Be calm, and search for other similar questions. It happens more than you think. I too passed under that crucible.

Would be nice if you gave us the last four letters of your S/N, to gauge what exactly is your machine and chech if you choose the right one in the menu.

I can see the screws are cramped, but not that cramped. That's enough.

Torx screws are kind of easy to strip, so prevention is in order: your screwdriver is obviously worn out. I stripped badly a Philips 00 with an old jewelry screwdriver, so I bought a new one from a reputable source. If you're not constrained by mailing fees, iFixit has good ones.

Granted you're sure to avoid spills on sensitive parts of the Mac Mini, there are lubricants that loosens screw enough to help in the operations. Otherwise, it's better act without.

But return to the issue you've got at hand. In order of destructivity to the screw and item you'd need to achieve that (I'll give you later the most effective) you may:

  1. If there's still at least a couple of recognizable grooves on the head, poke and pry them with a flat screwdriver, angling it and trying to twist the screw out.
  2. You can also try using a slightly bigger Screwdriver, with a bigger handle and a longer shaft, for more torque
  3. If you've got something to increase the grip, and the screwhead is at least half recognizable, use it. The skin of an old baloon, or some special concoctions you can find on Amazon, acting as a temporary glue. The screwdriver will be able to grip enough to let you loosen the screw, and then you may finish the job with tweezers, pliers or fingers.
  4. Failing all of that, you're entering in the "danger zone", that is, the point where the screw has to be physically damaged and/or you're going to face expenses to let the little bastard go out. First of the danger zone is the '''acquisition of screw extractors'''. They've special heads that burrow in the half-grooves you've left, allowing you to twist them out
  5. Failing that, since the position allow (even if, cramped as it is, it'll need a really strong and firm hand), you could grip them with the ESD Screw Extracting Pliers, the smallest measure. If you've not got handy, you could use a very small wire cutter, but be forewarned that the job will end more messy: while in both cases the screw will end with a dent, bent and squeezed head, the SEP allow for a better grip and torque, the wire cutters, made for a different task, won't, and you'd have to squeeze until they cut a "groove" at the sides of the screw. At that point, you'd likely scratch around the hole (no big deal) and nick the cutters itself, granted the "half-dome" head doesn't make things even harder. The SEP remove that risk.
  6. Failing that, or if you're unwilling to get those items, you could use a Dremel with the smallest rotary cutting head you've got, and cut a slot in the screw. Then you may be able to use a flat screwdriver
  7. Failing that, you could coat an old screwdriver with a tiny amount of Gorilla Grue or strong glue (avoid spilling!!) and let it cure on the screw. Then remove it.
  8. Failing all of the above, but only failing all of the above, use a drill of roughly the same diameter of the screw shaft, and drill the head out, removing the shaft later with pliers.

The safest course of actions passes through the use of the Screw Extractors and the SEP, after evaluating that the screw is unable to be removed with other screwdrivers.

The drill is the last resort, use it only after everything else fails. The glue method and the dremel one seems commonplace, but the Extractors can always be kept for later occurrencies.

Of course, if you evaluate that the screw is not anymore usable, or you go through the most destructive paths, you may need a replacement screw.

Also, if you don't feel confortable with all of the above, there's always the Genius Bar. Granted it's only a matter of loosening a screw, you may get the most helpful in the bunch.

Furthermore, even if you extracted the screw on your own, you may ask if they're willing to give you a spare for a nominal fee. Since screws come in sets, they always have something around for spares.

Very complete answer. +

Hello thank you for your response I gave up on trying to do this myself I just don't have enough information for the rebuild portion. Also I feel really incompetent after stripping that first screw I tried some of those methods and they are not useful due to not being affective in this particular situation I decided to pay the price to have it done at a local shop thanks for your help.

Ps its 3147 mid 2011, thanks

Rebuild is just taking apart in reverse, as most guide say. However, if you don't feel confortable is wise getting assistance.

A word from the wise: hope you did choose a reputable repair shop. It may seem tautology, but an Apple Genius or someone specialized in Apple parts, failing the needed self-help, is the most likely individual to operate on a mac. Especially a machine that's surely less than one year old, and for which an Apple repairman can easily find screws and parts.

I remind you also, whenever you'll feel confortable again, use better instruments. I stripped some screws with a dulled jewelry screwdriver from an economic set, the ones some insurances give for free as gadgets for auto repair.

Then I acquired new screwdrivers from a local vendor, of a reputable brand, and I never had issues again.

This time, let the Apple tech work, next time, build a cache of good instruments of your own.
