to grind away the head of the screw which worked pretty well, what you've got be careful with is the heat this will make and also the vibration so do it in tiny 1 second bursts and let it cool each time, after about 10 or 20 little bursts i grinded away the screw head and most of the surrounding laptop case (i purchased a replacement online prior to doing this as i thought i might break it seeing that the screw was countersunk).

Either way i did this and got the case off, replaced the RAM, screwed down the new bottom cover and booted up the machine.
The only downside in the long run is that there is now 1 screw which cant be removed, as it dosnt have a screw head, but its only 1 of 10 so i dont think its that a big deal.
Be warned though this is a last resort, and not to be taken lightly, i really wouldn't recommend it to any one as the likeliness of breaking your machine is very high, i think i just got lucky.
Heres a pic of the screw after being ground away, as you can see the head of the screw is no longer there and you can just lift off the case.
