Apple ships complete boxes. Nothing is missing, nothing rattles, and everything you need to turn the thing on is in there. Then you set it up and find that the product cannot do the thing you bought it for without one more purchase.
We have run into this three times in the past fortnight, on three different devices, and each time the missing piece was not an accessory. It was the part that made the product work the way the product page implied it already did.
Three we hit ourselves
| What we bought | What it turned out to need |
|---|---|
| A display for an iPad | A trackpad or mouse |
| A dock, for three monitors | A dock and a free Thunderbolt port |
| A Mac with the standard disk | An external SSD, or a plan |
None of those are written anywhere on a box. All three are findable in about ten minutes of using the thing.
A display for an iPad needs a pointer
Connect an iPad to a Studio Display and everything works — the second screen, the speakers, the camera, the microphone, charging over the same cable. We checked fourteen things and could not find one that had stopped working.
Then you try to move a window onto the big screen and discover that the big screen has no touch. Every habit you have for operating an iPad stops at the edge of the small one. You can send a window across with a menu, but resizing it, dragging it, closing it — all of that needs a pointer you did not previously own.
The display works perfectly. It is just that half of your input device is now missing.
A dual-monitor dock is a dual-monitor dock
A dock with four video outputs on the back sounds like four displays. It is two — the connectors are alternatives, not additions. So if you want three screens, the dock alone will not get you there no matter which cables you buy.
The arrangement that works is two into the dock and one straight into the Mac, which means the thing you also needed was a spare Thunderbolt port — something you do not think of as a purchase until the dock has taken the only one you had.
The standard disk assumes you have somewhere else to put things
Every Mac ships with a standard storage configuration, and on a desktop machine that number is smaller than it sounds. It is not wrong — taking a discounted standard machine and adding a drive is often the better deal — but it does assume a decision you have not made yet about where files are going to live.
That assumption is invisible until the disk is full.
The rule that sorts these
Some of what Apple leaves out can be solved later for the same money. Some cannot be solved later at all. Knowing which is which before you pay is the entire skill.
| Fixable later? | Decide when? | |
|---|---|---|
| Memory | Never | Before you pay |
| Chip | Never | Before you pay |
| Storage | Yes — externally | Can wait |
| Input devices | Yes | Can wait |
| Ports and docks | Yes | Can wait |
Everything in the bottom three rows can be bought in a month when you know what you actually need. Everything in the top two is the machine. That is where the money should go, and it is the opposite of how most configuration pages are laid out, which put storage in front of you first because storage is the easiest thing to upsell.
The one that looks permanent and is not
A Studio Display is sold with a choice of stand — tilt only, tilt and height adjustable, or a VESA mount — and Apple’s own fine print says the options are not interchangeable, which reads like a decision you are stuck with.
It is not quite. An Apple Store or authorised service provider can swap the stand after purchase, as a service appointment with a fee that varies by region and by which way you are changing it. So it is not permanent — it is just expensive and inconvenient to change, which is a different thing and worth knowing before you agonise over it at checkout.
We have not done this ourselves, and we are not quoting a price we have not verified. What we can tell you is that “not interchangeable” on the order page does not mean what it appears to mean.
Not every gap is a purchase
It cuts the other way too, and this is the part that gets left out of articles like this one.
The 140W charger for a 16-inch MacBook Pro looks essential. At a desk with a Studio Display it is not: we ran the laptop at full load on the display’s cable alone for half an hour and the battery went up, not down. The second charger people buy for the office is often solving a problem they do not have.
So the question is not “what else does Apple want me to buy”. It is narrower than that: what does this thing need in order to do the job I bought it for, and which of those can I put off until I know?
Before you pay
- Write down the job. Not the product — the thing you want to be doing a week after it arrives. Most missing pieces become obvious when the sentence is specific.
- Spend on what cannot be added. Memory and the chip are the machine. Everything else is a port away.
- Count outputs, not connectors. Four video ports on a dock can still mean two screens.
- Leave one Thunderbolt port free. It is the cheapest expansion you will ever have, and docks eat it first.
- Wait a week on the rest. The accessory you think you need on day one is frequently not the one you end up buying.
What we are not telling you
- We are not recommending products here, and there are no affiliate links on this site. When that changes we will say so on the page it changes on.
- Box contents and stand pricing vary by region and change over time. Check the configuration page for your own country rather than trusting a figure from an article, including this one.
- These are our setups, not a survey. Three devices, one desk. Your work may make a different thing the missing piece.

The three cases described are drawn from our own testing on an iPad Pro with a Studio Display, a MacBook Pro with a UGREEN CM615 dock and three monitors, and a Mac Studio bought in its standard configuration. Stand interchangeability is Apple’s published policy as reported by MacRumors.
